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 2018-02-06 - 0fd475704e - lavd 58.1.100 - avdevice.h
19 Deprecate use of av_input_audio_device_next(), av_input_video_device_next(),
20 av_output_audio_device_next(), av_output_video_device_next().
21 Add av_indev_iterate(), and av_outdev_iterate().
23 2018-xx-xx - xxxxxxx - lavf 58.9.100 - avformat.h
24 Deprecate use of av_register_input_format(), av_register_output_format(),
25 av_register_all(), av_iformat_next(), av_oformat_next().
26 Add av_demuxer_iterate(), and av_muxer_iterate().
28 2018-xx-xx - xxxxxxx - lavc 58.10.100 - avcodec.h
29 Deprecate use of avcodec_register(), avcodec_register_all(),
30 av_codec_next(), av_register_codec_parser(), and av_parser_next().
31 Add av_codec_iterate() and av_parser_iterate().
33 2018-02-xx - xxxxxxx - lavf 58.8.100 - avformat.h
34 Deprecate the current names of the RTSP "timeout", "stimeout", "user-agent"
35 options. Introduce "listen_timeout" as replacement for the current "timeout"
36 option, and "user_agent" as replacement for "user-agent". Once the deprecation
37 is over, the old "timeout" option will be removed, and "stimeout" will be
38 renamed to "stimeout" (the "timeout" option will essentially change semantics).
40 2018-01-xx - xxxxxxx - lavf 58.7.100 - avformat.h
41 Deprecate AVFormatContext filename field which had limited length, use the
42 new dynamically allocated url field instead.
44 2018-01-xx - xxxxxxx - lavf 58.7.100 - avformat.h
45 Add url field to AVFormatContext and add ff_format_set_url helper function.
47 2018-01-xx - xxxxxxx - lavf 58.6.100 - avformat.h
48 Add AVFMTCTX_UNSEEKABLE (for HLS demuxer).
50 2018-xx-xx - xxxxxxx - lavu 56.9.100 - aes_ctr.h
51 Add method to set the 16-byte IV.
53 2018-01-xx - xxxxxxx - lavf 58.5.100 - avformat.h
54 Explicitly make avformat_network_init() and avformat_network_deinit() optional.
55 If these are not called, network initialization and deinitialization is
56 automatic, and unlike in older versions, fully supported, unless libavformat
57 is linked to ancient GnuTLS and OpenSSL.
59 2018-01-xx - xxxxxxx - lavf 58.4.100 - avformat.h
60 Deprecate AVStream.recommended_encoder_configuration. It was useful only for
61 FFserver, which has been removed.
63 2018-01-xx - xxxxxxx - lavfi 7.11.101 - avfilter.h
64 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
66 2017-xx-xx - xxxxxxx - lavr 4.0.0 - avresample.h
67 Deprecate the entire library. Merged years ago to provide compatibility
68 with Libav, it remained unmaintained by the FFmpeg project and duplicated
69 functionality provided by libswresample.
71 In order to improve consistency and reduce attack surface, it has been deprecated.
72 Users of this library are asked to migrate to libswresample, which, as well as
73 providing more functionality, is faster and has higher accuracy.
75 2017-xx-xx - xxxxxxx - lavc 58.9.100 - avcodec.h
76 Deprecate av_lockmgr_register(). You need to build FFmpeg with threading
77 support enabled to get basic thread-safety (which is the default build

134 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
135 (avcodec_send_packet/avcodec_receive_frame) always work with reference
138 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
139 Add av_color_range_from_name(), av_color_primaries_from_name(),

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

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

2943 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2944 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2945 major version. Use AV_PKT_FLAG_KEY instead.
2947 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2948 av_lockmgr_register() can be used to register a callback function
2949 that lavc (and in the future, libraries that depend on lavc) can use
2950 to implement mutexes. The application should provide a callback function
2951 that implements the AV_LOCK_* operations described in avcodec.h.
2952 When the lock manager is registered, FFmpeg is guaranteed to behave
2953 correctly in a multi-threaded application.
2955 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2956 av_free_packet() is no longer an inline function. It is now exported.
2958 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2959 Please use NULL instead. This has been supported since r16506
2960 (lavf > 52.23.1, lavc > 52.10.0).
2962 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2963 The old decoding functions are deprecated, all new code should use the
2964 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2965 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2966 argument instead of a const uint8_t *buf / int buf_size pair.
2968 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2969 Introduce the av_fifo_space() function.

2973 libavcodec/avcodec.h.
2975 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2976 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2977 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2978 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2979 PIX_FMT_BGR32_1 are now macros.
2980 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2981 Re-sort the enum PixelFormat list accordingly.
2982 This change breaks API/ABI backward compatibility.
2984 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2985 Add the enum PixelFormat values:

2987 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2989 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2990 The Mersenne Twister PRNG implemented through the av_random* functions
2991 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2994 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2995 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2996 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2997 and av_fifo_realloc2.
2998 In addition, the order of the function arguments of av_fifo_generic_read
2999 was changed to match av_fifo_generic_write.
3000 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3001 applications, they may not use sizeof() or directly access members.
3003 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3004 Introduce a new metadata API (see av_metadata_get() and friends).
3005 The old API is now deprecated and should not be used anymore. This especially
3006 includes the following structure fields:
3007 - AVFormatContext.title
3008 - AVFormatContext.author
3009 - AVFormatContext.copyright
3010 - AVFormatContext.comment
3011 - AVFormatContext.album
3012 - AVFormatContext.year
3013 - AVFormatContext.track
3014 - AVFormatContext.genre
3017 - AVProgram.provider_name
