4 * All deprecated methods were removed. Recompile against 0.10 with
5 DISABLE_DEPRECATED and fix issues before attempting to port to 0.11.
7 * GST_BOILERPLATE is gone, use G_DEFINE_TYPE instead.
9 * various methods take a gsize instead of a guint when talking about memory
12 * multifdsink, tcpclientsink, tcpclientsrc, tcpserversrc the protocol property
13 is removed, use gdppay and gdpdepay.
15 * Presets and plugins moved to $XDG_DATA_HOME/gstreamer-0.11/ root
16 directory. Registry moved to $XDG_CACHE_HOME/gstreamer-0.11/.
17 XDG_CACHE_HOME usually points to $HOME/.cache and XDG_DATA_HOME
18 usually is $HOME/.local/share/.
21 GST_OBJECT_DISPOSING flag removed
22 GST_OBJECT_IS_DISPOSING removed
23 GST_OBJECT_FLOATING flag remove, GstObject is now GInitiallyUnowned
24 GST_OBJECT_IS_FLOATING removed, use g_object_is_floating()
26 GST_CLASS_GET_LOCK, GST_CLASS_LOCK, GST_CLASS_TRYLOCK, GST_CLASS_UNLOCK,
27 used to be a workaround for thread-unsafe glib < 2.8
29 gst_object_ref_sink() has gpointer as result to make it more like the
32 gst_object_sink() removed, use gst_object_ref_sink() instead.
34 gst_class_signal_connect() removed, was only used for XML
36 parent-set and parent-unset signals removed. Use notify:parent. Currently
37 still disabled because of deep notify locking issues.
40 GstElementDetails is removed and replaced with more generic metadata.
42 gst_element_class_set_details_simple() -> gst_element_class_set_metadata()
43 gst_element_class_set_documentation_uri -> gst_element_class_add_metadata
44 gst_element_class_set_icon_name -> gst_element_class_add_metadata
45 also gst_element_class_get_metadata()
47 gst_element_factory_get_longname -> gst_element_factory_get_metadata
48 gst_element_factory_get_klass -> gst_element_factory_get_metadata
49 gst_element_factory_get_description -> gst_element_factory_get_metadata
50 gst_element_factory_get_author -> gst_element_factory_get_metadata
51 gst_element_factory_get_documentation_uri -> gst_element_factory_get_metadata
52 gst_element_factory_get_icon_name -> gst_element_factory_get_metadata
54 gstelementmetadata.h contains the keys for all standard metadata.
56 gst_element_factory_can_{src,sink}_caps() => gst_element_factory_can_{src,sink}_{any,all}_caps()
58 Element metadata and pad templates are inherited from parent classes and
59 should be added in class_init instead of base_init.
61 gst_element_class_add_pad_template() takes ownership of the template
63 gst_element_class_add_static_pad_template (element_class, &src_template)
64 => gst_element_class_add_pad_template (element_class,
65 gst_static_pad_template_get (&src_template));
67 Elements that change the duration must post DURATION messages on the
68 bus when the duration changes in PAUSED or PLAYING.
70 gst_element_lost_state_full() -> gst_element_lost_state()
71 gst_element_lost_state() -> gst_element_lost_state(, TRUE)
73 request_new_pad_full() -> request_new_pad()
75 gst_element_found_tags() and gst_element_found_tags_for_pad() are gone, just
79 gst_pad_get_caps() was replaced by gst_pad_query_caps(), it
80 does not return writable caps anymore and an explicit
81 gst_caps_make_writable() needs to be performed. This was the functionality
82 of gst_pad_get_caps_reffed(), which is removed now.
84 A similar change was done for gst_pad_peer_get_caps() and
85 gst_pad_peer_get_caps_reffed()
87 gst_pad_set_bufferalloc_function(), gst_pad_alloc_buffer() and
88 gst_pad_alloc_buffer_and_set_caps() are removed. Use the ALLOCATION query
89 now when negotiating formats to obtain a reference to a bufferpool object
90 that can be used to allocate buffers using gst_buffer_pool_acquire_buffer().
92 removed sched_private, it should not be used, use g_object_set_qdata() or
95 Removed GST_PAD_CAPS() use gst_pad_get_current_caps() to get a handle to the
96 currently configured caps.
98 gst_pad_get_pad_template_caps() and gst_pad_get_pad_template()
99 return a new reference of the caps or template now and the return
100 value needs to be unreffed after usage.
102 gst_pad_set_caps() now pushes a CAPS event for backward compatibility.
