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()
72 gst_pad_get_caps() does not return writable caps anymore and an explicit
73 gst_caps_make_writable() needs to be performed. This was the functionality
74 of gst_pad_get_caps_reffed(), which is removed now.
76 A similar change was done for gst_pad_peer_get_caps() and
77 gst_pad_peer_get_caps_reffed()
79 gst_pad_set_bufferalloc_function(), gst_pad_alloc_buffer() and
80 gst_pad_alloc_buffer_and_set_caps() are removed. Use the ALLOCATION query
81 now to obtain a reference to a bufferpool object that can be used to
84 removed sched_private, it should not be used, use g_object_set_qdata() or
87 Removed GST_PAD_CAPS() use gst_pad_get_current_caps() to get a handle to the
88 currently configured caps.
90 GstPadGetCapsFunction, gst_pad_get_caps(), gst_pad_peer_get_caps(),
91 gst_pad_proxy_getcaps() now takes a GstCaps* parameter to inform
92 the other side about the possible caps and preferences.
94 gst_pad_get_pad_template_caps() and gst_pad_get_pad_template()
95 return a new reference of the caps or template now and the return
96 value needs to be unreffed after usage.
98 gst_pad_set_caps() now pushes a CAPS event for backward compatibility.
99 Consider sending the CAPS event yourself. It is not possible anymore to set
102 gst_pad_set_checkgetrange_function() and gst_pad_check_pull_range() are
103 gone, use the SCHEDULING query now.
105 gst_pad_set_blocked(), gst_pad_set_blocked_async(),
106 gst_pad_set_blocked_async_full() are removed, use the gst_pad_add_probe()
107 method with the GST_PAD_PROBE_TYPE_BLOCK to get the same result as the async
108 blocking version. There is no more sync version of blocking, this is in
109 general dangerous and can be implemented using the callbacks if needed.
111 gst_pad_add_data_probe(), gst_pad_add_data_probe_full(),
112 gst_pad_remove_data_probe(), gst_pad_add_event_probe(),
113 gst_pad_add_event_probe_full(), gst_pad_remove_event_probe(),
114 gst_pad_add_buffer_probe(), gst_pad_add_buffer_probe_full(),
115 gst_pad_remove_buffer_probe() are removed. Use gst_pad_add_probe() and
116 gst_pad_remove_probe() for equivalent functionality.
118 The have-data signal was removed from pads, it was never supposed to be used
119 without calling the _add_.*_probe() methods.
121 The request-link signal was removed. It was never used.
123 gst_pad_get_negotiated_caps() -> get_pad_get_current_caps()
125 GST_FLOW_UNEXPECTED -> GST_FLOW_EOS
127 GstActivateMode -> GstPadActivateMode, GST_ACTIVATE_* -> GST_PAD_ACTIVATE_*
130 gst_pad_template_get_caps() returns a new reference of the caps
131 and the return value needs to be unreffed after usage.
133 gst_pad_template_new() does not take ownership of the caps anymore.
135 GstPadTemplate is now created with a floating ref and
136 gst_element_class_add_pad_template() takes ownership of this floating ref.
138 GstPadTemplate instances are considered immutable and must not be
142 A miniobject is now a simple refcounted structure holding the information
143 common to buffers, events, messages, queries and caps.
145 There is no more GST_TYPE_MINIOBJECT as the type for subclasses.
146 G_TYPE_BOXED can be used as the type of all GstMiniObject based types such
147 as buffers, events, messages, caps, etc. Signals, for example, would use the
148 boxed type if the argument include GstMiniObject derived types.
150 gst_mini_object_new() is removed. You would allocate memory with the the
151 methods specific for the derived type.
153 GstParamSpecMiniObject is removed, use boxed param spec now with the GType
154 of the specific GstMiniObject derived type. Also
155 gst_param_spec_mini_object().
157 gst_param_spec_mini_object() -> g_param_spec_boxed()
159 The specific gst_value_*_mini_object() methods are removed, used the generic
160 boxed methods instead.
162 gst_value_set_mini_object() -> g_value_set_boxed()
163 gst_value_take_mini_object() -> g_value_take_boxed()
164 gst_value_take_get_object() -> g_value_get_boxed()
165 gst_value_take_dup_object() -> g_value_dup_boxed()
167 GST_VALUE_HOLDS_MINI_OBJECT() was removed, use G_VALUE_HOLDS_BOXED() or
168 type-specific GST_VALUE_HOLDS_{BUFFER,CAPS,etc.}() instead.
