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 2018-01-xx - xxxxxxx - lavf 58.4.100 - avformat.h
19 Deprecate AVStream.recommended_encoder_configuration. It was useful only for
20 FFserver, which has been removed.
22 2018-01-xx - xxxxxxx - lavfi 7.11.101 - avfilter.h
23 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
25 2017-xx-xx - xxxxxxx - lavr 4.0.0 - avresample.h
26 Deprecate the entire library. Merged years ago to provide compatibility
27 with Libav, it remained unmaintained by the FFmpeg project and duplicated
28 functionality provided by libswresample.
30 In order to improve consistency and reduce attack surface, it has been deprecated.
31 Users of this library are asked to migrate to libswresample, which, as well as
32 providing more functionality, is faster and has higher accuracy.
34 2017-xx-xx - xxxxxxx - lavc 58.9.100 - avcodec.h
35 Deprecate av_lockmgr_register(). You need to build FFmpeg with threading
36 support enabled to get basic thread-safety (which is the default build

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

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

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

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

2902 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2903 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2904 major version. Use AV_PKT_FLAG_KEY instead.
2906 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2907 av_lockmgr_register() can be used to register a callback function
2908 that lavc (and in the future, libraries that depend on lavc) can use
2909 to implement mutexes. The application should provide a callback function
2910 that implements the AV_LOCK_* operations described in avcodec.h.
2911 When the lock manager is registered, FFmpeg is guaranteed to behave
2912 correctly in a multi-threaded application.
2914 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2915 av_free_packet() is no longer an inline function. It is now exported.
2917 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2918 Please use NULL instead. This has been supported since r16506
2919 (lavf > 52.23.1, lavc > 52.10.0).
2921 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2922 The old decoding functions are deprecated, all new code should use the
2923 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2924 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2925 argument instead of a const uint8_t *buf / int buf_size pair.
2927 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2928 Introduce the av_fifo_space() function.

2932 libavcodec/avcodec.h.
2934 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2935 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2936 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2937 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2938 PIX_FMT_BGR32_1 are now macros.
2939 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2940 Re-sort the enum PixelFormat list accordingly.
2941 This change breaks API/ABI backward compatibility.
2943 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2944 Add the enum PixelFormat values:
2945 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2946 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2948 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2949 The Mersenne Twister PRNG implemented through the av_random* functions
2950 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2953 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2954 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2955 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2956 and av_fifo_realloc2.
2957 In addition, the order of the function arguments of av_fifo_generic_read
2958 was changed to match av_fifo_generic_write.
2959 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2960 applications, they may not use sizeof() or directly access members.
2962 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2963 Introduce a new metadata API (see av_metadata_get() and friends).
2964 The old API is now deprecated and should not be used anymore. This especially
2965 includes the following structure fields:
2966 - AVFormatContext.title
2967 - AVFormatContext.author
2968 - AVFormatContext.copyright
2969 - AVFormatContext.comment
2970 - AVFormatContext.album
2971 - AVFormatContext.year
2972 - AVFormatContext.track
2973 - AVFormatContext.genre
2976 - AVProgram.provider_name
