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.
64 gst_pad_get_caps() does not return writable caps anymore and an explicit
65 gst_caps_make_writable() needs to be performed. This was the functionality
66 of gst_pad_get_caps_reffed(), which is removed now.
68 A similar change was done for gst_pad_peer_get_caps() and
69 gst_pad_peer_get_caps_reffed()
71 gst_pad_set_bufferalloc_function(), gst_pad_alloc_buffer() and
72 gst_pad_alloc_buffer_and_set_caps() are removed. Use the ALLOCATION query
73 now to obtain a reference to a bufferpool object that can be used to
77 A miniobject is now a simple refcounted structure holding the information
78 common to buffers, events, messages, queries and caps.
80 There is no more GST_TYPE_MINIOBJECT as the type for subclasses.
81 G_TYPE_BOXED can be used as the type of all GstMiniObject based types such
82 as buffers, events, messages, caps, etc. Signals, for example, would use the
83 boxed type if the argument include GstMiniObject derived types.
85 gst_mini_object_new() is removed. You would allocate memory with the the
86 methods specific for the derived type.
88 GstParamSpecMiniObject is removed, use boxed param spec now with the GType
89 of the specific GstMiniObject derived type. Also
90 gst_param_spec_mini_object().
92 gst_param_spec_mini_object() -> g_param_spec_boxed()
94 The specific gst_value_*_mini_object() methods are removed, used the generic
95 boxed methods instead.
97 gst_value_set_mini_object() -> g_value_set_boxed()
98 gst_value_take_mini_object() -> g_value_take_boxed()
99 gst_value_take_get_object() -> g_value_get_boxed()
100 gst_value_take_dup_object() -> g_value_dup_boxed()
102 The GST_MINI_OBJECT_READONLY flag was removed as it used to mark the
103 memory in buffers as READONLY. Marking memory READONLY can now be done
104 with the GstMemory API. Writability of miniobjects is now only done by using
108 A GstBuffer is now a simple boxed type this means that subclassing is not
111 To add data to the buffer you would now use gst_buffer_take_memory() with
112 a GstMemory object containing the data. Multiple memory blocks can added to
113 a GstBuffer that can then be retrieved with gst_buffer_peek_memory().
115 GST_BUFFER_DATA(), GST_BUFFER_MALLOCDATA(), GST_BUFFER_FREE_FUNC() and
116 GST_BUFFER_SIZE() are gone, along with the fields in GstBuffer. Use the
117 memory API to get access to the buffer data. GST_BUFFER_SIZE() can be
118 replaced with gst_buffer_get_size() but if also access to the data is
119 required, gst_buffer_map() can return both the size and data in one go.
121 The most common way to access all the data in a buffer is by using
122 gst_buffer_map() and gst_buffer_unmap(). These calls require you to specify
123 the access mode required to the data and will automatically merge and return
124 a writable copy of the data.
126 The buffer must be writable (gst_buffer_is_writable()) in order to modify
127 the fields, metadata or buffer memory. gst_buffer_make_writable() will not
128 automatically make a writable copy of the memory but will instead increase
129 the refcount of the memory. The _map() and _peek_memory() methods will
130 automatically create writable copies when needed.
132 gst_buffer_make_metadata_writable() is gone, you can replace this safely
133 with gst_buffer_make_writable().
135 gst_buffer_create_sub() is gone and can be safely replaced with
136 gst_buffer_copy_region().
138 Changing the size of the buffer data can be done with gst_buffer_resize(),
139 which will also update the metadata fields correctly. gst_buffer_set_size()
140 is #defined to a special case of gst_buffer_resize() with a 0 offset.
142 gst_buffer_try_new_and_alloc() is replaced with gst_buffer_new_and_alloc(),
143 which now returns NULL when memory allocation fails.
146 The GstBufferList object is much simplified because most of the
147 functionality in the groups is now part of the GstMemory in buffers.
149 The object is reduced to encapsulating an array of buffers that you can send
150 with the regular gst_pad_push_list. The iterator is not needed anymore
151 because you can simply use gst_buffer_list_len() and gst_buffer_list_get()
152 to iterate the array.
154 For dealing with the groups, it's now needed to add the memory blocks to
155 GstBuffer and use the normal buffer API to get and merge the groups.
158 GST_EVENT_SRC is removed. Don't use this anymore.
161 Boxed types derived from GstMiniObject.
164 Is now a boxed type derived from GstMiniObject.
167 Is now a boxed type derived from GstMiniObject
170 Is now a boxed type derived from GstMiniObject.
173 gst_type_find_peek() returns a const guin8 * now.
176 gst_adapter_peek() is removed, use gst_adapter_map() and gst_adapter_unmap()
177 to get access to raw data from the adapter.
179 Arguments renamed from guint to gsize.
181 * GstBitReader, GstByteReader, GstByteWriter
182 gst_*_reader_new_from_buffer(), gst_*_reader_init_from_buffer() removed, get
183 access to the buffer data with _map() and then use the _new() functions.
185 gst_byte_reader_new_from_buffer() and gst_byte_reader_init_from_buffer()
186 removed, get access to the buffer data and then use the _new() functions.
189 gst_collect_pads_read() removed, use _read_buffer() or _take_buffer() and
190 then use the memory API to get to the memory.
