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 Elements that change the duration must post DURATION messages on the
64 bus when the duration changes in PAUSED or PLAYING.
66 gst_element_lost_state_full() -> gst_element_lost_state()
67 gst_element_lost_state() -> gst_element_lost_state(, TRUE)
69 request_new_pad_full() -> request_new_pad()
71 gst_element_found_tags() and gst_element_found_tags_for_pad() are gone, just
75 gst_pad_get_caps() was replaced by gst_pad_query_caps(), it
76 does not return writable caps anymore and an explicit
77 gst_caps_make_writable() needs to be performed. This was the functionality
78 of gst_pad_get_caps_reffed(), which is removed now.
80 A similar change was done for gst_pad_peer_get_caps() and
81 gst_pad_peer_get_caps_reffed()
83 gst_pad_set_bufferalloc_function(), gst_pad_alloc_buffer() and
84 gst_pad_alloc_buffer_and_set_caps() are removed. Use the ALLOCATION query
85 now when negotiating formats to obtain a reference to a bufferpool object
86 that can be used to allocate buffers using gst_buffer_pool_acquire_buffer().
88 removed sched_private, it should not be used, use g_object_set_qdata() or
91 Removed GST_PAD_CAPS() use gst_pad_get_current_caps() to get a handle to the
92 currently configured caps.
94 GstPadGetCapsFunction, gst_pad_get_caps(), gst_pad_peer_get_caps(),
95 gst_pad_proxy_getcaps() now takes a GstCaps* parameter to inform
96 the other side about the possible caps and preferences.
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
143 gst_pad_proxy_getcaps() -> gst_pad_proxy_query_caps()
144 gst_pad_get_caps() -> gst_pad_query_caps()
145 gst_pad_peer_get_caps() -> gst_pad_peer_query_caps()
146 gst_pad_accept_caps() -> gst_pad_query_accept_caps()
147 gst_pad_peer_accept_caps() -> gst_pad_peer_query_accept_caps()
148 gst_pad_query_peer_*() -> gst_pad_peer_query_*()
150 GstPadFlags: GST_PAD_* -> GST_PAD_FLAG_*
153 gst_pad_template_get_caps() returns a new reference of the caps
154 and the return value needs to be unreffed after usage.
156 gst_pad_template_new() does not take ownership of the caps anymore.
158 GstPadTemplate is now created with a floating ref and
159 gst_element_class_add_pad_template() takes ownership of this floating ref.
161 GstPadTemplate instances are considered immutable and must not be
165 A miniobject is now a simple refcounted structure holding the information
166 common to buffers, events, messages, queries and caps.
168 There is no more GST_TYPE_MINIOBJECT as the type for subclasses.
169 G_TYPE_BOXED can be used as the type of all GstMiniObject based types such
170 as buffers, events, messages, caps, etc. Signals, for example, would use the
171 boxed type if the argument include GstMiniObject derived types.
173 gst_mini_object_new() is removed. You would allocate memory with the the
174 methods specific for the derived type.
176 GstParamSpecMiniObject is removed, use boxed param spec now with the GType
177 of the specific GstMiniObject derived type. Also
178 gst_param_spec_mini_object().
180 gst_param_spec_mini_object() -> g_param_spec_boxed()
182 The specific gst_value_*_mini_object() methods are removed, used the generic
183 boxed methods instead.
185 gst_value_set_mini_object() -> g_value_set_boxed()
186 gst_value_take_mini_object() -> g_value_take_boxed()
187 gst_value_take_get_object() -> g_value_get_boxed()
188 gst_value_take_dup_object() -> g_value_dup_boxed()
190 GST_VALUE_HOLDS_MINI_OBJECT() was removed, use G_VALUE_HOLDS_BOXED() or
191 type-specific GST_VALUE_HOLDS_{BUFFER,CAPS,etc.}() instead.
