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 58.7.100 - avformat.h
19 Add url field to AVFormatContext and add ff_format_set_url helper function.
21 2018-01-xx - xxxxxxx - lavf 58.6.100 - avformat.h
22 Add AVFMTCTX_UNSEEKABLE (for HLS demuxer).
24 2018-xx-xx - xxxxxxx - lavu 56.9.100 - aes_ctr.h
25 Add method to set the 16-byte IV.
27 2018-01-xx - xxxxxxx - lavf 58.5.100 - avformat.h
28 Explicitly make avformat_network_init() and avformat_network_deinit() optional.
29 If these are not called, network initialization and deinitialization is
30 automatic, and unlike in older versions, fully supported, unless libavformat
31 is linked to ancient GnuTLS and OpenSSL.
33 2018-01-xx - xxxxxxx - lavf 58.4.100 - avformat.h
34 Deprecate AVStream.recommended_encoder_configuration. It was useful only for
35 FFserver, which has been removed.
37 2018-01-xx - xxxxxxx - lavfi 7.11.101 - avfilter.h
38 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
40 2017-xx-xx - xxxxxxx - lavr 4.0.0 - avresample.h
41 Deprecate the entire library. Merged years ago to provide compatibility
42 with Libav, it remained unmaintained by the FFmpeg project and duplicated
43 functionality provided by libswresample.
45 In order to improve consistency and reduce attack surface, it has been deprecated.
46 Users of this library are asked to migrate to libswresample, which, as well as
47 providing more functionality, is faster and has higher accuracy.
49 2017-xx-xx - xxxxxxx - lavc 58.9.100 - avcodec.h
50 Deprecate av_lockmgr_register(). You need to build FFmpeg with threading
51 support enabled to get basic thread-safety (which is the default build
54 2017-12-xx - xxxxxxx - lavu 56.7.100 - cpu.h

75 Deprecate user visibility of the AVHWAccel structure and the functions
76 av_register_hwaccel() and av_hwaccel_next().
78 2017-11-xx - xxxxxxx - lavc 58.4.100 - avcodec.h
79 Add AVCodecHWConfig and avcodec_get_hw_config().
81 2017-11-22 - 3650cb2dfa - lavu 55.3.100 - opencl.h

108 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
109 (avcodec_send_packet/avcodec_receive_frame) always work with reference
112 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
113 Add av_color_range_from_name(), av_color_primaries_from_name(),

388 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
390 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
391 compatible with lavfi>=6.47.100. Potentially also affects other users of
392 libavfilter if they are using one of the affected fields.

457 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
458 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
459 the reset of the ASS ReadOrder field on flush. This affects the content of
460 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
463 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
464 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
465 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
466 The default value for this option will change to "ass" at the next major
467 libavcodec version bump.
469 The current default is "ass_with_timings" for compatibility. This means that
470 all subtitles text decoders currently still output ASS with timings printed
471 as strings in the AVSubtitles.rects[N]->ass fields.
473 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
474 timing is limited to a 1/100 time base, so this is relevant for any subtitles
475 format needing a bigger one), ease timing adjustments, and prevents the need
476 of removing the timing from the decoded string yourself. This form is also
477 known as "the Matroska form". The timing information (start time, duration)
478 can be found in the AVSubtitles fields.

2883 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2884 Change the signature of avfilter_register() to make it return an
2885 int. This is required since now the registration operation may fail.
2887 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2888 Make the pixdesc.h API public.

2912 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2913 Add a pts field to AVSubtitle which gives the subtitle packet pts
2914 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2915 not work right without this.
2917 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2918 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2919 major version. Use AV_PKT_FLAG_KEY instead.
2921 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2922 av_lockmgr_register() can be used to register a callback function
2923 that lavc (and in the future, libraries that depend on lavc) can use
2924 to implement mutexes. The application should provide a callback function
2925 that implements the AV_LOCK_* operations described in avcodec.h.
2926 When the lock manager is registered, FFmpeg is guaranteed to behave
2927 correctly in a multi-threaded application.
2929 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2930 av_free_packet() is no longer an inline function. It is now exported.
2932 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2933 Please use NULL instead. This has been supported since r16506
2934 (lavf > 52.23.1, lavc > 52.10.0).
2936 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2937 The old decoding functions are deprecated, all new code should use the
2938 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2939 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2940 argument instead of a const uint8_t *buf / int buf_size pair.
2942 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2943 Introduce the av_fifo_space() function.

2946 Move AVPacket declaration from libavformat/avformat.h to
2947 libavcodec/avcodec.h.
2949 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2950 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2951 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2952 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2953 PIX_FMT_BGR32_1 are now macros.
2954 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2955 Re-sort the enum PixelFormat list accordingly.
2956 This change breaks API/ABI backward compatibility.
2958 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2959 Add the enum PixelFormat values:
2960 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2961 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2963 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2964 The Mersenne Twister PRNG implemented through the av_random* functions
2965 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2968 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2969 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2970 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2971 and av_fifo_realloc2.
2972 In addition, the order of the function arguments of av_fifo_generic_read
2973 was changed to match av_fifo_generic_write.
2974 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2975 applications, they may not use sizeof() or directly access members.
2977 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2978 Introduce a new metadata API (see av_metadata_get() and friends).
2979 The old API is now deprecated and should not be used anymore. This especially
2980 includes the following structure fields:
2981 - AVFormatContext.title
2982 - AVFormatContext.author
2983 - AVFormatContext.copyright
2984 - AVFormatContext.comment
2985 - AVFormatContext.album
2986 - AVFormatContext.year
2987 - AVFormatContext.track
2988 - AVFormatContext.genre
2991 - AVProgram.provider_name
