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 - lavfi 7.12.100 - avfilter.h

22 Add AVCodecContext.extra_hw_frames.
24 2018-02-06 - 0fd475704e - lavd 58.1.100 - avdevice.h
25 Deprecate use of av_input_audio_device_next(), av_input_video_device_next(),
26 av_output_audio_device_next(), av_output_video_device_next().
27 Add av_indev_iterate(), and av_outdev_iterate().
29 2018-xx-xx - xxxxxxx - lavf 58.9.100 - avformat.h
30 Deprecate use of av_register_input_format(), av_register_output_format(),
31 av_register_all(), av_iformat_next(), av_oformat_next().
32 Add av_demuxer_iterate(), and av_muxer_iterate().
34 2018-xx-xx - xxxxxxx - lavc 58.10.100 - avcodec.h
35 Deprecate use of avcodec_register(), avcodec_register_all(),
36 av_codec_next(), av_register_codec_parser(), and av_parser_next().
37 Add av_codec_iterate() and av_parser_iterate().
39 2018-02-xx - xxxxxxx - lavf 58.8.100 - avformat.h
40 Deprecate the current names of the RTSP "timeout", "stimeout", "user-agent"
41 options. Introduce "listen_timeout" as replacement for the current "timeout"
42 option, and "user_agent" as replacement for "user-agent". Once the deprecation
43 is over, the old "timeout" option will be removed, and "stimeout" will be
44 renamed to "stimeout" (the "timeout" option will essentially change semantics).
46 2018-01-xx - xxxxxxx - lavf 58.7.100 - avformat.h
47 Deprecate AVFormatContext filename field which had limited length, use the
48 new dynamically allocated url field instead.
50 2018-01-xx - xxxxxxx - lavf 58.7.100 - avformat.h
51 Add url field to AVFormatContext and add ff_format_set_url helper function.
53 2018-01-xx - xxxxxxx - lavf 58.6.100 - avformat.h
54 Add AVFMTCTX_UNSEEKABLE (for HLS demuxer).

59 2018-01-xx - xxxxxxx - lavf 58.5.100 - avformat.h
60 Explicitly make avformat_network_init() and avformat_network_deinit() optional.
61 If these are not called, network initialization and deinitialization is
62 automatic, and unlike in older versions, fully supported, unless libavformat
63 is linked to ancient GnuTLS and OpenSSL.
65 2018-01-xx - xxxxxxx - lavf 58.4.100 - avformat.h
66 Deprecate AVStream.recommended_encoder_configuration. It was useful only for
67 FFserver, which has been removed.
69 2018-01-xx - xxxxxxx - lavfi 7.11.101 - avfilter.h

72 2017-xx-xx - xxxxxxx - lavr 4.0.0 - avresample.h
73 Deprecate the entire library. Merged years ago to provide compatibility
74 with Libav, it remained unmaintained by the FFmpeg project and duplicated
75 functionality provided by libswresample.
77 In order to improve consistency and reduce attack surface, it has been deprecated.
78 Users of this library are asked to migrate to libswresample, which, as well as
79 providing more functionality, is faster and has higher accuracy.
81 2017-xx-xx - xxxxxxx - lavc 58.9.100 - avcodec.h
82 Deprecate av_lockmgr_register(). You need to build FFmpeg with threading
83 support enabled to get basic thread-safety (which is the default build

121 Add AV_PIX_FMT_OPENCL.
123 2017-11-11 - 48e4eda11d - lavc 58.3.100 - avcodec.h
124 Add avcodec_get_hw_frames_parameters().

140 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
141 (avcodec_send_packet/avcodec_receive_frame) always work with reference
144 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
145 Add av_color_range_from_name(), av_color_primaries_from_name(),

296 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
297 native decoder format. (The default value is not changed.)

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

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

2949 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2950 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2951 major version. Use AV_PKT_FLAG_KEY instead.
2953 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2954 av_lockmgr_register() can be used to register a callback function
2955 that lavc (and in the future, libraries that depend on lavc) can use
2956 to implement mutexes. The application should provide a callback function
2957 that implements the AV_LOCK_* operations described in avcodec.h.
2958 When the lock manager is registered, FFmpeg is guaranteed to behave
2959 correctly in a multi-threaded application.
2961 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2962 av_free_packet() is no longer an inline function. It is now exported.
2964 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2965 Please use NULL instead. This has been supported since r16506
2966 (lavf > 52.23.1, lavc > 52.10.0).
2968 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2969 The old decoding functions are deprecated, all new code should use the
2970 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2971 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2972 argument instead of a const uint8_t *buf / int buf_size pair.
2974 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2975 Introduce the av_fifo_space() function.

2979 libavcodec/avcodec.h.
2981 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2982 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2983 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2984 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2985 PIX_FMT_BGR32_1 are now macros.
2986 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2987 Re-sort the enum PixelFormat list accordingly.
2988 This change breaks API/ABI backward compatibility.
2990 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2991 Add the enum PixelFormat values:

2993 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2995 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2996 The Mersenne Twister PRNG implemented through the av_random* functions
2997 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3000 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3001 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3002 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3003 and av_fifo_realloc2.
3004 In addition, the order of the function arguments of av_fifo_generic_read
3005 was changed to match av_fifo_generic_write.
3006 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3007 applications, they may not use sizeof() or directly access members.
3009 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3010 Introduce a new metadata API (see av_metadata_get() and friends).
3011 The old API is now deprecated and should not be used anymore. This especially
3012 includes the following structure fields:
3013 - AVFormatContext.title
3014 - AVFormatContext.author
3015 - AVFormatContext.copyright
3016 - AVFormatContext.comment
3017 - AVFormatContext.album
3018 - AVFormatContext.year
3019 - AVFormatContext.track
3020 - AVFormatContext.genre
3023 - AVProgram.provider_name
