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() does not return writable caps anymore and an explicit
76 gst_caps_make_writable() needs to be performed. This was the functionality
77 of gst_pad_get_caps_reffed(), which is removed now.
79 A similar change was done for gst_pad_peer_get_caps() and
80 gst_pad_peer_get_caps_reffed()
82 gst_pad_set_bufferalloc_function(), gst_pad_alloc_buffer() and
83 gst_pad_alloc_buffer_and_set_caps() are removed. Use the ALLOCATION query
84 now when negotiating formats to obtain a reference to a bufferpool object
85 that can be used to allocate buffers using gst_buffer_pool_acquire_buffer().
87 removed sched_private, it should not be used, use g_object_set_qdata() or
90 Removed GST_PAD_CAPS() use gst_pad_get_current_caps() to get a handle to the
91 currently configured caps.
93 GstPadGetCapsFunction, gst_pad_get_caps(), gst_pad_peer_get_caps(),
94 gst_pad_proxy_getcaps() now takes a GstCaps* parameter to inform
95 the other side about the possible caps and preferences.
97 gst_pad_get_pad_template_caps() and gst_pad_get_pad_template()
98 return a new reference of the caps or template now and the return
99 value needs to be unreffed after usage.
101 gst_pad_set_caps() now pushes a CAPS event for backward compatibility.
102 Consider sending the CAPS event yourself. It is not possible anymore to set
105 gst_pad_set_checkgetrange_function() and gst_pad_check_pull_range() are
106 gone, use the SCHEDULING query now.
108 gst_pad_set_blocked(), gst_pad_set_blocked_async(),
109 gst_pad_set_blocked_async_full() are removed, use the gst_pad_add_probe()
110 method with the GST_PAD_PROBE_TYPE_BLOCK to get the same result as the async
111 blocking version. There is no more sync version of blocking, this is in
112 general dangerous and can be implemented using the callbacks if needed.
114 gst_pad_add_data_probe(), gst_pad_add_data_probe_full(),
115 gst_pad_remove_data_probe(), gst_pad_add_event_probe(),
116 gst_pad_add_event_probe_full(), gst_pad_remove_event_probe(),
117 gst_pad_add_buffer_probe(), gst_pad_add_buffer_probe_full(),
118 gst_pad_remove_buffer_probe() are removed. Use gst_pad_add_probe() and
119 gst_pad_remove_probe() for equivalent functionality.
121 The have-data signal was removed from pads, it was never supposed to be used
122 without calling the _add_.*_probe() methods.
124 The request-link signal was removed. It was never used.
126 gst_pad_get_negotiated_caps() -> get_pad_get_current_caps()
128 GST_FLOW_UNEXPECTED -> GST_FLOW_EOS
130 GstActivateMode -> GstPadActivateMode, GST_ACTIVATE_* -> GST_PAD_ACTIVATE_*
132 The GstPadAcceptCapsFunction was removed and replaced with a
133 GST_QUERY_ACCEPT_CAPS query.
135 The GstPadFixateCapsFunction was removed. It has no replacement, you can
136 simply do the fixation in the element or use a vmethod from the base class
139 The GstPadGetCapsFunction was removed and replaced with a GST_QUERY_CAPS
142 gst_pad_proxy_getcaps() -> gst_pad_proxy_query_caps()
143 gst_pad_get_caps() -> gst_pad_query_caps()
144 gst_pad_peer_get_caps() -> gst_pad_peer_query_caps()
145 gst_pad_accept_caps() -> gst_pad_query_accept_caps()
146 gst_pad_peer_accept_caps() -> gst_pad_peer_query_accept_caps()
147 gst_pad_query_peer_*() -> gst_pad_peer_query_*()
151 gst_pad_template_get_caps() returns a new reference of the caps
152 and the return value needs to be unreffed after usage.
154 gst_pad_template_new() does not take ownership of the caps anymore.