103 Consider sending the CAPS event yourself. It is not possible anymore to set
106 gst_pad_set_checkgetrange_function() and gst_pad_check_pull_range() are
107 gone, use the SCHEDULING query now.
109 gst_pad_set_blocked(), gst_pad_set_blocked_async(),
110 gst_pad_set_blocked_async_full() are removed, use the gst_pad_add_probe()
111 method with the GST_PAD_PROBE_TYPE_BLOCK to get the same result as the async
112 blocking version. There is no more sync version of blocking, this is in
113 general dangerous and can be implemented using the callbacks if needed.
115 gst_pad_add_data_probe(), gst_pad_add_data_probe_full(),
116 gst_pad_remove_data_probe(), gst_pad_add_event_probe(),
117 gst_pad_add_event_probe_full(), gst_pad_remove_event_probe(),
118 gst_pad_add_buffer_probe(), gst_pad_add_buffer_probe_full(),
119 gst_pad_remove_buffer_probe() are removed. Use gst_pad_add_probe() and
120 gst_pad_remove_probe() for equivalent functionality.
122 The have-data signal was removed from pads, it was never supposed to be used
123 without calling the _add_.*_probe() methods.
125 The request-link signal was removed. It was never used.
127 gst_pad_get_negotiated_caps() -> get_pad_get_current_caps()
129 GST_FLOW_UNEXPECTED -> GST_FLOW_EOS
131 GstActivateMode -> GstPadMode, GST_ACTIVATE_* -> GST_PAD_MODE_*
133 The GstPadAcceptCapsFunction was removed and replaced with a
134 GST_QUERY_ACCEPT_CAPS query.
136 The GstPadFixateCapsFunction was removed. It has no replacement, you can
137 simply do the fixation in the element or use a vmethod from the base class
140 The GstPadGetCapsFunction was removed and replaced with a GST_QUERY_CAPS
141 query. The query takes a GstCaps* parameter to inform the other side about
142 the possible caps and preferences.
144 gst_pad_proxy_getcaps() -> gst_pad_proxy_query_caps()
145 gst_pad_get_caps() -> gst_pad_query_caps()
146 gst_pad_peer_get_caps() -> gst_pad_peer_query_caps()
147 gst_pad_accept_caps() -> gst_pad_query_accept_caps()
148 gst_pad_peer_accept_caps() -> gst_pad_peer_query_accept_caps()
149 gst_pad_query_peer_*() -> gst_pad_peer_query_*()
151 GstPadFlags: GST_PAD_* -> GST_PAD_FLAG_*
154 gst_pad_template_get_caps() returns a new reference of the caps
155 and the return value needs to be unreffed after usage.
157 gst_pad_template_new() does not take ownership of the caps anymore.
159 GstPadTemplate is now created with a floating ref and
160 gst_element_class_add_pad_template() takes ownership of this floating ref.
162 GstPadTemplate instances are considered immutable and must not be
166 A miniobject is now a simple refcounted structure holding the information
167 common to buffers, events, messages, queries and caps.
169 There is no more GST_TYPE_MINIOBJECT as the type for subclasses.
170 G_TYPE_BOXED can be used as the type of all GstMiniObject based types such
171 as buffers, events, messages, caps, etc. Signals, for example, would use the
172 boxed type if the argument include GstMiniObject derived types.
174 gst_mini_object_new() is removed. You would allocate memory with the the
175 methods specific for the derived type.
177 GstParamSpecMiniObject is removed, use boxed param spec now with the GType
178 of the specific GstMiniObject derived type. Also
179 gst_param_spec_mini_object().
181 gst_param_spec_mini_object() -> g_param_spec_boxed()
183 The specific gst_value_*_mini_object() methods are removed, used the generic
184 boxed methods instead.
186 gst_value_set_mini_object() -> g_value_set_boxed()
187 gst_value_take_mini_object() -> g_value_take_boxed()
188 gst_value_take_get_object() -> g_value_get_boxed()
189 gst_value_take_dup_object() -> g_value_dup_boxed()
191 GST_VALUE_HOLDS_MINI_OBJECT() was removed, use G_VALUE_HOLDS_BOXED() or
192 type-specific GST_VALUE_HOLDS_{BUFFER,CAPS,etc.}() instead.
194 The GST_MINI_OBJECT_READONLY flag was removed as it used to mark the
195 memory in buffers as READONLY. Marking memory READONLY can now be done
196 with the GstMemory API. Writability of miniobjects is now only done by using
200 A GstBuffer is now a simple boxed type this means that subclassing is not
203 To add data to the buffer you would now use gst_buffer_insert_memory() with
204 a GstMemory object containing the data. Multiple memory blocks can added to
205 a GstBuffer that can then be retrieved with gst_buffer_peek_memory().