170 The GST_MINI_OBJECT_READONLY flag was removed as it used to mark the
171 memory in buffers as READONLY. Marking memory READONLY can now be done
172 with the GstMemory API. Writability of miniobjects is now only done by using
176 A GstBuffer is now a simple boxed type this means that subclassing is not
179 To add data to the buffer you would now use gst_buffer_take_memory() with
180 a GstMemory object containing the data. Multiple memory blocks can added to
181 a GstBuffer that can then be retrieved with gst_buffer_peek_memory().
183 GST_BUFFER_DATA(), GST_BUFFER_MALLOCDATA(), GST_BUFFER_FREE_FUNC() and
184 GST_BUFFER_SIZE() are gone, along with the fields in GstBuffer. Use the
185 memory API to get access to the buffer data. GST_BUFFER_SIZE() can be
186 replaced with gst_buffer_get_size() but if also access to the data is
187 required, gst_buffer_map() can return both the size and data in one go.
189 The most common way to access all the data in a buffer is by using
190 gst_buffer_map() and gst_buffer_unmap(). These calls require you to specify
191 the access mode required to the data and will automatically merge and return
192 a writable copy of the data.
194 The buffer must be writable (gst_buffer_is_writable()) in order to modify
195 the fields, metadata or buffer memory. gst_buffer_make_writable() will not
196 automatically make a writable copy of the memory but will instead increase
197 the refcount of the memory. The _map() and _peek_memory() methods will
198 automatically create writable copies when needed.
200 gst_buffer_make_metadata_writable() is gone, you can replace this safely
201 with gst_buffer_make_writable().
203 gst_buffer_create_sub() is gone and can be safely replaced with
204 gst_buffer_copy_region().
206 Changing the size of the buffer data can be done with gst_buffer_resize(),
207 which will also update the metadata fields correctly. gst_buffer_set_size()
208 is #defined to a special case of gst_buffer_resize() with a 0 offset.
210 gst_buffer_try_new_and_alloc() is replaced with gst_buffer_new_and_alloc(),
211 which now returns NULL when memory allocation fails.
213 GST_BUFFER_CAPS() is gone, caps are not set on buffers anymore but are set
214 on the pads where the buffer is pushed on. Likewise GST_BUFFER_COPY_CAPS is
215 not needed anymore. gst_buffer_get/set_caps() are gone too.
217 GST_BUFFER_TIMESTAMP is gone, use GST_BUFFER_PTS or GST_BUFFER_DTS instead.
218 Likewise GST_BUFFER_TIMESTAMP_IS_VALID() was changed to
219 GST_BUFFER_PTS_IS_VALID and GST_BUFFER_DTS_IS_VALID
222 The GstBufferList object is much simplified because most of the
223 functionality in the groups is now part of the GstMemory in buffers.
225 The object is reduced to encapsulating an array of buffers that you can send
226 with the regular gst_pad_push_list. The iterator is not needed anymore
227 because you can simply use gst_buffer_list_length() and gst_buffer_list_get()
228 to iterate the array.
230 For dealing with the groups, it's now needed to add the memory blocks to
231 GstBuffer and use the normal buffer API to get and merge the groups.
233 gst_buffer_list_sized_new() -> gst_buffer_list_new_sized()
234 gst_buffer_list_len() -> gst_buffer_list_length()
238 The GArray of the structure fields are moved to private part and are not
239 accessible from the application anymore. Use the methods to retrieve and
240 modify fields from the array.
242 gst_structure_empty_new() -> gst_structure_new_empty()
243 gst_structure_id_empty_new() -> gst_structure_new_id_empty()
244 gst_structure_id_new() -> gst_structure_new_id()
247 GST_EVENT_SRC is removed. Don't use this anymore.
249 gst_event_new_qos_full() -> gst_event_new_qos()
250 gst_event_parse_qos_full() -> gst_event_parse_qos()
252 The GstStructure is removed from the public API, use the getters to get
253 a handle to a GstStructure.
255 GST_EVENT_NEWSEGMENT -> GST_EVENT_SEGMENT
257 gst_event_new_new_segment () -> gst_event_new_segment() and it takes a
258 GstSegment structure as an argument.
259 gst_event_parse_new_segment() -> gst_event_parse_segment() to retrieve the
260 GstSegment structure from the event.
261 gst_event_copy_segment() to fill a GstSegment structure.
