+ * libs/gst/base/gstbasetransform.c:
+ basetransform: send delayed events earlier
+ Some elements (such as videorate) might push buffers early,
+ for instance in in transform_ip. We want events (and in particular
+ any NEWSEGMENT event) to be pushed before that.
+ This fixes transmageddon wedging on converting a file starting

- * libs/gst/base/gstbasesrc.c:
- basesrc: do not set first buffer timestamp to 0 for live sources

- for live sources which take time to start up.

- as other buffers do.

+ The idea was originally that if one passed &dest_fmt with
+ dest_fmt=GST_FORMAT_DEFAULT, then the code answering the query
+ could change dest_fmt to the actual default format used. However,
+ in more than half a decade of GStreamer 0.10 no piece of code in
+ GStreamer has ever used that feature, nor are there that many
+ users of this API that actually check whether the format returned
+ is the original format passed before using the values returned.
+ Also, it's just annoying-to-use API in its own right.
+ For all these reasons, make it so that the destination format is
+ passed directly and can't be changed by the element queried.

+ Original commit leads to possibly sending newsegment event downstream

+ are likely to only expect newsegment event following a seek they performed
+ and as such may have their state messed up.

+ when both try to install the same files. When two major versions are
+ in use (e.g. 0.10 and 0.11/1.0), it may be unclear (when looking at
+ things on IRC/pastebin/mailing list etc.) which version is actually
+ being used when there are unversioned wrappers. For all these reasons,

+ pad: rework pad blocking, first part
+ Make pad block call the callback as soon as the pad is not in use. This makes it
+ possible to make sure that when the callback is called, no activity is happening
+ on the pad and that no activity will ever happen until the pad is unblocked
+ again. This makes pad blocking work when there is no dataflow or after EOS and
+ greatly helps dynamic pipelines.
+ Move the probe handling right where we wait on the pad block. The two are
+ related but not the same and the probe can eventually influence the pad
+ blocking as we'll se later.
+ Fix up some broken unit tests or tests that fail with the new behaviour.

+ Reimplement the sticky tags, use a small structure to hold the event and its

+ Events on sinkpads only become active when the event function returned success
+ for the event.
+ When linking, only update events that are different.
+ Avoid making a copy of the event array, use the object lock to protect the event
+ array and release it only to call the event function. This will need to check
+ if something changed, later.
+ Disable a test in the unit test, it can't work yet.

+ when forwarding the downstream caps preference in basetransform

- Windows code paths could need some more work, e.g. we don't clean up

- quite a bit of special-casing and will allow for future improvements/
- extensions that are harder to do if there's a separate subbuffer class.

- grouping

-
-Changes from the 0.8 series to 0.10 series:
-
- * Refcounting and API revised for thread safety, see rules in
- docs/design/part-MT-refcounting.txt
-
- * Scheduling is now done by the elements, they start/stop
- processing threads themselves. This removes the need for
- a separate scheduler.
-
- * State changes now happen from sink to source. This makes sure
- that downstream elements are ready to process data when upstream
- starts producing.
-
- * EOS/ERROR/... does not change the state of elements anymore. This
- means that when the application sets the state on an element, it
- remains in this state.
-
- * GMainLoop integration. Information on the state of the pipeline
- is now received in the mainloop via the GstBus.
-
- * Events move separate from the datastream, this allows for both
- in and out of sync delivery of events.
-
- * Generic _pull() replaced by _pull_region() so that random access
- can be made faster.
-
- * data passing happens from PAUSED, called the preroll phase. In this
- state no data is rendered but it is queued in the sinks.
-
- * negotiation simplified. Caps are now attached to buffers and travel
- along with the datastream.
-
- * GstBuffer is now subclassable.
-
- * Ghostpads now look and feel like real pads.
-
- * New Seeking/flushing policy.
-
- * Addition of base classes and helper functions in the core to abstract
- away the harder parts of plugin development.

-GstBuffer^2
------------
-
-This draft document describes a possible design for arbitrary per-buffer
-metadata.
-
-The proposed changes in this document are not ABI/API compatible with the 0.10
-version of GStreamer and should thus only be considered for upcoming unstable
-versions.
-
-Buffer metadata typically includes properties that give more information about
-the buffer contents. These properties are usually not negotiated and are thus
-not inside the caps.
-
-Some examples of metadata:
-
- - timestamp, duration
- - offset, offset_end
- - interlacing information
- - video alignment, cropping, panning information
- - extra container information such as granulepos, ...
- - extra global buffer properties
-
-
-Requirements
-~~~~~~~~~~~~
-
- - It must be fast
- * allocation, free, low fragmentation
- * access to the metadata fields, preferably not much slower than directly
- accessing a C structure field
- - It must be extensible. Elements should be able to add new arbitrary metadata
- without requiring much effort. Also new metadata fields should not break API
- or ABI.
- - It plays nice with subbuffers. When a subbuffer is created, the various
- buffer metadata should be copied/updated correctly.
- - We should be able to pass metadata in pad_alloc() and get_range() functions
- to specify extra allocation parameters.
- - We should be able to attach statically allocated metadata to a buffer. This
- is for metadata that does not change much.
-
-
-GstMiniObject
-~~~~~~~~~~~~~
-
-We make GstMiniObject a simple refcounted C structure and also a GLib boxed
-type. The following fields will be in the structure:
-
-struct _GstMiniObject {
- GType type;
-
- /*< public >*/ /* with COW */
- /* refcounting */
- gint refcount;
- guint flags;
-
- GstMiniObjectCopyFunction copy;
- GstMiniObjectFreeFunction free;
-}
-
-We will use the regular GSlice allocator or custom object pooling for allocating
-instances of the mini object.
-
-We use the well known refcounting mechanisms to manage the lifetime of the
-objects.
-
-
-GstEvent, GstCaps, GstQuery, GstMessage
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Have the new GstMiniObject be the first field in these objects. They will probably
-also replace the copy and free functions with their own implementations.
-
-Allocation of the objects will use the regular gst_*_new() functions that will
-allocate and initialize a parent GstMiniObject of the required size and setting up
-the custom functions.
-
-
-GstBuffer
-~~~~~~~~~
-
-A GstMiniObject will be the parent instance of the GstBuffer object, which is a
-regular C structure.
-
-struct _GstBuffer {
- GstMiniObject mini_object;
-
- gsize free_size;
-
- GstCaps *caps;
- GstBuffer *parent;
-
- gpointer _gst_padding[10];
-};
-
-The Buffer object will contain a pointer to the parent buffer to allow for subbuffers
-as a first class feature of a GstBuffer.
-
-Allocation of the GstBuffer structure will result in the allocation of a memory region
-of a customizable size (512 bytes). Only the first sizeof (GstBuffer) bytes of this
-region will initially be used. The remaining bytes will be part of the free metadata
-region of the buffer. The size of the free region is kept in the free_size field.
-
-Buffers point to a GstCaps structure that contains the caps of the buffer data.
-
-
-GstBufferMeta
-~~~~~~~~~~~~~
-
-A GstBufferMeta is a structure as follows:
-
- struct _GstBufferMeta {
- GstBufferMetaInfo *info; /* tag and info for the meta item */
- GstBufferMeta *next; /* pointer to the next item */
- }
-
-The purpose of the this structure is to serve as a common header for all metadata
-information that we can attach to a buffer. Specific metadata, such as timing metadata,
-will have this structure as the first field. For example:
-
- struct _GstBufferMetaTiming {
- GstBufferMeta meta; /* common meta header */
-
- GstClockTime dts; /* decoding timestamp */
- GstClockTime pts; /* presentation timestamp */
- GstClockTime duration; /* duration of the data */
- GstClockTime clock_rate; /* clock rate for the above values */
- };
-
-Or another example for the buffer memory region
-
- struct _GstBufferMetaMemory {
- GstBufferMeta meta;
-
- /* pointer to data and its size */
- guint8 *data;
- guint size;
- guint8 *malloc_data;
- GFreeFunc data_free;
- gpointer data_user;
- };
-
-GstBufferMetaInfo will point to more information about the metadata and looks like this:
-
- struct _GstBufferMetaInfo {
- GQuark tag; /* tag name */
- gsize size; /* size of the structure */
-
- GstMetaInitFunction init_func;
- GstMetaFreeFunction free_func;
- GstMetaCopyFunction copy_func;
- GstMetaSubFunction sub_func;
- GstMetaSerializeFunction serialize_func
- GstMetaDeserializeFunction deserialize_func
- GstMetaConvFunction conv_func;
- }
-
-Tag will contain a GQuark of the metadata name. We will be able to refer to specific
-metadata by name or by its (cached) GQuark. A repository of registered MetaInfo
-will be maintained by the core. We will register some common metadata structures
-in core and some media specific info for audio/video/text in -base. Plugins can
-register additional custom metadata.
-
-Along with the metadata description we will have functions to initialize/free (and/or refcount)
-a specific GstBufferMeta instance. We also have the possibility to add a custom subbuffer
-function that can be used to modify the metadata when a subbuffer is taken.
-
-We also add serialize and deserialize function for the metadata in case we need special
-logic for reading and writing the metadata. This is needed for GDP payloading of the
-metadata.
-
-We add a conv function to the Info structure that will be called when a buffer
-should be converted to an old-style buffer for backward compatibility.
-
-The purpose of the separate MetaInfo is to not have to carry the free/init functions in
-each buffer instance but to define them globally. We still want quick access to the info
-so we need to make the buffer metadata point to the info.
-
-Technically we could also specify the field and types in the MetaInfo and
-provide a generic API to retrieve the metadata fields without the need for a
-header file. We will not do this yet.
-
-The complete buffer with metadata would then look as follows:
-
- +-------------------------------------+
-GstMiniObject | GType (GstBuffer) |
- | refcount, flags, copy/free |
- +-------------------------------------+
-GstBuffer | caps, parent, subfunc |
- +.....................................+
- +- | info ------> GstBufferMetaInfo

-
-API examples
-~~~~~~~~~~~~
-
-Buffers are created using the normal gst_buffer_new functions. The standard fields
-are initialized as usual. A memory area that is bigger than the structure size
-is allocated for the buffer metadata. The remaining free area is stored in the
-free_size field.
-
- gst_buffer_new ();
-
-After creating a buffer, the application can set caps. and add other metadata
-information.
-
-In order to modify metadata, a reference to the MetaInfo should be obtained.
-This can be done like this:
-
- GstBufferMetaInfo *info;
-
- info = gst_buffer_meta_get_info (GQuark tag);
-
-Usually the info will be obtained only once in order to avoid lock contention on
-the global pool of meta info. The core will also provide convenience functions
-for the core metainfo.
-
-Once a reference to the info has been obtained, the associated metadata can be
-added or modified on a buffer.
-
-For example, to modify the timing info on a buffer, one could use the following
-sequence:
-
- GstBufferMetaInfo *info;
- GstBufferMetaTiming *timing;
-
- info = gst_buffer_meta_get_info (GST_META_TIMING_QUARK);
-
- timing = gst_buffer_get_meta (buffer, info, TRUE); /* TRUE = create if absent */
- timing->timestamp = 0;
- timing->duration = 20 * GST_MSECOND;
-
-The _get_meta() function returns a pointer to the metadata structure associated
-with the GST_META_TIMING_QUARK info.
-
-For the core meta info, we will provide convenience code that uses the cached
-GstBufferMetaInfo, making the above code a little more simple.
-
- GstBufferMetaTiming *timing;
-
- timing = gst_buffer_get_meta_timing (buffer, TRUE); /* TRUE = create if absent */
- timing->timestamp = 0;
- timing->duration = 20 * GST_MSECOND;
-
-Note that for each of the metadata that we will add to buffers, we need a struct
-definition and a registered MetaInfo.
-
-
-We will also provide an API to iterate the different metainfo structures. A
-possible simple API would look like this:
-
- GstBufferMeta *current = NULL;
-
- /* passing NULL gives the first entry */
- current = gst_buffer_meta_get_next (buffer, current);
-
- /* passing a GstBufferMeta returns the next */
- current = gst_buffer_meta_get_next (buffer, current);
-
-
-
-Memory management
-~~~~~~~~~~~~~~~~~
-
-* allocation
-
- We will initially allocate a reasonable sized GstBuffer structure (say 512
- bytes) and we will set the free_size to the maximum amount of metadata we can
- store.
-
- Since the complete buffer structure, including a large area for metadata, is
- allocated in one go, we can reduce the number of memory allocations while still
- providing dynamic metadata.
-
- When adding metadata, we need to call the init function of the associated
- metadata info structure. Since adding the metadata requires the caller to pass
- a handle to the info, this operation does not require table lookups.
-
- Per-metadata memory initialisation is needed because not all metadata is
- initialized in the same way. We need to, for example, set the timestamps to
- NONE in the MetaTiming structures.
-
- The init/free functions can also be used to implement refcounting for a metadata
- structure. This can be useful when a structure is shared between buffers.
-
- When the free_size of the GstBuffer is exhausted, we will allocate new memory
- for each newly added BufferMeta and use the next pointers to point to this. It
- is expected that this does not occur often and we might be able to optimize
- this transparently in the future.
-
-* free
-
- When a GstBuffer is freed, we potentially might have to call a custom free
- function on the metadata info. In the case of the Memory metadata, we need to
- call the associated free function to free the memory.
-
- When freeing a GstBuffer, the custom buffer free function will iterate all of
- the metadata in the buffer and call the associated free functions in the
- MetaInfo associated with the entries. Usually, this function will be NULL.
-
-
-Subbuffers
-~~~~~~~~~~
-
-Subbuffers are a first class feature of the GstBuffer.
-
-Creating a subbuffer from a GstBuffer will allocate a new GstBuffer and ref the
-parent buffer. It will then iterate all of the metadata entries for the parent
-buffer and call the associated sub_func in the MetaInfo.
-
-This allows each metadata structure to implement the actions needed to update
-the metadata of the subbuffer.
-
-A pointer to the old and new memory location of the metadata is passed to the
-sub_func. The default implementation will simply copy the metadata. Custom
-implementations can adjust the values. For example, when making a subbuffer, the
-timing metadata needs to be reset to NONE when the start offset is different.
-
-
-Serialization
-~~~~~~~~~~~~~
-
-When buffer should be sent over the wire or be serialized in GDP, we need a way
-to perform custom serialization and deserialization on the metadata.
-
-For this we add the serialize and deserialize functions to the metadata info.
-Possible use cases are to make sure we write out the fields with a specific size
-and endianness.
-
-
-Transformations
-~~~~~~~~~~~~~~~
-
-After certain transformations, the metadata on a buffer might not be relevant
-anymore.
-
-Consider, for example, metadata that lists certain regions of interest
-on the video data. If the video is scaled or rotated, the coordinates might not
-make sense anymore. A transform element should be able to adjust or remove the
-associated metadata when it becomes invalid.
-
-We can make the transform element aware of the metadata so that it can adjust or
-remove in an intelligent way. Since we allow arbitrary metadata, we can't do
-this for all metadata and thus we need some other way.
-
-One proposition is to tag the metadata type with keywords that specify what it
-functionally refers too. We could, for example, tag the metadata for the regions
-of interest with a tag that notes that the metadata refers to absolute pixel
-positions. A transform could then know that the metadata is not valid anymore
-when the position of the pixels changed (due to rotation, flipping, scaling and
-so on).
-
-
-Other use cases
-~~~~~~~~~~~~~~~
-
-Making the GstBufferMetaMemory (for making the buffer point to the associated
-memory region) as metadata on a GstBuffer, as opposed to making it an integral
-part of GstBuffer, allows for some more interesting ways to transfer data.
-
-We could for example make a new GstBufferMetaIOVec metadata structure like this:
-
- struct _GstBufferMetaIOVec {
- GstBufferMeta meta;
-
- /* pointer to data and its size */
- GFreeFunc data_free;
- gpointer data_user;
- guint len;
- struct iovec *iov;
- };
-
-This would allow us to transfer data in a scatter/gather array. Since the fields
-in the buffer metadata are now explicit, elements that don't support this kind
-of metadata can gracefully degrade.
-
-Another use case for not having the Memory metadata in the buffers would be for
-_pad_alloc() and get_range(). We can pass a GstBuffer with the requested
-metadata fields to those functions and have the _get_range() or pad_alloc()
-implementations add (or use, in the case of a file reader) the memory metadata.
-
-
-Relationship with GstCaps
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The difference between GstCaps, used in negotiation, and the metadata is not
-clearly defined.
-
-We would like to think of the GstCaps containing the information needed to
-functionally negotiate the format between two elements. The Metadata should then
-only contain variables that can change between each buffer.
-
-For example, for video we would have width/height/framerate in the caps but then
-have the more technical details, such as stride, data pointers, pan/crop/zoom
-etc in the metadata.
-
-A scheme like this would still allow us to functionally specify the desired
-video resolution while the implementation details would be inside the metadata.
-
-
-Compatibility
-~~~~~~~~~~~~~
-
-We need to make sure that elements exchange metadata that they both understand,
-This is particulary important when the metadata describes the data layout in
-memory (such as strides).
-
-Currently the only way to communicate buffer formats between elements is by
-using caps. We would like to use the caps system to negotiate the metadata that
-will be put on buffers.
-
-We would like to add to the caps on the buffer (and pad) an array of metadata
-structures (as strings) that is on the buffer. This way, an element can
-quickly know what metadata to look for.
-
-In order to remain compatibility with older plugins we need to convert buffers
-that use metadata to specify a non-standard data layout to the old format. We
-need to do this before handing buffers to old elements. We will require elements
-that are metadata aware to set a flag on their pads; any buffer passed on that
-pad will be converted to the old layout when the flag is not set.
-
-
-Notes
-~~~~~
-
-Some structures that we need to be able to add to buffers.
-
-* Clean Aperture
-* Arbitrary Matrix Transform
-* Aspect ratio
-* Pan/crop/zoom
-* Video strides
-
-Some of these overlap, we need to find a minimal set of metadata structures that
-allows us to define all use cases.

