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 - lavc 57.33.0 - avcodec.h
19 xxxxxxx - Add AVCodecParameters and its related API.
20 xxxxxxx - Add av_get_audio_frame_duration2().
22 2016-03-11 - xxxxxxx - lavf/lavc 57.28.101
23 Add requirement to bitstream filtering API that returned packets with
24 size == 0 and side_data_elems == 0 are to be skipped by the caller.
26 2016-XX-XX - xxxxxxx - lavf 57.28.100
27 Add protocol blacklisting API
29 2016-02-28 - xxxxxxx - lavc 57.27.101
30 Validate AVFrame returned by get_buffer2 to have required
31 planes not NULL and unused planes set to NULL as crashes
32 and buffer overflow are possible with certain streams if
35 2016-xx-xx - xxxxxxx - lavc 57.27.100 - avcodec.h
36 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
37 the reset of the ASS ReadOrder field on flush. This affects the content of
38 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
41 2016-xx-xx - xxxxxxx - lavc 57.26.100 - avcodec.h
42 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
43 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
44 The default value for this option will change to "ass" at the next major
45 libavcodec version bump.
47 The current default is "ass_with_timings" for compatibility. This means that
48 all subtitles text decoders currently still output ASS with timings printed
49 as strings in the AVSubtitles.rects[N]->ass fields.
51 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
52 timing is limited to a 1/100 time base, so this is relevant for any subtitles
53 format needing a bigger one), ease timing adjustments, and prevents the need
54 of removing the timing from the decoded string yourself. This form is also
55 known as "the Matroska form". The timing information (start time, duration)
56 can be found in the AVSubtitles fields.
58 2016-xx-xx - lavc 57.25.0 - avcodec.h
59 Add AVCodecContext.hw_frames_ctx.
61 2016-xx-xx - lavfi 6.36.0 - avfilter.h
62 xxxxxxx avfilter.h - Add AVFilterLink.hw_frames_ctx.
63 xxxxxxx buffersrc.h - Add AVBufferSrcParameters and functions for handling it.
65 2016-02-xx - xxxxxxx - lavc 57.25.100
66 Add AV_PKT_DATA_MPEGTS_STREAM_ID for exporting the MPEGTS stream ID.
68 2016-xx-xx - lavu 55.18.100
69 xxxxxxx audio_fifo.h - Add av_audio_fifo_peek_at().
71 2016-xx-xx - lavu 55.18.0
72 xxxxxxx buffer.h - Add av_buffer_pool_init2().
73 xxxxxxx hwcontext.h - Add a new installed header hwcontext.h with a new API
74 for handling hwaccel frames.
75 xxxxxxx hwcontext_cuda.h - Add a new installed header hwcontext_cuda.h with
76 CUDA-specific hwcontext definitions.
77 xxxxxxx hwcontext_vdpau.h - Add a new installed header hwcontext_vdpau.h with
78 VDPAU-specific hwcontext definitions.
79 xxxxxxx pixfmt.h - Add AV_PIX_FMT_CUDA.

1144 Remove avcodec_default_free_buffers(), which should not have ever
1145 been called from outside of lavc.
1146 Deprecate the following AVFrame fields:
1147 * base -- is now stored in AVBufferRef
1148 * reference, type, buffer_hints -- are unnecessary in the new API
1149 * hwaccel_picture_private, owner, thread_opaque -- should not
1150 have been acessed from outside of lavc
1151 * qscale_table, qstride, qscale_type, mbskip_table, motion_val,

1310 For audio formats with fixed frame size, the last frame
1311 no longer needs to be padded with silence, libavcodec
1312 will handle this internally (effectively all encoders
1313 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2461 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2462 Change the signature of avfilter_register() to make it return an
2463 int. This is required since now the registration operation may fail.

2490 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2491 Add a pts field to AVSubtitle which gives the subtitle packet pts
2492 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

2495 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2496 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2497 major version. Use AV_PKT_FLAG_KEY instead.
2499 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2500 av_lockmgr_register() can be used to register a callback function
2501 that lavc (and in the future, libraries that depend on lavc) can use
2502 to implement mutexes. The application should provide a callback function
2503 that implements the AV_LOCK_* operations described in avcodec.h.
2504 When the lock manager is registered, FFmpeg is guaranteed to behave
2505 correctly in a multi-threaded application.
2507 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2508 av_free_packet() is no longer an inline function. It is now exported.
2510 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2511 Please use NULL instead. This has been supported since r16506
2512 (lavf > 52.23.1, lavc > 52.10.0).
2514 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2515 The old decoding functions are deprecated, all new code should use the
2516 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2517 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2518 argument instead of a const uint8_t *buf / int buf_size pair.
2520 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2521 Introduce the av_fifo_space() function.
2523 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2524 Move AVPacket declaration from libavformat/avformat.h to
2525 libavcodec/avcodec.h.
2527 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2528 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2529 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2530 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2531 PIX_FMT_BGR32_1 are now macros.
2532 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2533 Re-sort the enum PixelFormat list accordingly.
2534 This change breaks API/ABI backward compatibility.
2536 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2537 Add the enum PixelFormat values:
2538 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2539 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2541 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2542 The Mersenne Twister PRNG implemented through the av_random* functions
2543 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2546 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2547 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2548 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2549 and av_fifo_realloc2.
2550 In addition, the order of the function arguments of av_fifo_generic_read
2551 was changed to match av_fifo_generic_write.
2552 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2553 applications, they may not use sizeof() or directly access members.
2555 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2556 Introduce a new metadata API (see av_metadata_get() and friends).
2557 The old API is now deprecated and should not be used anymore. This especially
2558 includes the following structure fields:
2559 - AVFormatContext.title
2560 - AVFormatContext.author
2561 - AVFormatContext.copyright
2562 - AVFormatContext.comment
2563 - AVFormatContext.album
2564 - AVFormatContext.year
2565 - AVFormatContext.track
2566 - AVFormatContext.genre
2569 - AVProgram.provider_name