156 GstPadTemplate is now created with a floating ref and
157 gst_element_class_add_pad_template() takes ownership of this floating ref.
159 GstPadTemplate instances are considered immutable and must not be
163 A miniobject is now a simple refcounted structure holding the information
164 common to buffers, events, messages, queries and caps.
166 There is no more GST_TYPE_MINIOBJECT as the type for subclasses.
167 G_TYPE_BOXED can be used as the type of all GstMiniObject based types such
168 as buffers, events, messages, caps, etc. Signals, for example, would use the
169 boxed type if the argument include GstMiniObject derived types.
171 gst_mini_object_new() is removed. You would allocate memory with the the
172 methods specific for the derived type.
174 GstParamSpecMiniObject is removed, use boxed param spec now with the GType
175 of the specific GstMiniObject derived type. Also
176 gst_param_spec_mini_object().
178 gst_param_spec_mini_object() -> g_param_spec_boxed()
180 The specific gst_value_*_mini_object() methods are removed, used the generic
181 boxed methods instead.
183 gst_value_set_mini_object() -> g_value_set_boxed()
184 gst_value_take_mini_object() -> g_value_take_boxed()
185 gst_value_take_get_object() -> g_value_get_boxed()
186 gst_value_take_dup_object() -> g_value_dup_boxed()
188 GST_VALUE_HOLDS_MINI_OBJECT() was removed, use G_VALUE_HOLDS_BOXED() or
189 type-specific GST_VALUE_HOLDS_{BUFFER,CAPS,etc.}() instead.
191 The GST_MINI_OBJECT_READONLY flag was removed as it used to mark the
192 memory in buffers as READONLY. Marking memory READONLY can now be done
193 with the GstMemory API. Writability of miniobjects is now only done by using
197 A GstBuffer is now a simple boxed type this means that subclassing is not
200 To add data to the buffer you would now use gst_buffer_take_memory() with
201 a GstMemory object containing the data. Multiple memory blocks can added to
202 a GstBuffer that can then be retrieved with gst_buffer_peek_memory().
204 GST_BUFFER_DATA(), GST_BUFFER_MALLOCDATA(), GST_BUFFER_FREE_FUNC() and
205 GST_BUFFER_SIZE() are gone, along with the fields in GstBuffer. Use the
206 memory API to get access to the buffer data. GST_BUFFER_SIZE() can be
207 replaced with gst_buffer_get_size() but if also access to the data is
208 required, gst_buffer_map() can return both the size and data in one go.
210 The most common way to access all the data in a buffer is by using
211 gst_buffer_map() and gst_buffer_unmap(). These calls require you to specify
212 the access mode required to the data and will automatically merge and return
213 a writable copy of the data.
215 The buffer must be writable (gst_buffer_is_writable()) in order to modify
216 the fields, metadata or buffer memory. gst_buffer_make_writable() will not
217 automatically make a writable copy of the memory but will instead increase
218 the refcount of the memory. The _map() and _peek_memory() methods will
219 automatically create writable copies when needed.
221 gst_buffer_make_metadata_writable() is gone, you can replace this safely
222 with gst_buffer_make_writable().
224 gst_buffer_copy_metadata() is gone, use gst_buffer_copy_into() instead and
225 mind use GST_BUFFER_COPY_METADATA instead of the former GST_BUFFER_COPY_ALL.
227 gst_buffer_create_sub() is gone and can be safely replaced with
228 gst_buffer_copy_region().
230 Changing the size of the buffer data can be done with gst_buffer_resize(),
231 which will also update the metadata fields correctly. gst_buffer_set_size()
232 is #defined to a special case of gst_buffer_resize() with a 0 offset.
234 gst_buffer_try_new_and_alloc() is replaced with gst_buffer_new_and_alloc(),
235 which now returns NULL when memory allocation fails.
