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
46 gst_element_factory_get_longname -> gst_element_factory_get_metadata
47 gst_element_factory_get_klass -> gst_element_factory_get_metadata
48 gst_element_factory_get_description -> gst_element_factory_get_metadata
49 gst_element_factory_get_author -> gst_element_factory_get_metadata
50 gst_element_factory_get_documentation_uri -> gst_element_factory_get_metadata
51 gst_element_factory_get_icon_name -> gst_element_factory_get_metadata
53 gstelementmetadata.h contains the keys for all standard metadata.
55 Element metadata and pad templates are inherited from parent classes and
56 should be added in class_init instead of base_init.
58 gst_element_class_add_pad_template() takes ownership of the template
60 Elements that change the duration must post DURATION messages on the
61 bus when the duration changes in PAUSED or PLAYING.
63 gst_element_lost_state_full() -> gst_element_lost_state()
64 gst_element_lost_state() -> gst_element_lost_state(, TRUE)
67 gst_pad_get_caps() does not return writable caps anymore and an explicit
68 gst_caps_make_writable() needs to be performed. This was the functionality
69 of gst_pad_get_caps_reffed(), which is removed now.
71 A similar change was done for gst_pad_peer_get_caps() and
72 gst_pad_peer_get_caps_reffed()
74 gst_pad_set_bufferalloc_function(), gst_pad_alloc_buffer() and
75 gst_pad_alloc_buffer_and_set_caps() are removed. Use the ALLOCATION query
76 now to obtain a reference to a bufferpool object that can be used to
79 removed sched_private, it should not be used, use g_object_set_qdata() or
82 Removed GST_PAD_CAPS() use gst_pad_get_current_caps() to get a handle to the
83 currently configured caps.
86 A miniobject is now a simple refcounted structure holding the information
87 common to buffers, events, messages, queries and caps.
89 There is no more GST_TYPE_MINIOBJECT as the type for subclasses.
90 G_TYPE_BOXED can be used as the type of all GstMiniObject based types such
91 as buffers, events, messages, caps, etc. Signals, for example, would use the
92 boxed type if the argument include GstMiniObject derived types.
94 gst_mini_object_new() is removed. You would allocate memory with the the
95 methods specific for the derived type.
97 GstParamSpecMiniObject is removed, use boxed param spec now with the GType
98 of the specific GstMiniObject derived type. Also
99 gst_param_spec_mini_object().
101 gst_param_spec_mini_object() -> g_param_spec_boxed()
103 The specific gst_value_*_mini_object() methods are removed, used the generic
104 boxed methods instead.
106 gst_value_set_mini_object() -> g_value_set_boxed()
107 gst_value_take_mini_object() -> g_value_take_boxed()
108 gst_value_take_get_object() -> g_value_get_boxed()
109 gst_value_take_dup_object() -> g_value_dup_boxed()
111 The GST_MINI_OBJECT_READONLY flag was removed as it used to mark the
112 memory in buffers as READONLY. Marking memory READONLY can now be done
113 with the GstMemory API. Writability of miniobjects is now only done by using
117 A GstBuffer is now a simple boxed type this means that subclassing is not
120 To add data to the buffer you would now use gst_buffer_take_memory() with
121 a GstMemory object containing the data. Multiple memory blocks can added to
122 a GstBuffer that can then be retrieved with gst_buffer_peek_memory().
124 GST_BUFFER_DATA(), GST_BUFFER_MALLOCDATA(), GST_BUFFER_FREE_FUNC() and
125 GST_BUFFER_SIZE() are gone, along with the fields in GstBuffer. Use the
126 memory API to get access to the buffer data. GST_BUFFER_SIZE() can be
127 replaced with gst_buffer_get_size() but if also access to the data is
128 required, gst_buffer_map() can return both the size and data in one go.
130 The most common way to access all the data in a buffer is by using
131 gst_buffer_map() and gst_buffer_unmap(). These calls require you to specify
132 the access mode required to the data and will automatically merge and return
133 a writable copy of the data.
135 The buffer must be writable (gst_buffer_is_writable()) in order to modify
136 the fields, metadata or buffer memory. gst_buffer_make_writable() will not
137 automatically make a writable copy of the memory but will instead increase
138 the refcount of the memory. The _map() and _peek_memory() methods will
139 automatically create writable copies when needed.
141 gst_buffer_make_metadata_writable() is gone, you can replace this safely
142 with gst_buffer_make_writable().
144 gst_buffer_create_sub() is gone and can be safely replaced with
145 gst_buffer_copy_region().
147 Changing the size of the buffer data can be done with gst_buffer_resize(),
148 which will also update the metadata fields correctly. gst_buffer_set_size()
149 is #defined to a special case of gst_buffer_resize() with a 0 offset.
151 gst_buffer_try_new_and_alloc() is replaced with gst_buffer_new_and_alloc(),
152 which now returns NULL when memory allocation fails.
154 GST_BUFFER_CAPS() is gone, caps are not set on buffers anymore but are set
155 on the pads where the buffer is pushed on. Likewise GST_BUFFER_COPY_CAPS is
156 not needed anymore. gst_buffer_get/set_caps() are gone too.
159 The GstBufferList object is much simplified because most of the
160 functionality in the groups is now part of the GstMemory in buffers.
162 The object is reduced to encapsulating an array of buffers that you can send
163 with the regular gst_pad_push_list. The iterator is not needed anymore
164 because you can simply use gst_buffer_list_len() and gst_buffer_list_get()
165 to iterate the array.
167 For dealing with the groups, it's now needed to add the memory blocks to
168 GstBuffer and use the normal buffer API to get and merge the groups.
171 GST_EVENT_SRC is removed. Don't use this anymore.
173 gst_event_new_new_segment_full() -> gst_event_new_new_segment()
174 gst_event_parse_new_segment_full() -> gst_event_parse_new_segment()
176 gst_event_new_qos_full() -> gst_event_new_qos()
177 gst_event_parse_qos_full() -> gst_event_parse_qos()
179 The GstStructure is removed from the public API, use the getters to get
180 a handle to a GstStructure.
183 Boxed types derived from GstMiniObject.
185 The GstStructure is removed from the public API, use the getters to get
186 a handle to a GstStructure.
189 Is now a boxed type derived from GstMiniObject.
192 Is now a boxed type derived from GstMiniObject
194 The GstStructure is removed from the public API, use the getters to get
195 a handle to a GstStructure.
198 Is now a boxed type derived from GstMiniObject.
201 abs_rate was removed from the public fields, it can be trivially calculated
205 gst_type_find_peek() returns a const guin8 * now.
208 gst_adapter_peek() is removed, use gst_adapter_map() and gst_adapter_unmap()
209 to get access to raw data from the adapter.
211 Arguments renamed from guint to gsize.
213 * GstBitReader, GstByteReader, GstByteWriter
214 gst_*_reader_new_from_buffer(), gst_*_reader_init_from_buffer() removed, get
215 access to the buffer data with _map() and then use the _new() functions.
217 gst_byte_reader_new_from_buffer() and gst_byte_reader_init_from_buffer()
218 removed, get access to the buffer data and then use the _new() functions.
221 gst_collect_pads_read() removed, use _read_buffer() or _take_buffer() and
222 then use the memory API to get to the memory.
