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 58.6.100 - avformat.h
19 Add AVFMTCTX_UNSEEKABLE (for HLS demuxer).
21 2018-xx-xx - xxxxxxx - lavu 56.9.100 - aes_ctr.h
22 Add method to set the 16-byte IV.
24 2018-01-xx - xxxxxxx - lavf 58.5.100 - avformat.h
25 Explicitly make avformat_network_init() and avformat_network_deinit() optional.
26 If these are not called, network initialization and deinitialization is
27 automatic, and unlike in older versions, fully supported, unless libavformat
28 is linked to ancient GnuTLS and OpenSSL.
30 2018-01-xx - xxxxxxx - lavf 58.4.100 - avformat.h
31 Deprecate AVStream.recommended_encoder_configuration. It was useful only for
32 FFserver, which has been removed.
34 2018-01-xx - xxxxxxx - lavfi 7.11.101 - avfilter.h
35 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
37 2017-xx-xx - xxxxxxx - lavr 4.0.0 - avresample.h
38 Deprecate the entire library. Merged years ago to provide compatibility
39 with Libav, it remained unmaintained by the FFmpeg project and duplicated
40 functionality provided by libswresample.
42 In order to improve consistency and reduce attack surface, it has been deprecated.
43 Users of this library are asked to migrate to libswresample, which, as well as
44 providing more functionality, is faster and has higher accuracy.
46 2017-xx-xx - xxxxxxx - lavc 58.9.100 - avcodec.h
47 Deprecate av_lockmgr_register(). You need to build FFmpeg with threading
48 support enabled to get basic thread-safety (which is the default build
51 2017-12-xx - xxxxxxx - lavu 56.7.100 - cpu.h
54 2017-xx-xx - xxxxxxx - lavc 58.8.100 - avcodec.h

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

105 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
106 (avcodec_send_packet/avcodec_receive_frame) always work with reference
109 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
110 Add av_color_range_from_name(), av_color_primaries_from_name(),
111 av_color_transfer_from_name(), av_color_space_from_name(), and

220 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
221 (via an entry named "rotate"). Use av_stream_get_side_data() with
222 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with

330 Decoders now export the frame timestamp as AVFrame.pts. It was
331 previously exported as AVFrame.pkt_pts, which is now deprecated.
333 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
334 and not the codec timebase.

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

454 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
455 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
456 the reset of the ASS ReadOrder field on flush. This affects the content of
457 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
460 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
461 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
462 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
463 The default value for this option will change to "ass" at the next major
464 libavcodec version bump.
466 The current default is "ass_with_timings" for compatibility. This means that
467 all subtitles text decoders currently still output ASS with timings printed
468 as strings in the AVSubtitles.rects[N]->ass fields.
470 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
471 timing is limited to a 1/100 time base, so this is relevant for any subtitles
472 format needing a bigger one), ease timing adjustments, and prevents the need
473 of removing the timing from the decoded string yourself. This form is also
474 known as "the Matroska form". The timing information (start time, duration)
475 can be found in the AVSubtitles fields.

2914 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2915 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2916 major version. Use AV_PKT_FLAG_KEY instead.
2918 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2919 av_lockmgr_register() can be used to register a callback function
2920 that lavc (and in the future, libraries that depend on lavc) can use
2921 to implement mutexes. The application should provide a callback function
2922 that implements the AV_LOCK_* operations described in avcodec.h.
2923 When the lock manager is registered, FFmpeg is guaranteed to behave
2924 correctly in a multi-threaded application.
2926 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2927 av_free_packet() is no longer an inline function. It is now exported.
2929 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2930 Please use NULL instead. This has been supported since r16506
2931 (lavf > 52.23.1, lavc > 52.10.0).
2933 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2934 The old decoding functions are deprecated, all new code should use the
2935 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2936 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2937 argument instead of a const uint8_t *buf / int buf_size pair.
2939 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2940 Introduce the av_fifo_space() function.

2944 libavcodec/avcodec.h.
2946 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2947 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2948 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2949 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2950 PIX_FMT_BGR32_1 are now macros.
2951 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2952 Re-sort the enum PixelFormat list accordingly.
2953 This change breaks API/ABI backward compatibility.
2955 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2956 Add the enum PixelFormat values:

2958 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2960 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2961 The Mersenne Twister PRNG implemented through the av_random* functions
2962 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2965 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2966 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2967 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2968 and av_fifo_realloc2.
2969 In addition, the order of the function arguments of av_fifo_generic_read
2970 was changed to match av_fifo_generic_write.
2971 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2972 applications, they may not use sizeof() or directly access members.
2974 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2975 Introduce a new metadata API (see av_metadata_get() and friends).
2976 The old API is now deprecated and should not be used anymore. This especially
2977 includes the following structure fields:
2978 - AVFormatContext.title
2979 - AVFormatContext.author
2980 - AVFormatContext.copyright
2981 - AVFormatContext.comment
2982 - AVFormatContext.album
2983 - AVFormatContext.year
2984 - AVFormatContext.track
2985 - AVFormatContext.genre
2988 - AVProgram.provider_name
