76 Note: When decoding, AVFrame.pts uses the stream/packet timebase,

118 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
119 Moved codecpar field from AVStream to the end of the struct, so that
120 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
122 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h

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

169 Add new installed header with VAAPI-specific hwcontext definitions.
171 2016-04-14 - afccfaf / b1f01e8 - lavu 55.21.100 / 55.7.0 - hwcontext.h

182 e6053b3 / a806834 - Add av_get_audio_frame_duration2().
184 2016-03-11 - 6d8ab35 - lavf/lavc 57.28.101
185 Add requirement to bitstream filtering API that returned packets with
186 size == 0 and side_data_elems == 0 are to be skipped by the caller.
188 2016-03-04 - 9362973 - lavf 57.28.100
189 Add protocol blacklisting API
191 2016-02-28 - 4dd4d53 - lavc 57.27.101
192 Validate AVFrame returned by get_buffer2 to have required
193 planes not NULL and unused planes set to NULL as crashes
194 and buffer overflow are possible with certain streams if
195 that is not the case.
197 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
198 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
199 the reset of the ASS ReadOrder field on flush. This affects the content of
200 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
203 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
204 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
205 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
206 The default value for this option will change to "ass" at the next major
207 libavcodec version bump.
209 The current default is "ass_with_timings" for compatibility. This means that
210 all subtitles text decoders currently still output ASS with timings printed
211 as strings in the AVSubtitles.rects[N]->ass fields.
213 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
214 timing is limited to a 1/100 time base, so this is relevant for any subtitles
215 format needing a bigger one), ease timing adjustments, and prevents the need
216 of removing the timing from the decoded string yourself. This form is also
217 known as "the Matroska form". The timing information (start time, duration)
218 can be found in the AVSubtitles fields.

2662 av_lockmgr_register() can be used to register a callback function
2663 that lavc (and in the future, libraries that depend on lavc) can use
2664 to implement mutexes. The application should provide a callback function
2665 that implements the AV_LOCK_* operations described in avcodec.h.
2666 When the lock manager is registered, FFmpeg is guaranteed to behave
2667 correctly in a multi-threaded application.
2669 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2670 av_free_packet() is no longer an inline function. It is now exported.
2672 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2673 Please use NULL instead. This has been supported since r16506
2674 (lavf > 52.23.1, lavc > 52.10.0).
2676 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2677 The old decoding functions are deprecated, all new code should use the
2678 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2679 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2680 argument instead of a const uint8_t *buf / int buf_size pair.
2682 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2683 Introduce the av_fifo_space() function.
2685 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2686 Move AVPacket declaration from libavformat/avformat.h to
2687 libavcodec/avcodec.h.
2689 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2690 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2691 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2692 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2693 PIX_FMT_BGR32_1 are now macros.
2694 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2695 Re-sort the enum PixelFormat list accordingly.
2696 This change breaks API/ABI backward compatibility.
2698 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2699 Add the enum PixelFormat values:
2700 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2701 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2703 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2704 The Mersenne Twister PRNG implemented through the av_random* functions
2705 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2708 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2709 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2710 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2711 and av_fifo_realloc2.
2712 In addition, the order of the function arguments of av_fifo_generic_read
2713 was changed to match av_fifo_generic_write.
2714 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2715 applications, they may not use sizeof() or directly access members.
2717 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2718 Introduce a new metadata API (see av_metadata_get() and friends).
2719 The old API is now deprecated and should not be used anymore. This especially
2720 includes the following structure fields:
2721 - AVFormatContext.title
2722 - AVFormatContext.author
2723 - AVFormatContext.copyright
2724 - AVFormatContext.comment
2725 - AVFormatContext.album
2726 - AVFormatContext.year
2727 - AVFormatContext.track
2728 - AVFormatContext.genre
2731 - AVProgram.provider_name
