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-XX-XX - xxxxxxx - lavf 57.28.100
19 Add protocol blacklisting API
21 2016-02-28 - xxxxxxx - lavc 57.27.101
22 Validate AVFrame returned by get_buffer2 to have required
23 planes not NULL and unused planes set to NULL as crashes
24 and buffer overflow are possible with certain streams if
27 2016-xx-xx - xxxxxxx - lavc 57.27.100 - avcodec.h
28 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
29 the reset of the ASS ReadOrder field on flush. This affects the content of
30 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
33 2016-xx-xx - xxxxxxx - lavc 57.26.100 - avcodec.h
34 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
35 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
36 The default value for this option will change to "ass" at the next major
37 libavcodec version bump.
39 The current default is "ass_with_timings" for compatibility. This means that
40 all subtitles text decoders currently still output ASS with timings printed
41 as strings in the AVSubtitles.rects[N]->ass fields.
43 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
44 timing is limited to a 1/100 time base, so this is relevant for any subtitles
45 format needing a bigger one), ease timing adjustments, and prevents the need
46 of removing the timing from the decoded string yourself. This form is also
47 known as "the Matroska form". The timing information (start time, duration)
48 can be found in the AVSubtitles fields.
50 2016-xx-xx - lavc 57.25.0 - avcodec.h
51 Add AVCodecContext.hw_frames_ctx.

58 Add AV_PKT_DATA_MPEGTS_STREAM_ID for exporting the MPEGTS stream ID.
60 2016-xx-xx - lavu 55.18.100

1302 For audio formats with fixed frame size, the last frame
1303 no longer needs to be padded with silence, libavcodec
1304 will handle this internally (effectively all encoders

2453 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2454 Change the signature of avfilter_register() to make it return an
2455 int. This is required since now the registration operation may fail.
2457 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2458 Make the pixdesc.h API public.

2482 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2483 Add a pts field to AVSubtitle which gives the subtitle packet pts
2484 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

2487 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2488 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2489 major version. Use AV_PKT_FLAG_KEY instead.
2491 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2492 av_lockmgr_register() can be used to register a callback function
2493 that lavc (and in the future, libraries that depend on lavc) can use
2494 to implement mutexes. The application should provide a callback function
2495 that implements the AV_LOCK_* operations described in avcodec.h.
2496 When the lock manager is registered, FFmpeg is guaranteed to behave
2497 correctly in a multi-threaded application.
2499 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2500 av_free_packet() is no longer an inline function. It is now exported.
2502 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2503 Please use NULL instead. This has been supported since r16506
2504 (lavf > 52.23.1, lavc > 52.10.0).
2506 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2507 The old decoding functions are deprecated, all new code should use the
2508 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2509 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2510 argument instead of a const uint8_t *buf / int buf_size pair.
2512 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2513 Introduce the av_fifo_space() function.
2515 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2516 Move AVPacket declaration from libavformat/avformat.h to
2517 libavcodec/avcodec.h.
2519 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2520 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2521 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2522 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2523 PIX_FMT_BGR32_1 are now macros.
2524 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2525 Re-sort the enum PixelFormat list accordingly.
2526 This change breaks API/ABI backward compatibility.
2528 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2529 Add the enum PixelFormat values:
2530 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2531 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2533 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2534 The Mersenne Twister PRNG implemented through the av_random* functions
2535 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2538 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2539 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2540 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2541 and av_fifo_realloc2.
2542 In addition, the order of the function arguments of av_fifo_generic_read
2543 was changed to match av_fifo_generic_write.
2544 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2545 applications, they may not use sizeof() or directly access members.
2547 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2548 Introduce a new metadata API (see av_metadata_get() and friends).
2549 The old API is now deprecated and should not be used anymore. This especially
2550 includes the following structure fields:
2551 - AVFormatContext.title
2552 - AVFormatContext.author
2553 - AVFormatContext.copyright
2554 - AVFormatContext.comment
2555 - AVFormatContext.album
2556 - AVFormatContext.year
2557 - AVFormatContext.track
2558 - AVFormatContext.genre
2561 - AVProgram.provider_name
