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 2016-06-29 - xxxxxxx - lavfi 6.47.100 - avfilter.h
19 Fix accidental ABI breakage in AVFilterContext.
20 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
22 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
23 compatible with lavfi>=6.47.100. Potentially also affects other users of
24 libavfilter if they are using one of the affected fields.

89 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
90 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
91 the reset of the ASS ReadOrder field on flush. This affects the content of
92 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
95 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
96 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
97 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
98 The default value for this option will change to "ass" at the next major
99 libavcodec version bump.
101 The current default is "ass_with_timings" for compatibility. This means that
102 all subtitles text decoders currently still output ASS with timings printed
103 as strings in the AVSubtitles.rects[N]->ass fields.
105 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
106 timing is limited to a 1/100 time base, so this is relevant for any subtitles
107 format needing a bigger one), ease timing adjustments, and prevents the need
108 of removing the timing from the decoded string yourself. This form is also
109 known as "the Matroska form". The timing information (start time, duration)
110 can be found in the AVSubtitles fields.

2515 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2516 Change the signature of avfilter_register() to make it return an
2517 int. This is required since now the registration operation may fail.
2519 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2520 Make the pixdesc.h API public.
2522 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2539 Add w and h fields to AVFilterPic.
2541 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2542 This is now an unsigned int instead of a signed int.
2544 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2545 Add a pts field to AVSubtitle which gives the subtitle packet pts
2546 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2547 not work right without this.
2549 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2550 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2551 major version. Use AV_PKT_FLAG_KEY instead.
2553 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2554 av_lockmgr_register() can be used to register a callback function
2555 that lavc (and in the future, libraries that depend on lavc) can use
2556 to implement mutexes. The application should provide a callback function
2557 that implements the AV_LOCK_* operations described in avcodec.h.
2558 When the lock manager is registered, FFmpeg is guaranteed to behave
2559 correctly in a multi-threaded application.
2561 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2562 av_free_packet() is no longer an inline function. It is now exported.
2564 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2565 Please use NULL instead. This has been supported since r16506
2566 (lavf > 52.23.1, lavc > 52.10.0).
2568 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2569 The old decoding functions are deprecated, all new code should use the
2570 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2571 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2572 argument instead of a const uint8_t *buf / int buf_size pair.
2574 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2575 Introduce the av_fifo_space() function.
2577 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2578 Move AVPacket declaration from libavformat/avformat.h to
2579 libavcodec/avcodec.h.
2581 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2582 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2583 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2584 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2585 PIX_FMT_BGR32_1 are now macros.
2586 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2587 Re-sort the enum PixelFormat list accordingly.
2588 This change breaks API/ABI backward compatibility.
2590 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2591 Add the enum PixelFormat values:
2592 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2593 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2595 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2596 The Mersenne Twister PRNG implemented through the av_random* functions
2597 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2600 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2601 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2602 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2603 and av_fifo_realloc2.
2604 In addition, the order of the function arguments of av_fifo_generic_read
2605 was changed to match av_fifo_generic_write.
2606 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2607 applications, they may not use sizeof() or directly access members.
2609 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2610 Introduce a new metadata API (see av_metadata_get() and friends).
2611 The old API is now deprecated and should not be used anymore. This especially
2612 includes the following structure fields:
2613 - AVFormatContext.title
2614 - AVFormatContext.author
2615 - AVFormatContext.copyright
2616 - AVFormatContext.comment
2617 - AVFormatContext.album
2618 - AVFormatContext.year
2619 - AVFormatContext.track
2620 - AVFormatContext.genre
2623 - AVProgram.provider_name