-Bufferpool
-----------
-
-This document details a possible design for how buffers can be allocated
-and managed in pools.
-
-Bufferpools should increase performance by reducing allocation overhead and
-improving possibilities to implement zero-copy memory transfer.
-
-
-Current Situation
------------------
-
- - elements can choose to implement a pool of buffers. These pools
- can contain buffers for both source and sink pad buffers.
-
- - elements can provide buffers to upstream elements when the upstream element
- requests a buffer with gst_pad_alloc_buffer().
-
- - The buffer pool can preallocate a certain amount of buffers to avoid
- runtime allocation. pad_alloc_buffer() is allowed to block the upstream
- element until buffers are recycled in the pool.
-
- - the pad_alloc_buffer function call can be passed downstream to the sink
- that actually will perform the allocation. A fallback option exists to use
- a default memory bufferpool whe there is no alloc_buffer function installed
- on a pad.
-
- - Upstream renegotiation is performed by making the pad_alloc_buffer function
- return a buffer with new caps.
-
-
-Problems
---------
-
- - There is currently no helper base class to implement efficient buffer pools
- meaning that each element has to implement its own version.
-
- - There is no negotiation between elements about their buffer requirements.
- Upstream elements that decide to use pad_alloc_buffer() can find that the
- buffer they received is not appropriate at all. The most common problem
- is that the buffers don't have the right alignment or insufficient padding.
-
- - There is no negotiation of minimum and maximum amounts of preallocated
- buffers. In order to not avoid deadlocks, this means that buffer pool
- implementations should be able to allocate unlimited amounts of buffers and
- are never allowed to block in pad_alloc_buffer()
-
-
-Requirements
-------------
-
- - maintain and reuse a list of buffers in a reusable base GstBufferPool
- object
-
- - negotiate allocation configuration between source and sink pad.
- - have minimum and maximum amount of buffers with the option of
- preallocating buffers.
- - alignment and padding support
- - arbitrary extra options
-
- - integrate with dynamic caps renegotiation
-
- - dynamically change bufferpool configuration based on pipeline changes.
-
- - allow the application to control buffer allocation
-
-
-GstBufferPool
--------------
-
- The bufferpool object manages a list of buffers with the same properties such
- as size, padding and alignment.
-
- The bufferpool has two states: flushing and non-flushing. In the flushing
- state, the bufferpool can be configured with the required allocation
- preferences. In the non-flushing state, buffers can be retrieved from and
- returned to the pool.
-
- The default implementation of the bufferpool is able to allocate buffers
- from main memory with arbitrary alignment and padding/prefix.
-
- Custom implementations of the bufferpool can override the allocation and
- free algorithms of the buffers from the pool. This should allow for
- different allocation strategies such as using shared memory or hardware
- mapped memory.
-
- The bufferpool object is also used to perform the negotiation of configuration
- between elements.
-
-
-GstPad
-------
-
- The GstPad has a method to query a GstBufferPool and its configuration.
-
- GstBufferPool * gst_pad_query_bufferpool (GstPad * pad);
-
- This function can return a handle to a bufferpool object or NULL when no
- bufferpool object can be provided by the pad.
-
- This function should return a bufferpool object with the
- GstBufferPoolConfig set to the desired parameters of the buffers that will be
- handled by the given pad. This function can only be called on a sinkpad and
- will usually be called by the peer srcpad with the convenience method:
-
- GstBufferPool * gst_pad_peer_query_bufferpool (GstPad * pad);
-
-
- There is also a new function to configure a bufferpool on a pad and its peer
- pad:
-
- gboolean gst_pad_set_bufferpool (GstPad * pad, GstBufferPool *pool);
-
- This function is to inform a pad and its peer pad that a bufferpool should
- be used for allocation (on source pads) and that bufferpool is used by the
- upstream element (on sinkpads).
-
- The currently configured bufferpool can be retrieved with:
-
- GstBufferPool * gst_pad_get_bufferpool (GstPad * pad);
-
- New functions exist to configure these bufferpool functions on pads:
- gst_pad_set_querybufferpool_function and gst_pad_set_setbufferpool_function.
-
-
-negotiating pool and config
----------------------------
-
-Since upstream needs to allocate buffers from a buffer pool, it should first
-negotiate a buffer pool with the downstream element. We propose a simple
-scheme where a sink can propose a bufferpool and some configuration and where
-the source can choose to use this allocator or use its own.
-
-The algorithm for doing this is rougly like this:
-
-
- /* srcpad knows media type and size of buffers and is ready to
- * prepare an output buffer but has no pool yet */
-
- /* first get the pool from the downstream peer */
- pool = gst_pad_peer_query_bufferpool (srcpad);
-
- if (pool != NULL) {
- GstBufferPoolConfig config;
-
- /* clear the pool so that we can reconfigure it */
- gst_buffer_pool_set_flushing (pool, TRUE);
-
- do {
- /* get the config */
- gst_buffer_pool_get_config (pool, &config);

- pool = gst_buffer_pool_new (...);
- }
-
- /* now set the pool on this pad and the peer pad */
- gst_pad_set_bufferpool (pad, pool);
-
-
-Negotiation is the same for both push and pull mode. In the case of pull
-mode scheduling, the srcpad will perform the negotiation of the pool
-when it receives the first pull request.
-
-
-Allocating from pool
---------------------
-
- Buffers are allocated from the pool of a pad:
-
- res = gst_buffer_pool_acquire_buffer (pool, &buffer, ¶ms);
-
- convenience functions to automatically get the pool from a pad can be made:
-
- res = gst_pad_acquire_buffer (pad, &buffer, ¶ms);
-
- Buffers are refcounted in te usual way. When the refcount of the buffer
- reaches 0, the buffer is automatically returned to the pool. This is achieved
- by setting and reffing the pool as a new buffer member.
-
- Since all the buffers allocated from the pool keep a reference to the pool,
- when nothing else is holding a refcount to the pool, it will be finalized
- when all the buffers from the pool are unreffed. By setting the pool to
- the flushing state we can drain all buffers from the pool.
-
-
-Renegotiation
--------------
-
-Renegotiation of the bufferpool might need to be performed when the
-configuration of the pool changes. Changes can be in the buffer size (because
-of a caps change), alignment or number of buffers.
-
-* downstream
-
- When the upstream element wants to negotiate a new format, it might need
- to renegotiate a new bufferpool configuration with the downstream element.
- This can, for example, happen when the buffer size changes.
-
- We can not just reconfigure the existing bufferpool because there might
- still be outstanding buffers from the pool in the pipeline. Therefore we
- need to create a new bufferpool for the new configuration while we let the
- old pool drain.
-
- Implementations can choose to reuse the same bufferpool object and wait for
- the drain to finish before reconfiguring the pool.
-
- The element that wants to renegotiate a new bufferpool uses exactly the same
- algorithm as when it first started.
-
-* upstream
-
- When a downstream element wants to negotiate a new format, it will send a
- RECONFIGURE event upstream. This instructs upstream to renegotiate both
- the format and the bufferpool when needed.
-
- A pipeline reconfiguration is when new elements are added or removed from
- the pipeline or when the topology of the pipeline changes. Pipeline
- reconfiguration also triggers possible renegotiation of the bufferpool and
- caps.
-
- A RECONFIGURE event tags each pad it travels on as needing reconfiguration.
- The next buffer allocation will then require the renegotiation or
- reconfiguration of a pool.
-
- If downstream has specified a RENEGOTIATE flag, it must be prepared to
- received NOT_NEGOTIATED results when allocating buffers, which instructs
- it to start caps and bufferpool renegotiation. When using this flag,
- upstream can more quickly react to downstream format or size changes.
-
-
-Shutting down
--------------
-
- In push mode, a source pad is responsible for setting the pool to the
- flushing state when streaming stops. The flush will unblock any pending
- allocations so that the element can shut down.
-
- In pull mode, the sink element should set the pool to the flushing state when
- shutting down so that the peer _get_range() function can unblock.
-
- In the flushing state, all the buffers that are returned to the pool will
- be automatically freed by the pool and new allocations will fail.
-
-
-
-
-Use cases
----------
-
-1) videotestsrc ! xvimagesink
-
- Before videotestsrc can output a buffer, it needs to negotiate caps and
- a bufferpool with the downstream peer pad.
-
- First it will negotiate a suitable format with downstream according to the
- normal rules.
-
- Then it does gst_pad_peer_query_bufferpool() which triggers the querybufferpool
- function installed on the xvimagesink pad. This bufferpool is currently in
- the flushing state and thus has no buffers allocated.
-
- videotestsrc gets the configuration of the bufferpool object. This
- configuration lists the desired configuration of the xvimagesink, which can
- have specific alignment and/or min/max amount of buffers.
-
- videotestsrc updates the configuration of the bufferpool, it will likely
- set the min buffers to 1 and the size of the desired buffers. It then
- updates the bufferpool configuration with the new properties.
-
- When the configuration is successfully updated, videotestsrc sets the
- bufferpool on its source pad, this will also set the pool on the peer
- sinkpad.
-
- It then sets the bufferpool to the non-flushing state. This preallocates
- the buffers in the pool (if needed). This operation can fail when there
- is not enough memory available. Since the bufferpool is provided by
- xvimagesink, it will allocate buffers backed by an XvImage and pointing
- to shared memory with the X server.
-
- If the bufferpool is successfully activated, videotestsrc can acquire a
- buffer from the pool, set the caps on it, fill in the data and push it
- out to xvimagesink.
-
- xvimagesink can know that the buffer originated from its pool by following
- the pool member or checking the specific GType of it GstBuffer subclass.
- It might need to get the parent buffer first in case of subbuffers.
-
- when shutting down, videotestsrc will set the pool to the flushing state,
- this will cause further allocations to fail and currently allocated buffers
- to be freed. videotestsrc will then free the pool and stop streaming.
-
-
-2) videotestsrc ! queue ! myvideosink
-
- In this second use case we have a videosink that can at most allocate
- 3 video buffers.
-
- Again videotestsrc will have to negotiate a bufferpool with the peer
- element. For this it will perform gst_pad_peer_query_bufferpool() which
- queue will proxy to its downstream peer element.
-
- The bufferpool returned from myvideosink will have a max_buffers set to 3.
- queue and videotestsrc can operate with this upper limit because none of
- those elements require more than that amount of buffers for temporary
- storage.
-
- The bufferpool of myvideosink will then be configured with the size of the
- buffers for the negotiated format and according to the padding and alignment
- rules. When videotestsrc sets the pool to non-flushing, the 3 video
- buffers will be preallocated in the pool.
-
- The pool will then be configured on the src of videotestsrc and the
- sinkpad of the queue. The queue will proxy the setbufferpool method to
- its srcpad, which finally configures the pool all the way to the sink.
-
- videotestsrc acquires a buffer from the configured pool on its srcpad and
- pushes this into the queue. When the videotestsrc has acquired and pushed
- 3 frames, the next call to gst_buffer_pool_acquire_buffer() will block
- (assuming the GST_BUFFER_POOL_FLAG_WAIT is specified).
-
- When the queue has pushed out a buffer and the sink has rendered it, the
- refcount of the buffer reaches 0 and the buffer is recycled in the pool.
- This will wake up the videotestsrc that was blocked, waiting for more
- buffers and will make it produce the next buffer.
-
- In this setup, there are at most 3 buffers active in the pipeline and
- the videotestsrc is rate limited by the rate at which buffers are recycled
- in the bufferpool.
-
- When shutting down, videotestsrc will first set the bufferpool on the srcpad
- to flushing. This causes any pending (blocked) acquire to return with a
- WRONG_STATE result and causes the streaming thread to pause.
-
-
-3) .. ! myvideodecoder ! queue ! fakesink
-
- In this case, the myvideodecoder requires buffers to be aligned to 128
- bytes and padded with 4096 bytes. The pipeline starts out with the
- decoder linked to a fakesink but we will then dynamically change the
- sink to one that can provide a bufferpool.
-
- When it negotiates the size with the downstream element fakesink, it will
- receive a NULL bufferpool because fakesink does not provide a bufferpool.
- It will then select it own custom bufferpool to start the datatransfer.
-
- At some point we block the queue srcpad, unlink the queue from the
- fakesink, link a new sink, set the new sink to the PLAYING state and send
- the right newsegment event to the sink. Linking the new sink would
- automatically send a RENEGOTIATE event upstream and, through queue, inform
- myvideodecoder that it should renegotiate its bufferpool because downstream
- has been reconfigured.
-
- Before pushing the next buffer, myvideodecoder would renegotiate a new
- bufferpool. To do this, it performs the usual bufferpool negotiation
- algorithm. If it can obtain and configure a new bufferpool from downstream,
- it sets its own (old) pool to flushing and unrefs it. This will eventually
- drain and unref the old bufferpool.
-
- The new bufferpool is set as the new bufferpool for the srcpad and sinkpad
- of the queue and set to the non-flushing state.
-
-
-4) .. ! myvideodecoder ! queue ! myvideosink
-
- myvideodecoder has negotiated a bufferpool with the downstream myvideosink
- to handle buffers of size 320x240. It has now detected a change in the
- video format and need to renegotiate to a resolution of 640x480. This
- requires it to negotiate a new bufferpool with a larger buffersize.
-
- When myvideodecoder needs to get the bigger buffer, it starts the
- negotiation of a new bufferpool. It queries a bufferpool from downstream,
- reconfigures it with the new configuration (which includes the bigger buffer
- size), it sets the bufferpool to non-flushing and sets the bufferpool as
- the new pool for the srcpad and its peer. This automatically flushes the
- old pool and unrefs it, which causes the old format to drain.
-
- It then uses the new bufferpool for allocating new buffers of the new
- dimension.
-
- If at some point, the decoder wants to switch to a lower resolution again,
- it can choose to use the current pool (which has buffers that are larger
- than the required size) or it can choose to renegotiate a new bufferpool.
-
-
-5) .. ! myvideodecoder ! videoscale ! myvideosink
-
- myvideosink is providing a bufferpool for upstream elements and wants to
- change the resolution.
-
- myvideosink sends a RENEGOTIATE event upstream to notify upstream that a
- new format is desirable. upstream elements try to negotiate a new format
- and bufferpool before pushing out a new buffer. The old bufferpools are
- drained in the regular way.
-
-
-

actually be used to update the slider bar.

