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_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()
126 gst_pad_template_get_caps() returns a new reference of the caps
127 and the return value needs to be unreffed after usage.
129 gst_pad_template_new() does not take ownership of the caps anymore.
131 GstPadTemplate is now created with a floating ref and
132 gst_element_class_add_pad_template() takes ownership of this floating ref.
134 GstPadTemplate instances are considered immutable and must not be
138 A miniobject is now a simple refcounted structure holding the information
139 common to buffers, events, messages, queries and caps.
141 There is no more GST_TYPE_MINIOBJECT as the type for subclasses.
142 G_TYPE_BOXED can be used as the type of all GstMiniObject based types such
143 as buffers, events, messages, caps, etc. Signals, for example, would use the
144 boxed type if the argument include GstMiniObject derived types.
146 gst_mini_object_new() is removed. You would allocate memory with the the
147 methods specific for the derived type.
149 GstParamSpecMiniObject is removed, use boxed param spec now with the GType
150 of the specific GstMiniObject derived type. Also
151 gst_param_spec_mini_object().
153 gst_param_spec_mini_object() -> g_param_spec_boxed()
155 The specific gst_value_*_mini_object() methods are removed, used the generic
156 boxed methods instead.
158 gst_value_set_mini_object() -> g_value_set_boxed()
159 gst_value_take_mini_object() -> g_value_take_boxed()
160 gst_value_take_get_object() -> g_value_get_boxed()
161 gst_value_take_dup_object() -> g_value_dup_boxed()
163 GST_VALUE_HOLDS_MINI_OBJECT() was removed, use G_VALUE_HOLDS_BOXED() or
164 type-specific GST_VALUE_HOLDS_{BUFFER,CAPS,etc.}() instead.
166 The GST_MINI_OBJECT_READONLY flag was removed as it used to mark the
167 memory in buffers as READONLY. Marking memory READONLY can now be done
168 with the GstMemory API. Writability of miniobjects is now only done by using
172 A GstBuffer is now a simple boxed type this means that subclassing is not
175 To add data to the buffer you would now use gst_buffer_take_memory() with
176 a GstMemory object containing the data. Multiple memory blocks can added to
177 a GstBuffer that can then be retrieved with gst_buffer_peek_memory().
179 GST_BUFFER_DATA(), GST_BUFFER_MALLOCDATA(), GST_BUFFER_FREE_FUNC() and
180 GST_BUFFER_SIZE() are gone, along with the fields in GstBuffer. Use the
181 memory API to get access to the buffer data. GST_BUFFER_SIZE() can be
182 replaced with gst_buffer_get_size() but if also access to the data is
183 required, gst_buffer_map() can return both the size and data in one go.
185 The most common way to access all the data in a buffer is by using
186 gst_buffer_map() and gst_buffer_unmap(). These calls require you to specify
187 the access mode required to the data and will automatically merge and return
188 a writable copy of the data.
190 The buffer must be writable (gst_buffer_is_writable()) in order to modify
191 the fields, metadata or buffer memory. gst_buffer_make_writable() will not
192 automatically make a writable copy of the memory but will instead increase
193 the refcount of the memory. The _map() and _peek_memory() methods will
194 automatically create writable copies when needed.
196 gst_buffer_make_metadata_writable() is gone, you can replace this safely
197 with gst_buffer_make_writable().
199 gst_buffer_create_sub() is gone and can be safely replaced with
200 gst_buffer_copy_region().
202 Changing the size of the buffer data can be done with gst_buffer_resize(),
203 which will also update the metadata fields correctly. gst_buffer_set_size()
204 is #defined to a special case of gst_buffer_resize() with a 0 offset.
206 gst_buffer_try_new_and_alloc() is replaced with gst_buffer_new_and_alloc(),
207 which now returns NULL when memory allocation fails.
209 GST_BUFFER_CAPS() is gone, caps are not set on buffers anymore but are set
210 on the pads where the buffer is pushed on. Likewise GST_BUFFER_COPY_CAPS is
211 not needed anymore. gst_buffer_get/set_caps() are gone too.
214 The GstBufferList object is much simplified because most of the
215 functionality in the groups is now part of the GstMemory in buffers.
217 The object is reduced to encapsulating an array of buffers that you can send
218 with the regular gst_pad_push_list. The iterator is not needed anymore
219 because you can simply use gst_buffer_list_len() and gst_buffer_list_get()
220 to iterate the array.
