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 GstPadGetCapsFunction, gst_pad_get_caps(), gst_pad_peer_get_caps(),
99 gst_pad_proxy_getcaps() now takes a GstCaps* parameter to inform
100 the other side about the possible caps and preferences.
102 gst_pad_get_pad_template_caps() and gst_pad_get_pad_template()
103 return a new reference of the caps or template now and the return
104 value needs to be unreffed after usage.
106 gst_pad_set_caps() now pushes a CAPS event for backward compatibility.
107 Consider sending the CAPS event yourself. It is not possible anymore to set
110 gst_pad_set_checkgetrange_function() and gst_pad_check_pull_range() are
111 gone, use the SCHEDULING query now.
113 gst_pad_set_blocked(), gst_pad_set_blocked_async(),
114 gst_pad_set_blocked_async_full() are removed, use the gst_pad_add_probe()
115 method with the GST_PAD_PROBE_TYPE_BLOCK to get the same result as the async
116 blocking version. There is no more sync version of blocking, this is in
117 general dangerous and can be implemented using the callbacks if needed.
119 gst_pad_add_data_probe(), gst_pad_add_data_probe_full(),
120 gst_pad_remove_data_probe(), gst_pad_add_event_probe(),
121 gst_pad_add_event_probe_full(), gst_pad_remove_event_probe(),
122 gst_pad_add_buffer_probe(), gst_pad_add_buffer_probe_full(),
123 gst_pad_remove_buffer_probe() are removed. Use gst_pad_add_probe() and
124 gst_pad_remove_probe() for equivalent functionality.
126 The have-data signal was removed from pads, it was never supposed to be used
127 without calling the _add_.*_probe() methods.
129 The request-link signal was removed. It was never used.
131 gst_pad_get_negotiated_caps() -> get_pad_get_current_caps()
133 GST_FLOW_UNEXPECTED -> GST_FLOW_EOS
135 GstActivateMode -> GstPadMode, GST_ACTIVATE_* -> GST_PAD_MODE_*
137 The GstPadAcceptCapsFunction was removed and replaced with a
138 GST_QUERY_ACCEPT_CAPS query.
140 The GstPadFixateCapsFunction was removed. It has no replacement, you can
141 simply do the fixation in the element or use a vmethod from the base class
144 The GstPadGetCapsFunction was removed and replaced with a GST_QUERY_CAPS
147 gst_pad_proxy_getcaps() -> gst_pad_proxy_query_caps()
148 gst_pad_get_caps() -> gst_pad_query_caps()
149 gst_pad_peer_get_caps() -> gst_pad_peer_query_caps()
150 gst_pad_accept_caps() -> gst_pad_query_accept_caps()
151 gst_pad_peer_accept_caps() -> gst_pad_peer_query_accept_caps()
152 gst_pad_query_peer_*() -> gst_pad_peer_query_*()
154 GstPadFlags: GST_PAD_* -> GST_PAD_FLAG_*
157 gst_pad_template_get_caps() returns a new reference of the caps
158 and the return value needs to be unreffed after usage.
160 gst_pad_template_new() does not take ownership of the caps anymore.
162 GstPadTemplate is now created with a floating ref and
163 gst_element_class_add_pad_template() takes ownership of this floating ref.
165 GstPadTemplate instances are considered immutable and must not be
169 A miniobject is now a simple refcounted structure holding the information
170 common to buffers, events, messages, queries and caps.
172 There is no more GST_TYPE_MINIOBJECT as the type for subclasses.
173 G_TYPE_BOXED can be used as the type of all GstMiniObject based types such
174 as buffers, events, messages, caps, etc. Signals, for example, would use the
175 boxed type if the argument include GstMiniObject derived types.
177 gst_mini_object_new() is removed. You would allocate memory with the the
178 methods specific for the derived type.
180 GstParamSpecMiniObject is removed, use boxed param spec now with the GType
181 of the specific GstMiniObject derived type. Also
182 gst_param_spec_mini_object().
184 gst_param_spec_mini_object() -> g_param_spec_boxed()
186 The specific gst_value_*_mini_object() methods are removed, used the generic
187 boxed methods instead.
