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

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

315 Decoders now export the frame timestamp as AVFrame.pts. It was
316 previously exported as AVFrame.pkt_pts, which is now deprecated.
318 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
319 and not the codec timebase.

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

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

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

2865 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2866 Change the signature of avfilter_register() to make it return an
2867 int. This is required since now the registration operation may fail.
2869 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2870 Make the pixdesc.h API public.

2894 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2895 Add a pts field to AVSubtitle which gives the subtitle packet pts
2896 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2897 not work right without this.
2899 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2900 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2901 major version. Use AV_PKT_FLAG_KEY instead.
2903 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2904 av_lockmgr_register() can be used to register a callback function
2905 that lavc (and in the future, libraries that depend on lavc) can use
2906 to implement mutexes. The application should provide a callback function
2907 that implements the AV_LOCK_* operations described in avcodec.h.
2908 When the lock manager is registered, FFmpeg is guaranteed to behave
2909 correctly in a multi-threaded application.
2911 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2912 av_free_packet() is no longer an inline function. It is now exported.
2914 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2915 Please use NULL instead. This has been supported since r16506
2916 (lavf > 52.23.1, lavc > 52.10.0).
2918 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2919 The old decoding functions are deprecated, all new code should use the
2920 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2921 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2922 argument instead of a const uint8_t *buf / int buf_size pair.
2924 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2925 Introduce the av_fifo_space() function.

2929 libavcodec/avcodec.h.
2931 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2932 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2933 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2934 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2935 PIX_FMT_BGR32_1 are now macros.
2936 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2937 Re-sort the enum PixelFormat list accordingly.
2938 This change breaks API/ABI backward compatibility.
2940 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2941 Add the enum PixelFormat values:
2942 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2943 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2945 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2946 The Mersenne Twister PRNG implemented through the av_random* functions
2947 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2950 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2951 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2952 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2953 and av_fifo_realloc2.
2954 In addition, the order of the function arguments of av_fifo_generic_read
2955 was changed to match av_fifo_generic_write.
2956 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2957 applications, they may not use sizeof() or directly access members.
2959 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2960 Introduce a new metadata API (see av_metadata_get() and friends).
2961 The old API is now deprecated and should not be used anymore. This especially
2962 includes the following structure fields:
2963 - AVFormatContext.title
2964 - AVFormatContext.author
2965 - AVFormatContext.copyright
2966 - AVFormatContext.comment
2967 - AVFormatContext.album
2968 - AVFormatContext.year
2969 - AVFormatContext.track
2970 - AVFormatContext.genre
2973 - AVProgram.provider_name