207 GST_BUFFER_DATA(), GST_BUFFER_MALLOCDATA(), GST_BUFFER_FREE_FUNC() and
208 GST_BUFFER_SIZE() are gone, along with the fields in GstBuffer. Use the
209 memory API to get access to the buffer data. GST_BUFFER_SIZE() can be
210 replaced with gst_buffer_get_size() but if also access to the data is
211 required, gst_buffer_map() can return both the size and data in one go.
213 The most common way to access all the data in a buffer is by using
214 gst_buffer_map() and gst_buffer_unmap(). These calls require you to specify
215 the access mode required to the data and will automatically merge and return
216 a writable copy of the data.
218 The buffer must be writable (gst_buffer_is_writable()) in order to modify
219 the fields, metadata or buffer memory. gst_buffer_make_writable() will not
220 automatically make a writable copy of the memory but will instead increase
221 the refcount of the memory. The _map() and _peek_memory() methods will
222 automatically create writable copies when needed.
224 gst_buffer_make_metadata_writable() is gone, you can replace this safely
225 with gst_buffer_make_writable().
227 gst_buffer_copy_metadata() is gone, use gst_buffer_copy_into() instead and
228 mind use GST_BUFFER_COPY_METADATA instead of the former GST_BUFFER_COPY_ALL.
230 gst_buffer_create_sub() is gone and can be safely replaced with
231 gst_buffer_copy_region().
233 Changing the size of the buffer data can be done with gst_buffer_resize(),
234 which will also update the metadata fields correctly. gst_buffer_set_size()
235 is #defined to a special case of gst_buffer_resize() with a 0 offset.
237 gst_buffer_try_new_and_alloc() is replaced with gst_buffer_new_and_alloc(),
238 which now returns NULL when memory allocation fails.
240 GST_BUFFER_CAPS() is gone, caps are not set on buffers anymore but are set
241 on the pads where the buffer is pushed on. Likewise GST_BUFFER_COPY_CAPS is
242 not needed anymore. gst_buffer_get/set_caps() are gone too.
244 GST_BUFFER_TIMESTAMP is gone, use GST_BUFFER_PTS or GST_BUFFER_DTS instead.
245 Likewise GST_BUFFER_TIMESTAMP_IS_VALID() was changed to
246 GST_BUFFER_PTS_IS_VALID and GST_BUFFER_DTS_IS_VALID
248 gst_buffer_join() was renamed to gst_buffer_append() and the memory is not
249 directly merged but appended.
251 gst_buffer_merge() was removed, it is the same as gst_buffer_join() but
252 without taking ownership of the arguments. Caller code should ref themselves
253 when needed. Note that the extra refs might force slower paths in
256 gst_buffer_is_span() and gst_buffer_span() are removed, use
257 gst_buffer_merge() and gst_buffer_resize() for the same effect. Merging and
258 spanning is delayed until the buffer is mapped and in some cases no merging
259 of memory is needed at all when the element can deal with individual memory
263 The GstBufferList object is much simplified because most of the
264 functionality in the groups is now part of the GstMemory in buffers.
266 The object is reduced to encapsulating an array of buffers that you can send
267 with the regular gst_pad_push_list. The iterator is not needed anymore
268 because you can simply use gst_buffer_list_length() and gst_buffer_list_get()
269 to iterate the array.
271 For dealing with the groups, it's now needed to add the memory blocks to
272 GstBuffer and use the normal buffer API to get and merge the groups.
274 gst_buffer_list_sized_new() -> gst_buffer_list_new_sized()
275 gst_buffer_list_len() -> gst_buffer_list_length()
279 The GArray of the structure fields are moved to private part and are not
280 accessible from the application anymore. Use the methods to retrieve and
281 modify fields from the array.
283 gst_structure_empty_new() -> gst_structure_new_empty()
284 gst_structure_id_empty_new() -> gst_structure_new_id_empty()
285 gst_structure_id_new() -> gst_structure_new_id()
288 Boxed types derived from GstMiniObject.
290 GST_EVENT_SRC is removed. Don't use this anymore.
292 gst_event_new_qos_full() -> gst_event_new_qos()
293 gst_event_parse_qos_full() -> gst_event_parse_qos()
295 The GstStructure is removed from the public API, use the getters to get
296 a handle to a GstStructure.