189 gst_value_set_mini_object() -> g_value_set_boxed()
190 gst_value_take_mini_object() -> g_value_take_boxed()
191 gst_value_take_get_object() -> g_value_get_boxed()
192 gst_value_take_dup_object() -> g_value_dup_boxed()
194 GST_VALUE_HOLDS_MINI_OBJECT() was removed, use G_VALUE_HOLDS_BOXED() or
195 type-specific GST_VALUE_HOLDS_{BUFFER,CAPS,etc.}() instead.
197 The GST_MINI_OBJECT_READONLY flag was removed as it used to mark the
198 memory in buffers as READONLY. Marking memory READONLY can now be done
199 with the GstMemory API. Writability of miniobjects is now only done by using
203 A GstBuffer is now a simple boxed type this means that subclassing is not
206 To add data to the buffer you would now use gst_buffer_take_memory() with
207 a GstMemory object containing the data. Multiple memory blocks can added to
208 a GstBuffer that can then be retrieved with gst_buffer_peek_memory().
210 GST_BUFFER_DATA(), GST_BUFFER_MALLOCDATA(), GST_BUFFER_FREE_FUNC() and
211 GST_BUFFER_SIZE() are gone, along with the fields in GstBuffer. Use the
212 memory API to get access to the buffer data. GST_BUFFER_SIZE() can be
213 replaced with gst_buffer_get_size() but if also access to the data is
214 required, gst_buffer_map() can return both the size and data in one go.
216 The most common way to access all the data in a buffer is by using
217 gst_buffer_map() and gst_buffer_unmap(). These calls require you to specify
218 the access mode required to the data and will automatically merge and return
219 a writable copy of the data.
221 The buffer must be writable (gst_buffer_is_writable()) in order to modify
222 the fields, metadata or buffer memory. gst_buffer_make_writable() will not
223 automatically make a writable copy of the memory but will instead increase
224 the refcount of the memory. The _map() and _peek_memory() methods will
225 automatically create writable copies when needed.
227 gst_buffer_make_metadata_writable() is gone, you can replace this safely
228 with gst_buffer_make_writable().
230 gst_buffer_copy_metadata() is gone, use gst_buffer_copy_into() instead and
231 mind use GST_BUFFER_COPY_METADATA instead of the former GST_BUFFER_COPY_ALL.
233 gst_buffer_create_sub() is gone and can be safely replaced with
234 gst_buffer_copy_region().
236 Changing the size of the buffer data can be done with gst_buffer_resize(),
237 which will also update the metadata fields correctly. gst_buffer_set_size()
238 is #defined to a special case of gst_buffer_resize() with a 0 offset.
240 gst_buffer_try_new_and_alloc() is replaced with gst_buffer_new_and_alloc(),
241 which now returns NULL when memory allocation fails.
243 GST_BUFFER_CAPS() is gone, caps are not set on buffers anymore but are set
244 on the pads where the buffer is pushed on. Likewise GST_BUFFER_COPY_CAPS is
245 not needed anymore. gst_buffer_get/set_caps() are gone too.
247 GST_BUFFER_TIMESTAMP is gone, use GST_BUFFER_PTS or GST_BUFFER_DTS instead.
248 Likewise GST_BUFFER_TIMESTAMP_IS_VALID() was changed to
249 GST_BUFFER_PTS_IS_VALID and GST_BUFFER_DTS_IS_VALID
252 The GstBufferList object is much simplified because most of the
253 functionality in the groups is now part of the GstMemory in buffers.
255 The object is reduced to encapsulating an array of buffers that you can send
256 with the regular gst_pad_push_list. The iterator is not needed anymore
257 because you can simply use gst_buffer_list_length() and gst_buffer_list_get()
258 to iterate the array.
260 For dealing with the groups, it's now needed to add the memory blocks to
261 GstBuffer and use the normal buffer API to get and merge the groups.
263 gst_buffer_list_sized_new() -> gst_buffer_list_new_sized()
264 gst_buffer_list_len() -> gst_buffer_list_length()
268 The GArray of the structure fields are moved to private part and are not
269 accessible from the application anymore. Use the methods to retrieve and
270 modify fields from the array.
272 gst_structure_empty_new() -> gst_structure_new_empty()
273 gst_structure_id_empty_new() -> gst_structure_new_id_empty()
274 gst_structure_id_new() -> gst_structure_new_id()
277 Boxed types derived from GstMiniObject.
279 GST_EVENT_SRC is removed. Don't use this anymore.
281 gst_event_new_qos_full() -> gst_event_new_qos()
282 gst_event_parse_qos_full() -> gst_event_parse_qos()
284 The GstStructure is removed from the public API, use the getters to get
285 a handle to a GstStructure.
