20 written to the target buffer.
22 2016-xx-xx - xxxxxxx - lavc 57.37.100 - avcodec.h
23 Add a new audio/video encoding and decoding API with decoupled input
24 and output -- avcodec_send_packet(), avcodec_receive_frame(),
25 avcodec_send_frame() and avcodec_receive_packet().
27 2016-xx-xx - xxxxxxx - lavc 57.15.0 - avcodec.h
28 Add a new bitstream filtering API working with AVPackets.
29 Deprecate the old bitstream filtering API.
31 2016-xx-xx - xxxxxxx - lavfi 6.42.0 - avfilter.h

37 2016-xx-xx - xxxxxxx - lavu 55.21.0 - hwcontext.h
38 Add AVHWFramesConstraints and associated API.
40 2016-04-11 - xxxxxxx - lavf 57.33.0 - avformat.h
41 Add AVStream.codecpar, deprecate AVStream.codec.
43 2016-04-02 - xxxxxxx - lavu 55.20.100 - base64.h
44 Add AV_BASE64_DECODE_SIZE(x) macro.
46 2016-xx-xx - lavc 57.33.0 - avcodec.h
47 xxxxxxx - Add AVCodecParameters and its related API.
48 xxxxxxx - Add av_get_audio_frame_duration2().
50 2016-03-11 - xxxxxxx - lavf/lavc 57.28.101
51 Add requirement to bitstream filtering API that returned packets with
52 size == 0 and side_data_elems == 0 are to be skipped by the caller.
54 2016-XX-XX - xxxxxxx - lavf 57.28.100
55 Add protocol blacklisting API
57 2016-02-28 - xxxxxxx - lavc 57.27.101
58 Validate AVFrame returned by get_buffer2 to have required
59 planes not NULL and unused planes set to NULL as crashes
60 and buffer overflow are possible with certain streams if
63 2016-xx-xx - xxxxxxx - lavc 57.27.100 - avcodec.h
64 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
65 the reset of the ASS ReadOrder field on flush. This affects the content of
66 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
69 2016-xx-xx - xxxxxxx - lavc 57.26.100 - avcodec.h
70 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
71 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
72 The default value for this option will change to "ass" at the next major
73 libavcodec version bump.
75 The current default is "ass_with_timings" for compatibility. This means that
76 all subtitles text decoders currently still output ASS with timings printed
77 as strings in the AVSubtitles.rects[N]->ass fields.
79 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
80 timing is limited to a 1/100 time base, so this is relevant for any subtitles
81 format needing a bigger one), ease timing adjustments, and prevents the need
82 of removing the timing from the decoded string yourself. This form is also
83 known as "the Matroska form". The timing information (start time, duration)
84 can be found in the AVSubtitles fields.
86 2016-xx-xx - lavc 57.25.0 - avcodec.h
87 Add AVCodecContext.hw_frames_ctx.
89 2016-xx-xx - lavfi 6.36.0 - avfilter.h

93 2016-02-xx - xxxxxxx - lavc 57.25.100
94 Add AV_PKT_DATA_MPEGTS_STREAM_ID for exporting the MPEGTS stream ID.
96 2016-xx-xx - lavu 55.18.100
97 xxxxxxx audio_fifo.h - Add av_audio_fifo_peek_at().
99 2016-xx-xx - lavu 55.18.0
100 xxxxxxx buffer.h - Add av_buffer_pool_init2().

2283 Change the field types:
2284 enum PixelFormat format -> int format in AVFilterBuffer
2285 enum PixelFormat *formats -> int *formats in AVFilterFormats
2286 enum PixelFormat *format -> int format in AVFilterLink
2288 Change the function signatures:
2289 AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
2290 AVFilterFormats *avfilter_make_format_list(const int *fmts);
2292 int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
2293 int avfilter_add_format (AVFilterFormats **avff, int fmt);
2295 AVFilterFormats *avfilter_all_colorspaces(void); ->
2296 AVFilterFormats *avfilter_all_formats (enum AVMediaType type);
2298 This change breaks libavfilter API/ABI.

2486 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2487 Introduce the avfilter_next() function.
2489 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2490 Change the signature of avfilter_register() to make it return an
2491 int. This is required since now the registration operation may fail.
2493 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2494 Make the pixdesc.h API public.

2513 Add w and h fields to AVFilterPic.
2515 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2516 This is now an unsigned int instead of a signed int.
2518 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2519 Add a pts field to AVSubtitle which gives the subtitle packet pts
2520 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2521 not work right without this.
2523 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2524 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2525 major version. Use AV_PKT_FLAG_KEY instead.
2527 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2528 av_lockmgr_register() can be used to register a callback function
2529 that lavc (and in the future, libraries that depend on lavc) can use
2530 to implement mutexes. The application should provide a callback function
2531 that implements the AV_LOCK_* operations described in avcodec.h.
2532 When the lock manager is registered, FFmpeg is guaranteed to behave
2533 correctly in a multi-threaded application.
2535 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2536 av_free_packet() is no longer an inline function. It is now exported.
2538 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2539 Please use NULL instead. This has been supported since r16506
2540 (lavf > 52.23.1, lavc > 52.10.0).
2542 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2543 The old decoding functions are deprecated, all new code should use the
2544 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2545 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2546 argument instead of a const uint8_t *buf / int buf_size pair.
2548 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2549 Introduce the av_fifo_space() function.
2551 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2552 Move AVPacket declaration from libavformat/avformat.h to
2553 libavcodec/avcodec.h.
2555 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2556 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2557 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2558 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2559 PIX_FMT_BGR32_1 are now macros.
2560 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2561 Re-sort the enum PixelFormat list accordingly.
2562 This change breaks API/ABI backward compatibility.
2564 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2565 Add the enum PixelFormat values:
2566 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2567 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2569 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2570 The Mersenne Twister PRNG implemented through the av_random* functions
2571 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2574 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2575 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2576 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2577 and av_fifo_realloc2.
2578 In addition, the order of the function arguments of av_fifo_generic_read
2579 was changed to match av_fifo_generic_write.
2580 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2581 applications, they may not use sizeof() or directly access members.
2583 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2584 Introduce a new metadata API (see av_metadata_get() and friends).
2585 The old API is now deprecated and should not be used anymore. This especially
2586 includes the following structure fields:
2587 - AVFormatContext.title
2588 - AVFormatContext.author
2589 - AVFormatContext.copyright
2590 - AVFormatContext.comment
2591 - AVFormatContext.album
2592 - AVFormatContext.year
2593 - AVFormatContext.track
2594 - AVFormatContext.genre
2597 - AVProgram.provider_name
