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

1147 Deprecate AVCodecContext.get_buffer() / release_buffer() /
1148 reget_buffer(), avcodec_default_get_buffer(),
1149 avcodec_default_reget_buffer(), avcodec_default_release_buffer().
1150 Remove avcodec_default_free_buffers(), which should not have ever
1151 been called from outside of lavc.
1152 Deprecate the following AVFrame fields:
1153 * base -- is now stored in AVBufferRef
1154 * reference, type, buffer_hints -- are unnecessary in the new API
1155 * hwaccel_picture_private, owner, thread_opaque -- should not
1156 have been acessed from outside of lavc
1157 * qscale_table, qstride, qscale_type, mbskip_table, motion_val,
1158 mb_type, dct_coeff, ref_index -- mpegvideo-specific tables,
1159 which are not exported anymore.

1316 For audio formats with fixed frame size, the last frame
1317 no longer needs to be padded with silence, libavcodec
1318 will handle this internally (effectively all encoders
1319 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2467 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2468 Change the signature of avfilter_register() to make it return an
2469 int. This is required since now the registration operation may fail.
2471 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2472 Make the pixdesc.h API public.

2496 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2497 Add a pts field to AVSubtitle which gives the subtitle packet pts
2498 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

2501 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2502 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2503 major version. Use AV_PKT_FLAG_KEY instead.
2505 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2506 av_lockmgr_register() can be used to register a callback function
2507 that lavc (and in the future, libraries that depend on lavc) can use
2508 to implement mutexes. The application should provide a callback function
2509 that implements the AV_LOCK_* operations described in avcodec.h.
2510 When the lock manager is registered, FFmpeg is guaranteed to behave
2511 correctly in a multi-threaded application.
2513 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2514 av_free_packet() is no longer an inline function. It is now exported.
2516 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2517 Please use NULL instead. This has been supported since r16506
2518 (lavf > 52.23.1, lavc > 52.10.0).
2520 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2521 The old decoding functions are deprecated, all new code should use the
2522 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2523 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2524 argument instead of a const uint8_t *buf / int buf_size pair.
2526 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2527 Introduce the av_fifo_space() function.
2529 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2530 Move AVPacket declaration from libavformat/avformat.h to
2531 libavcodec/avcodec.h.
2533 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2534 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2535 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2536 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2537 PIX_FMT_BGR32_1 are now macros.
2538 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2539 Re-sort the enum PixelFormat list accordingly.
2540 This change breaks API/ABI backward compatibility.
2542 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2543 Add the enum PixelFormat values:
2544 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2545 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2547 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2548 The Mersenne Twister PRNG implemented through the av_random* functions
2549 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2552 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2553 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2554 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2555 and av_fifo_realloc2.
2556 In addition, the order of the function arguments of av_fifo_generic_read
2557 was changed to match av_fifo_generic_write.
2558 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2559 applications, they may not use sizeof() or directly access members.
2561 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2562 Introduce a new metadata API (see av_metadata_get() and friends).
2563 The old API is now deprecated and should not be used anymore. This especially
2564 includes the following structure fields:
2565 - AVFormatContext.title
2566 - AVFormatContext.author
2567 - AVFormatContext.copyright
2568 - AVFormatContext.comment
2569 - AVFormatContext.album
2570 - AVFormatContext.year
2571 - AVFormatContext.track
2572 - AVFormatContext.genre
2575 - AVProgram.provider_name