287 GST_EVENT_NEWSEGMENT -> GST_EVENT_SEGMENT
289 gst_event_new_new_segment () -> gst_event_new_segment() and it takes a
290 GstSegment structure as an argument.
291 gst_event_parse_new_segment() -> gst_event_parse_segment() to retrieve the
292 GstSegment structure from the event.
293 gst_event_copy_segment() to fill a GstSegment structure.
296 Boxed types derived from GstMiniObject.
298 The GstStructure is removed from the public API, use the getters to get
299 a handle to a GstStructure.
301 gst_query_new_application() -> gst_query_new_custom()
303 gst_query_parse_formats_length() -> gst_query_parse_n_formats()
304 gst_query_parse_formats_nth() -> gst_query_parse_nth_format()
306 Some query utility functions no longer use an inout parameter for the
307 destination/query format:
309 - gst_pad_query_position()
310 - gst_pad_query_duration()
311 - gst_pad_query_convert()
312 - gst_pad_query_peer_position()
313 - gst_pad_query_peer_duration()
314 - gst_pad_query_peer_convert()
315 - gst_element_query_position()
316 - gst_element_query_duration()
317 - gst_element_query_convert()
319 gst_element_get_query_types() and gst_pad_get_query_types() with associated
320 functions were removed.
323 Is now a boxed type derived from GstMiniObject.
326 Is now a boxed type derived from GstMiniObject
328 The GstStructure is removed from the public API, use the getters to get
329 a handle to a GstStructure.
332 Is now a boxed type derived from GstMiniObject.
334 GST_VIDEO_CAPS_xxx -> GST_VIDEO_CAPS_MAKE(xxx)
336 Some caps functions now take ownership of the input argument, for
337 efficiency reasons (to avoid unnecessary copies to make them writable):
339 gst_caps_normalize (caps) => caps = gst_caps_normalize (caps)
340 gst_caps_do_simplify (caps) => caps = gst_caps_simplify (caps)
341 gst_caps_merge (caps,caps2) => caps = gst_caps_merge (caps,caps2)
342 gst_caps_merge_structure (caps,st) => caps = gst_caps_merge_structure (caps,st)
343 gst_caps_truncate (caps) => caps = gst_caps_truncate (caps)
345 The compiler should warn about unused return values from these functions,
346 which may help find the places that need to be updated.
350 gst_caps_union() -> gst_caps_merge(): Be careful because _merge takes
351 ownership of the arguments.
354 abs_rate was removed from the public fields, it can be trivially calculated
357 accum was renamed to base. last_stop was renamed to position.
359 The segment info now contains all the information needed to convert buffer
360 timestamps to running_time and stream_time. There is no more segment
361 accumulation, the GstSegment is completely self contained.
363 gst_segment_set_duration() and gst_segment_set_last_stop() are removed,
364 simply modify the structure members duration and position respectively.
366 gst_segment_set_newsegment() is removed, it was used to accumulate segments
367 and is not needed anymore, use gst_segment_copy_into() or modify the segment
370 gst_segment_set_seek() -> gst_segment_do_seek(). Updates the segment values
371 with seek parameters.
374 GST_PLUGIN_FEATURE_NAME() was removed, use GST_OBJECT_NAME() instead.
377 gst_type_find_peek() returns a const guint8 * now.
380 gst_task_create() -> gst_task_new()
383 gst_adapter_peek() is removed, use gst_adapter_map() and gst_adapter_unmap()
384 to get access to raw data from the adapter.
386 Arguments changed from guint to gsize.
388 gst_adapter_prev_timestamp() is removed and should be replaced with
389 gst_adapter_prev_pts() and gst_adapter_prev_dts().
391 * GstBitReader, GstByteReader, GstByteWriter
392 gst_*_reader_new_from_buffer(), gst_*_reader_init_from_buffer() removed, get
393 access to the buffer data with _map() and then use the _new() functions.
395 gst_byte_reader_new_from_buffer() and gst_byte_reader_init_from_buffer()
396 removed, get access to the buffer data and then use the _new() functions.
399 gst_collect_pads_read() removed, use _read_buffer() or _take_buffer() and
400 then use the memory API to get to the memory.
