1 Never assume the API of libav* to be stable unless at least 1 month has passed
2 since the last major version increase or the API was added.
4 The last version increases were:
6 libavdevice: 2017-10-21
7 libavfilter: 2017-10-21
8 libavformat: 2017-10-21
9 libavresample: 2017-10-21

16 API changes, most recent first:
18 2018-01-xx - xxxxxxx - lavfi 7.11.101 - avfilter.h
19 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
21 2017-xx-xx - xxxxxxx - lavr 4.0.0 - avresample.h
22 Deprecate the entire library. Merged years ago to provide compatibility
23 with Libav, it remained unmaintained by the FFmpeg project and duplicated
24 functionality provided by libswresample.
26 In order to improve consistency and reduce attack surface, it has been deprecated.
27 Users of this library are asked to migrate to libswresample, which, as well as
28 providing more functionality, is faster and has higher accuracy.

204 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
205 (via an entry named "rotate"). Use av_stream_get_side_data() with
206 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
207 av_display_rotation_get(). The same is done for muxing. Instead of adding a
208 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has

368 Fix accidental ABI breakage in AVFilterContext.
369 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
371 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
372 compatible with lavfi>=6.47.100. Potentially also affects other users of
373 libavfilter if they are using one of the affected fields.

439 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
440 the reset of the ASS ReadOrder field on flush. This affects the content of

444 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
445 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
446 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
447 The default value for this option will change to "ass" at the next major
448 libavcodec version bump.
450 The current default is "ass_with_timings" for compatibility. This means that
451 all subtitles text decoders currently still output ASS with timings printed
452 as strings in the AVSubtitles.rects[N]->ass fields.
454 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
455 timing is limited to a 1/100 time base, so this is relevant for any subtitles
456 format needing a bigger one), ease timing adjustments, and prevents the need
457 of removing the timing from the decoded string yourself. This form is also
458 known as "the Matroska form". The timing information (start time, duration)
459 can be found in the AVSubtitles fields.

2864 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2865 Change the signature of avfilter_register() to make it return an
2866 int. This is required since now the registration operation may fail.
2868 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2869 Make the pixdesc.h API public.

2893 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2894 Add a pts field to AVSubtitle which gives the subtitle packet pts
2895 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2896 not work right without this.
2898 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2899 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2900 major version. Use AV_PKT_FLAG_KEY instead.
2902 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2903 av_lockmgr_register() can be used to register a callback function
2904 that lavc (and in the future, libraries that depend on lavc) can use
2905 to implement mutexes. The application should provide a callback function
2906 that implements the AV_LOCK_* operations described in avcodec.h.
2907 When the lock manager is registered, FFmpeg is guaranteed to behave
2908 correctly in a multi-threaded application.
2910 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2911 av_free_packet() is no longer an inline function. It is now exported.
2913 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2914 Please use NULL instead. This has been supported since r16506
2915 (lavf > 52.23.1, lavc > 52.10.0).
2917 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2918 The old decoding functions are deprecated, all new code should use the
2919 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2920 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2921 argument instead of a const uint8_t *buf / int buf_size pair.
2923 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2924 Introduce the av_fifo_space() function.

2928 libavcodec/avcodec.h.
2930 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2931 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2932 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2933 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2934 PIX_FMT_BGR32_1 are now macros.
2935 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2936 Re-sort the enum PixelFormat list accordingly.
2937 This change breaks API/ABI backward compatibility.
2939 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2940 Add the enum PixelFormat values:
2941 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2942 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2944 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2945 The Mersenne Twister PRNG implemented through the av_random* functions
2946 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2949 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2950 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2951 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2952 and av_fifo_realloc2.
2953 In addition, the order of the function arguments of av_fifo_generic_read
2954 was changed to match av_fifo_generic_write.
2955 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2956 applications, they may not use sizeof() or directly access members.
2958 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2959 Introduce a new metadata API (see av_metadata_get() and friends).
2960 The old API is now deprecated and should not be used anymore. This especially
2961 includes the following structure fields:
2962 - AVFormatContext.title
2963 - AVFormatContext.author
2964 - AVFormatContext.copyright
2965 - AVFormatContext.comment
2966 - AVFormatContext.album
2967 - AVFormatContext.year
2968 - AVFormatContext.track
2969 - AVFormatContext.genre
2972 - AVProgram.provider_name
