93 Decoders now export the frame timestamp as AVFrame.pts. It was
94 previously exported as AVFrame.pkt_pts, which is now deprecated.
96 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
97 and not the codec timebase.

138 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
139 Moved codecpar field from AVStream to the end of the struct, so that
140 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
142 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
143 Moved hw_frames_ctx field from AVFrame to the end of the struct, so that

146 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
147 Fix accidental ABI breakage in AVFilterContext.
148 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
150 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
151 compatible with lavfi>=6.47.100. Potentially also affects other users of
152 libavfilter if they are using one of the affected fields.
154 -------- 8< --------- FFmpeg 3.1 was cut here -------- 8< ---------
156 2016-06-26 - 481f320 / 1c9e861 - lavu 55.27.100 / 55.13.0 - hwcontext.h

189 Add new installed header with VAAPI-specific hwcontext definitions.
191 2016-04-14 - afccfaf / b1f01e8 - lavu 55.21.100 / 55.7.0 - hwcontext.h
192 Add AVHWFramesConstraints and associated API.
194 2016-04-11 - 6f69f7a / 9200514 - lavf 57.33.100 / 57.5.0 - avformat.h

204 2016-03-11 - 6d8ab35 - lavf/lavc 57.28.101
205 Add requirement to bitstream filtering API that returned packets with
206 size == 0 and side_data_elems == 0 are to be skipped by the caller.
208 2016-03-04 - 9362973 - lavf 57.28.100
209 Add protocol blacklisting API
211 2016-02-28 - 4dd4d53 - lavc 57.27.101
212 Validate AVFrame returned by get_buffer2 to have required
213 planes not NULL and unused planes set to NULL as crashes
214 and buffer overflow are possible with certain streams if
215 that is not the case.
217 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
218 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
219 the reset of the ASS ReadOrder field on flush. This affects the content of
220 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
223 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
224 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
225 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
226 The default value for this option will change to "ass" at the next major
227 libavcodec version bump.
229 The current default is "ass_with_timings" for compatibility. This means that
230 all subtitles text decoders currently still output ASS with timings printed
231 as strings in the AVSubtitles.rects[N]->ass fields.
233 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
234 timing is limited to a 1/100 time base, so this is relevant for any subtitles
235 format needing a bigger one), ease timing adjustments, and prevents the need
236 of removing the timing from the decoded string yourself. This form is also
237 known as "the Matroska form". The timing information (start time, duration)
238 can be found in the AVSubtitles fields.

2659 avfilter_make_format_list(int n, ...) to
2660 avfilter_make_format_list(enum PixelFormat *pix_fmts).
2662 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
2663 Make avfilter_get_video_buffer() recursive and add the w and h
2666 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
2667 Add w and h fields to AVFilterPic.
2669 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2670 This is now an unsigned int instead of a signed int.
2672 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2673 Add a pts field to AVSubtitle which gives the subtitle packet pts
2674 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2675 not work right without this.
2677 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2678 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2679 major version. Use AV_PKT_FLAG_KEY instead.
2681 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2682 av_lockmgr_register() can be used to register a callback function
2683 that lavc (and in the future, libraries that depend on lavc) can use
2684 to implement mutexes. The application should provide a callback function
2685 that implements the AV_LOCK_* operations described in avcodec.h.
2686 When the lock manager is registered, FFmpeg is guaranteed to behave
2687 correctly in a multi-threaded application.
2689 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2690 av_free_packet() is no longer an inline function. It is now exported.
2692 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2693 Please use NULL instead. This has been supported since r16506
2694 (lavf > 52.23.1, lavc > 52.10.0).
2696 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2697 The old decoding functions are deprecated, all new code should use the
2698 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2699 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2700 argument instead of a const uint8_t *buf / int buf_size pair.
2702 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2703 Introduce the av_fifo_space() function.
2705 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2706 Move AVPacket declaration from libavformat/avformat.h to
2707 libavcodec/avcodec.h.
2709 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2710 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2711 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2712 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2713 PIX_FMT_BGR32_1 are now macros.
2714 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2715 Re-sort the enum PixelFormat list accordingly.
2716 This change breaks API/ABI backward compatibility.
2718 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2719 Add the enum PixelFormat values:
2720 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2721 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2723 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2724 The Mersenne Twister PRNG implemented through the av_random* functions
2725 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2728 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2729 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2730 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2731 and av_fifo_realloc2.
2732 In addition, the order of the function arguments of av_fifo_generic_read
2733 was changed to match av_fifo_generic_write.
2734 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2735 applications, they may not use sizeof() or directly access members.
2737 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2738 Introduce a new metadata API (see av_metadata_get() and friends).
2739 The old API is now deprecated and should not be used anymore. This especially
2740 includes the following structure fields:
2741 - AVFormatContext.title
2742 - AVFormatContext.author
2743 - AVFormatContext.copyright
2744 - AVFormatContext.comment
2745 - AVFormatContext.album
2746 - AVFormatContext.year
2747 - AVFormatContext.track
2748 - AVFormatContext.genre
2751 - AVProgram.provider_name
