1 Never assume the API of libav* to be stable unless at least 1 week has passed since
2 the last major version increase.
3 The last version increases were:
6 libavfilter: 2009-10-18
13 API changes, most recent first:
15 2009-11-26 - r20611 - lavfi 1.11.0 - AVFilter
16 Remove the next field from AVFilter, this is not anymore required.
18 2009-11-25 - r20607 - lavfi 1.10.0 - avfilter_next()
19 Introduce the avfilter_next() function.
21 2009-11-25 - r20605 - lavfi 1.9.0 - avfilter_register()
22 Change the signature of avfilter_register() to make it return an
23 int. This is required since now the registration operation may fail.
25 2009-11-25 - r20603 - lavu 50.5.0 - pixdesc.h API
26 Make the pixdesc.h API public.
28 2009-10-27 - r20385 - lavfi 1.5.0 - AVFilter.next
29 Add a next field to AVFilter, this is used for simplifying the
30 registration and management of the registered filters.
32 2009-10-23 - r20356 - lavfi 1.4.1 - AVFilter.description
33 Add a description field to AVFilter.
35 2009-10-19 - r20302 - lavfi 1.3.0 - avfilter_make_format_list()
36 Change the interface of avfilter_make_format_list() from
37 avfilter_make_format_list(int n, ...) to
38 avfilter_make_format_list(enum PixelFormat *pix_fmts).
40 2009-10-18 - r20272 - lavfi 1.0.0 - avfilter_get_video_buffer()
41 Make avfilter_get_video_buffer() recursive and add the w and h
44 2009-10-07 - r20189 - lavfi 0.5.1 - AVFilterPic
45 Added w and h fields to AVFilterPic.
47 2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size
48 This is now an unsigned int instead of a signed int.
50 2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
51 Added a pts field to AVSubtitle which gives the subtitle's packet
52 PTS in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
53 not work right without this.
55 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
56 PKT_FLAG_KEY has been deprecated and will be dropped for the next
57 major version. Use AV_PKT_FLAG_KEY instead.
59 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
60 av_lockmgr_register() can be used to register a callback function
61 that lavc (and in the future, libraries that depend on lavc) can use
62 to implement mutexes. The application should provide a callback function
63 the implements the AV_LOCK_* operations described in avcodec.h.
64 When the lock manager is registered FFmpeg is guaranteed to behave
65 correct also in a multi-threaded application.
67 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet
68 av_free_packet() is no longer an inline function. It is now exported.
70 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree
71 Please use NULL instead. This has been supported since r16506
72 (lavf > 52.23.1, lavc > 52.10.0).
74 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
75 The old decoding functions are deprecated, all new code should use the
76 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
77 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
78 argument instead of a const uint8_t *buf / int buf_size pair.
80 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space
81 Introduce the av_fifo_space() function.
83 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
84 Move AVPacket declaration from libavformat/avformat.h to
87 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
88 Make the pixel formats: PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
89 PIX_FMT_BGRA, which were defined as macros, defined as enum
90 PixelFormat values, and viceversa make PIX_FMT_RGB32,
91 PIX_FMT_RGB32_1, PIX_FMT_BGR32, PIX_FMT_BGR32_1 defined as macros.
92 Also make avcodec_get_pix_fmt() recognize the "rgb32" and "bgr32"
94 Re-sort the enum PixelFormat list accordingly.
95 This change breaks API/ABI backward compatibility.
97 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
98 Add the enum PixelFormat values:
99 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
100 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
102 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
103 The Mersenne Twister PRNG implemented through the av_random* functions
104 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
107 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
108 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
109 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
110 and av_fifo_realloc2.
111 In addition, the order of the function arguments of av_fifo_generic_read
112 were changed to match av_fifo_generic_write.
113 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
114 applications, they may not use sizeof() or directly access members.
116 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
117 Introduce a new metadata API (see av_metadata_get() and friends).
118 The old API is now deprecated and should not be used anymore. This especially
119 includes the following structure fields:
120 - AVFormatContext.title
121 - AVFormatContext.author
122 - AVFormatContext.copyright
123 - AVFormatContext.comment
124 - AVFormatContext.album
125 - AVFormatContext.year
126 - AVFormatContext.track
127 - AVFormatContext.genre
130 - AVProgram.provider_name
