18 2016-08-15 - c3c4c72 - lavc 57.53.100 - avcodec.h
19 Add trailing_padding to AVCodecContext to match the corresponding
20 field in AVCodecParameters.
22 2016-08-15 - b746ed7 - lavc 57.52.100 - avcodec.h
23 Add a new API for chained BSF filters and passthrough (null) BSF --

34 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
35 Moved codecpar field from AVStream to the end of the struct, so that
36 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
38 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
39 Moved hw_frames_ctx field from AVFrame to the end of the struct, so that

42 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
43 Fix accidental ABI breakage in AVFilterContext.
44 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
46 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
47 compatible with lavfi>=6.47.100. Potentially also affects other users of
48 libavfilter if they are using one of the affected fields.

101 Add requirement to bitstream filtering API that returned packets with
102 size == 0 and side_data_elems == 0 are to be skipped by the caller.
104 2016-03-04 - 9362973 - lavf 57.28.100

111 that is not the case.
113 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
114 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
115 the reset of the ASS ReadOrder field on flush. This affects the content of
116 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
119 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
120 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
121 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
122 The default value for this option will change to "ass" at the next major
123 libavcodec version bump.
125 The current default is "ass_with_timings" for compatibility. This means that
126 all subtitles text decoders currently still output ASS with timings printed
127 as strings in the AVSubtitles.rects[N]->ass fields.
129 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
130 timing is limited to a 1/100 time base, so this is relevant for any subtitles
131 format needing a bigger one), ease timing adjustments, and prevents the need
132 of removing the timing from the decoded string yourself. This form is also
133 known as "the Matroska form". The timing information (start time, duration)
134 can be found in the AVSubtitles fields.

2536 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2537 Introduce the avfilter_next() function.
2539 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2540 Change the signature of avfilter_register() to make it return an
2541 int. This is required since now the registration operation may fail.
2543 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2544 Make the pixdesc.h API public.

2568 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2569 Add a pts field to AVSubtitle which gives the subtitle packet pts
2570 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2571 not work right without this.
2573 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2574 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2575 major version. Use AV_PKT_FLAG_KEY instead.
2577 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2578 av_lockmgr_register() can be used to register a callback function
2579 that lavc (and in the future, libraries that depend on lavc) can use
2580 to implement mutexes. The application should provide a callback function
2581 that implements the AV_LOCK_* operations described in avcodec.h.
2582 When the lock manager is registered, FFmpeg is guaranteed to behave
2583 correctly in a multi-threaded application.
2585 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2586 av_free_packet() is no longer an inline function. It is now exported.
2588 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2589 Please use NULL instead. This has been supported since r16506
2590 (lavf > 52.23.1, lavc > 52.10.0).
2592 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2593 The old decoding functions are deprecated, all new code should use the
2594 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2595 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2596 argument instead of a const uint8_t *buf / int buf_size pair.
2598 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2599 Introduce the av_fifo_space() function.
2601 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2602 Move AVPacket declaration from libavformat/avformat.h to
2603 libavcodec/avcodec.h.
2605 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2606 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2607 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2608 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2609 PIX_FMT_BGR32_1 are now macros.
2610 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2611 Re-sort the enum PixelFormat list accordingly.
2612 This change breaks API/ABI backward compatibility.
2614 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2615 Add the enum PixelFormat values:
2616 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2617 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2619 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2620 The Mersenne Twister PRNG implemented through the av_random* functions
2621 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2624 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2625 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2626 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2627 and av_fifo_realloc2.
2628 In addition, the order of the function arguments of av_fifo_generic_read
2629 was changed to match av_fifo_generic_write.
2630 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2631 applications, they may not use sizeof() or directly access members.
2633 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2634 Introduce a new metadata API (see av_metadata_get() and friends).
2635 The old API is now deprecated and should not be used anymore. This especially
2636 includes the following structure fields:
2637 - AVFormatContext.title
2638 - AVFormatContext.author
2639 - AVFormatContext.copyright
2640 - AVFormatContext.comment
2641 - AVFormatContext.album
2642 - AVFormatContext.year
2643 - AVFormatContext.track
2644 - AVFormatContext.genre
2647 - AVProgram.provider_name