237 GST_BUFFER_CAPS() is gone, caps are not set on buffers anymore but are set
238 on the pads where the buffer is pushed on. Likewise GST_BUFFER_COPY_CAPS is
239 not needed anymore. gst_buffer_get/set_caps() are gone too.
241 GST_BUFFER_TIMESTAMP is gone, use GST_BUFFER_PTS or GST_BUFFER_DTS instead.
242 Likewise GST_BUFFER_TIMESTAMP_IS_VALID() was changed to
243 GST_BUFFER_PTS_IS_VALID and GST_BUFFER_DTS_IS_VALID
246 The GstBufferList object is much simplified because most of the
247 functionality in the groups is now part of the GstMemory in buffers.
249 The object is reduced to encapsulating an array of buffers that you can send
250 with the regular gst_pad_push_list. The iterator is not needed anymore
251 because you can simply use gst_buffer_list_length() and gst_buffer_list_get()
252 to iterate the array.
254 For dealing with the groups, it's now needed to add the memory blocks to
255 GstBuffer and use the normal buffer API to get and merge the groups.
257 gst_buffer_list_sized_new() -> gst_buffer_list_new_sized()
258 gst_buffer_list_len() -> gst_buffer_list_length()
262 The GArray of the structure fields are moved to private part and are not
263 accessible from the application anymore. Use the methods to retrieve and
264 modify fields from the array.
266 gst_structure_empty_new() -> gst_structure_new_empty()
267 gst_structure_id_empty_new() -> gst_structure_new_id_empty()
268 gst_structure_id_new() -> gst_structure_new_id()
271 Boxed types derived from GstMiniObject.
273 GST_EVENT_SRC is removed. Don't use this anymore.
275 gst_event_new_qos_full() -> gst_event_new_qos()
276 gst_event_parse_qos_full() -> gst_event_parse_qos()
278 The GstStructure is removed from the public API, use the getters to get
279 a handle to a GstStructure.
281 GST_EVENT_NEWSEGMENT -> GST_EVENT_SEGMENT
283 gst_event_new_new_segment () -> gst_event_new_segment() and it takes a
284 GstSegment structure as an argument.
285 gst_event_parse_new_segment() -> gst_event_parse_segment() to retrieve the
286 GstSegment structure from the event.
287 gst_event_copy_segment() to fill a GstSegment structure.
290 Boxed types derived from GstMiniObject.
292 The GstStructure is removed from the public API, use the getters to get
293 a handle to a GstStructure.
295 gst_query_new_application() -> gst_query_new_custom()
297 gst_query_parse_formats_length() -> gst_query_parse_n_formats()
298 gst_query_parse_formats_nth() -> gst_query_parse_nth_format()
300 Some query utility functions no longer use an inout parameter for the
301 destination/query format:
303 - gst_pad_query_position()
304 - gst_pad_query_duration()
305 - gst_pad_query_convert()
306 - gst_pad_query_peer_position()
307 - gst_pad_query_peer_duration()
308 - gst_pad_query_peer_convert()
309 - gst_element_query_position()
310 - gst_element_query_duration()
311 - gst_element_query_convert()
313 gst_element_get_query_types() and gst_pad_get_query_types() with associated
314 functions were removed.
317 Is now a boxed type derived from GstMiniObject.
320 Is now a boxed type derived from GstMiniObject
322 The GstStructure is removed from the public API, use the getters to get
323 a handle to a GstStructure.
326 Is now a boxed type derived from GstMiniObject.
329 abs_rate was removed from the public fields, it can be trivially calculated
332 accum was renamed to base. last_stop was renamed to position.
334 The segment info now contains all the information needed to convert buffer
335 timestamps to running_time and stream_time. There is no more segment
336 accumulation, the GstSegment is completely self contained.
338 gst_segment_set_duration() and gst_segment_set_last_stop() are removed,
339 simply modify the structure members duration and position respectively.
