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.
16 GST_OBJECT_DISPOSING flag removed
17 GST_OBJECT_IS_DISPOSING removed
18 GST_OBJECT_FLOATING flag remove, GstObject is now GInitiallyUnowned
19 GST_OBJECT_IS_FLOATING removed, use g_object_is_floating()
21 GST_CLASS_GET_LOCK, GST_CLASS_LOCK, GST_CLASS_TRYLOCK, GST_CLASS_UNLOCK,
22 used to be a workaround for thread-unsafe glib < 2.8
24 gst_object_ref_sink() has gpointer as result to make it more like the
27 gst_object_sink() removed, use gst_object_ref_sink() instead.
29 gst_class_signal_connect() removed, was only used for XML
31 parent-set and parent-unset signals removed. Use notify:parent. Currently
32 still disabled because of deep notify locking issues.
35 GstElementDetails is removed and replaced with more generic metadata.
37 gst_element_class_set_details_simple() -> gst_element_class_set_metadata()
38 gst_element_class_set_documentation_uri -> gst_element_class_add_metadata
39 gst_element_class_set_icon_name -> gst_element_class_add_metadata
41 gst_element_factory_get_longname -> gst_element_factory_get_metadata
42 gst_element_factory_get_klass -> gst_element_factory_get_metadata
43 gst_element_factory_get_description -> gst_element_factory_get_metadata
44 gst_element_factory_get_author -> gst_element_factory_get_metadata
45 gst_element_factory_get_documentation_uri -> gst_element_factory_get_metadata
46 gst_element_factory_get_icon_name -> gst_element_factory_get_metadata
48 gstelementmetadata.h contains the keys for all standard metadata.
50 Element metadata and pad templates are inherited from parent classes and
51 should be added in class_init instead of base_init.
53 gst_element_class_add_pad_template() takes ownership of the template
55 Elements that change the duration must post DURATION messages on the
56 bus when the duration changes in PAUSED or PLAYING.
59 gst_pad_get_caps() does not return writable caps anymore and an explicit
60 gst_caps_make_writable() needs to be performed. This was the functionality
61 of gst_pad_get_caps_reffed(), which is removed now.
63 A similar change was done for gst_pad_peer_get_caps() and
64 gst_pad_peer_get_caps_reffed()
67 A miniobject is now a simple refcounted structure holding the information
68 common to buffers, events, messages, queries and caps.
70 There is no more GST_TYPE_MINIOBJECT as the type for subclasses.
71 G_TYPE_BOXED can be used as the type of all GstMiniObject based types such
72 as buffers, events, messages, caps, etc. Signals, for example, would use the
73 boxed type if the argument include GstMiniObject derived types.
75 gst_mini_object_new() is removed. You would allocate memory with the the
76 methods specific for the derived type.
78 GstParamSpecMiniObject is removed, use boxed param spec now with the GType
79 of the specific GstMiniObject derived type. Also
80 gst_param_spec_mini_object().
82 gst_param_spec_mini_object() -> g_param_spec_boxed()
84 The specific gst_value_*_mini_object() methods are removed, used the generic
85 boxed methods instead.
87 gst_value_set_mini_object() -> g_value_set_boxed()
88 gst_value_take_mini_object() -> g_value_take_boxed()
89 gst_value_take_get_object() -> g_value_get_boxed()
90 gst_value_take_dup_object() -> g_value_dup_boxed()
92 The GST_MINI_OBJECT_READONLY flag was removed as it used to mark the
93 memory in buffers as READONLY. Marking memory READONLY can now be done
94 with the GstMemory API. Writability of miniobjects is now only done by using
98 A GstBuffer is now a simple boxed type this means that subclassing is not
101 To add data to the buffer you would now use gst_buffer_take_memory() with
102 a GstMemory object containing the data. Multiple memory blocks can added to
103 a GstBuffer that can then be retrieved with gst_buffer_peek_memory().
105 GST_BUFFER_DATA(), GST_BUFFER_MALLOCDATA(), GST_BUFFER_FREE_FUNC() and
106 GST_BUFFER_SIZE() are gone, along with the fields in GstBuffer. Use the
107 memory API to get access to the buffer data. GST_BUFFER_SIZE() can be
108 replaced with gst_buffer_get_size() but if also access to the data is
109 required, gst_buffer_map() can return both the size and data in one go.
111 The most common way to access all the data in a buffer is by using
112 gst_buffer_map() and gst_buffer_unmap(). These calls require you to specify
113 the access mode required to the data and will automatically merge and return
114 a writable copy of the data.
116 The buffer must be writable (gst_buffer_is_writable()) in order to modify
117 the fields, metadata or buffer memory. gst_buffer_make_writable() will not
118 automatically make a writable copy of the memory but will instead increase
119 the refcount of the memory. The _map() and _peek_memory() methods will
120 automatically create writable copies when needed.
122 gst_buffer_make_metadata_writable() is gone, you can replace this safely
123 with gst_buffer_make_writable().
125 gst_buffer_create_sub() is gone and can be safely replaced with
126 gst_buffer_copy_region().
128 Changing the size of the buffer data can be done with gst_buffer_resize(),
129 which will also update the metadata fields correctly. gst_buffer_set_size()
130 is #defined to a special case of gst_buffer_resize() with a 0 offset.
132 gst_buffer_try_new_and_alloc() is replaced with gst_buffer_new_and_alloc(),
133 which now returns NULL when memory allocation fails.
136 The GstBufferList object is much simplified because most of the
137 functionality in the groups is now part of the GstMemory in buffers.
139 The object is reduced to encapsulating an array of buffers that you can send
140 with the regular gst_pad_push_list. The iterator is not needed anymore
141 because you can simply use gst_buffer_list_len() and gst_buffer_list_get()
142 to iterate the array.
144 For dealing with the groups, it's now needed to add the memory blocks to
145 GstBuffer and use the normal buffer API to get and merge the groups.
149 Boxed types derived from GstMiniObject.
152 Is now a boxed type derived from GstMiniObject.
155 Is now a boxed type derived from GstMiniObject
158 Is now a boxed type derived from GstMiniObject.
161 gst_type_find_peek() returns a const guin8 * now.
164 gst_adapter_peek() is removed, use gst_adapter_map() and gst_adapter_unmap()
165 to get access to raw data from the adapter.
167 Arguments renamed from guint to gsize.
169 * GstBitReader, GstByteReader, GstByteWriter
170 gst_*_reader_new_from_buffer(), gst_*_reader_init_from_buffer() removed, get
171 access to the buffer data with _map() and then use the _new() functions.
173 gst_byte_reader_new_from_buffer() and gst_byte_reader_init_from_buffer()
174 removed, get access to the buffer data and then use the _new() functions.
177 gst_collect_pads_read() removed, use _read_buffer() or _take_buffer() and
178 then use the memory API to get to the memory.
