121 Decoders now export the frame timestamp as AVFrame.pts. It was
122 previously exported as AVFrame.pkt_pts, which is now deprecated.
124 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
125 and not the codec timebase.

166 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
167 Moved codecpar field from AVStream to the end of the struct, so that
168 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
170 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h

175 Fix accidental ABI breakage in AVFilterContext.
176 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
178 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
179 compatible with lavfi>=6.47.100. Potentially also affects other users of
180 libavfilter if they are using one of the affected fields.
182 -------- 8< --------- FFmpeg 3.1 was cut here -------- 8< ---------
184 2016-06-26 - 481f320 / 1c9e861 - lavu 55.27.100 / 55.13.0 - hwcontext.h

233 Add requirement to bitstream filtering API that returned packets with
234 size == 0 and side_data_elems == 0 are to be skipped by the caller.
236 2016-03-04 - 9362973 - lavf 57.28.100
237 Add protocol blacklisting API
239 2016-02-28 - 4dd4d53 - lavc 57.27.101
240 Validate AVFrame returned by get_buffer2 to have required
241 planes not NULL and unused planes set to NULL as crashes
242 and buffer overflow are possible with certain streams if
243 that is not the case.
245 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
246 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
247 the reset of the ASS ReadOrder field on flush. This affects the content of
248 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
251 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
252 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
253 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
254 The default value for this option will change to "ass" at the next major
255 libavcodec version bump.
257 The current default is "ass_with_timings" for compatibility. This means that
258 all subtitles text decoders currently still output ASS with timings printed
259 as strings in the AVSubtitles.rects[N]->ass fields.
261 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
262 timing is limited to a 1/100 time base, so this is relevant for any subtitles
263 format needing a bigger one), ease timing adjustments, and prevents the need
264 of removing the timing from the decoded string yourself. This form is also
265 known as "the Matroska form". The timing information (start time, duration)
266 can be found in the AVSubtitles fields.

1494 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
1495 should now be used instead of accessing AVFilterPad members

2662 2009-12-05 - a13a543 - lavfi 1.12.0 - avfilter_draw_slice()
2663 Add a slice_dir parameter to avfilter_draw_slice().
2665 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
2666 Remove the next field from AVFilter, this is not anymore required.
2668 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2669 Introduce the avfilter_next() function.
2671 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2672 Change the signature of avfilter_register() to make it return an
2673 int. This is required since now the registration operation may fail.
2675 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2676 Make the pixdesc.h API public.
2678 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
2679 Add a next field to AVFilter, this is used for simplifying the
2680 registration and management of the registered filters.
2682 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
2683 Add a description field to AVFilter.
2685 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2686 Change the interface of avfilter_make_format_list() from
2687 avfilter_make_format_list(int n, ...) to
2688 avfilter_make_format_list(enum PixelFormat *pix_fmts).
2690 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
2691 Make avfilter_get_video_buffer() recursive and add the w and h
2694 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
2695 Add w and h fields to AVFilterPic.
2697 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2698 This is now an unsigned int instead of a signed int.
2700 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2701 Add a pts field to AVSubtitle which gives the subtitle packet pts
2702 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2703 not work right without this.
2705 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2706 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2707 major version. Use AV_PKT_FLAG_KEY instead.
2709 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2710 av_lockmgr_register() can be used to register a callback function
2711 that lavc (and in the future, libraries that depend on lavc) can use
2712 to implement mutexes. The application should provide a callback function
2713 that implements the AV_LOCK_* operations described in avcodec.h.
2714 When the lock manager is registered, FFmpeg is guaranteed to behave
2715 correctly in a multi-threaded application.
2717 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2718 av_free_packet() is no longer an inline function. It is now exported.
2720 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2721 Please use NULL instead. This has been supported since r16506
2722 (lavf > 52.23.1, lavc > 52.10.0).
2724 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2725 The old decoding functions are deprecated, all new code should use the
2726 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2727 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2728 argument instead of a const uint8_t *buf / int buf_size pair.
2730 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2731 Introduce the av_fifo_space() function.
2733 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2734 Move AVPacket declaration from libavformat/avformat.h to
2735 libavcodec/avcodec.h.
2737 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2738 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2739 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2740 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2741 PIX_FMT_BGR32_1 are now macros.
2742 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2743 Re-sort the enum PixelFormat list accordingly.
2744 This change breaks API/ABI backward compatibility.
2746 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2747 Add the enum PixelFormat values:
2748 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2749 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2751 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2752 The Mersenne Twister PRNG implemented through the av_random* functions
2753 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2756 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2757 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2758 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2759 and av_fifo_realloc2.
2760 In addition, the order of the function arguments of av_fifo_generic_read
2761 was changed to match av_fifo_generic_write.
2762 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2763 applications, they may not use sizeof() or directly access members.
2765 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2766 Introduce a new metadata API (see av_metadata_get() and friends).
2767 The old API is now deprecated and should not be used anymore. This especially
2768 includes the following structure fields:
2769 - AVFormatContext.title
2770 - AVFormatContext.author
2771 - AVFormatContext.copyright
2772 - AVFormatContext.comment
2773 - AVFormatContext.album
2774 - AVFormatContext.year
2775 - AVFormatContext.track
2776 - AVFormatContext.genre
2779 - AVProgram.provider_name