193 The GST_MINI_OBJECT_READONLY flag was removed as it used to mark the
194 memory in buffers as READONLY. Marking memory READONLY can now be done
195 with the GstMemory API. Writability of miniobjects is now only done by using
199 A GstBuffer is now a simple boxed type this means that subclassing is not
202 To add data to the buffer you would now use gst_buffer_take_memory() with
203 a GstMemory object containing the data. Multiple memory blocks can added to
204 a GstBuffer that can then be retrieved with gst_buffer_peek_memory().
206 GST_BUFFER_DATA(), GST_BUFFER_MALLOCDATA(), GST_BUFFER_FREE_FUNC() and
207 GST_BUFFER_SIZE() are gone, along with the fields in GstBuffer. Use the
208 memory API to get access to the buffer data. GST_BUFFER_SIZE() can be
209 replaced with gst_buffer_get_size() but if also access to the data is
210 required, gst_buffer_map() can return both the size and data in one go.
212 The most common way to access all the data in a buffer is by using
213 gst_buffer_map() and gst_buffer_unmap(). These calls require you to specify
214 the access mode required to the data and will automatically merge and return
215 a writable copy of the data.
217 The buffer must be writable (gst_buffer_is_writable()) in order to modify
218 the fields, metadata or buffer memory. gst_buffer_make_writable() will not
219 automatically make a writable copy of the memory but will instead increase
220 the refcount of the memory. The _map() and _peek_memory() methods will
221 automatically create writable copies when needed.
223 gst_buffer_make_metadata_writable() is gone, you can replace this safely
224 with gst_buffer_make_writable().
226 gst_buffer_copy_metadata() is gone, use gst_buffer_copy_into() instead and
227 mind use GST_BUFFER_COPY_METADATA instead of the former GST_BUFFER_COPY_ALL.
229 gst_buffer_create_sub() is gone and can be safely replaced with
230 gst_buffer_copy_region().
232 Changing the size of the buffer data can be done with gst_buffer_resize(),
233 which will also update the metadata fields correctly. gst_buffer_set_size()
234 is #defined to a special case of gst_buffer_resize() with a 0 offset.
236 gst_buffer_try_new_and_alloc() is replaced with gst_buffer_new_and_alloc(),
237 which now returns NULL when memory allocation fails.
239 GST_BUFFER_CAPS() is gone, caps are not set on buffers anymore but are set
240 on the pads where the buffer is pushed on. Likewise GST_BUFFER_COPY_CAPS is
241 not needed anymore. gst_buffer_get/set_caps() are gone too.
243 GST_BUFFER_TIMESTAMP is gone, use GST_BUFFER_PTS or GST_BUFFER_DTS instead.
244 Likewise GST_BUFFER_TIMESTAMP_IS_VALID() was changed to
245 GST_BUFFER_PTS_IS_VALID and GST_BUFFER_DTS_IS_VALID
248 The GstBufferList object is much simplified because most of the
249 functionality in the groups is now part of the GstMemory in buffers.
251 The object is reduced to encapsulating an array of buffers that you can send
252 with the regular gst_pad_push_list. The iterator is not needed anymore
253 because you can simply use gst_buffer_list_length() and gst_buffer_list_get()
254 to iterate the array.
256 For dealing with the groups, it's now needed to add the memory blocks to
257 GstBuffer and use the normal buffer API to get and merge the groups.
259 gst_buffer_list_sized_new() -> gst_buffer_list_new_sized()
260 gst_buffer_list_len() -> gst_buffer_list_length()
264 The GArray of the structure fields are moved to private part and are not
265 accessible from the application anymore. Use the methods to retrieve and
266 modify fields from the array.
268 gst_structure_empty_new() -> gst_structure_new_empty()
269 gst_structure_id_empty_new() -> gst_structure_new_id_empty()
270 gst_structure_id_new() -> gst_structure_new_id()
273 Boxed types derived from GstMiniObject.
275 GST_EVENT_SRC is removed. Don't use this anymore.
277 gst_event_new_qos_full() -> gst_event_new_qos()
278 gst_event_parse_qos_full() -> gst_event_parse_qos()
280 The GstStructure is removed from the public API, use the getters to get
281 a handle to a GstStructure.