DESIGN
~~~~~~
The same flow works as well for any chain of multiple elements and might
be implemented with a helper function in the future.
-
-Issues
-~~~~~~
-
-When an EOS event has passed a pad and the pad is set to blocked, the block will
-never happen because no data is going to flow anymore. One possibility is to
-keep track of the pad's EOS state and make the block succeed immediately. This is
-not yet implemenented.
-
-When dynamically reconnecting pads, some events (like NEWSEGMENT, EOS,
-TAGS, ...) are not yet retransmitted to the newly connected element. It's
-unclear if this can be done by core automatically by caching those events and
-resending them on a relink. It might also be possible that this needs a
-GstFlowReturn value from the event function, in which case the implementation
-must be delayed for after 0.11, when we can break API/ABI.

+GstBuffer
+---------
+
+This document describes the design for buffers.
+
+A GstBuffer is the object that is passed from an upstream element to a
+downstream element and contains memory and metadata information.
+
+Requirements
+~~~~~~~~~~~~
+
+ - It must be fast
+ * allocation, free, low fragmentation
+ - Must be able to attach multiple memory blocks to the buffer
+ - Must be able to attach artibtrary metadata to buffers
+ - efficient handling of subbuffer, copy, span, trim
+
+Writability
+-----------
+
+The Buffers is writable when the refcount is 1. This means that:
+
+ - metadata can be added/removed and the metadata can be changed
+ - GstMemory blocks can be added/removed
+
+The individual memory blocks have their own refcounting and READONLY flags
+that might influence their writability.
+
+Buffers can be made writable with gst_buffer_make_writable(). This will copy the
+buffer with the metadata and will ref the memory in the buffer. This means that
+the memory is not automatically copied when copying buffers.
+
+
+Managing GstMemory
+------------------
+
+A GstBuffer contains an array of pointers to GstMemory objects.
+
+When the buffer is writable, gst_buffer_take_memory() can be used to add a
+new GstMemory object to the buffer. When the array of memory is full, memory
+will be merged to make room for the new memory object.
+
+gst_buffer_n_memory() is used to get the amount of memory blocks on the
+GstBuffer.
+
+With gst_buffer_peek_memory(), memory can be retrieved from the memory array.
+The desired access pattern for the memory block should be specified so that
+appropriate checks can be made and, in case of GST_MAP_WRITE, a writable copy
+can be constructed when needed.
+
+gst_buffer_remove_memory_range() and gst_buffer_remove_memory() can be used to
+remove memory from the GstBuffer.
+
+
+Subbuffers
+----------
+
+Subbuffers are made by copying only a region of the memory blocks and copying
+all of the metadata.
+
+
+Span
+----
+
+Spanning will merge together the data of 2 buffers into a new buffer
+
+
+Data access
+-----------
+
+ Accessing the data of the buffer can happen by retrieving the individual
+ GstMemory objects in the GstBuffer or my using the gst_buffer_map() and
+ gst_buffer_unmap() function.
+
+ The _map and _unmap function will always return the memory of all blocks as one
+ large contiguous region of memory. Using the _map and _unmap function might be
+ more convenient that accessing the individual memory blocks at the expense of
+ being more expensive because it might perform memcpy operations.
+
+ For buffers with only one GstMemory object (the most common case), _map and
+ _unmap have no performance penalty at all.
+
+
+* Read access with 1 memory block
+
+ The memory block is accessed and mapped for read access.
+ The memory block is unmapped after usage
+
+* write access with 1 memory block
+
+ The buffer should be writable or this operation will fail..
+ The memory block is accessed. If the memory block is readonly, a copy is made
+ and the original memory block is replaced with this copy. then the memory
+ block is mapped in write mode.
+ The memory block is unmapped after usage.
+
+* Read access with multiple memory blocks
+
+ The memory blocks are combined into one large memory block. If the buffer is
+ writable, The memory blocks are replace with this new memory block. If the
+ buffer is not writable, the memory is returned as is.
+ The memory block is then mapped in read mode.
+
+ When the memory is unmapped after usage and the buffer has multiple memory
+ blocks, this means that the map operation was not able to store the combined
+ buffer and it thus returned memory that should be freed. Otherwise, the memory
+ is unmapped.
+
+* Write access with multiple memory blocks
+
+ The buffer should be writable or the operation fails. The memory blocks are
+ combined into one large memory block and the existing blocks are replaced with
+ this new block. The memory is then mapped in write mode.
+ The memory is unmapped after usage.
+
+
+Use cases

+
+Generating RTP packets from h264 video
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+We receive as input a GstBuffer with an encoded h264 image and we need to
+create RTP packets containing this h264 data as the payload. We typically need
+to fragment the h264 data into multiple packets, each with their own RTP and
+payload specific header.

+ +-+ +-------+ +-+ +-------+ +-+ +-------+
+ : : : :
+ \-----------/ \-----------/
+ buffer 1 buffer 2
+
+The output buffer array consists of x buffers consisting of an RTP payload header
+and a subbuffer of the original input H264 buffer. Since the rtp headers and
+the h264 data don't need to be contiguous in memory, they are added to the buffer
+as separate GstMemory blocks and we can avoid to memcpy the h264 data into
+contiguous memory.
+
+A typical udpsink will then use something like sendmsg to send the memory regions
+on the network inside one UDP packet. This will further avoid having to memcpy
+data into contiguous memory.
+
+Using bufferlists, the complete array of output buffers can be pushed in one
+operation to the peer element.

-Buffer Lists
-------------
-
-GstBuffer provides a datastructure to manage:
-
- - a continuous region of memory
- - functions to copy/free the memory
- - metadata associated with that memory such as timestamps and caps.
-
-It is the primary means of transfering data between pads and elements.
-
-GstBufferList expands on GstBuffer to allow multiple GstBuffers (conceptually
-organized in a list) to be treated as a multiple groups of GstBuffers. This allows
-for the following extra functionality:
-
- - A logical GstBuffer (called a group) can consist of disjoint memory each with
- their own copy/free and metadata. Logically the group should be treated as
- one single GstBuffer.
- - Multiple groups can be put into one bufferlist. This allows for a single
- method call to pass multiple (logical) buffers downstream.
-
-
-Use cases
-~~~~~~~~~
-
-A typical use case for multimedia pipelines is to append or remove 'headers'
-from packets of data.
-
-Generating RTP packets from h264 video
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-We receive as input a GstBuffer with an encoded h264 image and we need to
-create RTP packets containing this h264 data as the payload. We typically need
-to fragment the h264 data into multiple packets, each with their own RTP and

-
-The output bufferlist consists of x groups consisting of an RTP payload header
-and a subbuffer of the original input H264 buffer. Since the rtp headers and
-the h264 data don't need to be contiguous in memory, we can avoid to memcpy the
-h264 data into the rtp packets.
-
-Since we can generate a bufferlist with multiple groups, we can push all the
-RTP packets for the input data to the next element in one operation.
-
-A typical udpsink will then use something like sendmsg to send the groups on
-the network inside one UDP packet. This will further avoid having to memcpy
-data into contiguous memory.
-
-
-API
-~~~
-
-The GstBufferList is an opaque data structure and is operated on using an
-iterator. It derives from GstMiniObject so that it has basic refcounting and
-copy/free functions.
-
-The bufferlist is writable when its refcount is 1 and it's not marked as
-readonly. A writable bufferlist means that elements can be added and removed
-form the list but it does not mean that the actual buffers in the list are
-writable.
-
-To modify the data in the buffers of the bufferlist, both the list and the
-buffer must be writable.
-
-Methods exist for navigating the groups in the list and the buffers inside a
-group.
-
-
-Metadata
-~~~~~~~~
-
-Each of the buffers inside the bufferlist can have metadata associated with it.
-
-The metadata of the bufferlist is always the metadata of the first buffer of the
-first group in the bufferlist. This means that:
-
- - Before pushing the list to a pad, negotiation happens with (only) the caps of
- the first buffer in the list. Caps of other buffers is ignore.
-
- - synchronisation happens on the timestamp of the first buffer in the list.
-
-This allows for efficient (re)timestamping and re-typing (caps) of a group of
-buffers without having to modify each of the buffer's metadata.

+Bufferpool
+----------
+
+This document details the design of how buffers are be allocated and
+managed in pools.
+
+Bufferpools increases performance by reducing allocation overhead and
+improving possibilities to implement zero-copy memory transfer.
+
+Together with the ALLOCATION query, elements can negotiate allocation properties
+and bufferpools between themselves. This also allows elements to negotiate
+buffer metadata between themselves.
+
+Requirements
+------------
+
+ - Provide a GstBufferPool base class to help the efficient implementation of a
+ list of reusable GstBuffer objects.
+
+ - Let upstream elements initiate the negotiation of a bufferpool and it
+ configuration. Allow downstream elements provide bufferpool properties and/or
+ a bufferpool. This includes the following properties:
+
+ * have minimum and maximum amount of buffers with the option of
+ preallocating buffers.
+ * alignment and padding support
+ * buffer metadata
+ * arbitrary extra options
+
+ - Integrate with dynamic caps renegotiation.
+
+ - Notify upstream element of new bufferpool availability. This is important
+ when a new element, that can provide a bufferpool, is dynamically linked
+ downstream.
+
+
+GstBufferPool
+-------------
+
+ The bufferpool object manages a list of buffers with the same properties such
+ as size, padding and alignment.
+
+ The bufferpool has two states: active and inactive. In the in-active
+ state, the bufferpool can be configured with the required allocation
+ preferences. In the active state, buffers can be retrieved from and
+ returned to the pool.
+
+ The default implementation of the bufferpool is able to allocate buffers
+ from main memory with arbitrary alignment and padding/prefix.
+
+ Custom implementations of the bufferpool can override the allocation and
+ free algorithms of the buffers from the pool. This should allow for
+ different allocation strategies such as using shared memory or hardware
+ mapped memory.
+
+
+Negotiation
+-----------
+
+ After a particular media format has been negotiated between two pads (using the
+ CAPS event), they must agree on how to allocate buffers.
+
+ The srcpad will always take the initiative to negotiate the allocation
+ properties. It starts with creating a GST_QUERY_ALLOCATION with the negotiated
+ caps.
+
+ The srcpad can set the need-pool flag to TRUE in the query to optionally make the
+ peer pad allocate a bufferpool.
+
+ It will then inspect the returned results and configure the returned pool or
+ create a new pool with the returned properties when needed.
+
+ Buffers are then allocated by the srcpad from the negotiated pool and pushed to
+ the peer pad as usual.
+
+ The allocation query can also return an allocator name when the buffers are of
+ different sizes and can't be allocated from a pool.
+
+
+Allocation query
+----------------
+
+ The allocation query has the following fields:
+
+ (in) "caps", GST_TYPE_CAPS
+ - the caps that was negotiated
+
+ (in) "need-pool", G_TYPE_BOOLEAN
+ - if a GstBufferPool is requested
+
+ (out) "size", G_TYPE_UINT
+ - the total size of the buffer memory. This size is set to 0 when the
+ buffers are of variable size.
+
+ (out) "min-buffers", G_TYPE_UINT
+ - the minimum amount of buffers to allocate
+
+ (out) "max-buffers", G_TYPE_UINT
+ - the maximum amount of buffers to allocate
+
+ (out) "prefix", G_TYPE_UINT
+ - the prefix of the buffer memory
+
+ (out) "align", G_TYPE_UINT
+ - the aligment of the memory in the buffers, the alignment will be applied
+ to the prefix. The aligment is expressed as a value ((1 << N) - 1).
+ Alignment will be done on multiples of (1 << N).
+
+ (out) "pool", GST_TYPE_BUFFER_POOL
+ - a buffer pool when need-pool was TRUE and the peer can provide a pool.
+ This pool is inactive and can be configured when needed.
+
+ (out) "metadata", G_TYPE_VALUE_ARRAY of G_TYPE_STRING
+ - an array of metadata API strings that can be accepted.
+
+ (out) "allocator", G_TYPE_VALUE_ARRAY of G_TYPE_STRING
+ - an array of allocators that can be used.
+
+
+Allocating from pool
+--------------------
+
+ Buffers are allocated from the pool of a pad:
+
+ res = gst_buffer_pool_acquire_buffer (pool, &buffer, ¶ms);
+
+ A GstBuffer that is allocated from the pool will always be writable (have a
+ refcount of 1) and it will also have its pool member point to the GstBufferPool
+ that created the buffer.
+
+ Buffers are refcounted in the usual way. When the refcount of the buffer
+ reaches 0, the buffer is automatically returned to the pool.
+
+ Since all the buffers allocated from the pool keep a reference to the pool,
+ when nothing else is holding a refcount to the pool, it will be finalized
+ when all the buffers from the pool are unreffed. By setting the pool to
+ the inactive state we can drain all buffers from the pool.
+
+ When the pool is in the inactive state, gst_buffer_pool_acquire_buffer() will
+ return GST_FLOW_WRONG_STATE immediately.
+
+ Extra parameters can be given to the gst_buffer_pool_acquire_buffer() method to
+ influence the allocation decision. GST_BUFFER_POOL_FLAG_KEY_UNIT and
+ GST_BUFFER_POOL_FLAG_DISCONT serve as hints.
+
+ When the bufferpool is configured with a maximum number of buffers, allocation
+ will block when all buffers are outstanding until a buffer is returned to the
+ pool. This behaviour can be changed by specifying the
+ GST_BUFFER_POOL_FLAG_DONTWAIT flag in the parameters. With this flag set,
+ allocation will return GST_FLOW_UNEXPECTED when the pool is empty.
+
+
+Renegotiation
+-------------
+
+Renegotiation of the bufferpool might need to be performed when the
+configuration of the pool changes. Changes can be in the buffer size (because
+of a caps change), alignment or number of buffers.
+
+* downstream
+
+ When the upstream element wants to negotiate a new format, it might need
+ to renegotiate a new bufferpool configuration with the downstream element.
+ This can, for example, happen when the buffer size changes.
+
+ We can not just reconfigure the existing bufferpool because there might
+ still be outstanding buffers from the pool in the pipeline. Therefore we
+ need to create a new bufferpool for the new configuration while we let the
+ old pool drain.
+
+ Implementations can choose to reuse the same bufferpool object and wait for
+ the drain to finish before reconfiguring the pool.
+
+ The element that wants to renegotiate a new bufferpool uses exactly the same
+ algorithm as when it first started. It will negotiate caps first then use the
+ ALLOCATION query to get and configure the new pool.
+
+* upstream
+
+ When a downstream element wants to negotiate a new format, it will send a
+ RECONFIGURE event upstream. This instructs upstream to renegotiate both
+ the format and the bufferpool when needed.
+
+ A pipeline reconfiguration is when new elements are added or removed from
+ the pipeline or when the topology of the pipeline changes. Pipeline
+ reconfiguration also triggers possible renegotiation of the bufferpool and
+ caps.
+
+ A RECONFIGURE event tags each pad it travels on as needing reconfiguration.
+ The next buffer allocation will then require the renegotiation or
+ reconfiguration of a pool.
+
+
+Shutting down
+-------------
+
+ In push mode, a source pad is responsible for setting the pool to the
+ inactive state when streaming stops. The inactive state will unblock any pending
+ allocations so that the element can shut down.
+
+ In pull mode, the sink element should set the pool to the inactive state when
+ shutting down so that the peer _get_range() function can unblock.
+
+ In the inactive state, all the buffers that are returned to the pool will
+ automatically be freed by the pool and new allocations will fail.
+
+
+Use cases
+---------
+
+1) videotestsrc ! xvimagesink
+
+ Before videotestsrc can output a buffer, it needs to negotiate caps and
+ a bufferpool with the downstream peer pad.
+
+ First it will negotiate a suitable format with downstream according to the
+ normal rules. It will send a CAPS event downstream with the negotiated
+ configuration.
+
+ Then it does an ALLOCATION query. It will use the returned bufferpool or
+ configures its own bufferpool with the returned parameters. The bufferpool is
+ initially in the inactive state.
+
+ The ALLOCATION query lists the desired configuration of the downstream
+ xvimagesink, which can have specific alignment and/or min/max amount of
+ buffers.
+
+ videotestsrc updates the configuration of the bufferpool, it will likely
+ set the min buffers to 1 and the size of the desired buffers. It then
+ updates the bufferpool configuration with the new properties.
+
+ When the configuration is successfully updated, videotestsrc sets the
+ bufferpool to the active state. This preallocates the buffers in the pool
+ (if needed). This operation can fail when there is not enough memory
+ available. Since the bufferpool is provided by xvimagesink, it will allocate
+ buffers backed by an XvImage and pointing to shared memory with the X server.
+
+ If the bufferpool is successfully activated, videotestsrc can acquire a
+ buffer from the pool, fill in the data and push it out to xvimagesink.
+
+ xvimagesink can know that the buffer originated from its pool by following
+ the pool member.
+
+ when shutting down, videotestsrc will set the pool to the inactive state,
+ this will cause further allocations to fail and currently allocated buffers
+ to be freed. videotestsrc will then free the pool and stop streaming.
+
+
+2) videotestsrc ! queue ! myvideosink
+
+ In this second use case we have a videosink that can at most allocate
+ 3 video buffers.
+
+ Again videotestsrc will have to negotiate a bufferpool with the peer
+ element. For this it will perform the ALLOCATION query which
+ queue will proxy to its downstream peer element.
+
+ The bufferpool returned from myvideosink will have a max_buffers set to 3.
+ queue and videotestsrc can operate with this upper limit because none of
+ those elements require more than that amount of buffers for temporary
+ storage.
+
+ The bufferpool of myvideosink will then be configured with the size of the
+ buffers for the negotiated format and according to the padding and alignment
+ rules. When videotestsrc sets the pool to active, the 3 video
+ buffers will be preallocated in the pool.
+
+ videotestsrc acquires a buffer from the configured pool on its srcpad and
+ pushes this into the queue. When the videotestsrc has acquired and pushed
+ 3 frames, the next call to gst_buffer_pool_acquire_buffer() will block
+ (assuming the GST_BUFFER_POOL_FLAG_DONTWAIT is not specified).
+
+ When the queue has pushed out a buffer and the sink has rendered it, the
+ refcount of the buffer reaches 0 and the buffer is recycled in the pool.
+ This will wake up the videotestsrc that was blocked, waiting for more
+ buffers and will make it produce the next buffer.
+
+ In this setup, there are at most 3 buffers active in the pipeline and
+ the videotestsrc is rate limited by the rate at which buffers are recycled
+ in the bufferpool.
+
+ When shutting down, videotestsrc will first set the bufferpool on the srcpad
+ to inactive. This causes any pending (blocked) acquire to return with a
+ WRONG_STATE result and causes the streaming thread to pause.
+
+
+3) .. ! myvideodecoder ! queue ! fakesink
+
+ In this case, the myvideodecoder requires buffers to be aligned to 128
+ bytes and padded with 4096 bytes. The pipeline starts out with the
+ decoder linked to a fakesink but we will then dynamically change the
+ sink to one that can provide a bufferpool.
+
+ When it negotiates the size with the downstream element fakesink, it will
+ receive a NULL bufferpool because fakesink does not provide a bufferpool.
