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

62 2017-xx-xx - xxxxxxx - lavc 58.6.100 - avcodec.h
63 Add const to AVCodecContext.hwaccel.
65 2017-11-xx - xxxxxxx - lavc 58.5.100 - avcodec.h
66 Deprecate user visibility of the AVHWAccel structure and the functions
67 av_register_hwaccel() and av_hwaccel_next().
69 2017-11-xx - xxxxxxx - lavc 58.4.100 - avcodec.h
70 Add AVCodecHWConfig and avcodec_get_hw_config().
72 2017-11-22 - 3650cb2dfa - lavu 55.3.100 - opencl.h
73 Remove experimental OpenCL API (av_opencl_*).
75 2017-11-22 - b25d8ef0a7 - lavu 55.2.100 - hwcontext.h hwcontext_opencl.h
76 Add AV_HWDEVICE_TYPE_OPENCL and a new installed header with

97 2017-09-26 - b1cf151c4d - lavc 57.106.102 - avcodec.h
98 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated
99 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
100 (avcodec_send_packet/avcodec_receive_frame) always work with reference
103 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
104 Add av_color_range_from_name(), av_color_primaries_from_name(),
105 av_color_transfer_from_name(), av_color_space_from_name(), and

213 2017-03-27 - ddef3d902f - lavf 57.68.100 - avformat.h
214 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
215 (via an entry named "rotate"). Use av_stream_get_side_data() with
216 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with

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

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

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

2874 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2875 Change the signature of avfilter_register() to make it return an
2876 int. This is required since now the registration operation may fail.
2878 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2879 Make the pixdesc.h API public.

2908 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2909 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2910 major version. Use AV_PKT_FLAG_KEY instead.
2912 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2913 av_lockmgr_register() can be used to register a callback function
2914 that lavc (and in the future, libraries that depend on lavc) can use
2915 to implement mutexes. The application should provide a callback function
2916 that implements the AV_LOCK_* operations described in avcodec.h.
2917 When the lock manager is registered, FFmpeg is guaranteed to behave
2918 correctly in a multi-threaded application.
2920 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2921 av_free_packet() is no longer an inline function. It is now exported.
2923 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2924 Please use NULL instead. This has been supported since r16506
2925 (lavf > 52.23.1, lavc > 52.10.0).
2927 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2928 The old decoding functions are deprecated, all new code should use the
2929 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2930 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2931 argument instead of a const uint8_t *buf / int buf_size pair.
2933 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2934 Introduce the av_fifo_space() function.

2938 libavcodec/avcodec.h.
2940 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2941 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2942 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2943 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2944 PIX_FMT_BGR32_1 are now macros.
2945 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2946 Re-sort the enum PixelFormat list accordingly.
2947 This change breaks API/ABI backward compatibility.
2949 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2950 Add the enum PixelFormat values:
2951 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2952 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2954 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2955 The Mersenne Twister PRNG implemented through the av_random* functions
2956 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2959 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2960 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2961 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2962 and av_fifo_realloc2.
2963 In addition, the order of the function arguments of av_fifo_generic_read
2964 was changed to match av_fifo_generic_write.
2965 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2966 applications, they may not use sizeof() or directly access members.
2968 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2969 Introduce a new metadata API (see av_metadata_get() and friends).
2970 The old API is now deprecated and should not be used anymore. This especially
2971 includes the following structure fields:
2972 - AVFormatContext.title
2973 - AVFormatContext.author
2974 - AVFormatContext.copyright
2975 - AVFormatContext.comment
2976 - AVFormatContext.album
2977 - AVFormatContext.year
2978 - AVFormatContext.track
2979 - AVFormatContext.genre
2982 - AVProgram.provider_name