283 GST_EVENT_NEWSEGMENT -> GST_EVENT_SEGMENT
285 gst_event_new_new_segment () -> gst_event_new_segment() and it takes a
286 GstSegment structure as an argument.
287 gst_event_parse_new_segment() -> gst_event_parse_segment() to retrieve the
288 GstSegment structure from the event.
289 gst_event_copy_segment() to fill a GstSegment structure.
292 Boxed types derived from GstMiniObject.
294 The GstStructure is removed from the public API, use the getters to get
295 a handle to a GstStructure.
297 gst_query_new_application() -> gst_query_new_custom()
299 gst_query_parse_formats_length() -> gst_query_parse_n_formats()
300 gst_query_parse_formats_nth() -> gst_query_parse_nth_format()
302 Some query utility functions no longer use an inout parameter for the
303 destination/query format:
305 - gst_pad_query_position()
306 - gst_pad_query_duration()
307 - gst_pad_query_convert()
308 - gst_pad_query_peer_position()
309 - gst_pad_query_peer_duration()
310 - gst_pad_query_peer_convert()
311 - gst_element_query_position()
312 - gst_element_query_duration()
313 - gst_element_query_convert()
315 gst_element_get_query_types() and gst_pad_get_query_types() with associated
316 functions were removed.
319 Is now a boxed type derived from GstMiniObject.
322 Is now a boxed type derived from GstMiniObject
324 The GstStructure is removed from the public API, use the getters to get
325 a handle to a GstStructure.
328 Is now a boxed type derived from GstMiniObject.
330 GST_VIDEO_CAPS_xxx -> GST_VIDEO_CAPS_MAKE(xxx)
333 abs_rate was removed from the public fields, it can be trivially calculated
336 accum was renamed to base. last_stop was renamed to position.
338 The segment info now contains all the information needed to convert buffer
339 timestamps to running_time and stream_time. There is no more segment
340 accumulation, the GstSegment is completely self contained.
342 gst_segment_set_duration() and gst_segment_set_last_stop() are removed,
343 simply modify the structure members duration and position respectively.
345 gst_segment_set_newsegment() is removed, it was used to accumulate segments
346 and is not needed anymore, use gst_segment_copy_into() or modify the segment
349 gst_segment_set_seek() -> gst_segment_do_seek(). Updates the segment values
350 with seek parameters.
353 GST_PLUGIN_FEATURE_NAME() was removed, use GST_OBJECT_NAME() instead.
356 gst_type_find_peek() returns a const guint8 * now.
359 gst_task_create() -> gst_task_new()
362 gst_adapter_peek() is removed, use gst_adapter_map() and gst_adapter_unmap()
363 to get access to raw data from the adapter.
365 Arguments changed from guint to gsize.
367 gst_adapter_prev_timestamp() is removed and should be replaced with
368 gst_adapter_prev_pts() and gst_adapter_prev_dts().
370 * GstBitReader, GstByteReader, GstByteWriter
371 gst_*_reader_new_from_buffer(), gst_*_reader_init_from_buffer() removed, get
372 access to the buffer data with _map() and then use the _new() functions.
374 gst_byte_reader_new_from_buffer() and gst_byte_reader_init_from_buffer()
375 removed, get access to the buffer data and then use the _new() functions.
378 gst_collect_pads_read() removed, use _read_buffer() or _take_buffer() and
379 then use the memory API to get to the memory.
381 * GstBaseSrc, GstBaseTransform, GstBaseSink
382 GstBaseSrc::get_caps(), GstBaseTransform::transform_caps() and
383 GstBaseSink::get_caps() now take a filter GstCaps* parameter to
384 filter the caps and allow better negotiation decisions.
387 GstBaseTransform::transform_caps() now gets the complete caps passed
388 instead of getting it passed structure by structure.
390 GstBaseTransform::event() was renamed to sink_event(). The old function
391 uses the return value to determine if the event should be forwarded or not.
