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
10 libpostproc: 2015-08-28
11 libswresample: 2015-08-28
12 libswscale: 2015-08-28
16 API changes, most recent first:
18 2016-02-28 - xxxxxxx - lavc 57.27.101
19 Validate AVFrame returned by get_buffer2 to have required
20 planes not NULL and unused planes set to NULL as crashes
21 and buffer overflow are possible with certain streams if
24 2016-xx-xx - xxxxxxx - lavc 57.27.100 - avcodec.h
25 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
26 the reset of the ASS ReadOrder field on flush. This affects the content of
27 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
30 2016-xx-xx - xxxxxxx - lavc 57.26.100 - avcodec.h
31 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
32 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
33 The default value for this option will change to "ass" at the next major
34 libavcodec version bump.
36 The current default is "ass_with_timings" for compatibility. This means that
37 all subtitles text decoders currently still output ASS with timings printed
38 as strings in the AVSubtitles.rects[N]->ass fields.
40 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
41 timing is limited to a 1/100 time base, so this is relevant for any subtitles
42 format needing a bigger one), ease timing adjustments, and prevents the need
43 of removing the timing from the decoded string yourself. This form is also
44 known as "the Matroska form". The timing information (start time, duration)
45 can be found in the AVSubtitles fields.
47 2016-xx-xx - lavc 57.25.0 - avcodec.h
48 Add AVCodecContext.hw_frames_ctx.
50 2016-xx-xx - lavfi 6.36.0 - avfilter.h

54 2016-02-xx - xxxxxxx - lavc 57.25.100
55 Add AV_PKT_DATA_MPEGTS_STREAM_ID for exporting the MPEGTS stream ID.
57 2016-xx-xx - lavu 55.18.100
58 xxxxxxx audio_fifo.h - Add av_audio_fifo_peek_at().
60 2016-xx-xx - lavu 55.18.0

2450 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2451 Change the signature of avfilter_register() to make it return an
2452 int. This is required since now the registration operation may fail.
2454 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2455 Make the pixdesc.h API public.

2479 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2480 Add a pts field to AVSubtitle which gives the subtitle packet pts
2481 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

2484 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2485 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2486 major version. Use AV_PKT_FLAG_KEY instead.
2488 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2489 av_lockmgr_register() can be used to register a callback function
2490 that lavc (and in the future, libraries that depend on lavc) can use
2491 to implement mutexes. The application should provide a callback function
2492 that implements the AV_LOCK_* operations described in avcodec.h.
2493 When the lock manager is registered, FFmpeg is guaranteed to behave
2494 correctly in a multi-threaded application.
2496 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2497 av_free_packet() is no longer an inline function. It is now exported.
2499 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2500 Please use NULL instead. This has been supported since r16506
2501 (lavf > 52.23.1, lavc > 52.10.0).
2503 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2504 The old decoding functions are deprecated, all new code should use the
2505 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2506 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2507 argument instead of a const uint8_t *buf / int buf_size pair.
2509 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2510 Introduce the av_fifo_space() function.
2512 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2513 Move AVPacket declaration from libavformat/avformat.h to
2514 libavcodec/avcodec.h.
2516 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2517 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2518 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2519 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2520 PIX_FMT_BGR32_1 are now macros.
2521 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2522 Re-sort the enum PixelFormat list accordingly.
2523 This change breaks API/ABI backward compatibility.
2525 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2526 Add the enum PixelFormat values:
2527 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2528 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2530 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2531 The Mersenne Twister PRNG implemented through the av_random* functions
2532 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2535 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2536 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2537 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2538 and av_fifo_realloc2.
2539 In addition, the order of the function arguments of av_fifo_generic_read
2540 was changed to match av_fifo_generic_write.
2541 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2542 applications, they may not use sizeof() or directly access members.
2544 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2545 Introduce a new metadata API (see av_metadata_get() and friends).
2546 The old API is now deprecated and should not be used anymore. This especially
2547 includes the following structure fields:
2548 - AVFormatContext.title
2549 - AVFormatContext.author
2550 - AVFormatContext.copyright
2551 - AVFormatContext.comment
2552 - AVFormatContext.album
2553 - AVFormatContext.year
2554 - AVFormatContext.track
2555 - AVFormatContext.genre
2558 - AVProgram.provider_name