298 GST_EVENT_NEWSEGMENT -> GST_EVENT_SEGMENT
300 gst_event_new_new_segment () -> gst_event_new_segment() and it takes a
301 GstSegment structure as an argument.
302 gst_event_parse_new_segment() -> gst_event_parse_segment() to retrieve the
303 GstSegment structure from the event.
304 gst_event_copy_segment() to fill a GstSegment structure.
307 Boxed types derived from GstMiniObject.
309 The GstStructure is removed from the public API, use the getters to get
310 a handle to a GstStructure.
312 gst_query_new_application() -> gst_query_new_custom()
314 gst_query_parse_formats_length() -> gst_query_parse_n_formats()
315 gst_query_parse_formats_nth() -> gst_query_parse_nth_format()
317 Some query utility functions no longer use an inout parameter for the
318 destination/query format:
320 - gst_pad_query_position()
321 - gst_pad_query_duration()
322 - gst_pad_query_convert()
323 - gst_pad_query_peer_position()
324 - gst_pad_query_peer_duration()
325 - gst_pad_query_peer_convert()
326 - gst_element_query_position()
327 - gst_element_query_duration()
328 - gst_element_query_convert()
330 gst_element_get_query_types() and gst_pad_get_query_types() with associated
331 functions were removed.
334 Is now a boxed type derived from GstMiniObject.
337 Is now a boxed type derived from GstMiniObject
339 The GstStructure is removed from the public API, use the getters to get
340 a handle to a GstStructure.
343 Is now a boxed type derived from GstMiniObject.
345 GST_VIDEO_CAPS_xxx -> GST_VIDEO_CAPS_MAKE(xxx)
347 Some caps functions now take ownership of the input argument, for
348 efficiency reasons (to avoid unnecessary copies to make them writable):
350 gst_caps_normalize (caps) => caps = gst_caps_normalize (caps)
351 gst_caps_do_simplify (caps) => caps = gst_caps_simplify (caps)
352 gst_caps_merge (caps,caps2) => caps = gst_caps_merge (caps,caps2)
353 gst_caps_merge_structure (caps,st) => caps = gst_caps_merge_structure (caps,st)
354 gst_caps_truncate (caps) => caps = gst_caps_truncate (caps)
356 The compiler should warn about unused return values from these functions,
357 which may help find the places that need to be updated.
361 gst_caps_union() -> gst_caps_merge(): Be careful because _merge takes
362 ownership of the arguments.
365 gst_clock_id_wait_async_full() was renamed to gst_clock_id_wait_async() and
366 the old gst_clock_id_wait_async() function was removed.
369 abs_rate was removed from the public fields, it can be trivially calculated
372 accum was renamed to base. last_stop was renamed to position.
374 The segment info now contains all the information needed to convert buffer
375 timestamps to running_time and stream_time. There is no more segment
376 accumulation, the GstSegment is completely self contained.
378 gst_segment_set_duration() and gst_segment_set_last_stop() are removed,
379 simply modify the structure members duration and position respectively.
381 gst_segment_set_newsegment() is removed, it was used to accumulate segments
382 and is not needed anymore, use gst_segment_copy_into() or modify the segment
385 gst_segment_set_seek() -> gst_segment_do_seek(). Updates the segment values
386 with seek parameters.
389 GST_PLUGIN_FEATURE_NAME() was removed, use GST_OBJECT_NAME() instead.
392 gst_type_find_peek() returns a const guint8 * now.
395 gst_task_create() -> gst_task_new()
398 gst_adapter_peek() is removed, use gst_adapter_map() and gst_adapter_unmap()
399 to get access to raw data from the adapter.
401 Arguments changed from guint to gsize.
403 gst_adapter_prev_timestamp() is removed and should be replaced with
404 gst_adapter_prev_pts() and gst_adapter_prev_dts().
406 * GstBitReader, GstByteReader, GstByteWriter
407 gst_*_reader_new_from_buffer(), gst_*_reader_init_from_buffer() removed, get
408 access to the buffer data with _map() and then use the _new() functions.
410 gst_byte_reader_new_from_buffer() and gst_byte_reader_init_from_buffer()
411 removed, get access to the buffer data and then use the _new() functions.
414 gst_collect_pads_read() removed, use _read_buffer() or _take_buffer() and
415 then use the memory API to get to the memory.
417 * GstBaseSrc, GstBaseTransform, GstBaseSink
418 GstBaseSrc::get_caps(), GstBaseTransform::transform_caps() and
419 GstBaseSink::get_caps() now take a filter GstCaps* parameter to
420 filter the caps and allow better negotiation decisions.