+ It will then select its own custom bufferpool to start the datatransfer.
+
+ At some point we block the queue srcpad, unlink the queue from the
+ fakesink, link a new sink and set the new sink to the PLAYING state.
+ Linking the new sink would automatically send a RECONFIGURE event upstream
+ and, through queue, inform myvideodecoder that it should renegotiate its
+ bufferpool because downstream has been reconfigured.
+
+ Before pushing the next buffer, myvideodecoder would renegotiate a new
+ bufferpool. To do this, it performs the usual bufferpool negotiation
+ algorithm. If it can obtain and configure a new bufferpool from downstream,
+ it sets its own (old) pool to inactive and unrefs it. This will eventually
+ drain and unref the old bufferpool.
+
+ The new bufferpool is set as the new bufferpool for the srcpad and sinkpad
+ of the queue and set to the active state.
+
+
+4) .. ! myvideodecoder ! queue ! myvideosink
+
+ myvideodecoder has negotiated a bufferpool with the downstream myvideosink
+ to handle buffers of size 320x240. It has now detected a change in the
+ video format and need to renegotiate to a resolution of 640x480. This
+ requires it to negotiate a new bufferpool with a larger buffersize.
+
+ When myvideodecoder needs to get the bigger buffer, it starts the
+ negotiation of a new bufferpool. It queries a bufferpool from downstream,
+ reconfigures it with the new configuration (which includes the bigger buffer
+ size) and it then sets the bufferpool to active. The old pool is inactivated
+ and unreffed, which causes the old format to drain.
+
+ It then uses the new bufferpool for allocating new buffers of the new
+ dimension.
+
+ If at some point, the decoder wants to switch to a lower resolution again,
+ it can choose to use the current pool (which has buffers that are larger
+ than the required size) or it can choose to renegotiate a new bufferpool.
+
+
+5) .. ! myvideodecoder ! videoscale ! myvideosink
+
+ myvideosink is providing a bufferpool for upstream elements and wants to
+ change the resolution.
+
+ myvideosink sends a RECONFIGURE event upstream to notify upstream that a
+ new format is desirable. upstream elements try to negotiate a new format
+ and bufferpool before pushing out a new buffer. The old bufferpools are
+ drained in the regular way.
+
This function describes the possible types that the pad can handle or
produce (see part-pads.txt and part-negotiation.txt).
-Caps are also attached to buffers to describe to content of the data
-pointed to be the buffer.

Various methods exist to work with the media types such as subtracting

+Controller
+----------
+
+The controller subsystem allows to automate element property changes. It works
+so that all parameter changes are time based and elements request property
+updates at processing time.
+
+Element view
+~~~~~~~~~~~~
+Elements don't need to do much. They need to:
+- mark object properties that can be changed while processing with
+ GST_PARAM_CONTROLLABLE
+- call gst_object_sync_values (self, timestamp) in the processing function
+ before accessing the parameters.
+
+All ordered property types can be automated (int, double, boolean, enum).
+
+Application view
+~~~~~~~~~~~~~~~~
+Applications need to setup the property automation. For that they need to create
+a GstControlSource and attach it to a property using GstControlBinding. Various
+control-sources and control-bindings exist. All control sources produce control
+value sequences in the form of gdouble values. The control bindings map them to
+the value range and type of the bound property.
+
+One control-source can be attached to one or more properties at the same time.
+If it is attached multiple times, then each control-binding will scale and
+convert the control values to the target property type and range.
+
+One can create complex control-curves by using a GstInterpolationControlSource.
+This allows the classic user editable control-curve (often seen in audio/video
+editors). Another way is to use computed control curves. GstLFOControlSource can
+generate various repetitive signals. Those can be made more complex by chaining
+the control sources. One can attach another control-source to e.g. modulate the
+frequency of the first GstLFOControlSource.
+
+In most cases GstControlBindingDirect will be the binding to be used. Other
+control bindings are there to handle special cases, such as having 1-4 control-
+sources and combine their values into a single guint to control a rgba-color
+property.
Typical (re)negotiation of the transform element in push mode always goes from
sink to src, this means triggers the following sequence:
- - the sinkpad receives a buffer with new caps, this triggers the setcaps
- function on the sinkpad before handing the buffer to transform.
+ - the sinkpad receives a new caps event.
- the transform function figures out what it can convert these caps to.
- try to see if we can configure the caps unmodified on the peer. We need to
do this because we prefer to not do anything.
We call this downstream negotiation (DN) and it goes roughly like this:
sinkpad transform srcpad

the same as the case with the same-caps negotiation. (DCC)
We can immediately observe that the copy transform states will need to
-allocate a buffer from a downstream element using pad-alloc. When the transform
-element is receiving a non-writable buffer in the in-place state, it will also
-need to perform a pad-alloc. There is no reason why the passthrough state would
-perform a pad-alloc. This is important because upstream re-negotiation can only
-happen when the transform uses pad-alloc for all outgoing buffers.
+allocate a new buffer from the bufferpool. When the transform element is
+receiving a non-writable buffer in the in-place state, it will also
+need to perform an allocation. There is no reason why the passthrough state would
+perform an allocation.
This steady state changes when one of the following actions occur:
- the sink pad receives new caps, this triggers the above downstream
renegotation process, see above for the flow.
- - the src pad is instructed to produce new caps because of new caps from
- pad-alloc, this only happens when the transform calls pad-alloc on the
- srcpad in order to produce a new output buffer.
- the transform element wants to renegotiate (because of changed properties,
for example). This essentially clears the current steady state and
- triggers the downstream and upstream renegotiation process.
-
-Parallel to the downstream negotiation process there is an upstream negotiation
-process. The handling and proxy of buffer-alloc is the most comple part of the
-transform element. This upstream negotiation process has 3 cases: (UN)
-
- - upstream calls the buffer-alloc function of the transform sinkpad and this
- call is proxied downstream (UNP)
- - upstream calls the buffer-alloc function of the transform sinkpad, the
- transform does not proxy the call but returns a buffer itself (UNU)
- - the transform calls the pad-alloc function downstream to allocate a new
- output buffer (but not because of a proxied buffer-alloc) (UNA)
-
-The case where the pad-alloc is called because an output buffer must be
-generated in the chain function is handled above in the copy-transform and the
-in-place transform when the input buffer is not writable or the input buffer
-size is smaller than the output size.
-
-We are left with the last case (proxy an incoming pad-alloc or not). We have 2
-possibilities here:
-
- - pad-alloc is called with the same caps as are currently being handled by
- the transform on the sinkcaps. Note that this will only be true when the
- transform element is completely negotiated because of data processing, see
- above. Then the element is not yet negotiated, we proceed with the case
- where sinkcaps are different from thos in the buffer-alloc.
-
- * If the transform is using copy-transform, we don't need to proxy because
- we will call pad-alloc when generating an output buffer.

+After the transform element is configured with caps, a bufferpool needs to be
+negotiated to perform the allocation of buffers. We habe 2 cases:
- - pad-alloc is called with different caps than are currently being handled by
- the transform on the sinkcaps we have to try to negotiate a new
- configuration for the transform element.
+ - The element is operating in passthrough we don't need to allocate a buffer
+ in the transform element.
+ - The element is not operating in passthrough and needs to allocation an
+ output buffer.
- * we perform the standard way to finding a best transform using
- find_transform() and we call the pad-alloc function with these caps.
- If we get different caps from pad-alloc, we find the best format to
- transform these to and return those caps instead.
+In case 1, we don't query and configure a pool. We let upstream decide if it
+wants to use a bufferpool and then we will proxy the bufferpool from downstream
+to upstream.
+In case 2, we query and set a bufferpool on the srcpad that will be used for
+doing the allocations.

For performance reasons, the mapping between caps and size is kept in a cache.
-
-Issues
-~~~~~~
-
-passthrough and in-place transforms (with writable buffers) never need to
-perform a pad-alloc on the srcpad. This means that if upstream negotiation
-happens, the transform element will never know about it.
-
-The transform element will keep therefore track of the allocation pattern of
-the peer elements. We can see the following cases:
-
-- upstream peer calls buffer-alloc on the sinkpad of the transform. In some
- cases (see above) this call gets proxied or not.
-
-- upstream peer does never call buffer-alloc.
-
-We will keeps state about this allocation pattern and perform the following in
-each case respectively:
-
-- Upstream calls buffer-alloc: In passthrough and (some) in-place we proxy
- this call onto the downstream element. If the caps are changed, we mark
- a flag that we will require a new pad-alloc for the output of the next
- output buffer.
-
-- upstream peer does not call buffer-alloc: We always perform a pad-alloc
- when processing buffers. We can further optimize by only looking at the
- returned caps instead of doing a full, needless buffer copy.

+src pads
+--------
+
+A gst_pad_push_event() on a srcpad will first store the event in the sticky
+array before sending the event to the peer pad. If there is no peer pad, the
+gst_pad_push_event() function returns NOT_LINKED.
+
+Note that the behaviour is not influenced by a flushing pad.
+
+FLUSH_START and FLUSH_STOP events are dropped on blocked pads.
+
+sink pads
+---------
+
+A gst_pad_send_event() on a sinkpad will check the new event against the
+existing event. If they are different, the new event is stored as a pending
+event. If the events are the same, nothing changes.
+
+When the pad is flushing, the _send_event() function returns WRONG_STATE
+immediately.
+
+The event function is then called for all pending events. If the function
+returns success, the pending event is copied to the active events, else the
+pending event is removed and the current active event is unchanged.
+
+This ensures that the event function is never called for flushing pads and that
+the sticky array only contains events for which the event function returned
+success.
+
+
+pad link
+--------
+
+When linking pads, all the sticky events from the srcpad are copied to the
+pending array on the sinkpad. The pending events will be sent to the event
+function of the sinkpad on the next event or buffer.

+GstMemory
+---------
+
+This document describes the design of the memory objects.
+
+GstMemory objects are usually added to GstBuffer objects and contain the
+multimedia data passed around in the pipeline.
+
+Requirements
+~~~~~~~~~~~~
+
+ - It must be possible to have different memory allocators
+ - It must be possible to efficiently share memory objects, copy, span
+ and trim.
+
+
+Allocators
+~~~~~~~~~~
+
+ GstMemory objects are created by allocators. Allocators are registered to the
+ memory system with a set of methods contained in a GstMemoryInfo structure.
+
+ struct _GstMemoryInfo {
+ GstMemoryAllocFunction alloc;
+ GstMemoryGetSizesFunction get_sizes;
+ GstMemoryResizeFunction resize;
+ GstMemoryMapFunction map;
+ GstMemoryUnmapFunction unmap;
+ GstMemoryFreeFunction free;
+
+ GstMemoryCopyFunction copy;
+ GstMemoryShareFunction share;
+ GstMemoryIsSpanFunction is_span;
+
+ gpointer user_data;
+ };
+
+ After an allocator is registerd, new GstMemory can be created with
+
+ GstMemory * gst_allocator_alloc (const GstAllocator * allocator,
+ gsize maxsize, gsize align);
+
+ The GstMemory object is a refcounted object that must be freed with
+ gst_memory_unref ().
+
+ It is also possible to create a new GstMemory object that wraps existing
+ memory with:
+
+ GstMemory * gst_memory_new_wrapped (GstMemoryFlags flags, gpointer data,
+ GFreeFunc free_func, gsize maxsize,
+ gsize offset, gsize size);
+
+Lifecycle
+~~~~~~~~~
+
+GstMemory objects are refcounted. When the GstMemory object is first created, it
+has a refcount of 1.
+
+Each variable holding a reference to the GstMemory object is responsible for
+updating the refcount.
+
+The refcount determines the writability of the object. If the refcount > 1, it is
+by definition used by multipled objects and thus cannot be safely written to.
+
+When the refcount reaches 0, and thus no objects hold a reference anymore, we
+can free the memory. The GstMemoryFreeFunction of the allocator will be called
+to cleanup the memory.
+
+
+Memory layout
+~~~~~~~~~~~~~
+
+ GstMemory manages a memory region. The accesible part of the managed region is
+ defined by an offset relative to the start of the region and a size. This
+ means that the managed region can be larger than what is visible to the user of
+ GstMemory API.
+
+ Schematically, GstMemory has a pointer to a memory region of _maxsize_. The area
+ starting from _offset_ and _size_ is accessible.
+
+ memory
+ GstMemory ->*----------------------------------------------------*
+ ^----------------------------------------------------^
+ maxsize
+ ^--------------------------------------^
+ offset size
+
+ The current properties of the accessible memory can be retrieved with:
+
+ gsize gst_memory_get_sizes (GstMemory *mem, gsize *offset, gsize *maxsize);
+
+ The offset and size can be changed with:
+
+ void gst_memory_resize (GstMemory *mem, gssize offset, gsize size);
+
+ The memory object is always readable. The memory block is writable when:
+
+ - the refcount is exactly 1
+ - the memory object has no parent, or if it has a parent, the parent is
+ writable.
+ - the memory object is not marked as READONLY.
+
+
+Data Access
+~~~~~~~~~~~
+
+ Access to the memory region is always controlled with a map and unmap method
+ call. This allows the implementation to monitor the access patterns or set up
+ the required memory mappings when needed.
+
+ Mapping a memory region requires the caller to specify the access method: READ
+ and/or WRITE. For write access, the GstMemory object must be writable.
+
+ After the data has been accessed in the object, the unmap call must be
+ performed. The call will update the new memory size with the specified size.
+
+ It is allowed to map multiple times with different access modes. for each of
+ the map calls, an corresponding unmap call needs to be made. WRITE-only memory
+ cannot be mapped in READ mode and READ-only memory cannot be mapped in WRITE
+ mode.
+
+ The memory pointer returned from the map call is guaranteed to remain valid in
+ the requested mapping mode until the corresponding unmap call is performed on
+ the pointer.
+
+ When multiple map operations are nested and return the same pointer, the pointer
+ is valid until the last unmap call is done.
+
+ When the final reference on a memory object is dropped, all outstanding
+ mappings are automatically unmapped.
+
+ Resizing a GstMemory does not influence any current mappings an any way. Note
+ however that the unmap call can resize the buffer again.
+
+
+Copy
+~~~~
+
+ A GstMemory copy can be made with the gst_memory_copy() call. Normally,
+ allocators will implement a custom version of this function to make a copy of
+ the same kind of memory as the original one.
+
+ This is what the fallback version of the copy function will do, albeit slower
+ than what as custom implementation could do.
+
+ The copy operation is only required to copy the visible range of the memory
+ block.
+
+
+Share
+~~~~~
+
+ A memory region can be shared between GstMemory object with the
+ gst_memory_share() operation.

+

to pause in order to play a higher priority stream.
+GST_MESSAGE_STEP_START:
+

+
+ A buffer was dropped or an element changed its processing strategy for
+ Quality of Service reasons.

+GstMeta
+-------
+
+This document describes the design for arbitrary per-buffer metadata.
+
+Buffer metadata typically describes the lowlevel properties of the buffer
+content. These properties are typically not negotiated with caps but they are
+negotiated in the bufferpools.
+
+Some examples of metadata:
+
+ - timestamp, duration
+ - offset, offset_end
+ - interlacing information
+ - video alignment, cropping, panning information
+ - extra container information such as granulepos, ...
+ - extra global buffer properties
+
+
+Requirements
+~~~~~~~~~~~~
+
+ - It must be fast
+ * allocation, free, low fragmentation
+ * access to the metadata fields, preferably not much slower than directly
+ accessing a C structure field
+ - It must be extensible. Elements should be able to add new arbitrary metadata
+ without requiring much effort. Also new metadata fields should not break API
+ or ABI.
+ - It plays nice with subbuffers. When a subbuffer is created, the various
+ buffer metadata should be copied/updated correctly.
+ - We should be able to negotiate metadata between elements
+
+Use cases
+---------
+
+ * Video planes
+
+ Video data is sometimes allocated in non-contiguous planes for the Y and the UV
+ data. We need to be able to specify the data on a buffer using multiple
+ pointers in memory. We also need to be able to specify the stride for these
+ planes.
+
+ * Extra buffer data
+
+ Some elements might need to store extra data for a buffer. This is typically
+ done when the resources are allocated from another subsystem such as OMX or
+ X11.
+
+ * Processing information
+
+ Pan and crop information can be added to the buffer data when the downstream
+ element can understand and use this metadata. An imagesink can, for example,
+ use the pan and cropping formation when it blits the image on the screen
+ with little overhead.
+
+
+GstMeta
+~~~~~~~
+
+A GstMeta is a structure as follows:
+
+ struct _GstMeta {
+ const GstMetaInfo *info; /* tag and info for the meta item */
+ };
+
+The purpose of the this structure is to serve as a common header for all metadata
+information that we can attach to a buffer. Specific metadata, such as timing metadata,
+will have this structure as the first field. For example:
+
+ struct _GstMetaTiming {
+ GstMeta meta; /* common meta header */
+
+ GstClockTime dts; /* decoding timestamp */
+ GstClockTime pts; /* presentation timestamp */
+ GstClockTime duration; /* duration of the data */
+ GstClockTime clock_rate; /* clock rate for the above values */
+ };
+
+Or another example for the video memory regions that consists of both fields and
+methods.
+
+
+ #define GST_VIDEO_MAX_PLANES 4
+
+ struct GstMetaVideo {
+ GstMeta meta;
+
+ GstBuffer *buffer;
+
+ GstVideoFlags flags;
+ GstVideoFormat format;
+ guint width;
+ guint height;
+
+ guint n_planes;
+ gsize offset[GST_VIDEO_MAX_PLANES]; /* offset in the buffer memory region of the
+ * first pixel. */
+ gint stride[GST_VIDEO_MAX_PLANES]; /* stride of the image lines. Can be negative when
+ * the image is upside-down */
+
+ gpointer (*map) (GstMetaVideo *meta, guint plane, gint *stride,
+ GstMapFlags flags);
+ gboolean (*unmap) (GstMetaVideo *meta, guint plane, gpointer data);
+ };
+
+ gpointer gst_meta_video_map (GstMetaVideo *meta, guint plane, gint *stride,
+ GstMapflags flags);
+ gboolean gst_meta_video_unmap (GstMetaVideo *meta, guint plane, gpointer data);
+
+GstMeta derived structures define the API of the metadata. The API can consist of
+fields and/or methods. It is possible to have different implementations for the
+same GstMeta structure.
+
+The implementation of the GstMeta api would typically add more fields to the
+public structure that allow it to implement the API.
+
+GstMetaInfo will point to more information about the metadata and looks like this:
+
+ struct _GstMetaInfo {
+ GQuark api; /* api name */
+ GType type; /* implementation type */
+ gsize size; /* size of the structure */
+
+ GstMetaInitFunction init_func;
+ GstMetaFreeFunction free_func;