264 Boxed types derived from GstMiniObject.
266 The GstStructure is removed from the public API, use the getters to get
267 a handle to a GstStructure.
269 gst_query_new_application() -> gst_query_new_custom()
271 gst_query_parse_formats_length() -> gst_query_parse_n_formats()
272 gst_query_parse_formats_nth() -> gst_query_parse_nth_format()
274 Some query utility functions no longer use an inout parameter for the
275 destination/query format:
277 - gst_pad_query_position()
278 - gst_pad_query_duration()
279 - gst_pad_query_convert()
280 - gst_pad_query_peer_position()
281 - gst_pad_query_peer_duration()
282 - gst_pad_query_peer_convert()
283 - gst_element_query_position()
284 - gst_element_query_duration()
285 - gst_element_query_convert()
288 Is now a boxed type derived from GstMiniObject.
291 Is now a boxed type derived from GstMiniObject
293 The GstStructure is removed from the public API, use the getters to get
294 a handle to a GstStructure.
297 Is now a boxed type derived from GstMiniObject.
300 abs_rate was removed from the public fields, it can be trivially calculated
303 accum was renamed to base. last_stop was renamed to position.
305 The segment info now contains all the information needed to convert buffer
306 timestamps to running_time and stream_time. There is no more segment
307 accumulation, the GstSegment is completely self contained.
309 gst_segment_set_duration() and gst_segment_set_last_stop() are removed,
310 simply modify the structure members duration and position respectively.
312 gst_segment_set_newsegment() is removed, it was used to accumulate segments
313 and is not needed anymore, use gst_segment_copy_into() or modify the segment
316 gst_segment_set_seek() -> gst_segment_do_seek(). Updates the segment values
317 with seek parameters.
320 GST_PLUGIN_FEATURE_NAME() was removed, use GST_OBJECT_NAME() instead.
323 gst_type_find_peek() returns a const guint8 * now.
327 gst_task_create() -> gst_task_new()
330 gst_adapter_peek() is removed, use gst_adapter_map() and gst_adapter_unmap()
331 to get access to raw data from the adapter.
333 Arguments changed from guint to gsize.
335 gst_adapter_prev_timestamp() is removed and should be replaced with
336 gst_adapter_prev_pts() and gst_adapter_prev_dts().
338 * GstBitReader, GstByteReader, GstByteWriter
339 gst_*_reader_new_from_buffer(), gst_*_reader_init_from_buffer() removed, get
340 access to the buffer data with _map() and then use the _new() functions.
342 gst_byte_reader_new_from_buffer() and gst_byte_reader_init_from_buffer()
343 removed, get access to the buffer data and then use the _new() functions.
346 gst_collect_pads_read() removed, use _read_buffer() or _take_buffer() and
347 then use the memory API to get to the memory.
349 * GstBaseSrc, GstBaseTransform, GstBaseSink
350 GstBaseSrc::get_caps(), GstBaseTransform::transform_caps() and
351 GstBaseSink::get_caps() now take a filter GstCaps* parameter to
352 filter the caps and allow better negotiation decisions.
355 GstBaseTransform::transform_caps() now gets the complete caps passed
356 instead of getting it passed structure by structure.
358 GstBaseTransform::event() was renamed to sink_event(). The old function
359 uses the return value to determine if the event should be forwarded or not.
360 The new function has a default implementation that always forwards the event
361 and the return value is simply returned as a result from the event handler.
362 The semantics of the sink_event are thus the same as those for the src_event
365 * GstImplementsInterface
366 has been removed. Interfaces need to be updated to either have
367 is_ready/usable/available() methods, or have GError arguments
368 to their methods so we can return an appropriate error if a
369 particular interface isn't supported for a particular device.
372 uses a GValue based API now that is similar to the 0.10 API but
373 allows bindings to properly use GstIterator and prevents complex
374 return value ownership issues.
377 is now an opaque object instead of being typedefed to a GstStructure. Cast
378 to GstStructure or use gst_structure_* API on it at your own peril (it may
379 still work for now, but might be changed in future).
381 gst_tag_list_new() has been renamed to gst_tag_list_new_empty().
382 gst_tag_list_new_full*() have been renamed to gst_tag_list_new*().