423 GstBaseTransform::transform_caps() now gets the complete caps passed
424 instead of getting it passed structure by structure.
426 GstBaseTransform::event() was renamed to sink_event(). The old function
427 uses the return value to determine if the event should be forwarded or not.
428 The new function has a default implementation that always forwards the event
429 and the return value is simply returned as a result from the event handler.
430 The semantics of the sink_event are thus the same as those for the src_event
433 * GstImplementsInterface
434 has been removed. Interfaces need to be updated to either have
435 is_ready/usable/available() methods, or have GError arguments
436 to their methods so we can return an appropriate error if a
437 particular interface isn't supported for a particular device.
440 uses a GValue based API now that is similar to the 0.10 API but
441 allows bindings to properly use GstIterator and prevents complex
442 return value ownership issues.
445 gst_uri_handler_get_uri() and the get_uri vfunc now return a copy of
448 gst_uri_handler_set_uri() and the set_uri vfunc now take an additional
449 GError argument so the handler can notify the caller why it didn't
450 accept a particular URI.
452 gst_uri_handler_set_uri() now checks if the protocol of the URI passed
453 is one of the protocols advertised by the uri handler, so set_uri vfunc
454 implementations no longer need to check that as well.
457 is now an opaque mini object instead of being typedefed to a GstStructure.
459 While it was previously okay (and in some cases required because of
460 missing taglist API) to cast a GstTagList to a GstStructure or use
461 gst_structure_* API on taglists, you can no longer do that. Doing so will
464 Also, tag lists are refcounted now, and can therefore not be freely
465 modified any longer. Make sure to call
467 taglist = gst_tag_list_make_writable (taglist);
469 before adding, removing or changing tags in the taglist.
471 gst_tag_list_new() has been renamed to gst_tag_list_new_empty().
472 gst_tag_list_new_full*() have been renamed to gst_tag_list_new*().
473 gst_tag_list_free() has been replaced by gst_tag_list_unref().
476 has now been merged into GstObject. It does not exists as a individual
477 object anymore. In addition core contains a GstControlSource base class and
478 the GstControlBinding. The actual control sources are in the controller
479 library as before. The 2nd big change is that control sources generate
480 a sequence of gdouble values and those are mapped to the property type and
481 value range by GstControlBindings.
483 For plugins the effect is that gst_controller_init() is gone and
484 gst_object_sync_values() is taking a GstObject * instead of GObject *.
486 For applications the effect is larger. The whole gst_controller_* API is
487 gone and now available in simplified form under gst_object_*. ControlSources
488 are now attached via GstControlBinding to properties. There are no GValue
489 arguments used anymore when programming control sources.
491 gst_controller_new* -> gst_object_set_control_source
492 gst_controller_add_properties -> gst_object_set_control_source
493 gst_controller_set_control_source -> gst_object_set_control_source
494 gst_controller_get_control_source -> gst_object_get_control_source
496 gst_controller_set_property_disabled -> gst_object_set_controlled_property_disabled
498 gst_object_get_value_arrays has been removed. Loop over the controlled
499 properties fetch the value array. Also GstValueArray is gone. The fields of
500 GstValueArray are now passed directly to gst_object_get_value_array as
503 GstInterpolationControlSource has been split. There is a new
504 GstTimedValueControlSource baseclass and 2 sub classes:
505 GstInterpolationControlSource and GstTriggerControlSource. The API for setting
506 and getting the timestamps is in GstTimedValueControlSource.
508 gst_interpolation_control_source_set_interpolation_mode() has been removed.
509 Set the "mode" gobject property on the control-source instead. The possible
510 enum values have been renamed from GST_INTERPOLATE_XXX to
511 GST_INTERPOLATION_MODE_XXX.
515 gst_registry_get_default() -> gst_registry_get()
516 gst_default_registry_*(...) -> gst_registry_*(gst_registry_get(), ...)
520 GST_TYPE_DATE -> G_TYPE_DATE
521 GST_VALUE_HOLDS_DATE(value) -> G_VALUE_HOLDS(value,G_TYPE_DATE)
522 gst_value_set_date() -> g_value_set_boxed()
523 gst_value_get_date() -> g_value_get_boxed()
528 GST_TYPE_G_ERROR / gst_g_error_get_type() -> G_TYPE_ERROR
530 * "codec-data" and "streamheader" field in GstCaps
532 codec-data and stream headers are no longer in GstCaps, but sent as
533 part of a STREAM CONFIG event (which should be sent after the initial
534 CAPS event if needed).
