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

135 field in AVCodecParameters.
137 2016-08-15 - b746ed7 - lavc 57.52.100 - avcodec.h
138 Add a new API for chained BSF filters and passthrough (null) BSF --

149 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
150 Moved codecpar field from AVStream to the end of the struct, so that
151 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
153 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h

157 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
158 Fix accidental ABI breakage in AVFilterContext.
159 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
161 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
162 compatible with lavfi>=6.47.100. Potentially also affects other users of
163 libavfilter if they are using one of the affected fields.
165 -------- 8< --------- FFmpeg 3.1 was cut here -------- 8< ---------
167 2016-06-26 - 481f320 / 1c9e861 - lavu 55.27.100 / 55.13.0 - hwcontext.h

200 Add new installed header with VAAPI-specific hwcontext definitions.
202 2016-04-14 - afccfaf / b1f01e8 - lavu 55.21.100 / 55.7.0 - hwcontext.h
203 Add AVHWFramesConstraints and associated API.
205 2016-04-11 - 6f69f7a / 9200514 - lavf 57.33.100 / 57.5.0 - avformat.h

213 e6053b3 / a806834 - Add av_get_audio_frame_duration2().
215 2016-03-11 - 6d8ab35 - lavf/lavc 57.28.101
216 Add requirement to bitstream filtering API that returned packets with
217 size == 0 and side_data_elems == 0 are to be skipped by the caller.
219 2016-03-04 - 9362973 - lavf 57.28.100
220 Add protocol blacklisting API
222 2016-02-28 - 4dd4d53 - lavc 57.27.101
223 Validate AVFrame returned by get_buffer2 to have required
224 planes not NULL and unused planes set to NULL as crashes
225 and buffer overflow are possible with certain streams if
226 that is not the case.
228 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
229 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
230 the reset of the ASS ReadOrder field on flush. This affects the content of
231 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
234 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
235 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
236 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
237 The default value for this option will change to "ass" at the next major
238 libavcodec version bump.
240 The current default is "ass_with_timings" for compatibility. This means that
241 all subtitles text decoders currently still output ASS with timings printed
242 as strings in the AVSubtitles.rects[N]->ass fields.
244 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
245 timing is limited to a 1/100 time base, so this is relevant for any subtitles
246 format needing a bigger one), ease timing adjustments, and prevents the need
247 of removing the timing from the decoded string yourself. This form is also
248 known as "the Matroska form". The timing information (start time, duration)
249 can be found in the AVSubtitles fields.

381 2015-08-19 - 9f8e57ef - lavu 54.31.100 - pixfmt.h
382 Add a unique pixel format for VA-API (AV_PIX_FMT_VAAPI) that

2656 int. This is required since now the registration operation may fail.
2658 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2659 Make the pixdesc.h API public.
2661 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
2662 Add a next field to AVFilter, this is used for simplifying the
2663 registration and management of the registered filters.
2665 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
2666 Add a description field to AVFilter.
2668 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2669 Change the interface of avfilter_make_format_list() from
2670 avfilter_make_format_list(int n, ...) to
2671 avfilter_make_format_list(enum PixelFormat *pix_fmts).
2673 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
2674 Make avfilter_get_video_buffer() recursive and add the w and h
2677 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
2678 Add w and h fields to AVFilterPic.
2680 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2681 This is now an unsigned int instead of a signed int.
2683 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2684 Add a pts field to AVSubtitle which gives the subtitle packet pts
2685 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2686 not work right without this.
2688 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2689 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2690 major version. Use AV_PKT_FLAG_KEY instead.
2692 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2693 av_lockmgr_register() can be used to register a callback function
2694 that lavc (and in the future, libraries that depend on lavc) can use
2695 to implement mutexes. The application should provide a callback function
2696 that implements the AV_LOCK_* operations described in avcodec.h.
2697 When the lock manager is registered, FFmpeg is guaranteed to behave
2698 correctly in a multi-threaded application.
2700 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2701 av_free_packet() is no longer an inline function. It is now exported.
2703 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2704 Please use NULL instead. This has been supported since r16506
2705 (lavf > 52.23.1, lavc > 52.10.0).
2707 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2708 The old decoding functions are deprecated, all new code should use the
2709 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2710 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2711 argument instead of a const uint8_t *buf / int buf_size pair.
2713 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2714 Introduce the av_fifo_space() function.
2716 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2717 Move AVPacket declaration from libavformat/avformat.h to
2718 libavcodec/avcodec.h.
2720 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2721 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2722 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2723 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2724 PIX_FMT_BGR32_1 are now macros.
2725 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2726 Re-sort the enum PixelFormat list accordingly.
2727 This change breaks API/ABI backward compatibility.
2729 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2730 Add the enum PixelFormat values:
2731 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2732 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2734 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2735 The Mersenne Twister PRNG implemented through the av_random* functions
2736 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2739 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2740 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2741 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2742 and av_fifo_realloc2.
2743 In addition, the order of the function arguments of av_fifo_generic_read
2744 was changed to match av_fifo_generic_write.
2745 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2746 applications, they may not use sizeof() or directly access members.
2748 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2749 Introduce a new metadata API (see av_metadata_get() and friends).
2750 The old API is now deprecated and should not be used anymore. This especially
2751 includes the following structure fields:
2752 - AVFormatContext.title
2753 - AVFormatContext.author
2754 - AVFormatContext.copyright
2755 - AVFormatContext.comment
2756 - AVFormatContext.album
2757 - AVFormatContext.year
2758 - AVFormatContext.track
2759 - AVFormatContext.genre
2762 - AVProgram.provider_name