+ GstMetaCopyFunction copy_func;
+ GstMetaTransformFunction transform_func;
+ };
+
+api will contain a GQuark of the metadata api. A repository of registered MetaInfo
+will be maintained by the core. We will register some common metadata structures
+in core and some media specific info for audio/video/text in -base. Plugins can
+register additional custom metadata.
+
+For each implementation of api, there will thus be a unique GstMetaInfo. In the
+case of metadata with a well defined API, the implementation specific init
+function will setup the methods in the metadata structure. A unique GType will
+be made for each implementation and stored in the type field.
+
+Along with the metadata description we will have functions to initialize/free (and/or refcount)
+a specific GstMeta instance. We also have the possibility to add a custom
+transform function that can be used to modify the metadata when a transformation
+happens.
+
+There are no explicit methods to serialize and deserialize the metadata. Since
+each type has a GType, we can reuse the GValue transform functions for this.
+
+The purpose of the separate MetaInfo is to not have to carry the free/init functions in
+each buffer instance but to define them globally. We still want quick access to the info
+so we need to make the buffer metadata point to the info.
+
+Technically we could also specify the field and types in the MetaInfo and
+provide a generic API to retrieve the metadata fields without the need for a
+header file. We will not do this yet.
+
+Allocation of the GstBuffer structure will result in the allocation of a memory region
+of a customizable size (512 bytes). Only the first sizeof (GstBuffer) bytes of this
+region will initially be used. The remaining bytes will be part of the free metadata
+region of the buffer. Different implementations are possible and are invisible
+in the API or ABI.
+
+The complete buffer with metadata could, for example, look as follows:
+
+ +-------------------------------------+
+GstMiniObject | GType (GstBuffer) |
+ | refcount, flags, copy/disp/free |
+ +-------------------------------------+
+GstBuffer | caps, parent, pool |
+ +.....................................+

+
+API examples
+~~~~~~~~~~~~
+
+Buffers are created using the normal gst_buffer_new functions. The standard fields
+are initialized as usual. A memory area that is bigger than the structure size
+is allocated for the buffer metadata.
+
+ gst_buffer_new ();
+
+After creating a buffer, the application can set caps and add metadata
+information.
+
+To add or retrieve metadata, a handle to a GstMetaInfo structure needs to be
+obtained. This defines the implementation and API of the metadata. Usually, a
+handle to this info structure can be obtained by calling a public _get_info()
+method from a shared library (for shared metadata).
+
+The following defines can usually be found in the shared .h file.
+
+ GstMetaInfo * gst_meta_timing_get_info();
+ #define GST_META_TIMING_INFO (gst_meta_timing_get_info())
+
+Adding metadata to a buffer can be done with the gst_buffer_add_meta() call.
+This function will create new metadata based on the implementation specified by
+the GstMetaInfo. It is also possible to pass a generic pointer to the add_meta()
+function that can contain parameters to initialize the new metadata fields.
+
+Retrieving the metadata on a buffer can be done with the
+gst_buffer_meta_get() method. This function retrieves an existing metadata
+conforming to the API specified in the given info. When no such metadata exists,
+the function will return NULL.
+
+ GstMetaTiming *timing;
+
+ timing = gst_buffer_get_meta (buffer, GST_META_TIMING_INFO);
+
+Once a reference to the info has been obtained, the associated metadata can be
+added or modified on a buffer.
+
+ timing->timestamp = 0;
+ timing->duration = 20 * GST_MSECOND;
+
+Other convenience macros can be made to simplify the above code:
+
+ #define gst_buffer_get_meta_timing(b) \
+ ((GstMetaTiming *) gst_buffer_get_meta ((b), GST_META_TIMING_INFO)
+
+This makes the code look like this:
+
+ GstMetaTiming *timing;
+
+ timing = gst_buffer_get_meta_timing (buffer);
+ timing->timestamp = 0;
+ timing->duration = 20 * GST_MSECOND;
+
+To iterate the different metainfo structures, one can use the
+gst_buffer_meta_get_next() methods.
+
+ GstMeta *current = NULL;
+
+ /* passing NULL gives the first entry */
+ current = gst_buffer_meta_get_next (buffer, current);
+
+ /* passing a GstMeta returns the next */
+ current = gst_buffer_meta_get_next (buffer, current);
+
+
+Memory management
+~~~~~~~~~~~~~~~~~
+
+* allocation
+
+ We initially allocate a reasonable sized GstBuffer structure (say 512 bytes).
+
+ Since the complete buffer structure, including a large area for metadata, is
+ allocated in one go, we can reduce the number of memory allocations while still
+ providing dynamic metadata.
+
+ When adding metadata, we need to call the init function of the associated
+ metadata info structure. Since adding the metadata requires the caller to pass
+ a handle to the info, this operation does not require table lookups.
+
+ Per-metadata memory initialisation is needed because not all metadata is
+ initialized in the same way. We need to, for example, set the timestamps to
+ NONE in the MetaTiming structures.
+
+ The init/free functions can also be used to implement refcounting for a metadata
+ structure. This can be useful when a structure is shared between buffers.
+
+ When the free_size of the GstBuffer is exhausted, we will allocate new memory
+ for each newly added Meta and use the next pointers to point to this. It
+ is expected that this does not occur often and we might be able to optimize
+ this transparently in the future.
+
+* free
+
+ When a GstBuffer is freed, we potentially might have to call a custom free
+ function on the metadata info. In the case of the Memory metadata, we need to
+ call the associated free function to free the memory.
+
+ When freeing a GstBuffer, the custom buffer free function will iterate all of
+ the metadata in the buffer and call the associated free functions in the
+ MetaInfo associated with the entries. Usually, this function will be NULL.
+
+
+Serialization
+~~~~~~~~~~~~~
+
+When buffer should be sent over the wire or be serialized in GDP, we need a way
+to perform custom serialization and deserialization on the metadata.
+
+for this we can use the GValue transform functions.
+
+
+Transformations
+~~~~~~~~~~~~~~~
+
+After certain transformations, the metadata on a buffer might not be relevant
+anymore.
+
+Consider, for example, metadata that lists certain regions of interest
+on the video data. If the video is scaled or rotated, the coordinates might not
+make sense anymore. A transform element should be able to adjust or remove the
+associated metadata when it becomes invalid.
+
+We can make the transform element aware of the metadata so that it can adjust or
+remove in an intelligent way. Since we allow arbitrary metadata, we can't do
+this for all metadata and thus we need some other way.
+
+One proposition is to tag the metadata type with keywords that specify what it
+functionally refers too. We could, for example, tag the metadata for the regions
+of interest with a tag that notes that the metadata refers to absolute pixel
+positions. A transform could then know that the metadata is not valid anymore
+when the position of the pixels changed (due to rotation, flipping, scaling and
+so on).
+
+
+Subbuffers
+~~~~~~~~~~
+
+Subbuffers are implemented with a generic copy. Parameters to the copy
+are the offset and size. This allows each metadata structure to implement the
+actions needed to update the metadata of the subbuffer.
+
+It might not make sense for some metadata to work with subbuffers. For example
+when we take a subbuffer of a buffer with a video frame, the GstMetaVideo
+simply becomes invalid and is removed from the new subbuffer.
+
+
+Relationship with GstCaps
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The difference between GstCaps, used in negotiation, and the metadata is not
+clearly defined.
+
+We would like to think of the GstCaps containing the information needed to
+functionally negotiate the format between two elements. The Metadata should then
+only contain variables that can change between each buffer.
+
+For example, for video we would have width/height/framerate in the caps but then
+have the more technical details, such as stride, data pointers, pan/crop/zoom
+etc in the metadata.
+
+A scheme like this would still allow us to functionally specify the desired
+video resolution while the implementation details would be inside the metadata.
+
+
+Compatibility
+~~~~~~~~~~~~~
+
+We need to make sure that elements exchange metadata that they both understand,
+This is particulary important when the metadata describes the data layout in
+memory (such as strides).
+
+We would like to use the bufferpool negotiation system to negotiate the possible
+metadata that can be exchanged between elements.
+
+When deciding the allocation properties, we will also negotiate the buffer
+metadata structures that we can exchange.
+
+
+Notes
+~~~~~
+
+Some structures that we need to be able to add to buffers.
+
+* Clean Aperture
+* Arbitrary Matrix Transform
+* Aspect ratio
+* Pan/crop/zoom
+* Video strides
+
+Some of these overlap, we need to find a minimal set of metadata structures that
+allows us to define all use cases.
The basics of negotiation are as follows:
- - GstCaps (see part-caps.txt) are refcounted before they
- are attached to a buffer to describe the contents of the buffer.
- It is possible to add a NULL caps to a buffer, this means that the
- buffer type did not change relative to the previous buffer. If no
- previous buffer was received by a downstream element, it is free to
- discard the buffer.
-
- - Before receiving a buffer, an element must check if the datatype of
- the buffer has changed. The element should reconfigure itself to the
- new format before processing the buffer data. If the data type on
- the buffer is not acceptable, the element should refuse the buffer by
+ - GstCaps (see part-caps.txt) are refcounted before they are pushed as
+ an event to describe the contents of the following buffer.
+
+ - An element should reconfigure itself to the new format received as a CAPS
+ event before processing the following buffers. If the data type in the
+ caps event is not acceptable, the element should refuse the buffer by
returning an appropriate GST_FLOW_NOT_NEGOTIATED return value from the
chain function.
- The core will automatically call the set_caps function for this purpose
- when it is installed on the sink or source pad.
-
- - When requesting a buffer from a bufferpool, the preferred type should
- be passed to the buffer allocation function. After receiving a buffer
- from a bufferpool, the datatype should be checked again.
-
- - A bufferpool allocation function should try to allocate a buffer of the
- preferred type. If there is a good reason to choose another type, the
- alloc function should see if that other type is accepted by the other
- element, then allocate a buffer of that type and attach the type to the
- buffer before returning it.
+ - Downstream elements can request a format change of the stream by sending a
+ RECONFIGURE event upstream. Upstream elements will renegotiate a new format
+ when they receive a RECONFIGURE event.

Use case:
2) When does negotiation happen?
- before srcpad does a push, it figures out a type as stated in 1), then
- it calls the pad alloc function with the type. The sinkpad has to
- create a buffer of that type, src fills the buffer and sends it to sink.
+ it pushes a caps event with the type. The sink checks the media type and
+ configures itself for this type.
+ - the source then usually does an ALLOCATION query to negotiate a bufferpool
+ with the sink. It then allocates a buffer from the pool and pushes it to
+ the sink. since the sink accepted the caps, it can create a pool for the
+ format.
- since the sink stated in 1) it could accept the type, it will be able to
- create a buffer of the type and handle it.
- - sink checks media type of buffer and configures itself for this type.
+ handle it.
3) How can sink request another format?
- sink asks if new format is possible for the source.
- - sink returns buffer with new type in allocfunction.
- - src receives buffer with new type, reconfigures and pushes.
- - sink can always select something it can create and handle since it takes
- the initiative. src should be able to handle the new type since it said
- it could accept it.
+ - sink pushes RECONFIGURE event upstream
+ - src receives the RECONFIGURE event and marks renegotiation
+ - On the next buffer push, the source renegotiates the caps and the
+ bufferpool. The sink will put the new new prefered format high in the list
+ of caps it returns from its getcaps function.
videotestsrc ! queue ! xvimagesink

- - queue contains buffers with different types.
+ - queue proxies the bufferpool
+ - queue proxies the RECONFIGURE event
+ - queue stores CAPS event in the queue. This means that the queue can contain
+ buffers with different types.
Pull-mode negotiation
The pull thread is usually started in the PAUSED->PLAYING state change. We must
be able to complete the negotiation before this state change happens.
-The time to do capsnego, then, is after _check_pull_range() has succeeded,
+The time to do capsnego, then, is after the SCHEDULING query has succeeded,
but before the sink has spawned the pulling thread.
^^^^^^^^^
The sink determines that the upstream elements support pull based scheduling by
-calling gst_pad_check_pull_range().
+doing a SCHEDULING query.
The sink initiates the negotiation process by intersecting the results

+Probes
+------
+
+ Probes are callbacks that can be installed by the application and will notify
+ the application about the states of the dataflow.
+
+
+Requirements
+------------
+
+Applications should be able to monitor and control the dataflow on pads. We
+identify the following types:
+
+ - be notified when the pad is/becomes idle and make sure the pad stays idle.
+ This is essential to be able to implement dynamic relinking of elements
+ without breaking the dataflow.
+
+ - be notified when data or events are pushed or sent on a pad. It should also
+ be possible to inspect and modify the data.
+
+ - be able to drop, pass and block on data based on the result of the callback.
+
+ - be able to drop, pass data on blocking pads based on methods performed by
+ the application thread.
+
+
+Overview
+--------
+
+ The function gst_pad_add_probe() is used to add a probe to a pad. It accepts a
+ probe type mask and a callback.
+
+ gulong gst_pad_add_probe (GstPad *pad,
+ GstPadProbeType mask,
+ GstPadProbeCallback callback,
+ gpointer user_data,
+ GDestroyNotify destroy_data);
+
+ The function returns a gulong that uniquely identifies the probe and that can
+ be used to remove the probe with gst_pad_remove_probe():
+
+ void gst_pad_remove_probe (GstPad *pad, gulong id);
+
+ The mask parameter is a bitwise or of the following flags:
+
+ typedef enum
+ {
+ GST_PAD_PROBE_TYPE_INVALID = 0,
+
+ /* flags to control blocking */
+ GST_PAD_PROBE_TYPE_IDLE = (1 << 0),
+ GST_PAD_PROBE_TYPE_BLOCK = (1 << 1),
+
+ /* flags to select datatypes */
+ GST_PAD_PROBE_TYPE_BUFFER = (1 << 2),
+ GST_PAD_PROBE_TYPE_BUFFER_LIST = (1 << 3),
+ GST_PAD_PROBE_TYPE_EVENT_DOWNSTREAM = (1 << 4),
+ GST_PAD_PROBE_TYPE_EVENT_UPSTREAM = (1 << 5),
+
+ /* flags to select scheduling mode */
+ GST_PAD_PROBE_TYPE_PUSH = (1 << 6),
+ GST_PAD_PROBE_TYPE_PULL = (1 << 7),
+
+ } GstPadProbeType;
+
+ When adding a probe with the IDLE or BLOCK flag, the probe will become a
+ blocking probe (see below). Otherwise the probe will be a DATA probe.
+
+ The datatype and scheduling selector flags are used to select what kind of
+ datatypes and scheduling modes should be allowed in the callback.
+
+ The blocking flags must match the triggered probe exactly.
+
+ The probe callback is defined as:
+
+ GstPadProbeReturn (*GstPadProbeCallback) (GstPad *pad, GstPadProbeInfo *info,
+ gpointer user_data);
+
+ A probe info structure is passed as an argument and its type is guaranteed
+ to match the mask that was used to register the callback. The data item in the
+ info contains type specific data, which is usually the data item that is blocked
+ or NULL when no data item is present.
+
+ The probe can return any of the following return values:
+
+ typedef enum
+ {
+ GST_PAD_PROBE_DROP,
+ GST_PAD_PROBE_OK,
+ GST_PAD_PROBE_REMOVE,
+ GST_PAD_PROBE_PASS,
+ } GstPadProbeReturn;
+
+ GST_PAD_PROBE_OK is the normal return value. DROP will drop the item that is
+ currently being probed. GST_PAD_PROBE_REMOVE the currently executing probe from the
+ list of probes.
+
+ GST_PAD_PROBE_PASS is relevant for blocking probes and will temporarily unblock the
+ pad and let the item trough, it will then block again on the next item.
+
+
+Blocking probes
+---------------
+
+ Blocking probes are probes with BLOCK or IDLE flags set. They will always
+ block the dataflow and trigger the callback according to the following rules:
+
+ When the IDLE flag is set, the probe callback is called as soon as no data is
+ flowing over the pad. If at the time of probe registration, the pad is idle,
+ the callback will be called immediately from the current thread. Otherwise,
+ the callback will be called as soon as the pad becomes idle in the streaming
+ thread.
+
+ The IDLE probe in useful to perform dynamic linking, it allows to wait for for
+ a safe moment when an unlink/link operation can be done. Since the probe is a
+ blocking probe, it will also make sure that the pad stays idle until the probe
+ is removed.
+
+ When the BLOCK flag is set, the probe callback will be called when new data
+ arrives on the pad and right before the pad goes into the blocking state. This
+ callback is thus only called when there is new data on the pad.
+
+ The blocking probe is removed with gst_pad_remove_probe() or when the probe
+ callback return GST_PAD_PROBE_REMOVE. In both cases, and if this was the last
+ blocking probe on the pad, the pad is unblocked and dataflow can continue.
+
+
+Non-Blocking probes
+--------------------
+
+ Non-blocking probes or DATA probes are probes triggered when data is flowing
+ over the pad. The are called after the blocking probes are run and always with
+ data.
+
+
+Push dataflow
+-------------
+
+Push probes have the GST_PAD_PROBE_TYPE_PUSH flag set in the callbacks.
+
+In push based scheduling, the blocking probe is called first with the data item.
+Then the data probes are called before the peer pad chain or event function is
+called.
+
+The data probes are called before the peer pad is checked. This allows for
+linking the pad in either the BLOCK or DATA probes on the pad.
+
+Before the peerpad chain or event function is called, the peer pad block and
+data probes are called.
+
+Finally, the IDLE probe is called on the pad after the data was sent to the
+peer pad.
+
+The push dataflow probe behavior is the same for buffers and bidirectional events.

+
+Pull dataflow
+-------------
+
+Pull probes have the GST_PAD_PROBE_TYPE_PULL flag set in the callbacks.
+
+The gst_pad_pull_range() call will first trigger the BLOCK probes without a DATA
+item. This allows the pad to be linked before the peer pad is resolved. It also
+allows the callback to set a data item in the probe info.
+
+After the blocking probe and the getrange function is called on the peer pad
+and there is a data item, the DATA probes are called.
+
+When control returns to the sinkpad, the IDLE callbacks are called. The IDLE
+callback is called without a data item so that it will also be called when there
+was an error.
+
+If there is a valid DATA item, the DATA probes are called for the item.

The getrange function is called when a peer pad performs a _pull_range() on the pad. This
downstream pad can be a pulling element or another _pull_range() based element.
+
+Scheduling Query

+
+A sinkpad can ask the upstream srcpad for its scheduling attributes. It does
+this with the SCHEDULING query.

+
+ _SEEKABLE:
+ - the offset of a pull operation can be specified, if this flag is false,
+ the offset should be -1,

-the gst-feedback command to your bug report.
-If you're having problem with a specific application (either one of ours,
-somebody else's, or your own), please also provide a log of gst-mask by
-running
-<programlisting>
-myapp --gst-mask=-1 > mask.log 2>&1
-gzip mask.log
-</programlisting>
-(interrupting the program if it doesn't stop by itself)
-and attach mask.log.gz to your bug report.

If the application you are having problems with is segfaulting, then
provide us with the necessary gdb output. See

+Plan for 0.11
+=============
