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 Deprecate AVFormatContext filename field which had limited length, use the
20 new dynamically allocated url field instead.
22 2018-01-xx - xxxxxxx - lavf 58.7.100 - avformat.h
23 Add url field to AVFormatContext and add ff_format_set_url helper function.
25 2018-01-xx - xxxxxxx - lavf 58.6.100 - avformat.h
26 Add AVFMTCTX_UNSEEKABLE (for HLS demuxer).

29 Add method to set the 16-byte IV.
31 2018-01-xx - xxxxxxx - lavf 58.5.100 - avformat.h
32 Explicitly make avformat_network_init() and avformat_network_deinit() optional.
33 If these are not called, network initialization and deinitialization is
34 automatic, and unlike in older versions, fully supported, unless libavformat
35 is linked to ancient GnuTLS and OpenSSL.
37 2018-01-xx - xxxxxxx - lavf 58.4.100 - avformat.h
38 Deprecate AVStream.recommended_encoder_configuration. It was useful only for
39 FFserver, which has been removed.
41 2018-01-xx - xxxxxxx - lavfi 7.11.101 - avfilter.h
42 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
44 2017-xx-xx - xxxxxxx - lavr 4.0.0 - avresample.h
45 Deprecate the entire library. Merged years ago to provide compatibility
46 with Libav, it remained unmaintained by the FFmpeg project and duplicated
47 functionality provided by libswresample.
49 In order to improve consistency and reduce attack surface, it has been deprecated.
50 Users of this library are asked to migrate to libswresample, which, as well as
51 providing more functionality, is faster and has higher accuracy.
53 2017-xx-xx - xxxxxxx - lavc 58.9.100 - avcodec.h
54 Deprecate av_lockmgr_register(). You need to build FFmpeg with threading
55 support enabled to get basic thread-safety (which is the default build

113 (avcodec_send_packet/avcodec_receive_frame) always work with reference
116 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
117 Add av_color_range_from_name(), av_color_primaries_from_name(),

390 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
391 Fix accidental ABI breakage in AVFilterContext.
392 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
394 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
395 compatible with lavfi>=6.47.100. Potentially also affects other users of
396 libavfilter if they are using one of the affected fields.

449 Add requirement to bitstream filtering API that returned packets with
450 size == 0 and side_data_elems == 0 are to be skipped by the caller.
452 2016-03-04 - 9362973 - lavf 57.28.100

461 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
462 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
463 the reset of the ASS ReadOrder field on flush. This affects the content of
464 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
467 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
468 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
469 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
470 The default value for this option will change to "ass" at the next major
471 libavcodec version bump.
473 The current default is "ass_with_timings" for compatibility. This means that
474 all subtitles text decoders currently still output ASS with timings printed
475 as strings in the AVSubtitles.rects[N]->ass fields.
477 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
478 timing is limited to a 1/100 time base, so this is relevant for any subtitles
479 format needing a bigger one), ease timing adjustments, and prevents the need
480 of removing the timing from the decoded string yourself. This form is also
481 known as "the Matroska form". The timing information (start time, duration)
482 can be found in the AVSubtitles fields.

2921 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2922 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2923 major version. Use AV_PKT_FLAG_KEY instead.
2925 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2926 av_lockmgr_register() can be used to register a callback function
2927 that lavc (and in the future, libraries that depend on lavc) can use
2928 to implement mutexes. The application should provide a callback function
2929 that implements the AV_LOCK_* operations described in avcodec.h.
2930 When the lock manager is registered, FFmpeg is guaranteed to behave
2931 correctly in a multi-threaded application.
2933 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2934 av_free_packet() is no longer an inline function. It is now exported.
2936 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2937 Please use NULL instead. This has been supported since r16506
2938 (lavf > 52.23.1, lavc > 52.10.0).
2940 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2941 The old decoding functions are deprecated, all new code should use the
2942 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2943 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2944 argument instead of a const uint8_t *buf / int buf_size pair.
2946 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2947 Introduce the av_fifo_space() function.

2951 libavcodec/avcodec.h.
2953 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2954 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2955 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2956 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2957 PIX_FMT_BGR32_1 are now macros.
2958 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2959 Re-sort the enum PixelFormat list accordingly.
2960 This change breaks API/ABI backward compatibility.
2962 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2963 Add the enum PixelFormat values:

2965 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2967 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2968 The Mersenne Twister PRNG implemented through the av_random* functions
2969 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2972 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2973 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2974 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2975 and av_fifo_realloc2.
2976 In addition, the order of the function arguments of av_fifo_generic_read
2977 was changed to match av_fifo_generic_write.
2978 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2979 applications, they may not use sizeof() or directly access members.
2981 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2982 Introduce a new metadata API (see av_metadata_get() and friends).
2983 The old API is now deprecated and should not be used anymore. This especially
2984 includes the following structure fields:
2985 - AVFormatContext.title
2986 - AVFormatContext.author
2987 - AVFormatContext.copyright
2988 - AVFormatContext.comment
2989 - AVFormatContext.album
2990 - AVFormatContext.year
2991 - AVFormatContext.track
2992 - AVFormatContext.genre
2995 - AVProgram.provider_name
