97 Decoders now export the frame timestamp as AVFrame.pts. It was
98 previously exported as AVFrame.pkt_pts, which is now deprecated.
100 Note: When decoding, AVFrame.pts uses the stream/packet timebase,

142 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
143 Moved codecpar field from AVStream to the end of the struct, so that
144 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
146 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
147 Moved hw_frames_ctx field from AVFrame to the end of the struct, so that

150 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
151 Fix accidental ABI breakage in AVFilterContext.
152 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
154 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
155 compatible with lavfi>=6.47.100. Potentially also affects other users of
156 libavfilter if they are using one of the affected fields.
158 -------- 8< --------- FFmpeg 3.1 was cut here -------- 8< ---------
160 2016-06-26 - 481f320 / 1c9e861 - lavu 55.27.100 / 55.13.0 - hwcontext.h

193 Add new installed header with VAAPI-specific hwcontext definitions.
195 2016-04-14 - afccfaf / b1f01e8 - lavu 55.21.100 / 55.7.0 - hwcontext.h
196 Add AVHWFramesConstraints and associated API.

208 2016-03-11 - 6d8ab35 - lavf/lavc 57.28.101
209 Add requirement to bitstream filtering API that returned packets with
210 size == 0 and side_data_elems == 0 are to be skipped by the caller.
212 2016-03-04 - 9362973 - lavf 57.28.100
213 Add protocol blacklisting API
215 2016-02-28 - 4dd4d53 - lavc 57.27.101
216 Validate AVFrame returned by get_buffer2 to have required
217 planes not NULL and unused planes set to NULL as crashes
218 and buffer overflow are possible with certain streams if
219 that is not the case.
221 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
222 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
223 the reset of the ASS ReadOrder field on flush. This affects the content of
224 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
227 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
228 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
229 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
230 The default value for this option will change to "ass" at the next major
231 libavcodec version bump.
233 The current default is "ass_with_timings" for compatibility. This means that
234 all subtitles text decoders currently still output ASS with timings printed
235 as strings in the AVSubtitles.rects[N]->ass fields.
237 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
238 timing is limited to a 1/100 time base, so this is relevant for any subtitles
239 format needing a bigger one), ease timing adjustments, and prevents the need
240 of removing the timing from the decoded string yourself. This form is also
241 known as "the Matroska form". The timing information (start time, duration)
242 can be found in the AVSubtitles fields.

2652 Make the pixdesc.h API public.
2654 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
2655 Add a next field to AVFilter, this is used for simplifying the
2656 registration and management of the registered filters.
2658 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
2659 Add a description field to AVFilter.
2661 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2662 Change the interface of avfilter_make_format_list() from
2663 avfilter_make_format_list(int n, ...) to
2664 avfilter_make_format_list(enum PixelFormat *pix_fmts).
2666 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
2667 Make avfilter_get_video_buffer() recursive and add the w and h
2670 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
2671 Add w and h fields to AVFilterPic.
2673 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2674 This is now an unsigned int instead of a signed int.
2676 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2677 Add a pts field to AVSubtitle which gives the subtitle packet pts
2678 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2679 not work right without this.
2681 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2682 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2683 major version. Use AV_PKT_FLAG_KEY instead.
2685 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2686 av_lockmgr_register() can be used to register a callback function
2687 that lavc (and in the future, libraries that depend on lavc) can use
2688 to implement mutexes. The application should provide a callback function
2689 that implements the AV_LOCK_* operations described in avcodec.h.
2690 When the lock manager is registered, FFmpeg is guaranteed to behave
2691 correctly in a multi-threaded application.
2693 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2694 av_free_packet() is no longer an inline function. It is now exported.
2696 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2697 Please use NULL instead. This has been supported since r16506
2698 (lavf > 52.23.1, lavc > 52.10.0).
2700 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2701 The old decoding functions are deprecated, all new code should use the
2702 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2703 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2704 argument instead of a const uint8_t *buf / int buf_size pair.
2706 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2707 Introduce the av_fifo_space() function.
2709 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2710 Move AVPacket declaration from libavformat/avformat.h to
2711 libavcodec/avcodec.h.
2713 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2714 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2715 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2716 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2717 PIX_FMT_BGR32_1 are now macros.
2718 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2719 Re-sort the enum PixelFormat list accordingly.
2720 This change breaks API/ABI backward compatibility.
2722 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2723 Add the enum PixelFormat values:
2724 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2725 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2727 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2728 The Mersenne Twister PRNG implemented through the av_random* functions
2729 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2732 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2733 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2734 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2735 and av_fifo_realloc2.
2736 In addition, the order of the function arguments of av_fifo_generic_read
2737 was changed to match av_fifo_generic_write.
2738 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2739 applications, they may not use sizeof() or directly access members.
2741 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2742 Introduce a new metadata API (see av_metadata_get() and friends).
2743 The old API is now deprecated and should not be used anymore. This especially
2744 includes the following structure fields:
2745 - AVFormatContext.title
2746 - AVFormatContext.author
2747 - AVFormatContext.copyright
2748 - AVFormatContext.comment
2749 - AVFormatContext.album
2750 - AVFormatContext.year
2751 - AVFormatContext.track
2752 - AVFormatContext.genre
2755 - AVProgram.provider_name