+
+First attempt at making a list of tasks in roughly chronological order.
+
+* General cleanup
+
+ - Remove deprecated methods
+ - Cleanup structs + PADDING
+ - ..
+
+ This should allow us to continue expanding later in the same way that 0.10 was
+ expanded.
+
+
+* Review GstCaps fields
+
+ - go over caps fields for audio, video, compressed media-type etc
+
+ We need to express things with less fields. This would speed up caps, make
+ them less verbose and speed up some elements.
+
+
+* Add GstFlowReturn for events (and query)
+
+ This would allow us to know more precisely what went wrong.
+
+ http://cgit.freedesktop.org/~wtay/gstreamer/log/?h=events2
+
+
+* add return structure for events and query
+
+ Make events return more information. (a seek event might want to return the
+ final position of the keyframe seek and the accuracy of the seek)
+
+ Make bindings easiers. Currently the writability of a query depends on the
+ refcount being exactly 1. If the query is not writable, it simply cannot be
+ answered.
+
+
+* Make GstMiniObject a simple boxed type
+
+ - Move copy and free function to structure
+ - convert GstBuffer, GstEvent, GstMessage, GstQuery,
+
+ We don't need to subclass miniobjects when we have arbitrary metadata.
+
+ Allocation should be more efficient and buffer/metadata/data can be allocated
+ and pooled in one contiguous memory area.
+
+ Typechecking of various types is much more efficient when there is only
+ one class.
+
+ http://cgit.freedesktop.org/~wtay/gstreamer/log/?h=miniobject2
+
+
+* Convert GstCaps to GstMiniObject
+
+ Currently it has its own refcounting and flags.
+
+ http://cgit.freedesktop.org/~wtay/gstreamer/log/?h=miniobject2
+
+
+* GVariant registry
+
+ - allow for mmaped registy (tpm)
+
+* Incremental caps
+
+ - Remove array from caps ?
+ - make caps iterator or is the array the cache for iterator ?
+
+ We need to perform less caps operations when negotiating formats. One way is
+ to only handle small caps objects incrementally.
+
+ http://cgit.freedesktop.org/~ensonic/gstreamer/log/?h=lazycaps
+
+
+* Make GstBufferMetadata
+
+ - Make functions to register metadata
+ - Make common metadata: timeinfo, memory data, video data
+ - Remove GstBuffer Fields
+ - Make methods to add metadata to buffers.
+
+ More flexible metadata for buffers.
+
+ http://cgit.freedesktop.org/~wtay/gstreamer/log/?h=buffermeta
+
+
+* Negotiation of metadata
+
+ - figure out if we need to negotiate the metadata on the caps or if we can
+ gracefully degrade when an element doesn't understand the metadata.
+
+ We need to avoid that elements put metadata on buffers that is essential in
+ handling the buffer contents but that is then not understood by other
+ elements.
+
+
+* Rework reverse negotiation
+
+ - upstream event to notify of a downstream caps change
+ - _alloc_buffer() takes input GstBuffer prototype (or NULL)
+ - _alloc_buffer() never returns changed caps.
+
+ One of the performance problems in 0.10 is that transform elements need to
+ call gst_pad_alloc_buffer() downstream to check if the caps changed. This
+ usually also results in a useless memory allocation.
+
+ We would make a new upstream event to notify downstream elements that new caps
+ are possible somewhere downstream.
+
+ gst_pad_alloc_buffer() would take a GstBuffer as an input argument to make the
+ API easier, we can then use metadata to specify additional contraints for the
+ new buffer (such as strides, etc)
+
+
+* Incremental event progation
+
+ - certain events would be sticky on a pad like for caps
+ - rules for pushing an event downstream
+ - right before pushing a buffer
+ - after link operation
+ - activate for most serialized downstream events
+
+ This would allow an application to have more control over the state of the
+ dataflow in a pipeline.
+
+
+* GstSegment changes
+
+ - remove segment accumulation
+ - add accumulated time to the event
+ - apply segment info to pads
+ - add method on pads to get/adjust sync offset
+ - add method on pads to query current running_time
+
+ The goal is to make the timing model more comprehensible and thus make dynamic
+ pipeline plugging easier.
+
--- /dev/null
+The 0.11 porting guide
+----------------------
+
+* All deprecated methods were removed. Recompile against 0.10 with
+ DISABLE_DEPRECATED and fix issues before attempting to port to 0.11.
+
+* GST_BOILERPLATE is gone, use G_DEFINE_TYPE instead.
+
+* various methods take a gsize instead of a guint when talking about memory
+ sizes.
+
+* multifdsink, tcpclientsink, tcpclientsrc, tcpserversrc the protocol property
+ is removed, use gdppay and gdpdepay.
+
+* Presets and plugins moved to $XDG_DATA_HOME/gstreamer-0.11/ root
+ directory. Registry moved to $XDG_CACHE_HOME/gstreamer-0.11/.
+ XDG_CACHE_HOME usually points to $HOME/.cache and XDG_DATA_HOME
+ usually is $HOME/.local/share/.
+
+* GstObject:
+ GST_OBJECT_DISPOSING flag removed
+ GST_OBJECT_IS_DISPOSING removed
+ GST_OBJECT_FLOATING flag remove, GstObject is now GInitiallyUnowned
+ GST_OBJECT_IS_FLOATING removed, use g_object_is_floating()
+
+ GST_CLASS_GET_LOCK, GST_CLASS_LOCK, GST_CLASS_TRYLOCK, GST_CLASS_UNLOCK,
+ used to be a workaround for thread-unsafe glib < 2.8
+
+ gst_object_ref_sink() has gpointer as result to make it more like the
+ GObject version.
+
+ gst_object_sink() removed, use gst_object_ref_sink() instead.
+
+ gst_class_signal_connect() removed, was only used for XML
+
+ parent-set and parent-unset signals removed. Use notify:parent. Currently
+ still disabled because of deep notify locking issues.
+
+* GstElement:
+ GstElementDetails is removed and replaced with more generic metadata.
+
+ gst_element_class_set_details_simple() -> gst_element_class_set_metadata()
+ gst_element_class_set_documentation_uri -> gst_element_class_add_metadata
+ gst_element_class_set_icon_name -> gst_element_class_add_metadata
+ also gst_element_class_get_metadata()
+
+ gst_element_factory_get_longname -> gst_element_factory_get_metadata
+ gst_element_factory_get_klass -> gst_element_factory_get_metadata
+ gst_element_factory_get_description -> gst_element_factory_get_metadata
+ gst_element_factory_get_author -> gst_element_factory_get_metadata
+ gst_element_factory_get_documentation_uri -> gst_element_factory_get_metadata
+ gst_element_factory_get_icon_name -> gst_element_factory_get_metadata
+
+ gstelementmetadata.h contains the keys for all standard metadata.
+
+ gst_element_factory_can_{src,sink}_caps() => gst_element_factory_can_{src,sink}_{any,all}_caps()
+
+ Element metadata and pad templates are inherited from parent classes and
+ should be added in class_init instead of base_init.
+
+ gst_element_class_add_pad_template() takes ownership of the template
+
+ Elements that change the duration must post DURATION messages on the
+ bus when the duration changes in PAUSED or PLAYING.
+
+ gst_element_lost_state_full() -> gst_element_lost_state()
+ gst_element_lost_state() -> gst_element_lost_state(, TRUE)
+
+ request_new_pad_full() -> request_new_pad()
+
+ gst_element_found_tags() and gst_element_found_tags_for_pad() are gone, just
+ push the tag event.
+
+* GstPad:
+ gst_pad_get_caps() was replaced by gst_pad_query_caps(), it
+ does not return writable caps anymore and an explicit
+ gst_caps_make_writable() needs to be performed. This was the functionality
+ of gst_pad_get_caps_reffed(), which is removed now.
+
+ A similar change was done for gst_pad_peer_get_caps() and
+ gst_pad_peer_get_caps_reffed()
+
+ gst_pad_set_bufferalloc_function(), gst_pad_alloc_buffer() and
+ gst_pad_alloc_buffer_and_set_caps() are removed. Use the ALLOCATION query
+ now when negotiating formats to obtain a reference to a bufferpool object
+ that can be used to allocate buffers using gst_buffer_pool_acquire_buffer().
+
+ removed sched_private, it should not be used, use g_object_set_qdata() or
+ use element_private.
+
+ Removed GST_PAD_CAPS() use gst_pad_get_current_caps() to get a handle to the
+ currently configured caps.
+
+ GstPadGetCapsFunction, gst_pad_get_caps(), gst_pad_peer_get_caps(),
+ gst_pad_proxy_getcaps() now takes a GstCaps* parameter to inform
+ the other side about the possible caps and preferences.
+
+ gst_pad_get_pad_template_caps() and gst_pad_get_pad_template()
+ return a new reference of the caps or template now and the return
+ value needs to be unreffed after usage.
+
+ gst_pad_set_caps() now pushes a CAPS event for backward compatibility.
+ Consider sending the CAPS event yourself. It is not possible anymore to set
+ NULL caps.
+
+ gst_pad_set_checkgetrange_function() and gst_pad_check_pull_range() are
+ gone, use the SCHEDULING query now.
+
+ gst_pad_set_blocked(), gst_pad_set_blocked_async(),
+ gst_pad_set_blocked_async_full() are removed, use the gst_pad_add_probe()
+ method with the GST_PAD_PROBE_TYPE_BLOCK to get the same result as the async
+ blocking version. There is no more sync version of blocking, this is in
+ general dangerous and can be implemented using the callbacks if needed.
+
+ gst_pad_add_data_probe(), gst_pad_add_data_probe_full(),
+ gst_pad_remove_data_probe(), gst_pad_add_event_probe(),
+ gst_pad_add_event_probe_full(), gst_pad_remove_event_probe(),
+ gst_pad_add_buffer_probe(), gst_pad_add_buffer_probe_full(),
+ gst_pad_remove_buffer_probe() are removed. Use gst_pad_add_probe() and
+ gst_pad_remove_probe() for equivalent functionality.
+
+ The have-data signal was removed from pads, it was never supposed to be used
+ without calling the _add_.*_probe() methods.
+
+ The request-link signal was removed. It was never used.
+
+ gst_pad_get_negotiated_caps() -> get_pad_get_current_caps()
+
+ GST_FLOW_UNEXPECTED -> GST_FLOW_EOS
+
+ GstActivateMode -> GstPadMode, GST_ACTIVATE_* -> GST_PAD_MODE_*
+
+ The GstPadAcceptCapsFunction was removed and replaced with a
+ GST_QUERY_ACCEPT_CAPS query.
+
+ The GstPadFixateCapsFunction was removed. It has no replacement, you can
+ simply do the fixation in the element or use a vmethod from the base class
+ if appropriate.
+
+ The GstPadGetCapsFunction was removed and replaced with a GST_QUERY_CAPS
+ query.
+
+ gst_pad_proxy_getcaps() -> gst_pad_proxy_query_caps()
+ gst_pad_get_caps() -> gst_pad_query_caps()
+ gst_pad_peer_get_caps() -> gst_pad_peer_query_caps()
+ gst_pad_accept_caps() -> gst_pad_query_accept_caps()
+ gst_pad_peer_accept_caps() -> gst_pad_peer_query_accept_caps()
+ gst_pad_query_peer_*() -> gst_pad_peer_query_*()
+
+ GstPadFlags: GST_PAD_* -> GST_PAD_FLAG_*
+
+* GstPadTemplate
+ gst_pad_template_get_caps() returns a new reference of the caps
+ and the return value needs to be unreffed after usage.
+
+ gst_pad_template_new() does not take ownership of the caps anymore.
+
+ GstPadTemplate is now created with a floating ref and
+ gst_element_class_add_pad_template() takes ownership of this floating ref.
+
+ GstPadTemplate instances are considered immutable and must not be
+ changed.
+
+* GstMiniObject
+ A miniobject is now a simple refcounted structure holding the information
+ common to buffers, events, messages, queries and caps.
+
+ There is no more GST_TYPE_MINIOBJECT as the type for subclasses.
+ G_TYPE_BOXED can be used as the type of all GstMiniObject based types such
+ as buffers, events, messages, caps, etc. Signals, for example, would use the
+ boxed type if the argument include GstMiniObject derived types.
+
+ gst_mini_object_new() is removed. You would allocate memory with the the
+ methods specific for the derived type.
+
+ GstParamSpecMiniObject is removed, use boxed param spec now with the GType
+ of the specific GstMiniObject derived type. Also
+ gst_param_spec_mini_object().
+
+ gst_param_spec_mini_object() -> g_param_spec_boxed()
+
+ The specific gst_value_*_mini_object() methods are removed, used the generic
+ boxed methods instead.
+
+ gst_value_set_mini_object() -> g_value_set_boxed()
+ gst_value_take_mini_object() -> g_value_take_boxed()
+ gst_value_take_get_object() -> g_value_get_boxed()
+ gst_value_take_dup_object() -> g_value_dup_boxed()
+
+ GST_VALUE_HOLDS_MINI_OBJECT() was removed, use G_VALUE_HOLDS_BOXED() or
+ type-specific GST_VALUE_HOLDS_{BUFFER,CAPS,etc.}() instead.
+
+ The GST_MINI_OBJECT_READONLY flag was removed as it used to mark the
+ memory in buffers as READONLY. Marking memory READONLY can now be done
+ with the GstMemory API. Writability of miniobjects is now only done by using
+ the refcount.
+
+* GstBuffer
+ A GstBuffer is now a simple boxed type this means that subclassing is not
+ possible anymore.
+
+ To add data to the buffer you would now use gst_buffer_take_memory() with
+ a GstMemory object containing the data. Multiple memory blocks can added to
+ a GstBuffer that can then be retrieved with gst_buffer_peek_memory().
+
+ GST_BUFFER_DATA(), GST_BUFFER_MALLOCDATA(), GST_BUFFER_FREE_FUNC() and
+ GST_BUFFER_SIZE() are gone, along with the fields in GstBuffer. Use the
+ memory API to get access to the buffer data. GST_BUFFER_SIZE() can be
+ replaced with gst_buffer_get_size() but if also access to the data is
+ required, gst_buffer_map() can return both the size and data in one go.
+
+ The most common way to access all the data in a buffer is by using
+ gst_buffer_map() and gst_buffer_unmap(). These calls require you to specify
+ the access mode required to the data and will automatically merge and return
+ a writable copy of the data.
+
+ The buffer must be writable (gst_buffer_is_writable()) in order to modify
+ the fields, metadata or buffer memory. gst_buffer_make_writable() will not
+ automatically make a writable copy of the memory but will instead increase
+ the refcount of the memory. The _map() and _peek_memory() methods will
+ automatically create writable copies when needed.
+
+ gst_buffer_make_metadata_writable() is gone, you can replace this safely
+ with gst_buffer_make_writable().
+
+ gst_buffer_copy_metadata() is gone, use gst_buffer_copy_into() instead and
+ mind use GST_BUFFER_COPY_METADATA instead of the former GST_BUFFER_COPY_ALL.
+
+ gst_buffer_create_sub() is gone and can be safely replaced with
+ gst_buffer_copy_region().
+
+ Changing the size of the buffer data can be done with gst_buffer_resize(),
+ which will also update the metadata fields correctly. gst_buffer_set_size()
+ is #defined to a special case of gst_buffer_resize() with a 0 offset.
+
+ gst_buffer_try_new_and_alloc() is replaced with gst_buffer_new_and_alloc(),
+ which now returns NULL when memory allocation fails.
+
+ GST_BUFFER_CAPS() is gone, caps are not set on buffers anymore but are set
+ on the pads where the buffer is pushed on. Likewise GST_BUFFER_COPY_CAPS is
+ not needed anymore. gst_buffer_get/set_caps() are gone too.
+
+ GST_BUFFER_TIMESTAMP is gone, use GST_BUFFER_PTS or GST_BUFFER_DTS instead.
+ Likewise GST_BUFFER_TIMESTAMP_IS_VALID() was changed to
+ GST_BUFFER_PTS_IS_VALID and GST_BUFFER_DTS_IS_VALID
+
+* GstBufferList
+ The GstBufferList object is much simplified because most of the
+ functionality in the groups is now part of the GstMemory in buffers.
+
+ The object is reduced to encapsulating an array of buffers that you can send
+ with the regular gst_pad_push_list. The iterator is not needed anymore
+ because you can simply use gst_buffer_list_length() and gst_buffer_list_get()
+ to iterate the array.
+
+ For dealing with the groups, it's now needed to add the memory blocks to
+ GstBuffer and use the normal buffer API to get and merge the groups.
+
+ gst_buffer_list_sized_new() -> gst_buffer_list_new_sized()
+ gst_buffer_list_len() -> gst_buffer_list_length()
+
+* GstStructure
+
+ The GArray of the structure fields are moved to private part and are not
+ accessible from the application anymore. Use the methods to retrieve and
+ modify fields from the array.
+
+ gst_structure_empty_new() -> gst_structure_new_empty()
+ gst_structure_id_empty_new() -> gst_structure_new_id_empty()
+ gst_structure_id_new() -> gst_structure_new_id()
+
+* GstEvent
+ Boxed types derived from GstMiniObject.
+
+ GST_EVENT_SRC is removed. Don't use this anymore.
+
+ gst_event_new_qos_full() -> gst_event_new_qos()
+ gst_event_parse_qos_full() -> gst_event_parse_qos()
+
+ The GstStructure is removed from the public API, use the getters to get
+ a handle to a GstStructure.
+
+ GST_EVENT_NEWSEGMENT -> GST_EVENT_SEGMENT
+
+ gst_event_new_new_segment () -> gst_event_new_segment() and it takes a
+ GstSegment structure as an argument.
+ gst_event_parse_new_segment() -> gst_event_parse_segment() to retrieve the
+ GstSegment structure from the event.
+ gst_event_copy_segment() to fill a GstSegment structure.
+
+* GstQuery
+ Boxed types derived from GstMiniObject.
+
+ The GstStructure is removed from the public API, use the getters to get
+ a handle to a GstStructure.
+
+ gst_query_new_application() -> gst_query_new_custom()
+
+ gst_query_parse_formats_length() -> gst_query_parse_n_formats()
+ gst_query_parse_formats_nth() -> gst_query_parse_nth_format()
+
+ Some query utility functions no longer use an inout parameter for the
+ destination/query format:
+
+ - gst_pad_query_position()
+ - gst_pad_query_duration()
+ - gst_pad_query_convert()
+ - gst_pad_query_peer_position()
+ - gst_pad_query_peer_duration()
+ - gst_pad_query_peer_convert()
+ - gst_element_query_position()
+ - gst_element_query_duration()
+ - gst_element_query_convert()
+
+ gst_element_get_query_types() and gst_pad_get_query_types() with associated
+ functions were removed.
+
+* GstBufferList
+ Is now a boxed type derived from GstMiniObject.
+
+* GstMessage
+ Is now a boxed type derived from GstMiniObject
+
+ The GstStructure is removed from the public API, use the getters to get
+ a handle to a GstStructure.
+
+* GstCaps
+ Is now a boxed type derived from GstMiniObject.
+
+ GST_VIDEO_CAPS_xxx -> GST_VIDEO_CAPS_MAKE(xxx)
+
+* GstSegment
+ abs_rate was removed from the public fields, it can be trivially calculated
+ from the rate field.
+
+ accum was renamed to base. last_stop was renamed to position.
+
+ The segment info now contains all the information needed to convert buffer
+ timestamps to running_time and stream_time. There is no more segment
+ accumulation, the GstSegment is completely self contained.
+
+ gst_segment_set_duration() and gst_segment_set_last_stop() are removed,
+ simply modify the structure members duration and position respectively.
+
+ gst_segment_set_newsegment() is removed, it was used to accumulate segments
+ and is not needed anymore, use gst_segment_copy_into() or modify the segment
+ values directly.
+
+ gst_segment_set_seek() -> gst_segment_do_seek(). Updates the segment values
+ with seek parameters.
+
+* GstPluginFeature
+ GST_PLUGIN_FEATURE_NAME() was removed, use GST_OBJECT_NAME() instead.
+
+* GstTypeFind
+ gst_type_find_peek() returns a const guint8 * now.
+
+* GstTask
+ gst_task_create() -> gst_task_new()
+
+* GstAdapter
+ gst_adapter_peek() is removed, use gst_adapter_map() and gst_adapter_unmap()
+ to get access to raw data from the adapter.
+
+ Arguments changed from guint to gsize.
+
+ gst_adapter_prev_timestamp() is removed and should be replaced with
+ gst_adapter_prev_pts() and gst_adapter_prev_dts().
+
+* GstBitReader, GstByteReader, GstByteWriter
+ gst_*_reader_new_from_buffer(), gst_*_reader_init_from_buffer() removed, get
+ access to the buffer data with _map() and then use the _new() functions.
+
+ gst_byte_reader_new_from_buffer() and gst_byte_reader_init_from_buffer()
+ removed, get access to the buffer data and then use the _new() functions.
+
+* GstCollectPads
+ gst_collect_pads_read() removed, use _read_buffer() or _take_buffer() and
+ then use the memory API to get to the memory.
+
+* GstBaseSrc, GstBaseTransform, GstBaseSink
+ GstBaseSrc::get_caps(), GstBaseTransform::transform_caps() and
+ GstBaseSink::get_caps() now take a filter GstCaps* parameter to
+ filter the caps and allow better negotiation decisions.
+
+* GstBaseTransform
+ GstBaseTransform::transform_caps() now gets the complete caps passed
+ instead of getting it passed structure by structure.
+
+ GstBaseTransform::event() was renamed to sink_event(). The old function
+ uses the return value to determine if the event should be forwarded or not.
+ The new function has a default implementation that always forwards the event
+ and the return value is simply returned as a result from the event handler.
+ The semantics of the sink_event are thus the same as those for the src_event
+ function.
+
+* GstImplementsInterface
+ has been removed. Interfaces need to be updated to either have
+ is_ready/usable/available() methods, or have GError arguments
+ to their methods so we can return an appropriate error if a
+ particular interface isn't supported for a particular device.
+
+* GstIterator
+ uses a GValue based API now that is similar to the 0.10 API but
+ allows bindings to properly use GstIterator and prevents complex
+ return value ownership issues.
+
+* GstURIHandler
