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 2018-02-xx - xxxxxxx - lavf 58.8.100 - avformat.h
19 Deprecate the current names of the RTSP "timeout", "stimeout", "user-agent"
20 options. Introduce "listen_timeout" as replacement for the current "timeout"
21 option, and "user_agent" as replacement for "user-agent". Once the deprecation
22 is over, the old "timeout" option will be removed, and "stimeout" will be
23 renamed to "stimeout" (the "timeout" option will essentially change semantics).
25 2018-01-xx - xxxxxxx - lavf 58.7.100 - avformat.h
26 Deprecate AVFormatContext filename field which had limited length, use the
27 new dynamically allocated url field instead.
29 2018-01-xx - xxxxxxx - lavf 58.7.100 - avformat.h
30 Add url field to AVFormatContext and add ff_format_set_url helper function.
32 2018-01-xx - xxxxxxx - lavf 58.6.100 - avformat.h
33 Add AVFMTCTX_UNSEEKABLE (for HLS demuxer).
35 2018-xx-xx - xxxxxxx - lavu 56.9.100 - aes_ctr.h
36 Add method to set the 16-byte IV.
38 2018-01-xx - xxxxxxx - lavf 58.5.100 - avformat.h
39 Explicitly make avformat_network_init() and avformat_network_deinit() optional.
40 If these are not called, network initialization and deinitialization is
41 automatic, and unlike in older versions, fully supported, unless libavformat
42 is linked to ancient GnuTLS and OpenSSL.
44 2018-01-xx - xxxxxxx - lavf 58.4.100 - avformat.h
45 Deprecate AVStream.recommended_encoder_configuration. It was useful only for
46 FFserver, which has been removed.
48 2018-01-xx - xxxxxxx - lavfi 7.11.101 - avfilter.h
49 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
51 2017-xx-xx - xxxxxxx - lavr 4.0.0 - avresample.h
52 Deprecate the entire library. Merged years ago to provide compatibility
53 with Libav, it remained unmaintained by the FFmpeg project and duplicated
54 functionality provided by libswresample.
56 In order to improve consistency and reduce attack surface, it has been deprecated.
57 Users of this library are asked to migrate to libswresample, which, as well as
58 providing more functionality, is faster and has higher accuracy.
60 2017-xx-xx - xxxxxxx - lavc 58.9.100 - avcodec.h
61 Deprecate av_lockmgr_register(). You need to build FFmpeg with threading
62 support enabled to get basic thread-safety (which is the default build
65 2017-12-xx - xxxxxxx - lavu 56.7.100 - cpu.h
68 2017-xx-xx - xxxxxxx - lavc 58.8.100 - avcodec.h

71 2017-xx-xx - xxxxxxx - lavu 56.6.100 - hwcontext.h hwcontext_mediacodec.h
72 Add AV_HWDEVICE_TYPE_MEDIACODEC and a new installed header with
73 MediaCodec-specific hwcontext definitions.
75 2017-xx-xx - xxxxxxc - lavc 58.7.100 - avcodec.h
76 Add AV_CODEC_CAP_HARDWARE, AV_CODEC_CAP_HYBRID, and AVCodec.wrapper_name,
77 and mark all AVCodecs accordingly.

119 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
120 (avcodec_send_packet/avcodec_receive_frame) always work with reference
123 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
124 Add av_color_range_from_name(), av_color_primaries_from_name(),
125 av_color_transfer_from_name(), av_color_space_from_name(), and

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

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

2929 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2930 major version. Use AV_PKT_FLAG_KEY instead.
2932 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2933 av_lockmgr_register() can be used to register a callback function
2934 that lavc (and in the future, libraries that depend on lavc) can use
2935 to implement mutexes. The application should provide a callback function
2936 that implements the AV_LOCK_* operations described in avcodec.h.
2937 When the lock manager is registered, FFmpeg is guaranteed to behave
2938 correctly in a multi-threaded application.
2940 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2941 av_free_packet() is no longer an inline function. It is now exported.
2943 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2944 Please use NULL instead. This has been supported since r16506
2945 (lavf > 52.23.1, lavc > 52.10.0).
2947 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2948 The old decoding functions are deprecated, all new code should use the
2949 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2950 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2951 argument instead of a const uint8_t *buf / int buf_size pair.
2953 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2954 Introduce the av_fifo_space() function.

2958 libavcodec/avcodec.h.
2960 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2961 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2962 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2963 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2964 PIX_FMT_BGR32_1 are now macros.
2965 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2966 Re-sort the enum PixelFormat list accordingly.
2967 This change breaks API/ABI backward compatibility.
2969 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2970 Add the enum PixelFormat values:
2971 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2972 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2974 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2975 The Mersenne Twister PRNG implemented through the av_random* functions
2976 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2979 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2980 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2981 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2982 and av_fifo_realloc2.
2983 In addition, the order of the function arguments of av_fifo_generic_read
2984 was changed to match av_fifo_generic_write.
2985 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2986 applications, they may not use sizeof() or directly access members.
2988 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2989 Introduce a new metadata API (see av_metadata_get() and friends).
2990 The old API is now deprecated and should not be used anymore. This especially
2991 includes the following structure fields:
2992 - AVFormatContext.title
2993 - AVFormatContext.author
2994 - AVFormatContext.copyright
2995 - AVFormatContext.comment
2996 - AVFormatContext.album
2997 - AVFormatContext.year
2998 - AVFormatContext.track
2999 - AVFormatContext.genre
3002 - AVProgram.provider_name
