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-xx-xx - xxxxxxx - lavu 56.9.100 - aes_ctr.h
19 Add method to set the 16-byte IV.
21 2018-01-xx - xxxxxxx - lavf 58.5.100 - avformat.h
22 Explicitly make avformat_network_init() and avformat_network_deinit() optional.
23 If these are not called, network initialization and deinitialization is
24 automatic, and unlike in older versions, fully supported, unless libavformat
25 is linked to ancient GnuTLS and OpenSSL.
27 2018-01-xx - xxxxxxx - lavf 58.4.100 - avformat.h
28 Deprecate AVStream.recommended_encoder_configuration. It was useful only for
29 FFserver, which has been removed.
31 2018-01-xx - xxxxxxx - lavfi 7.11.101 - avfilter.h
32 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
34 2017-xx-xx - xxxxxxx - lavr 4.0.0 - avresample.h
35 Deprecate the entire library. Merged years ago to provide compatibility
36 with Libav, it remained unmaintained by the FFmpeg project and duplicated
37 functionality provided by libswresample.
39 In order to improve consistency and reduce attack surface, it has been deprecated.
40 Users of this library are asked to migrate to libswresample, which, as well as
41 providing more functionality, is faster and has higher accuracy.
43 2017-xx-xx - xxxxxxx - lavc 58.9.100 - avcodec.h
44 Deprecate av_lockmgr_register(). You need to build FFmpeg with threading
45 support enabled to get basic thread-safety (which is the default build
48 2017-12-xx - xxxxxxx - lavu 56.7.100 - cpu.h
51 2017-xx-xx - xxxxxxx - lavc 58.8.100 - avcodec.h
52 The MediaCodec decoders now support AVCodecContext.hw_device_ctx.
54 2017-xx-xx - xxxxxxx - lavu 56.6.100 - hwcontext.h hwcontext_mediacodec.h
55 Add AV_HWDEVICE_TYPE_MEDIACODEC and a new installed header with

66 Add const to AVCodecContext.hwaccel.
68 2017-11-xx - xxxxxxx - lavc 58.5.100 - avcodec.h
69 Deprecate user visibility of the AVHWAccel structure and the functions
70 av_register_hwaccel() and av_hwaccel_next().
72 2017-11-xx - xxxxxxx - lavc 58.4.100 - avcodec.h
73 Add AVCodecHWConfig and avcodec_get_hw_config().
75 2017-11-22 - 3650cb2dfa - lavu 55.3.100 - opencl.h
76 Remove experimental OpenCL API (av_opencl_*).
78 2017-11-22 - b25d8ef0a7 - lavu 55.2.100 - hwcontext.h hwcontext_opencl.h

101 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated
102 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
103 (avcodec_send_packet/avcodec_receive_frame) always work with reference
106 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
107 Add av_color_range_from_name(), av_color_primaries_from_name(),
108 av_color_transfer_from_name(), av_color_space_from_name(), and

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

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

381 Fix accidental ABI breakage in AVFilterContext.
382 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
384 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
385 compatible with lavfi>=6.47.100. Potentially also affects other users of

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

2911 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2912 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2913 major version. Use AV_PKT_FLAG_KEY instead.
2915 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2916 av_lockmgr_register() can be used to register a callback function
2917 that lavc (and in the future, libraries that depend on lavc) can use
2918 to implement mutexes. The application should provide a callback function
2919 that implements the AV_LOCK_* operations described in avcodec.h.
2920 When the lock manager is registered, FFmpeg is guaranteed to behave
2921 correctly in a multi-threaded application.
2923 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2924 av_free_packet() is no longer an inline function. It is now exported.
2926 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2927 Please use NULL instead. This has been supported since r16506
2928 (lavf > 52.23.1, lavc > 52.10.0).
2930 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2931 The old decoding functions are deprecated, all new code should use the
2932 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2933 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2934 argument instead of a const uint8_t *buf / int buf_size pair.
2936 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2937 Introduce the av_fifo_space() function.

2941 libavcodec/avcodec.h.
2943 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2944 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2945 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2946 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2947 PIX_FMT_BGR32_1 are now macros.
2948 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2949 Re-sort the enum PixelFormat list accordingly.
2950 This change breaks API/ABI backward compatibility.
2952 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2953 Add the enum PixelFormat values:

2955 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2957 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2958 The Mersenne Twister PRNG implemented through the av_random* functions
2959 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2962 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2963 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2964 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2965 and av_fifo_realloc2.
2966 In addition, the order of the function arguments of av_fifo_generic_read
2967 was changed to match av_fifo_generic_write.
2968 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2969 applications, they may not use sizeof() or directly access members.
2971 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2972 Introduce a new metadata API (see av_metadata_get() and friends).
2973 The old API is now deprecated and should not be used anymore. This especially
2974 includes the following structure fields:
2975 - AVFormatContext.title
2976 - AVFormatContext.author
2977 - AVFormatContext.copyright
2978 - AVFormatContext.comment
2979 - AVFormatContext.album
2980 - AVFormatContext.year
2981 - AVFormatContext.track
2982 - AVFormatContext.genre
2985 - AVProgram.provider_name