392 The new function has a default implementation that always forwards the event
393 and the return value is simply returned as a result from the event handler.
394 The semantics of the sink_event are thus the same as those for the src_event
397 * GstImplementsInterface
398 has been removed. Interfaces need to be updated to either have
399 is_ready/usable/available() methods, or have GError arguments
400 to their methods so we can return an appropriate error if a
401 particular interface isn't supported for a particular device.
404 uses a GValue based API now that is similar to the 0.10 API but
405 allows bindings to properly use GstIterator and prevents complex
406 return value ownership issues.
409 gst_uri_handler_get_uri() and the get_uri vfunc now return a copy of
412 gst_uri_handler_set_uri() and the set_uri vfunc now take an additional
413 GError argument so the handler can notify the caller why it didn't
414 accept a particular URI.
416 gst_uri_handler_set_uri() now checks if the protocol of the URI passed
417 is one of the protocols advertised by the uri handler, so set_uri vfunc
418 implementations no longer need to check that as well.
421 is now an opaque object instead of being typedefed to a GstStructure. Cast
422 to GstStructure or use gst_structure_* API on it at your own peril (it may
423 still work for now, but might be changed in future).
425 gst_tag_list_new() has been renamed to gst_tag_list_new_empty().
426 gst_tag_list_new_full*() have been renamed to gst_tag_list_new*().
429 has now been merged into GstObject. It does not exists as a individual
430 object anymore. In addition core contains a GstControlSource base class and
431 the GstControlBinding. The actual control sources are in the controller
432 library as before. The 2nd big change is that control sources generate
433 a sequence of gdouble values and those are mapped to the property type and
434 value range by GstControlBindings.
436 For plugins the effect is that gst_controller_init() is gone and
437 gst_object_sync_values() is taking a GstObject * instead of GObject *.
439 For applications the effect is larger. The whole gst_controller_* API is
440 gone and now available in simplified form under gst_object_*. ControlSources
441 are now attached via GstControlBinding to properties. There are no GValue
442 arguments used anymore when programming control sources.
444 gst_controller_new* -> gst_object_set_control_source
445 gst_controller_add_properties -> gst_object_set_control_source
446 gst_controller_set_control_source -> gst_object_set_control_source
447 gst_controller_get_control_source -> gst_object_get_control_source
449 gst_controller_set_property_disabled -> gst_object_set_controlled_property_disabled
451 gst_object_get_value_arrays has been removed. Loop over the controlled
452 properties fetch the value array. Also GstValueArray is gone. The fields of
453 GstValueArray are now passed directly to gst_object_get_value_array as
456 GstInterpolationControlSource has been split. There is a new
457 GstTimedValueControlSource baseclass and 2 sub classes:
458 GstInterpolationControlSource and GstTriggerControlSource. The API for setting
459 and getting the timestamps is in GstTimedValueControlSource.
461 gst_interpolation_control_source_set_interpolation_mode() has been removed.
462 Set the "mode" gobject property on the control-source instead. The possible
463 enum values have been renamed from GST_INTERPOLATE_XXX to
464 GST_INTERPOLATION_MODE_XXX.
468 gst_registry_get_default() -> gst_registry_get()
469 gst_default_registry_*(...) -> gst_registry_*(gst_registry_get(), ...)
473 GST_TYPE_DATE -> G_TYPE_DATE
474 GST_VALUE_HOLDS_DATE(value) -> G_VALUE_HOLDS(value,G_TYPE_DATE)
475 gst_value_set_date() -> g_value_set_boxed()
476 gst_value_get_date() -> g_value_get_boxed()
481 GST_TYPE_G_ERROR / gst_g_error_get_type() -> G_TYPE_ERROR
483 * "codec-data" and "streamheader" field in GstCaps
485 codec-data and stream headers are no longer in GstCaps, but sent as
486 part of a STREAM CONFIG event (which should be sent after the initial
487 CAPS event if needed).
