7 libavfilter: 2017-10-21
8 libavformat: 2017-10-21
9 libavresample: 2017-10-21

12 libswscale: 2017-10-21
16 API changes, most recent first:
18 2018-03-xx - xxxxxxx - lavu 56.8.100 - frame.h
19 Add av_frame_new_side_data_from_buf().
22 Change av_ripemd_update(), av_murmur3_update() and av_hash_update() length

32 Deprecate use of av_input_audio_device_next(), av_input_video_device_next(),
33 av_output_audio_device_next(), av_output_video_device_next().
34 Add av_indev_iterate(), and av_outdev_iterate().
36 2018-xx-xx - xxxxxxx - lavf 58.9.100 - avformat.h
37 Deprecate use of av_register_input_format(), av_register_output_format(),
38 av_register_all(), av_iformat_next(), av_oformat_next().
39 Add av_demuxer_iterate(), and av_muxer_iterate().
41 2018-xx-xx - xxxxxxx - lavc 58.10.100 - avcodec.h
42 Deprecate use of avcodec_register(), avcodec_register_all(),
43 av_codec_next(), av_register_codec_parser(), and av_parser_next().
44 Add av_codec_iterate() and av_parser_iterate().

47 Deprecate the current names of the RTSP "timeout", "stimeout", "user-agent"
48 options. Introduce "listen_timeout" as replacement for the current "timeout"
49 option, and "user_agent" as replacement for "user-agent". Once the deprecation
50 is over, the old "timeout" option will be removed, and "stimeout" will be
51 renamed to "stimeout" (the "timeout" option will essentially change semantics).
53 2018-01-xx - xxxxxxx - lavf 58.7.100 - avformat.h

68 If these are not called, network initialization and deinitialization is
69 automatic, and unlike in older versions, fully supported, unless libavformat
70 is linked to ancient GnuTLS and OpenSSL.
72 2018-01-xx - xxxxxxx - lavf 58.4.100 - avformat.h

79 2017-xx-xx - xxxxxxx - lavr 4.0.0 - avresample.h
80 Deprecate the entire library. Merged years ago to provide compatibility
81 with Libav, it remained unmaintained by the FFmpeg project and duplicated
82 functionality provided by libswresample.
84 In order to improve consistency and reduce attack surface, it has been deprecated.
85 Users of this library are asked to migrate to libswresample, which, as well as
86 providing more functionality, is faster and has higher accuracy.
88 2017-xx-xx - xxxxxxx - lavc 58.9.100 - avcodec.h
89 Deprecate av_lockmgr_register(). You need to build FFmpeg with threading
90 support enabled to get basic thread-safety (which is the default build

147 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
148 (avcodec_send_packet/avcodec_receive_frame) always work with reference
151 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
152 Add av_color_range_from_name(), av_color_primaries_from_name(),

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

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

2956 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2957 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2958 major version. Use AV_PKT_FLAG_KEY instead.
2960 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2961 av_lockmgr_register() can be used to register a callback function
2962 that lavc (and in the future, libraries that depend on lavc) can use
2963 to implement mutexes. The application should provide a callback function
2964 that implements the AV_LOCK_* operations described in avcodec.h.
2965 When the lock manager is registered, FFmpeg is guaranteed to behave
2966 correctly in a multi-threaded application.
2968 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2969 av_free_packet() is no longer an inline function. It is now exported.
2971 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2972 Please use NULL instead. This has been supported since r16506
2973 (lavf > 52.23.1, lavc > 52.10.0).
2975 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2976 The old decoding functions are deprecated, all new code should use the
2977 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2978 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2979 argument instead of a const uint8_t *buf / int buf_size pair.
2981 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2982 Introduce the av_fifo_space() function.

2986 libavcodec/avcodec.h.
2988 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2989 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2990 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2991 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2992 PIX_FMT_BGR32_1 are now macros.
2993 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2994 Re-sort the enum PixelFormat list accordingly.
2995 This change breaks API/ABI backward compatibility.
2997 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2998 Add the enum PixelFormat values:

3000 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3002 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3003 The Mersenne Twister PRNG implemented through the av_random* functions
3004 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3007 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3008 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3009 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3010 and av_fifo_realloc2.
3011 In addition, the order of the function arguments of av_fifo_generic_read
3012 was changed to match av_fifo_generic_write.
3013 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3014 applications, they may not use sizeof() or directly access members.
3016 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3017 Introduce a new metadata API (see av_metadata_get() and friends).
3018 The old API is now deprecated and should not be used anymore. This especially
3019 includes the following structure fields:
3020 - AVFormatContext.title
3021 - AVFormatContext.author
3022 - AVFormatContext.copyright
3023 - AVFormatContext.comment
3024 - AVFormatContext.album
3025 - AVFormatContext.year
3026 - AVFormatContext.track
3027 - AVFormatContext.genre