+ gst_uri_handler_get_uri() and the get_uri vfunc now return a copy of
+ the URI string
+
+ gst_uri_handler_set_uri() and the set_uri vfunc now take an additional
+ GError argument so the handler can notify the caller why it didn't
+ accept a particular URI.
+
+ gst_uri_handler_set_uri() now checks if the protocol of the URI passed
+ is one of the protocols advertised by the uri handler, so set_uri vfunc
+ implementations no longer need to check that as well.
+
+* GstTagList
+ is now an opaque object instead of being typedefed to a GstStructure. Cast
+ to GstStructure or use gst_structure_* API on it at your own peril (it may
+ still work for now, but might be changed in future).
+
+ gst_tag_list_new() has been renamed to gst_tag_list_new_empty().
+ gst_tag_list_new_full*() have been renamed to gst_tag_list_new*().
+
+* GstController:
+ has now been merged into GstObject. It does not exists as a individual
+ object anymore. In addition core contains a GstControlSource base class and
+ the GstControlBinding. The actual control sources are in the controller
+ library as before. The 2nd big change is that control sources generate
+ a sequence of gdouble values and those are mapped to the property type and
+ value range by GstControlBindings.
+
+ For plugins the effect is that gst_controller_init() is gone and
+ gst_object_sync_values() is taking a GstObject * instead of GObject *.
+
+ For applications the effect is larger. The whole gst_controller_* API is
+ gone and now available in simplified form under gst_object_*. ControlSources
+ are now attached via GstControlBinding to properties. There are no GValue
+ arguments used anymore when programming control sources.
+
+ gst_controller_new* -> gst_object_set_control_source
+ gst_controller_add_properties -> gst_object_set_control_source
+ gst_controller_set_control_source -> gst_object_set_control_source
+ gst_controller_get_control_source -> gst_object_get_control_source
+
+ gst_controller_set_property_disabled -> gst_object_set_controlled_property_disabled
+
+ gst_object_get_value_arrays has been removed. Loop over the controlled
+ properties fetch the value array. Also GstValueArray is gone. The fields of
+ GstValueArray are now passed directly to gst_object_get_value_array as
+ arguments.
+
+ GstInterpolationControlSource has been split. There is a new
+ GstTimedValueControlSource baseclass and 2 sub classes:
+ GstInterpolationControlSource and GstTriggerControlSource. The API for setting
+ and getting the timestamps is in GstTimedValueControlSource.
+
+ gst_interpolation_control_source_set_interpolation_mode() has been removed.
+ Set the "mode" gobject property on the control-source instead. The possible
+ enum values have been renamed from GST_INTERPOLATE_XXX to
+ GST_INTERPOLATION_MODE_XXX.
+
+* GstRegistry
+
+ gst_registry_get_default() -> gst_registry_get()
+ gst_default_registry_*(...) -> gst_registry_*(gst_registry_get(), ...)
+
+* GstValue
+
+ GST_TYPE_DATE -> G_TYPE_DATE
+ GST_VALUE_HOLDS_DATE(value) -> G_VALUE_HOLDS(value,G_TYPE_DATE)
+ gst_value_set_date() -> g_value_set_boxed()
+ gst_value_get_date() -> g_value_get_boxed()
+
+* GError/GstGError
+
+ GstGError -> GError
+ GST_TYPE_G_ERROR / gst_g_error_get_type() -> G_TYPE_ERROR

+0.11 status 1 jun 2011
+----------------------
+
+Hello again GStreamer hackers,
+
+
+Here's another status update from the 0.11 branch. This one is packed
+with new stuff because it really took too long between the last
+update, but well..
+
+
+Misc Core Changes
+-----------------
+
+The first set of big core change was done by über hacker Sebastian Dröge.
+He removed our special GST_BOILERPLATE macro. Because of some API strangeness
+we needed to do actions in the base_init method, which the GST_BOILERPLATE
+macro set up for us. The base_init concept is unfortunately not supported
+by almost all language bindings so we wanted to clean this up and use the
+regular G_DEFINE_TYPE macros. By inheriting metadata and pad templates
+from the parent, the GST_BOILERPLATE macro could be removed.
+
+
+Removal of gst_pad_alloc_buffer
+-------------------------------
+
+The next big change was the removal of gst_pad_alloc_buffer along with
+all the pad_alloc functions. The pad_alloc function were used to both
+implement allocation of buffers and notify upstream elements of new media
+formats. The functionality is replace by 3 new things: GstBufferPool (as
+noted in the previous status update), a new ALLOCATION query and a new
+RECONFIGURE event.
+
+The ALLOCATION query is used to query the downstream elements about the
+buffer properties they would like. These properties include the size,
+prefix and alignment of the memory. The downstream element can also propose
+a GstBufferPool. It is then the upstream element that decides how it
+will allocate buffers. This allows us, for example, to make the video
+decoders specify their required memory alignment to the videosink.
+
+Since new format suggestions are no longer piggybacked upstream with the
+allocation, something new was needed to notify upstream elements of a
+format change. It started with bringing in the new RENEGOTIATE event
+that Thiago Santos had been experimenting with in the 0.10 branch. The
+new event basically lets upstream elements know that new formats are
+possible somewhere downstream and it would make them renegotiate a new
+format before pushing a new buffer.
+
+New format changes can also happen when new elements are linked, so
+gst_pad_link() will also send this RENEGOTIATE event upstream. As it turns
+out, adding new elements could also signal the availability of a new
+bufferpool or different ALLOCATION properties. The RENEGOTIATE event was
+thus renamed to the more generic RECONFIGURE event.
+
+The most impressive result of these changes is that most of the
+complicated code in GstBaseTransform could simply be removed.
+
+
+Sticky Events
+-------------
+
+The idea for the sticky events comes from the observation that a lot of the
+serialized downstream events (SEGMENT, EOS, TAGS, ..) are really context
+for the buffers that follow. The design called for making these events
+sticky on the pads, meaning that they become a property of the pads
+they travel over.
+
+The result is that the current timing information (SEGMENT event) or the
+current stream medatadata (TAG event) that is handled by the pad are
+directly accessible by looking at the last event that traveled on the pad.
+
+By making the events stick on the pads, we can propagate them downstream
+automatically when new pads are linked. This should solve one of the
+biggest 0.10 problems when dealing with dynamic pipelines, the loss of
+events (mostly NEWSEGMENT events).
+
+It was then only natural to also make the CAPS event a sticky downstream
+serialized event. CAPS are indeed also context for the buffers that follow.
+The caps property was also removed from GstBuffer, making caps negotiation
+separate from the buffer dataflow again.
+
+
+GstSegment changes
+------------------
+
+For the sticky events to work with SEGMENT events, we needed to change
+the SEGMENT event so that it became selfcontained. The complicated segment
+accumulation logic of 0.10 was simply removed and replaced with pad offsets.
+
+It is now possible to tweak the timing of the data comming from a pad by
+using the pad offset property.
+
+
+GstCaps optimizations
+---------------------
+
+It doesn't look like we'll be able to implement GstCaps iterators to 0.11 so
+Sebastian was looking for other ways to improve caps performance. One of the
+low hanging fruits was to pass the complete GstCaps structure to the
+GstBaseTransform transform_caps method. This allows for better and smarter
+implementations of the function at the cost of marginally more complex code.
+
+Sebastian also added a filter caps parameter to the gst_pad_get_caps()
+function. This allows the caller to pass preferences and possible caps to
+the function. The result is that the pad can make much better negotiation
+decisions.
+
+Sebastian also optimized gst_caps_is_subset()in the 0.10 branch and ported
+the results to 0.11 as well.
+
+with the still planned caps simplifications later, these changes should
+substantially improve caps negotiation speed.
+
+
+Pad probes
+----------
+
+Quite a few iterations were needed to reimplement the pad blocking and pad
+probes. The new infrastructure allows you to add callbacks for the various
+stages in the data transfer on a pad.
+
+It's now possible to be notified when no data is going over a pad with the
+IDLE probe. This should also fix one of the big problems with implementing
+dynamic pipelines and the old pad blocking.
+
+Not all features that we want to add to the new probes are implemented yet
+but they can be added later without much trouble.
+
+
+Other gems
+----------
+
+A new SCHEDULING query was added to get more information about the upstream
+elements scheduling properties.
+
+Tim-Philipp Müller finally removed our dependency on libxml2. Back in the
+day, we used XML for serialization of objects and the registry. Object
+serialization had long been deprecated and the XML registry was replaced
+with a much faster binary registry.
+
+Tim also removed the unversioned gst-launch, gst-inspect and gst-typefind
+scripts. They were always confusing and annoying for packagers and users,
+it is just easier
+
+Edward Hervey spent some time keeping the unit tests working and making
+sure the API docs are up to data.
+
+GstIterator was made more binding friendly By Johan Dahlin and Sebastian.
+
+
+And what about the plugins..
+----------------------------
+
+As usual, all -base plugins are kept in sync with the core API updates and
+the new features. They are always a good place to see how the new API can
+be used and how to port things.
+
+
+What's next
+-----------
+
+Almost all of the features laid out in the GStreamer conference last year
+are now implemented. We also have quite a few new cool features that
+slipped in. Things are shaping up indeed.
+
+The last big missing piece is the redesign of the caps fields for raw audio
+and video. We plan to finish that in the next weeks.
+
+There are also a few smaller things we would like to do: use GstQuery
+for the various caps functions, do GstFlowReturn for the query/event
+functions, ...
+
+Meanwhile we start the stabilization phase and we will do a first prerelease
+of 0.11 this week to bring things to a wider audience. Now is the time to
+catch up and start porting your plugins to 0.11.
+
+There is still a lot of work to be done to port plugins to 0.11 before we
+can release 1.0. I ask everyone again (and especially maintainers) to help
+us porting plugins, it's really a lot of work!
+
+
+Have a nice hacking week,
+
+Wim
+
+

+ * with a given width, height and bits per plane.
* <example>
* <title>Creating a buffer for a video frame</title>
* <programlisting>
* GstBuffer *buffer;
+ * GstMemory *memory;
* gint size, width, height, bpp;
* ...
* size = width * height * bpp;
* buffer = gst_buffer_new ();
- * GST_BUFFER_SIZE (buffer) = size;
- * GST_BUFFER_MALLOCDATA (buffer) = g_malloc (size);
- * GST_BUFFER_DATA (buffer) = GST_BUFFER_MALLOCDATA (buffer);
+ * memory = gst_allocator_alloc (NULL, size, 0);
+ * gst_buffer_take_memory (buffer, -1, memory);
* ...
* </programlisting>
* </example>
*
- * Alternatively, use gst_buffer_new_and_alloc()
+ * Alternatively, use gst_buffer_new_allocate()
* to create a buffer with preallocated data of a given size.
*
- * The data pointed to by the buffer can be retrieved with the GST_BUFFER_DATA()
- * macro. The size of the data can be found with GST_BUFFER_SIZE(). For buffers
- * of size 0, the data pointer is undefined (usually NULL) and should never be used.
+ * Buffers can contain a list of #GstMemory objects. You can retrieve how many
+ * memory objects with gst_buffer_n_memory() and you can get a pointer
+ * to memory with gst_buffer_peek_memory()
*
- * If an element knows what pad you will push the buffer out on, it should use
- * gst_pad_alloc_buffer() instead to create a buffer. This allows downstream
- * elements to provide special buffers to write in, like hardware buffers.
- *
- * A buffer has a pointer to a #GstCaps describing the media type of the data
- * in the buffer. Attach caps to the buffer with gst_buffer_set_caps(); this
- * is typically done before pushing out a buffer using gst_pad_push() so that
- * the downstream element knows the type of the buffer.
- *
- * A buffer will usually have a timestamp, and a duration, but neither of these
+ * A buffer will usually have timestamps, and a duration, but neither of these
* are guaranteed (they may be set to #GST_CLOCK_TIME_NONE). Whenever a
- * meaningful value can be given for these, they should be set. The timestamp
+ * meaningful value can be given for these, they should be set. The timestamps
* and duration are measured in nanoseconds (they are #GstClockTime values).
*
* A buffer can also have one or both of a start and an end offset. These are
* next element.
*
* To efficiently create a smaller buffer out of an existing one, you can
- * use gst_buffer_create_sub().
+ * use gst_buffer_copy_region().
*
- * If a plug-in wants to modify the buffer data in-place, it should first obtain
- * a buffer that is safe to modify by using gst_buffer_make_writable(). This
- * function is optimized so that a copy will only be made when it is necessary.
- *
- * A plugin that only wishes to modify the metadata of a buffer, such as the
- * offset, timestamp or caps, should use gst_buffer_make_metadata_writable(),
- * which will create a subbuffer of the original buffer to ensure the caller
- * has sole ownership, and not copy the buffer data.
+ * If a plug-in wants to modify the buffer data or metadata in-place, it should
+ * first obtain a buffer that is safe to modify by using
+ * gst_buffer_make_writable(). This function is optimized so that a copy will
+ * only be made when it is necessary.
*
* Several flags of the buffer can be set and unset with the
* GST_BUFFER_FLAG_SET() and GST_BUFFER_FLAG_UNSET() macros. Use
* GST_BUFFER_FLAG_IS_SET() to test if a certain #GstBufferFlag is set.
*
* Buffers can be efficiently merged into a larger buffer with
- * gst_buffer_merge() and gst_buffer_span() if the gst_buffer_is_span_fast()
+ * gst_buffer_span(), which avoids memory copies when the gst_buffer_is_span_fast()
* function returns TRUE.
*
* An element should either unref the buffer or push it out on a src pad
* using gst_pad_push() (see #GstPad).
*
* Buffers are usually freed by unreffing them with gst_buffer_unref(). When
- * the refcount drops to 0, any data pointed to by GST_BUFFER_MALLOCDATA() will
- * also be freed.
+ * the refcount drops to 0, any data pointed to by the buffer is unreffed as
+ * well.

*
- * Buffer lists are units of grouped scatter/gather data transfer in
- * GStreamer.
+ * Buffer lists are an object containing a list of buffers.
*
* Buffer lists are created with gst_buffer_list_new() and filled with data
- * using a #GstBufferListIterator. The iterator has no current buffer; its
- * cursor position lies between buffers, immediately before the buffer that
- * would be returned by gst_buffer_list_iterator_next(). After iterating to the
- * end of a group the iterator must be advanced to the next group by a call to
- * gst_buffer_list_iterator_next_group() before any further calls to
- * gst_buffer_list_iterator_next() can return buffers again. The cursor position
- * of a newly created iterator lies before the first group; a call to
- * gst_buffer_list_iterator_next_group() is necessary before calls to
- * gst_buffer_list_iterator_next() can return buffers.
+ * using a gst_buffer_list_insert().

- *
- * The gst_buffer_list_iterator_remove(), gst_buffer_list_iterator_steal(),
- * gst_buffer_list_iterator_take() and gst_buffer_list_iterator_do() functions
- * are not defined in terms of the cursor position; they operate on the last
- * element returned from gst_buffer_list_iterator_next().
- *
- * The basic use pattern of creating a buffer list with an iterator is as
- * follows:
- *
- * <example>
- * <title>Creating a buffer list</title>
- * <programlisting>
- * GstBufferList *list;
- * GstBufferListIterator *it;
- *
- * list = gst_buffer_list_new ();
- * it = gst_buffer_list_iterate (list);
- * gst_buffer_list_iterator_add_group (it);
- * gst_buffer_list_iterator_add (it, header1);
- * gst_buffer_list_iterator_add (it, data1);
- * gst_buffer_list_iterator_add_group (it);
- * gst_buffer_list_iterator_add (it, header2);
- * gst_buffer_list_iterator_add (it, data2);
- * gst_buffer_list_iterator_add_group (it);
- * gst_buffer_list_iterator_add (it, header3);
- * gst_buffer_list_iterator_add (it, data3);
- * ...
- * gst_buffer_list_iterator_free (it);
- * </programlisting>
- * </example>
- *
- * The basic use pattern of iterating over a buffer list is as follows:
- *
- * <example>
- * <title>Iterating a buffer list</title>
- * <programlisting>
- * GstBufferListIterator *it;
- *
- * it = gst_buffer_list_iterate (list);
- * while (gst_buffer_list_iterator_next_group (it)) {
- * while ((buffer = gst_buffer_list_iterator_next (it)) != NULL) {
- * do_something_with_buffer (buffer);
- * }
- * }
- * gst_buffer_list_iterator_free (it);
- * </programlisting>
- * </example>
- *
- * The basic use pattern of modifying a buffer in a list is as follows:
- *
- * <example>
- * <title>Modifying the data of the first buffer in a list</title>
- * <programlisting>
- * GstBufferListIterator *it;
- *
- * list = gst_buffer_list_make_writable (list);
- * it = gst_buffer_list_iterate (list);
- * if (gst_buffer_list_iterator_next_group (it)) {

- * @GST_SEEK_FLAG_KEY_UNIT: seek to the nearest keyframe. This might be
- * faster but less accurate.
- * @GST_SEEK_FLAG_SEGMENT: perform a segment seek.
- * @GST_SEEK_FLAG_SKIP: when doing fast foward or fast reverse playback, allow
- * elements to skip frames instead of generating all
- * frames. Since 0.10.22.
- *
- * Flags to be used with gst_element_seek() or gst_event_new_seek(). All flags
- * can be used together.
- *
- * A non flushing seek might take some time to perform as the currently
- * playing data in the pipeline will not be cleared.
- *
- * An accurate seek might be slower for formats that don't have any indexes
- * or timestamp markers in the stream. Specifying this flag might require a
- * complete scan of the file in those cases.
- *
- * When performing a segment seek: after the playback of the segment completes,
- * no EOS will be emmited by the element that performed the seek, but a
- * #GST_MESSAGE_SEGMENT_DONE message will be posted on the bus by the element.
- * When this message is posted, it is possible to send a new seek event to
- * continue playback. With this seek method it is possible to perform seamless
- * looping or simple linear editing.
- *
- * When doing fast forward (rate > 1.0) or fast reverse (rate < -1.0) trickmode
- * playback, the @GST_SEEK_FLAG_SKIP flag can be used to instruct decoders
- * and demuxers to adjust the playback rate by skipping frames. This can improve
- * performance and decrease CPU usage because not all frames need to be decoded.
- *
- * Also see part-seeking.txt in the GStreamer design documentation for more
- * details on the meaning of these flags and the behaviour expected of
- * elements that handle them.
+ * gst_event_take:
+ * @old_event: (inout) (transfer full): pointer to a pointer to a #GstEvent
+ * to be stolen.
+ * @new_event: (allow-none) (transfer full): pointer to a #GstEvent that will
+ * replace the event pointed to by @old_event.
+ *
+ * Modifies a pointer to a #GstEvent to point to a different #GstEvent. This
+ * function is similar to gst_event_replace() except that it takes ownership of
+ * @new_event.
+ *
+ * Either @new_event or the #GstEvent pointed to by @old_event may be NULL.
+ *
+ * Returns: TRUE if @new_event was different from @old_event

+ * SECTION:gstmemory
+ * @short_description: refcounted wrapper for memory blocks
+ * @see_also: #GstBuffer
+ *
+ * GstMemory is a lightweight refcounted object that wraps a region of memory.
+ * They are typically used to manage the data of a #GstBuffer.
+ *
+ * A GstMemory object has an allocated region of memory of maxsize. The maximum
+ * size does not change during the lifetime of the memory object. The memory
+ * also has an offset and size property that specifies the valid range of memory
+ * in the allocated region.
+ *
+ * Memory is usually created by allocators with a gst_allocator_alloc()
+ * method call. When NULL is used as the allocator, the default allocator will
+ * be used.
+ *
+ * New allocators can be registered with gst_allocator_register().
+ * Allocators are identified by name and can be retrieved with
+ * gst_allocator_find().
+ *
+ * New memory can be created with gst_memory_new_wrapped() that wraps the memory
