16 API changes, most recent first:
18 2016-xx-xx - xxxxxxx - lavu 55.21.0 - hwcontext.h
19 Add AVHWFramesConstraints and associated API.
21 2016-04-11 - xxxxxxx - lavf 57.33.0 - avformat.h
22 Add AVStream.codecpar, deprecate AVStream.codec.
24 2016-04-02 - xxxxxxx - lavu 55.20.100 - base64.h
25 Add AV_BASE64_DECODE_SIZE(x) macro.
27 2016-xx-xx - lavc 57.33.0 - avcodec.h
28 xxxxxxx - Add AVCodecParameters and its related API.
29 xxxxxxx - Add av_get_audio_frame_duration2().
31 2016-03-11 - xxxxxxx - lavf/lavc 57.28.101
32 Add requirement to bitstream filtering API that returned packets with
33 size == 0 and side_data_elems == 0 are to be skipped by the caller.
35 2016-XX-XX - xxxxxxx - lavf 57.28.100
36 Add protocol blacklisting API
38 2016-02-28 - xxxxxxx - lavc 57.27.101
39 Validate AVFrame returned by get_buffer2 to have required
40 planes not NULL and unused planes set to NULL as crashes
41 and buffer overflow are possible with certain streams if
44 2016-xx-xx - xxxxxxx - lavc 57.27.100 - avcodec.h
45 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
46 the reset of the ASS ReadOrder field on flush. This affects the content of
47 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
50 2016-xx-xx - xxxxxxx - lavc 57.26.100 - avcodec.h
51 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
52 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
53 The default value for this option will change to "ass" at the next major
54 libavcodec version bump.
56 The current default is "ass_with_timings" for compatibility. This means that
57 all subtitles text decoders currently still output ASS with timings printed
58 as strings in the AVSubtitles.rects[N]->ass fields.
60 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
61 timing is limited to a 1/100 time base, so this is relevant for any subtitles
62 format needing a bigger one), ease timing adjustments, and prevents the need
63 of removing the timing from the decoded string yourself. This form is also
64 known as "the Matroska form". The timing information (start time, duration)
65 can be found in the AVSubtitles fields.
67 2016-xx-xx - lavc 57.25.0 - avcodec.h
68 Add AVCodecContext.hw_frames_ctx.
70 2016-xx-xx - lavfi 6.36.0 - avfilter.h
71 xxxxxxx avfilter.h - Add AVFilterLink.hw_frames_ctx.
72 xxxxxxx buffersrc.h - Add AVBufferSrcParameters and functions for handling it.
74 2016-02-xx - xxxxxxx - lavc 57.25.100
75 Add AV_PKT_DATA_MPEGTS_STREAM_ID for exporting the MPEGTS stream ID.
77 2016-xx-xx - lavu 55.18.100
78 xxxxxxx audio_fifo.h - Add av_audio_fifo_peek_at().
80 2016-xx-xx - lavu 55.18.0
81 xxxxxxx buffer.h - Add av_buffer_pool_init2().

1146 video decoders return reference-counted frames. Add get_buffer2()
1147 callback to AVCodecContext which allocates reference-counted frames.
1148 Add avcodec_default_get_buffer2() as the default get_buffer2()
1150 Deprecate AVCodecContext.get_buffer() / release_buffer() /
1151 reget_buffer(), avcodec_default_get_buffer(),
1152 avcodec_default_reget_buffer(), avcodec_default_release_buffer().
1153 Remove avcodec_default_free_buffers(), which should not have ever
1154 been called from outside of lavc.
1155 Deprecate the following AVFrame fields:
1156 * base -- is now stored in AVBufferRef
1157 * reference, type, buffer_hints -- are unnecessary in the new API
1158 * hwaccel_picture_private, owner, thread_opaque -- should not
1159 have been acessed from outside of lavc
1160 * qscale_table, qstride, qscale_type, mbskip_table, motion_val,
1161 mb_type, dct_coeff, ref_index -- mpegvideo-specific tables,
1162 which are not exported anymore.

1164 av_buffersrc_add_frame(), deprecate av_buffersrc_buffer().

1166 deprecate av_buffersink_read() and av_buffersink_read_samples().
1167 Deprecate AVFilterBufferRef and all functions for working with it.

1319 For audio formats with fixed frame size, the last frame
1320 no longer needs to be padded with silence, libavcodec
1321 will handle this internally (effectively all encoders
1322 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2470 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2471 Change the signature of avfilter_register() to make it return an
2472 int. This is required since now the registration operation may fail.
2474 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2475 Make the pixdesc.h API public.

2499 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2500 Add a pts field to AVSubtitle which gives the subtitle packet pts
2501 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

2504 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2505 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2506 major version. Use AV_PKT_FLAG_KEY instead.
2508 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2509 av_lockmgr_register() can be used to register a callback function
2510 that lavc (and in the future, libraries that depend on lavc) can use
2511 to implement mutexes. The application should provide a callback function
2512 that implements the AV_LOCK_* operations described in avcodec.h.
2513 When the lock manager is registered, FFmpeg is guaranteed to behave
2514 correctly in a multi-threaded application.
2516 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2517 av_free_packet() is no longer an inline function. It is now exported.
2519 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2520 Please use NULL instead. This has been supported since r16506
2521 (lavf > 52.23.1, lavc > 52.10.0).
2523 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2524 The old decoding functions are deprecated, all new code should use the
2525 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2526 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2527 argument instead of a const uint8_t *buf / int buf_size pair.
2529 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2530 Introduce the av_fifo_space() function.
2532 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2533 Move AVPacket declaration from libavformat/avformat.h to
2534 libavcodec/avcodec.h.
2536 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2537 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2538 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2539 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2540 PIX_FMT_BGR32_1 are now macros.
2541 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2542 Re-sort the enum PixelFormat list accordingly.
2543 This change breaks API/ABI backward compatibility.
2545 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2546 Add the enum PixelFormat values:
2547 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2548 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2550 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2551 The Mersenne Twister PRNG implemented through the av_random* functions
2552 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2555 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2556 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2557 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2558 and av_fifo_realloc2.
2559 In addition, the order of the function arguments of av_fifo_generic_read
2560 was changed to match av_fifo_generic_write.
2561 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2562 applications, they may not use sizeof() or directly access members.
2564 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2565 Introduce a new metadata API (see av_metadata_get() and friends).
2566 The old API is now deprecated and should not be used anymore. This especially
2567 includes the following structure fields:
2568 - AVFormatContext.title
2569 - AVFormatContext.author
2570 - AVFormatContext.copyright
2571 - AVFormatContext.comment
2572 - AVFormatContext.album
2573 - AVFormatContext.year
2574 - AVFormatContext.track
2575 - AVFormatContext.genre
2578 - AVProgram.provider_name
