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

131 field in AVCodecParameters.
133 2016-08-15 - b746ed7 - lavc 57.52.100 - avcodec.h
134 Add a new API for chained BSF filters and passthrough (null) BSF --

143 Add FF_PROFILE_H264_MULTIVIEW_HIGH and FF_PROFILE_H264_STEREO_HIGH.
145 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
146 Moved codecpar field from AVStream to the end of the struct, so that
147 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
149 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
150 Moved hw_frames_ctx field from AVFrame to the end of the struct, so that
151 the following private fields are in the same location as in FFmpeg 3.0 (lavu 55.17.103).
153 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
154 Fix accidental ABI breakage in AVFilterContext.
155 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
157 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
158 compatible with lavfi>=6.47.100. Potentially also affects other users of
159 libavfilter if they are using one of the affected fields.
161 -------- 8< --------- FFmpeg 3.1 was cut here -------- 8< ---------
163 2016-06-26 - 481f320 / 1c9e861 - lavu 55.27.100 / 55.13.0 - hwcontext.h

196 Add new installed header with VAAPI-specific hwcontext definitions.
198 2016-04-14 - afccfaf / b1f01e8 - lavu 55.21.100 / 55.7.0 - hwcontext.h
199 Add AVHWFramesConstraints and associated API.
201 2016-04-11 - 6f69f7a / 9200514 - lavf 57.33.100 / 57.5.0 - avformat.h

209 e6053b3 / a806834 - Add av_get_audio_frame_duration2().
211 2016-03-11 - 6d8ab35 - lavf/lavc 57.28.101
212 Add requirement to bitstream filtering API that returned packets with
213 size == 0 and side_data_elems == 0 are to be skipped by the caller.
215 2016-03-04 - 9362973 - lavf 57.28.100
216 Add protocol blacklisting API
218 2016-02-28 - 4dd4d53 - lavc 57.27.101
219 Validate AVFrame returned by get_buffer2 to have required
220 planes not NULL and unused planes set to NULL as crashes
221 and buffer overflow are possible with certain streams if
222 that is not the case.
224 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
225 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
226 the reset of the ASS ReadOrder field on flush. This affects the content of
227 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
230 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
231 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
232 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
233 The default value for this option will change to "ass" at the next major
234 libavcodec version bump.
236 The current default is "ass_with_timings" for compatibility. This means that
237 all subtitles text decoders currently still output ASS with timings printed
238 as strings in the AVSubtitles.rects[N]->ass fields.
240 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
241 timing is limited to a 1/100 time base, so this is relevant for any subtitles
242 format needing a bigger one), ease timing adjustments, and prevents the need
243 of removing the timing from the decoded string yourself. This form is also
244 known as "the Matroska form". The timing information (start time, duration)
245 can be found in the AVSubtitles fields.

265 CUDA-specific hwcontext definitions.
266 d779d8d / a001ce3 hwcontext_vdpau.h - Add a new installed header hwcontext_vdpau.h with
267 VDPAU-specific hwcontext definitions.

2655 Make the pixdesc.h API public.
2657 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
2658 Add a next field to AVFilter, this is used for simplifying the
2659 registration and management of the registered filters.
2661 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
2662 Add a description field to AVFilter.
2664 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2665 Change the interface of avfilter_make_format_list() from
2666 avfilter_make_format_list(int n, ...) to
2667 avfilter_make_format_list(enum PixelFormat *pix_fmts).
2669 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
2670 Make avfilter_get_video_buffer() recursive and add the w and h
2673 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
2674 Add w and h fields to AVFilterPic.
2676 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2677 This is now an unsigned int instead of a signed int.
2679 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2680 Add a pts field to AVSubtitle which gives the subtitle packet pts
2681 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2682 not work right without this.
2684 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2685 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2686 major version. Use AV_PKT_FLAG_KEY instead.
2688 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2689 av_lockmgr_register() can be used to register a callback function
2690 that lavc (and in the future, libraries that depend on lavc) can use
2691 to implement mutexes. The application should provide a callback function
2692 that implements the AV_LOCK_* operations described in avcodec.h.
2693 When the lock manager is registered, FFmpeg is guaranteed to behave
2694 correctly in a multi-threaded application.
2696 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2697 av_free_packet() is no longer an inline function. It is now exported.
2699 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2700 Please use NULL instead. This has been supported since r16506
2701 (lavf > 52.23.1, lavc > 52.10.0).
2703 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2704 The old decoding functions are deprecated, all new code should use the
2705 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2706 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2707 argument instead of a const uint8_t *buf / int buf_size pair.
2709 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2710 Introduce the av_fifo_space() function.
2712 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2713 Move AVPacket declaration from libavformat/avformat.h to
2714 libavcodec/avcodec.h.
2716 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2717 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2718 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2719 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2720 PIX_FMT_BGR32_1 are now macros.
2721 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2722 Re-sort the enum PixelFormat list accordingly.
2723 This change breaks API/ABI backward compatibility.
2725 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2726 Add the enum PixelFormat values:
2727 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2728 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2730 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2731 The Mersenne Twister PRNG implemented through the av_random* functions
2732 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2735 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2736 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2737 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2738 and av_fifo_realloc2.
2739 In addition, the order of the function arguments of av_fifo_generic_read
2740 was changed to match av_fifo_generic_write.
2741 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2742 applications, they may not use sizeof() or directly access members.
2744 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2745 Introduce a new metadata API (see av_metadata_get() and friends).
2746 The old API is now deprecated and should not be used anymore. This especially
2747 includes the following structure fields:
2748 - AVFormatContext.title
2749 - AVFormatContext.author
2750 - AVFormatContext.copyright
2751 - AVFormatContext.comment
2752 - AVFormatContext.album
2753 - AVFormatContext.year
2754 - AVFormatContext.track
2755 - AVFormatContext.genre
2758 - AVProgram.provider_name