402 * GstBaseSrc, GstBaseTransform, GstBaseSink
403 GstBaseSrc::get_caps(), GstBaseTransform::transform_caps() and
404 GstBaseSink::get_caps() now take a filter GstCaps* parameter to
405 filter the caps and allow better negotiation decisions.
408 GstBaseTransform::transform_caps() now gets the complete caps passed
409 instead of getting it passed structure by structure.
411 GstBaseTransform::event() was renamed to sink_event(). The old function
412 uses the return value to determine if the event should be forwarded or not.
413 The new function has a default implementation that always forwards the event
414 and the return value is simply returned as a result from the event handler.
415 The semantics of the sink_event are thus the same as those for the src_event
418 * GstImplementsInterface
419 has been removed. Interfaces need to be updated to either have
420 is_ready/usable/available() methods, or have GError arguments
421 to their methods so we can return an appropriate error if a
422 particular interface isn't supported for a particular device.
425 uses a GValue based API now that is similar to the 0.10 API but
426 allows bindings to properly use GstIterator and prevents complex
427 return value ownership issues.
430 gst_uri_handler_get_uri() and the get_uri vfunc now return a copy of
433 gst_uri_handler_set_uri() and the set_uri vfunc now take an additional
434 GError argument so the handler can notify the caller why it didn't
435 accept a particular URI.
437 gst_uri_handler_set_uri() now checks if the protocol of the URI passed
438 is one of the protocols advertised by the uri handler, so set_uri vfunc
439 implementations no longer need to check that as well.
442 is now an opaque object instead of being typedefed to a GstStructure. Cast
443 to GstStructure or use gst_structure_* API on it at your own peril (it may
444 still work for now, but might be changed in future).
446 gst_tag_list_new() has been renamed to gst_tag_list_new_empty().
447 gst_tag_list_new_full*() have been renamed to gst_tag_list_new*().
450 has now been merged into GstObject. It does not exists as a individual
451 object anymore. In addition core contains a GstControlSource base class and
452 the GstControlBinding. The actual control sources are in the controller
453 library as before. The 2nd big change is that control sources generate
454 a sequence of gdouble values and those are mapped to the property type and
455 value range by GstControlBindings.
457 For plugins the effect is that gst_controller_init() is gone and
458 gst_object_sync_values() is taking a GstObject * instead of GObject *.
460 For applications the effect is larger. The whole gst_controller_* API is
461 gone and now available in simplified form under gst_object_*. ControlSources
462 are now attached via GstControlBinding to properties. There are no GValue
463 arguments used anymore when programming control sources.
465 gst_controller_new* -> gst_object_set_control_source
466 gst_controller_add_properties -> gst_object_set_control_source
467 gst_controller_set_control_source -> gst_object_set_control_source
468 gst_controller_get_control_source -> gst_object_get_control_source
470 gst_controller_set_property_disabled -> gst_object_set_controlled_property_disabled
472 gst_object_get_value_arrays has been removed. Loop over the controlled
473 properties fetch the value array. Also GstValueArray is gone. The fields of
474 GstValueArray are now passed directly to gst_object_get_value_array as
477 GstInterpolationControlSource has been split. There is a new
478 GstTimedValueControlSource baseclass and 2 sub classes:
479 GstInterpolationControlSource and GstTriggerControlSource. The API for setting
480 and getting the timestamps is in GstTimedValueControlSource.
482 gst_interpolation_control_source_set_interpolation_mode() has been removed.
483 Set the "mode" gobject property on the control-source instead. The possible
484 enum values have been renamed from GST_INTERPOLATE_XXX to
485 GST_INTERPOLATION_MODE_XXX.
489 gst_registry_get_default() -> gst_registry_get()
490 gst_default_registry_*(...) -> gst_registry_*(gst_registry_get(), ...)
494 GST_TYPE_DATE -> G_TYPE_DATE
495 GST_VALUE_HOLDS_DATE(value) -> G_VALUE_HOLDS(value,G_TYPE_DATE)
496 gst_value_set_date() -> g_value_set_boxed()
497 gst_value_get_date() -> g_value_get_boxed()
502 GST_TYPE_G_ERROR / gst_g_error_get_type() -> G_TYPE_ERROR
504 * "codec-data" and "streamheader" field in GstCaps
506 codec-data and stream headers are no longer in GstCaps, but sent as
507 part of a STREAM CONFIG event (which should be sent after the initial
508 CAPS event if needed).