+ * allocated elsewhere.
+ *
+ * Refcounting of the memory block is performed with gst_memory_ref() and
+ * gst_memory_unref().
+ *
+ * The size of the memory can be retrieved and changed with
+ * gst_memory_get_sizes() and gst_memory_resize() respectively.
+ *
+ * Getting access to the data of the memory is performed with gst_memory_map().
+ * The call will return a pointer to offset bytes into the region of memory.
+ * After the memory access is completed, gst_memory_unmap() should be called.
+ *
+ * Memory can be copied with gst_memory_copy(), which will returnn a writable
+ * copy. gst_memory_share() will create a new memory block that shares the
+ * memory with an existing memory block at a custom offset and with a custom
+ * size.
+ *
+ * Memory can be efficiently merged when gst_memory_is_span() returns TRUE.
+ *

- * the caps when you no longer need it. This function returns NULL when
- * the @pad has no peer or is not negotiated yet.
+ * Invokes the default query handler for the given pad.
+ * The query is sent to all pads internally linked to @pad. Note that

* @event: (transfer full): the #GstEvent to send to the pad.
*
- * Sends the event to the pad. This function can be used

- *
- * If @pad is a source pad, @event should be an upstream event. If @pad is a

- * Furthermore, some downstream events have to be serialized with data flow,
- * like EOS, while some can travel out-of-band, like #GST_EVENT_FLUSH_START. If
- * the event needs to be serialized with data flow, this function will take the
- * pad's stream lock while calling its event function.
- *
- * To find out whether an event type is upstream, downstream, or downstream and
- * serialized, see #GstEventTypeFlags, gst_event_type_get_flags(),
- * #GST_EVENT_IS_UPSTREAM, #GST_EVENT_IS_DOWNSTREAM, and
- * #GST_EVENT_IS_SERIALIZED. Note that in practice that an application or
- * plugin doesn't need to bother itself with this information; the core handles
- * all necessary locks and checks.
+ * Sends the event to the peer of the given pad. This function is
+ * mainly used by elements to send events to their peer
+ * elements.
*
* This function takes owership of the provided event so you should
* gst_event_ref() it if you want to reuse the event after this call.
*
* Returns: TRUE if the event was handled.

+ *
+ * When doing fast forward (rate > 1.0) or fast reverse (rate < -1.0) trickmode
+ * playback, the @GST_SEEK_FLAG_SKIP flag can be used to instruct decoders
+ * and demuxers to adjust the playback rate by skipping frames. This can improve
+ * performance and decrease CPU usage because not all frames need to be decoded.

- *
- * Deprecated: This feature is deprecated pipeline serialization to XML is

-%package -n gstreamer-tools
-Summary: common tools and files for GStreamer streaming media framework
-Group: Applications/Multimedia
-
-%description -n gstreamer-tools
-GStreamer is a streaming media framework, based on graphs of filters which
-operate on media data. Applications using this library can do anything
-from real-time sound processing to playing videos, and just about anything
-else media-related. Its plugin-based architecture means that new data
-types or processing capabilities can be added simply by installing new
-plugins.
-
-This package contains wrapper scripts for the command-line tools that work
-with different major/minor versions of GStreamer.

*
* The theory of operation is like this: All buffers received are put
* into the adapter using gst_adapter_push() and the data is then read back
- * in chunks of the desired size using gst_adapter_peek(). After the data is
- * processed, it is freed using gst_adapter_flush().
+ * in chunks of the desired size using gst_adapter_map()/gst_adapter_unmap()
+ * and/or gst_adapter_copy(). After the data has been processed, it is freed
+ * using gst_adapter_unmap().
*
* Other methods such as gst_adapter_take() and gst_adapter_take_buffer()
- * combine gst_adapter_peek() and gst_adapter_flush() in one method and are
+ * combine gst_adapter_map() and gst_adapter_unmap() in one method and are
* potentially more convenient for some use cases.
*
* For example, a sink pad's chain function that needs to pass data to a library
* gst_adapter_push (adapter, buffer);
* // while we can read out 512 bytes, process them
* while (gst_adapter_available (adapter) >= 512 && ret == GST_FLOW_OK) {
+ * const guint8 *data = gst_adapter_map (adapter, 512);
* // use flowreturn as an error value
- * ret = my_library_foo (gst_adapter_peek (adapter, 512));
+ * ret = my_library_foo (data);
+ * gst_adapter_unmap (adapter);
* gst_adapter_flush (adapter, 512);
* }

- * however, this function will use the specified function @func to obtain the
- * data needed by the typefind functions, rather than operating on a given
- * source pad. This is useful mostly for elements like tag demuxers which
- * strip off data at the beginning and/or end of a file and want to typefind
- * the stripped data stream before adding their own source pad (the specified
- * callback can then call the upstream peer pad with offsets adjusted for the
- * tag size, for example).
- *
- * Free-function: gst_caps_unref
- *
- * Returns: (transfer full): the #GstCaps corresponding to the data stream.
- * Returns #NULL if no #GstCaps matches the data stream.

- * @short_description: dynamic parameter control subsystem
- *
- * The controller subsystem offers a lightweight way to adjust gobject
- * properties over stream-time. It works by using time-stamped value pairs that
- * are queued for element-properties. At run-time the elements continously pull
- * values changes for the current stream-time.
- *
- * What needs to be changed in a #GstElement?
- * Very little - it is just two steps to make a plugin controllable!
- * <orderedlist>
- * <listitem><para>
- * mark gobject-properties paramspecs that make sense to be controlled,
- * by GST_PARAM_CONTROLLABLE.
- * </para></listitem>
- * <listitem><para>
- * when processing data (get, chain, loop function) at the beginning call
- * gst_object_sync_values(element,timestamp).
- * This will made the controller to update all gobject properties that are under
- * control with the current values based on timestamp.
- * </para></listitem>
- * </orderedlist>
- *
- * What needs to be done in applications?
- * Again its not a lot to change.
- * <orderedlist>
- * <listitem><para>
- * first put some properties under control, by calling
- * controller = gst_object_control_properties (object, "prop1", "prop2",...);
- * </para></listitem>
- * <listitem><para>
- * create a #GstControlSource.
- * csource = gst_interpolation_control_source_new ();
- * gst_interpolation_control_source_set_interpolation_mode(csource, mode);
- * </para></listitem>
- * <listitem><para>
- * Attach the #GstControlSource on the controller to a property.
- * gst_controller_set_control_source (controller, "prop1", csource);
- * </para></listitem>
- * <listitem><para>
- * Set the control values
- * gst_interpolation_control_source_set (csource,0 * GST_SECOND, value1);

-/**
- * SECTION:gstdataprotocol
- * @short_description: Serialization of caps, buffers and events.
- * @see_also: #GstCaps, #GstEvent, #GstBuffer
- *
- * This helper library provides serialization of GstBuffer, GstCaps and
- * GstEvent structures.
- *
- * This serialization is useful when GStreamer needs to interface with
- * the outside world to transport data between distinct GStreamer pipelines.
- * The connections with the outside world generally don't have mechanisms
- * to transport properties of these structures.
- *
- * For example, transporting buffers across named pipes or network connections
- * doesn't maintain the buffer size and separation.
- *
- * This data protocol assumes a reliable connection-oriented transport, such as
- * TCP, a pipe, or a file. The protocol does not serialize the caps for
- * each buffer; instead, it transport the caps only when they change in the
- * stream. This implies that there will always be a caps packet before any
- * buffer packets.
- *
- * The versioning of the protocol is independent of GStreamer's version.
- * The major number gets incremented, and the minor reset, for incompatible
- * changes. The minor number gets incremented for compatible changes that
- * allow clients who do not completely understand the newer protocol version
- * to still decode what they do understand.
- *
- * Version 0.2 serializes only a small subset of all events, with a custom
- * payload for each type. Also, all GDP streams start with the initial caps
- * packet.
- *
- * Version 1.0 serializes all events by taking the string representation of
- * the event as the payload. In addition, GDP streams can now start with
- * events as well, as required by the new data stream model in GStreamer 0.10.
- *
- * Converting buffers, caps and events to GDP buffers is done using a
- * #GstDPPacketizer object and invoking its packetizer functions.
- * For backwards-compatibility reasons, the old 0.2 methods are still
- * available but deprecated.
- *
- * For reference, this image shows the byte layout of the GDP header:
- *
- * <inlinegraphic format="PNG" fileref="gdp-header.png"></inlinegraphic>

-/**********************************************************************
- * GStreamer Default File Source
- * Theory of Operation
- *
- * Update: see GstFileSrc:use-mmap property documentation below
- * for why use of mmap() is disabled by default.
- *
- * This source uses mmap(2) to efficiently load data from a file.
- * To do this without seriously polluting the applications' memory
- * space, it must do so in smaller chunks, say 1-4MB at a time.
- * Buffers are then subdivided from these mmap'd chunks, to directly
- * make use of the mmap.
- *
- * To handle refcounting so that the mmap can be freed at the appropriate
- * time, a buffer will be created for each mmap'd region, and all new
- * buffers will be sub-buffers of this top-level buffer. As they are
- * freed, the refcount goes down on the mmap'd buffer and its free()
- * function is called, which will call munmap(2) on itself.
- *
- * If a buffer happens to cross the boundaries of an mmap'd region, we
- * have to decide whether it's more efficient to copy the data into a
- * new buffer, or mmap() just that buffer. There will have to be a
- * breakpoint size to determine which will be done. The mmap() size
- * has a lot to do with this as well, because you end up in double-
- * jeopardy: the larger the outgoing buffer, the more data to copy when
- * it overlaps, *and* the more frequently you'll have buffers that *do*
- * overlap.
- *
- * Seeking is another tricky aspect to do efficiently. The initial
- * implementation of this source won't make use of these features, however.
- * The issue is that if an application seeks backwards in a file, *and*
- * that region of the file is covered by an mmap that hasn't been fully
- * deallocated, we really should re-use it. But keeping track of these
- * regions is tricky because we have to lock the structure that holds
- * them. We need to settle on a locking primitive (GMutex seems to be
- * a really good option...), then we can do that.

- * @start_time: running time at which to start the new segment, or -1 to
- * use the running time of the newly active sink pad
- *
- * Switch to a new feed. The segment opened by the previously active pad, if
- * any, will be closed, and a new segment opened before data flows again.
- *
- * This signal must be emitted when the element has been blocked via the <link
- * linkend="GstInputSelector-block">block</link> signal.
- *
- * If you have a stream with only one switch element, such as an audio-only
- * stream, a stream switch should be performed by first emitting the block
- * signal, and then emitting the switch signal with -1 for the stop and start
- * time values.
- *
- * The intention of the @stop_time and @start_time arguments is to allow
- * multiple switch elements to switch and maintain stream synchronization.
- * When switching a stream with multiple feeds, you will need as many switch
- * elements as you have feeds. For example, a feed with audio and video will
- * have one switch element between the audio feeds and one for video.
- *
- * A switch over multiple switch elements should be performed as follows:
- * First, emit the <link linkend="GstInputSelector-block">block</link>
- * signal, collecting the returned values. The maximum running time returned
- * by block should then be used as the time at which to close the previous
- * segment.
- *
- * Then, query the running times of the new audio and video pads that you will
- * switch to. Naturally, these pads are on separate switch elements. Take the
- * minimum running time for those streams and use it for the time at which to
- * open the new segment.
- *
- * If @pad is the same as the current active pad, the element will cancel any
- * previous block without adjusting segments.
- *
- * <note><simpara>
- * the signal changed from accepting the pad name to the pad object.

-gst-launch
-================
-
-This is a tool that will construct pipelines based on a command-line
-syntax. The syntax is rather complex to enable all the features I want it
-to have, but should be easy to use for most people. Multi-pathed and
-feedback pipelines are the most complex.
-
-A simple commandline looks like:
-
- gst-launch filesrc location=music.mp3 ! mad ! osssink
-
-This plays an mp3 music file music.mp3 using libmad, and:
-
- gst-launch filesrc location=music.mp3 ! mp3parse ! mpg123 ! osssink
-
-Plays and mp3 music file using mpg123
-
-You can also stream files over http:
-
- gst-launch httpsrc location=http://domain.com/music.mp3 ! mad ! osssink
-
-And using gnome-vfs you can do the same with:
-
- gst-launch gnomevfssrc location=music.mp3 ! mad ! osssink
- gst-launch gnomevfssrc location=http://domain.com/music.mp3 ! mad ! osssink
-
-And too play the same song with gnome-vfs via smb:
-
- gst-launch gnomevfssrc location=smb://computer/music.mp3 ! mad ! osssink
-
-Here we convert a Mp3 file into an Ogg Vorbis file:
-
- gst-launch filesrc location=music.mp3 ! mad ! vorbisenc ! filesink location=music.ogg
-
-And then we can play that file with:
-
- gst-launch filesrc location=music.ogg ! oggdemux ! vorbisdec ! audioconvert ! osssink
-
-Some other useful pipelines are..
-Plays wav files (currently there are no wav encoders):
-
- gst-launch filesrc location=music.wav ! wavparse ! osssink
-
-Converts wav files into mp3 and ogg files:
-
- gst-launch filesrc location=music.wav ! wavparse ! vorbisenc ! filesink location=music.ogg
- gst-launch filesrc location=music.wav ! wavparse ! mpegaudio ! filesink location=music.mp3
-
-You can also use lame for mp3 encoding if you have it installed, it does a
-much better job than mpegaudio.
-
-Rips all songs from cd and saves them into a mp3 file:
-
- gst-launch cdparanoia ! mpegaudio ! filesink location=cd.mp3
-
-You can toy around with gst-inspect to discover the settings for
-cdparanoia to rip individual tracks
-
-Record sound from your sound input and encode it into an ogg file:
-
- gst-launch osssrc ! vorbisenc ! filesink location=input.ogg
-
-gst-launch not only handles audio but video as well:
-For mpeg1 files (video and audio streams respectively):
-
- gst-launch filesrc location=video.mpg ! mpegdemux video_00! { queue ! mpeg2dec ! sdlvideosink }
- gst-launch filesrc location=video.mpg ! mpegdemux audio_00! { queue ! mad ! osssink }
-
-for mpeg1 with both audio and video (for glib2):
-
- gst-launch filesrc location=video.mpg ! mpegdemux name=demux video_00! { queue ! mpeg2dec ! sdlvideosink } demux.audio_00! { queue ! mad ! osssink }
-
-for mpeg1 with both audio and video (for gtk1.2, the shim doesn't handle the 'name' property yet):
-
- gst-launch filesrc location=video.mpg ! mpegdemux video_00! { queue ! mpeg2dec ! sdlvideosink } mpegdemux0.audio_00! { queue ! mad ! osssink }
-
-For mpeg2 files (video and audio streams respectively):
-
- gst-launch filesrc location=video.mpeg ! mpegdemux video_00! { queue ! mpeg2dec ! sdlvideosink }
- gst-launch filesrc location=video.mpeg ! mpegdemux private_stream_1.0! { queue ! a52dec ! osssink }
-
-for mpeg2 with both audio and video (glib2):
-
- gst-launch filesrc location=video.mpg ! mpegdemux name=demux video_00! { queue ! mpeg2dec ! sdlvideosink } demux.private_stream_1.0! { queue ! a52dec ! osssink }
-
-Note: The types of audio streams in the mpeg files can vary!
-
-For an avi file (DivX, mjpeg,...)
-
- gst-launch filesrc location=video.avi ! avidecoder video_00! { queue ! sdlvideosink } avidecoder0.audio_00! { queue ! osssink }
-
-
-
-gst-complete
-==================
-
-This is a simple utility which provides custom bash completion when
-typing gst-launch commands.
-
-Simply run "gst-compprep" as root to build the registry of completions,
-and then put, in your .bashrc,
-"complete -C gst-complete gst-launch"
-(ensuring that gst-complete is on your path).
-
-You can then enjoy context sensitive tab-completion of gst-launch
-commands.
-
-
-
-gst-inspect
-=================
-
-Allows you to check the properties of plugins and elements.
-
- ./gst-inspect
-
-will show all the plugins available and the elements they contain.
-
- ./gst-inspect <pluginname/elementname>
-
-shows more info about the plugin/element.
-
-
-
-gst-xmlinspect
-=================
-
-Dump properties of plugins and elements in an xml format. You can
-transform the xml to something else with an appropriate stylesheet.
-
- ./gst-xmlinspect <elementname> | xsltproc xml2text.xsl -

-.TH GStreamer 1 "June 2002"
-.SH "NAME"
-gst\-feedback - generate debug info for GStreamer bug reports
-.SH "SYNOPSIS"
-.B gst-feedback
-.SH "DESCRIPTION"
-.PP
-\fIgst\-feedback\fP is a utility that scans the system for various
-information that is useful to GStreamer developers to help diagnose
-user problem.
-.PP
-Depending on the type of bug report, it may be useful to attach the
-output of \fIgst\-feedback\fP when you contact the developers.
-.PP
-NOTE: The current version of this script scans many dirs:
-/usr/lib /usr/local/lib /home /usr/include /usr/local/include /home (again)
-for various GStreamer installations. Depending on your system you may not
-want to do this. Improvements to the script are welcome.
-.SH "USAGE"
-Generate the feedback information by running \fIgst\-feedback\fP:
-.TP 8
-.B gst\-feedback
-.TP -8
-Possibly redirect output and errors to a file:
-.TP 8
-.B gst\-feedback &> myfeedback
-.SH "WARNING"
-The \fIgst\-feedback\fP dumps a lot of information about a system, some
-of which may be considered sensitive. If this is a concern, review the
-information before posting to a public forum, such as the GStreamer bug
-tracking system.

-.TH "GStreamer" "1" "March 2001"
-.SH "NAME"
-gst\-xmllaunch \- build and run a GStreamer pipeline from an XML serialization
-.SH "SYNOPSIS"
-\fBgst\-xmllaunch\fR \fI[OPTION...]\fR XML\-FILE [ ELEMENT.PROPERTY=VALUE ... ]
-.SH "DESCRIPTION"
-.LP
-\fIgst\-xmllaunch\fP is a tool that is used to build and run a basic
-\fIGStreamer\fP pipeline, loading it from an XML description. You can
-produce the XML description using gst-launch(1) with the -o option or by
-calling gst_xml_write_file() in your own app.
-
-A simple commandline looks like:
-
- gst\-xmllaunch my\-pipeline.xml filesrc0.location=music.mp3
-
-This sets the location property of the element named filesrc0 to the value
-"music.mp3". See gst\-launch(1) for syntax on setting element names, and
-gst\-inspect to see what properties various elements have.
-
-You can pass "-" as the XML\-FILE to read from stdin.
-
-XML\-FILE can be a URI as well, thanks to the wizardry of libxml. I'm not really
-sure what all is supported, it seems http works just fine though.
-
-.
-.SH "WARNING"
-\fIgst\-xmllaunch\fP is deprecated and broken for all but the most simple
-pipelines. It will most likely be removed in future. Don't use it.
-.
-.SH "OPTIONS"
-.l
-\fIgst\-xmllaunch\fP accepts the following options:
-.TP 8
-.B \-\-help
-Print help synopsis and available FLAGS
-.TP 8
-.B \-\-silent
-Do not output status information
-.TP 8
-.B \-\-exclude=TYPE, \-XTYPE
-Do not output status information of TYPE
-.TP 8
-.B \-\-output=FILE, \-oFILE
-Save XML representation of pipeline to FILE and exit
-.TP 8
-.B \-\-gst\-info\-mask=FLAGS
-\fIGStreamer\fP info flags to set (list with \-\-help)
-.TP 8
-.B \-\-gst\-debug\-mask=FLAGS
-\fIGStreamer\fP debugging flags to set (list with \-\-help)
-.TP 8
-.B \-\-gst\-mask=FLAGS
-\fIGStreamer\fP info and debugging flags to set (list with \-\-help)
-.TP 8
-.B \-\-gst\-plugin\-spew
-\fIGStreamer\fP info flags to set
-Enable printout of errors while loading \fIGStreamer\fP plugins
-.TP 8
-.B \-\-gst\-plugin\-path=PATH
-Add directories separated with ':' to the plugin search path
