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: 2015-08-28
7 libavfilter: 2015-08-28
8 libavformat: 2015-08-28
9 libavresample: 2015-08-28

16 API changes, most recent first:
18 2016-07-09 - xxxxxxx / 90f469a - lavc 57.50.100 / 57.20.0 - avcodec.h
19 Add FF_PROFILE_H264_MULTIVIEW_HIGH and FF_PROFILE_H264_STEREO_HIGH.
21 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
22 Moved codecpar field from AVStream to the end of the struct, so that
23 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
25 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
26 Moved hw_frames_ctx field from AVFrame to the end of the struct, so that

29 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
30 Fix accidental ABI breakage in AVFilterContext.
31 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
33 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
34 compatible with lavfi>=6.47.100. Potentially also affects other users of
35 libavfilter if they are using one of the affected fields.
37 -------- 8< --------- FFmpeg 3.1 was cut here -------- 8< ---------

88 Add requirement to bitstream filtering API that returned packets with
89 size == 0 and side_data_elems == 0 are to be skipped by the caller.
91 2016-03-04 - 9362973 - lavf 57.28.100
92 Add protocol blacklisting API
94 2016-02-28 - 4dd4d53 - lavc 57.27.101

96 planes not NULL and unused planes set to NULL as crashes
97 and buffer overflow are possible with certain streams if
100 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
101 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
102 the reset of the ASS ReadOrder field on flush. This affects the content of
103 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
106 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
107 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
108 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
109 The default value for this option will change to "ass" at the next major
110 libavcodec version bump.
112 The current default is "ass_with_timings" for compatibility. This means that
113 all subtitles text decoders currently still output ASS with timings printed
114 as strings in the AVSubtitles.rects[N]->ass fields.
116 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
117 timing is limited to a 1/100 time base, so this is relevant for any subtitles
118 format needing a bigger one), ease timing adjustments, and prevents the need
119 of removing the timing from the decoded string yourself. This form is also
120 known as "the Matroska form". The timing information (start time, duration)
121 can be found in the AVSubtitles fields.

2523 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2524 Introduce the avfilter_next() function.
2526 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2527 Change the signature of avfilter_register() to make it return an
2528 int. This is required since now the registration operation may fail.
2530 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2531 Make the pixdesc.h API public.

2555 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2556 Add a pts field to AVSubtitle which gives the subtitle packet pts
2557 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2558 not work right without this.
2560 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2561 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2562 major version. Use AV_PKT_FLAG_KEY instead.
2564 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2565 av_lockmgr_register() can be used to register a callback function
2566 that lavc (and in the future, libraries that depend on lavc) can use
2567 to implement mutexes. The application should provide a callback function
2568 that implements the AV_LOCK_* operations described in avcodec.h.
2569 When the lock manager is registered, FFmpeg is guaranteed to behave
2570 correctly in a multi-threaded application.
2572 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2573 av_free_packet() is no longer an inline function. It is now exported.
2575 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2576 Please use NULL instead. This has been supported since r16506
2577 (lavf > 52.23.1, lavc > 52.10.0).
2579 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2580 The old decoding functions are deprecated, all new code should use the
2581 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2582 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2583 argument instead of a const uint8_t *buf / int buf_size pair.
2585 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2586 Introduce the av_fifo_space() function.
2588 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2589 Move AVPacket declaration from libavformat/avformat.h to
2590 libavcodec/avcodec.h.
2592 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2593 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2594 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2595 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2596 PIX_FMT_BGR32_1 are now macros.
2597 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2598 Re-sort the enum PixelFormat list accordingly.
2599 This change breaks API/ABI backward compatibility.
2601 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2602 Add the enum PixelFormat values:
2603 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2604 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2606 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2607 The Mersenne Twister PRNG implemented through the av_random* functions
2608 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2611 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2612 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2613 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2614 and av_fifo_realloc2.
2615 In addition, the order of the function arguments of av_fifo_generic_read
2616 was changed to match av_fifo_generic_write.
2617 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2618 applications, they may not use sizeof() or directly access members.
2620 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2621 Introduce a new metadata API (see av_metadata_get() and friends).
2622 The old API is now deprecated and should not be used anymore. This especially
2623 includes the following structure fields:
2624 - AVFormatContext.title
2625 - AVFormatContext.author
2626 - AVFormatContext.copyright
2627 - AVFormatContext.comment
2628 - AVFormatContext.album
2629 - AVFormatContext.year
2630 - AVFormatContext.track
2631 - AVFormatContext.genre
2634 - AVProgram.provider_name
