109 Decoders now export the frame timestamp as AVFrame.pts. It was
110 previously exported as AVFrame.pkt_pts, which is now deprecated.
112 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
113 and not the codec timebase.

154 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
155 Moved codecpar field from AVStream to the end of the struct, so that
156 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
158 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
159 Moved hw_frames_ctx field from AVFrame to the end of the struct, so that

163 Fix accidental ABI breakage in AVFilterContext.
164 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
166 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
167 compatible with lavfi>=6.47.100. Potentially also affects other users of
168 libavfilter if they are using one of the affected fields.

221 Add requirement to bitstream filtering API that returned packets with
222 size == 0 and side_data_elems == 0 are to be skipped by the caller.
224 2016-03-04 - 9362973 - lavf 57.28.100

230 and buffer overflow are possible with certain streams if
231 that is not the case.
233 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
234 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
235 the reset of the ASS ReadOrder field on flush. This affects the content of
236 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
239 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
240 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
241 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
242 The default value for this option will change to "ass" at the next major
243 libavcodec version bump.
245 The current default is "ass_with_timings" for compatibility. This means that
246 all subtitles text decoders currently still output ASS with timings printed
247 as strings in the AVSubtitles.rects[N]->ass fields.
249 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
250 timing is limited to a 1/100 time base, so this is relevant for any subtitles
251 format needing a bigger one), ease timing adjustments, and prevents the need
252 of removing the timing from the decoded string yourself. This form is also
253 known as "the Matroska form". The timing information (start time, duration)
254 can be found in the AVSubtitles fields.

2657 Introduce the avfilter_next() function.
2659 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2660 Change the signature of avfilter_register() to make it return an
2661 int. This is required since now the registration operation may fail.
2663 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2664 Make the pixdesc.h API public.
2666 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
2667 Add a next field to AVFilter, this is used for simplifying the
2668 registration and management of the registered filters.
2670 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
2671 Add a description field to AVFilter.
2673 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2674 Change the interface of avfilter_make_format_list() from
2675 avfilter_make_format_list(int n, ...) to
2676 avfilter_make_format_list(enum PixelFormat *pix_fmts).
2678 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
2679 Make avfilter_get_video_buffer() recursive and add the w and h
2682 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
2683 Add w and h fields to AVFilterPic.
2685 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2686 This is now an unsigned int instead of a signed int.
2688 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2689 Add a pts field to AVSubtitle which gives the subtitle packet pts
2690 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2691 not work right without this.
2693 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2694 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2695 major version. Use AV_PKT_FLAG_KEY instead.
2697 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2698 av_lockmgr_register() can be used to register a callback function
2699 that lavc (and in the future, libraries that depend on lavc) can use
2700 to implement mutexes. The application should provide a callback function
2701 that implements the AV_LOCK_* operations described in avcodec.h.
2702 When the lock manager is registered, FFmpeg is guaranteed to behave
2703 correctly in a multi-threaded application.
2705 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2706 av_free_packet() is no longer an inline function. It is now exported.
2708 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2709 Please use NULL instead. This has been supported since r16506
2710 (lavf > 52.23.1, lavc > 52.10.0).
2712 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2713 The old decoding functions are deprecated, all new code should use the
2714 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2715 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2716 argument instead of a const uint8_t *buf / int buf_size pair.
2718 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2719 Introduce the av_fifo_space() function.
2721 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2722 Move AVPacket declaration from libavformat/avformat.h to
2723 libavcodec/avcodec.h.
2725 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2726 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2727 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2728 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2729 PIX_FMT_BGR32_1 are now macros.
2730 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2731 Re-sort the enum PixelFormat list accordingly.
2732 This change breaks API/ABI backward compatibility.
2734 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2735 Add the enum PixelFormat values:
2736 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2737 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2739 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2740 The Mersenne Twister PRNG implemented through the av_random* functions
2741 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2744 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2745 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2746 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2747 and av_fifo_realloc2.
2748 In addition, the order of the function arguments of av_fifo_generic_read
2749 was changed to match av_fifo_generic_write.
2750 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2751 applications, they may not use sizeof() or directly access members.
2753 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2754 Introduce a new metadata API (see av_metadata_get() and friends).
2755 The old API is now deprecated and should not be used anymore. This especially
2756 includes the following structure fields:
2757 - AVFormatContext.title
2758 - AVFormatContext.author
2759 - AVFormatContext.copyright
2760 - AVFormatContext.comment
2761 - AVFormatContext.album
2762 - AVFormatContext.year
2763 - AVFormatContext.track
2764 - AVFormatContext.genre
2767 - AVProgram.provider_name