341 gst_segment_set_newsegment() is removed, it was used to accumulate segments
342 and is not needed anymore, use gst_segment_copy_into() or modify the segment
345 gst_segment_set_seek() -> gst_segment_do_seek(). Updates the segment values
346 with seek parameters.
349 GST_PLUGIN_FEATURE_NAME() was removed, use GST_OBJECT_NAME() instead.
352 gst_type_find_peek() returns a const guint8 * now.
356 gst_task_create() -> gst_task_new()
359 gst_adapter_peek() is removed, use gst_adapter_map() and gst_adapter_unmap()
360 to get access to raw data from the adapter.
362 Arguments changed from guint to gsize.
364 gst_adapter_prev_timestamp() is removed and should be replaced with
365 gst_adapter_prev_pts() and gst_adapter_prev_dts().
367 * GstBitReader, GstByteReader, GstByteWriter
368 gst_*_reader_new_from_buffer(), gst_*_reader_init_from_buffer() removed, get
369 access to the buffer data with _map() and then use the _new() functions.
371 gst_byte_reader_new_from_buffer() and gst_byte_reader_init_from_buffer()
372 removed, get access to the buffer data and then use the _new() functions.
375 gst_collect_pads_read() removed, use _read_buffer() or _take_buffer() and
376 then use the memory API to get to the memory.
378 * GstBaseSrc, GstBaseTransform, GstBaseSink
379 GstBaseSrc::get_caps(), GstBaseTransform::transform_caps() and
380 GstBaseSink::get_caps() now take a filter GstCaps* parameter to
381 filter the caps and allow better negotiation decisions.
384 GstBaseTransform::transform_caps() now gets the complete caps passed
385 instead of getting it passed structure by structure.
387 GstBaseTransform::event() was renamed to sink_event(). The old function
388 uses the return value to determine if the event should be forwarded or not.
389 The new function has a default implementation that always forwards the event
390 and the return value is simply returned as a result from the event handler.
391 The semantics of the sink_event are thus the same as those for the src_event
394 * GstImplementsInterface
395 has been removed. Interfaces need to be updated to either have
396 is_ready/usable/available() methods, or have GError arguments
397 to their methods so we can return an appropriate error if a
398 particular interface isn't supported for a particular device.
401 uses a GValue based API now that is similar to the 0.10 API but
402 allows bindings to properly use GstIterator and prevents complex
403 return value ownership issues.
406 gst_uri_handler_get_uri() and the get_uri vfunc now return a copy of
409 gst_uri_handler_set_uri() and the set_uri vfunc now take an additional
410 GError argument so the handler can notify the caller why it didn't
411 accept a particular URI.
413 gst_uri_handler_set_uri() now checks if the protocol of the URI passed
414 is one of the protocols advertised by the uri handler, so set_uri vfunc
415 implementations no longer need to check that as well.
418 is now an opaque object instead of being typedefed to a GstStructure. Cast
419 to GstStructure or use gst_structure_* API on it at your own peril (it may
420 still work for now, but might be changed in future).
422 gst_tag_list_new() has been renamed to gst_tag_list_new_empty().
423 gst_tag_list_new_full*() have been renamed to gst_tag_list_new*().
426 has now been merged into GstObject. The control sources are in the
427 controller library still.
429 For plugins the effect is that gst_controller_init() is gone and
430 gst_object_sync_values() is taking a GstObject * instead of GObject *.
432 For applications the effect is larger. The whole gst_controller_* API is
433 gone and now available in simplified form under gst_object_*. There is no
434 more GstController object. Attach a control source to a property to control
435 it and attach NULL to un-control it.
437 gst_controller_new* -> gst_object_set_control_source
438 gst_controller_add_properties -> gst_object_set_control_source
439 gst_controller_set_control_source -> gst_object_set_control_source
440 gst_controller_get_control_source -> gst_object_get_control_source
442 gst_controller_set_property_disabled -> gst_object_set_controlled_property_disabled
