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
10 libpostproc: 2017-10-21
11 libswresample: 2017-10-21
12 libswscale: 2017-10-21
16 API changes, most recent first:
18 2017-xx-xx - xxxxxxx - lavr 4.0.0 - avresample.h
19 Deprecate the entire library. Merged years ago to provide compatibility
20 with Libav, it remained unmaintained by the FFmpeg project and duplicated
21 functionality provided by libswresample.
23 In order to improve consistency and reduce attack surface, it has been deprecated.
24 Users of this library are asked to migrate to libswresample, which, as well as
25 providing more functionality, is faster and has higher accuracy.

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

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

436 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
437 the reset of the ASS ReadOrder field on flush. This affects the content of
438 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
441 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
442 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
443 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
444 The default value for this option will change to "ass" at the next major
445 libavcodec version bump.
447 The current default is "ass_with_timings" for compatibility. This means that
448 all subtitles text decoders currently still output ASS with timings printed
449 as strings in the AVSubtitles.rects[N]->ass fields.
451 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
452 timing is limited to a 1/100 time base, so this is relevant for any subtitles
453 format needing a bigger one), ease timing adjustments, and prevents the need
454 of removing the timing from the decoded string yourself. This form is also
455 known as "the Matroska form". The timing information (start time, duration)
456 can be found in the AVSubtitles fields.

2861 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2862 Change the signature of avfilter_register() to make it return an
2863 int. This is required since now the registration operation may fail.
2865 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2866 Make the pixdesc.h API public.

2895 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2896 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2897 major version. Use AV_PKT_FLAG_KEY instead.
2899 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2900 av_lockmgr_register() can be used to register a callback function
2901 that lavc (and in the future, libraries that depend on lavc) can use
2902 to implement mutexes. The application should provide a callback function
2903 that implements the AV_LOCK_* operations described in avcodec.h.
2904 When the lock manager is registered, FFmpeg is guaranteed to behave
2905 correctly in a multi-threaded application.
2907 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2908 av_free_packet() is no longer an inline function. It is now exported.
2910 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2911 Please use NULL instead. This has been supported since r16506
2912 (lavf > 52.23.1, lavc > 52.10.0).
2914 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2915 The old decoding functions are deprecated, all new code should use the
2916 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2917 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2918 argument instead of a const uint8_t *buf / int buf_size pair.
2920 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2921 Introduce the av_fifo_space() function.

2928 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2929 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2930 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2931 PIX_FMT_BGR32_1 are now macros.
2932 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2933 Re-sort the enum PixelFormat list accordingly.
2934 This change breaks API/ABI backward compatibility.
2936 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2937 Add the enum PixelFormat values:
2938 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2939 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2941 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2942 The Mersenne Twister PRNG implemented through the av_random* functions
2943 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2946 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2947 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2948 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2949 and av_fifo_realloc2.
2950 In addition, the order of the function arguments of av_fifo_generic_read
2951 was changed to match av_fifo_generic_write.
2952 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2953 applications, they may not use sizeof() or directly access members.
2955 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2956 Introduce a new metadata API (see av_metadata_get() and friends).
2957 The old API is now deprecated and should not be used anymore. This especially
2958 includes the following structure fields:
2959 - AVFormatContext.title
2960 - AVFormatContext.author
2961 - AVFormatContext.copyright
2962 - AVFormatContext.comment
2963 - AVFormatContext.album
2964 - AVFormatContext.year
2965 - AVFormatContext.track
2966 - AVFormatContext.genre
2969 - AVProgram.provider_name