222 For dealing with the groups, it's now needed to add the memory blocks to
223 GstBuffer and use the normal buffer API to get and merge the groups.
227 The GArray of the structure fields are moved to private part and are not
228 accessible from the application anymore. Use the methods to retrieve and
229 modify fields from the array.
232 GST_EVENT_SRC is removed. Don't use this anymore.
234 gst_event_new_qos_full() -> gst_event_new_qos()
235 gst_event_parse_qos_full() -> gst_event_parse_qos()
237 The GstStructure is removed from the public API, use the getters to get
238 a handle to a GstStructure.
240 GST_EVENT_NEWSEGMENT -> GST_EVENT_SEGMENT
242 gst_event_new_new_segment () -> gst_event_new_segment() and it takes a
243 GstSegment structure as an argument.
244 gst_event_parse_new_segment() -> gst_event_parse_segment() to retrieve the
245 GstSegment structure from the event.
246 gst_event_copy_segment() to fill a GstSegment structure.
249 Boxed types derived from GstMiniObject.
251 The GstStructure is removed from the public API, use the getters to get
252 a handle to a GstStructure.
254 gst_query_new_application() -> gst_query_new_custom()
256 gst_query_parse_formats_length() -> gst_query_parse_n_formats()
257 gst_query_parse_formats_nth() -> gst_query_parse_nth_format()
259 Some query utility functionsno longer use an inout parameter for the
260 destination/query format:
262 - gst_pad_query_position()
263 - gst_pad_query_duration()
264 - gst_pad_query_convert()
265 - gst_pad_query_peer_position()
266 - gst_pad_query_peer_duration()
267 - gst_pad_query_peer_convert()
268 - gst_element_query_position()
269 - gst_element_query_duration()
270 - gst_element_query_convert()
273 Is now a boxed type derived from GstMiniObject.
276 Is now a boxed type derived from GstMiniObject
278 The GstStructure is removed from the public API, use the getters to get
279 a handle to a GstStructure.
282 Is now a boxed type derived from GstMiniObject.
285 abs_rate was removed from the public fields, it can be trivially calculated
288 accum was renamed to base. last_stop was renamed to position.
290 The segment info now contains all the information needed to convert buffer
291 timestamps to running_time and stream_time. There is no more segment
292 accumulation, the GstSegment is completely self contained.
294 gst_segment_set_duration() and gst_segment_set_last_stop() are removed,
295 simply modify the structure members duration and position respectively.
297 gst_segment_set_newsegment() is removed, it was used to accumulate segments
298 and is not needed anymore, use gst_segment_copy_into() or modify the segment
301 gst_segment_set_seek() -> gst_segment_do_seek(). Updates the segment values
302 with seek parameters.
305 GST_PLUGIN_FEATURE_NAME() was removed, use GST_OBJECT_NAME() instead.
308 gst_type_find_peek() returns a const guint8 * now.
311 gst_adapter_peek() is removed, use gst_adapter_map() and gst_adapter_unmap()
312 to get access to raw data from the adapter.
314 Arguments renamed from guint to gsize.
316 * GstBitReader, GstByteReader, GstByteWriter
317 gst_*_reader_new_from_buffer(), gst_*_reader_init_from_buffer() removed, get
318 access to the buffer data with _map() and then use the _new() functions.
320 gst_byte_reader_new_from_buffer() and gst_byte_reader_init_from_buffer()
321 removed, get access to the buffer data and then use the _new() functions.
324 gst_collect_pads_read() removed, use _read_buffer() or _take_buffer() and
325 then use the memory API to get to the memory.
327 * GstBaseSrc, GstBaseTransform, GstBaseSink
328 GstBaseSrc::get_caps(), GstBaseTransform::transform_caps() and
329 GstBaseSink::get_caps() now take a filter GstCaps* parameter to
330 filter the caps and allow better negotiation decisions.
333 GstBaseTransform::transform_caps() now gets the complete caps passed
334 instead of getting it passed structure by structure.
336 GstBaseTransform::event() was renamed to sink_event(). The old function
337 uses the return value to determine if the event should be forwarded or not.
338 The new function has a default implementation that always forwards the event
339 and the return value is simply returned as a result from the event handler.
340 The semantics of the sink_event are thus the same as those for the src_event
343 * GstImplementsInterface
344 has been removed. Interfaces need to be updated to either have
345 is_ready/usable/available() methods, or have GError arguments
346 to their methods so we can return an appropriate error if a
347 particular interface isn't supported for a particular device.
350 uses a GValue based API now that is similar to the 0.10 API but
351 allows bindings to properly use GstIterator and prevents complex
352 return value ownership issues.
