80 previously exported as AVFrame.pkt_pts, which is now deprecated.
82 Note: When decoding, AVFrame.pts uses the stream/packet timebase,

124 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
125 Moved codecpar field from AVStream to the end of the struct, so that
126 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
128 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h

133 Fix accidental ABI breakage in AVFilterContext.
134 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
136 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
137 compatible with lavfi>=6.47.100. Potentially also affects other users of
138 libavfilter if they are using one of the affected fields.
140 -------- 8< --------- FFmpeg 3.1 was cut here -------- 8< ---------
142 2016-06-26 - 481f320 / 1c9e861 - lavu 55.27.100 / 55.13.0 - hwcontext.h

175 Add new installed header with VAAPI-specific hwcontext definitions.
177 2016-04-14 - afccfaf / b1f01e8 - lavu 55.21.100 / 55.7.0 - hwcontext.h
178 Add AVHWFramesConstraints and associated API.
180 2016-04-11 - 6f69f7a / 9200514 - lavf 57.33.100 / 57.5.0 - avformat.h

191 Add requirement to bitstream filtering API that returned packets with
192 size == 0 and side_data_elems == 0 are to be skipped by the caller.
194 2016-03-04 - 9362973 - lavf 57.28.100
195 Add protocol blacklisting API
197 2016-02-28 - 4dd4d53 - lavc 57.27.101
198 Validate AVFrame returned by get_buffer2 to have required
199 planes not NULL and unused planes set to NULL as crashes
200 and buffer overflow are possible with certain streams if
201 that is not the case.
203 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
204 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
205 the reset of the ASS ReadOrder field on flush. This affects the content of
206 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
209 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
210 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
211 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
212 The default value for this option will change to "ass" at the next major
213 libavcodec version bump.
215 The current default is "ass_with_timings" for compatibility. This means that
216 all subtitles text decoders currently still output ASS with timings printed
217 as strings in the AVSubtitles.rects[N]->ass fields.
219 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
220 timing is limited to a 1/100 time base, so this is relevant for any subtitles
221 format needing a bigger one), ease timing adjustments, and prevents the need
222 of removing the timing from the decoded string yourself. This form is also
223 known as "the Matroska form". The timing information (start time, duration)
224 can be found in the AVSubtitles fields.

2659 Add a pts field to AVSubtitle which gives the subtitle packet pts
2660 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2661 not work right without this.
2663 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2664 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2665 major version. Use AV_PKT_FLAG_KEY instead.
2667 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2668 av_lockmgr_register() can be used to register a callback function
2669 that lavc (and in the future, libraries that depend on lavc) can use
2670 to implement mutexes. The application should provide a callback function
2671 that implements the AV_LOCK_* operations described in avcodec.h.
2672 When the lock manager is registered, FFmpeg is guaranteed to behave
2673 correctly in a multi-threaded application.
2675 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2676 av_free_packet() is no longer an inline function. It is now exported.
2678 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2679 Please use NULL instead. This has been supported since r16506
2680 (lavf > 52.23.1, lavc > 52.10.0).
2682 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2683 The old decoding functions are deprecated, all new code should use the
2684 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2685 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2686 argument instead of a const uint8_t *buf / int buf_size pair.
2688 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2689 Introduce the av_fifo_space() function.
2691 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2692 Move AVPacket declaration from libavformat/avformat.h to
2693 libavcodec/avcodec.h.
2695 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2696 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2697 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2698 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2699 PIX_FMT_BGR32_1 are now macros.
2700 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2701 Re-sort the enum PixelFormat list accordingly.
2702 This change breaks API/ABI backward compatibility.
2704 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2705 Add the enum PixelFormat values:
2706 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2707 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2709 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2710 The Mersenne Twister PRNG implemented through the av_random* functions
2711 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2714 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2715 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2716 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2717 and av_fifo_realloc2.
2718 In addition, the order of the function arguments of av_fifo_generic_read
2719 was changed to match av_fifo_generic_write.
2720 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2721 applications, they may not use sizeof() or directly access members.
2723 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2724 Introduce a new metadata API (see av_metadata_get() and friends).
2725 The old API is now deprecated and should not be used anymore. This especially
2726 includes the following structure fields:
2727 - AVFormatContext.title
2728 - AVFormatContext.author
2729 - AVFormatContext.copyright
2730 - AVFormatContext.comment
2731 - AVFormatContext.album
2732 - AVFormatContext.year
2733 - AVFormatContext.track
2734 - AVFormatContext.genre
2737 - AVProgram.provider_name
