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

124 Fix accidental ABI breakage in AVFilterContext.
125 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
127 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
128 compatible with lavfi>=6.47.100. Potentially also affects other users of
129 libavfilter if they are using one of the affected fields.

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

2659 av_lockmgr_register() can be used to register a callback function
2660 that lavc (and in the future, libraries that depend on lavc) can use
2661 to implement mutexes. The application should provide a callback function
2662 that implements the AV_LOCK_* operations described in avcodec.h.
2663 When the lock manager is registered, FFmpeg is guaranteed to behave
2664 correctly in a multi-threaded application.
2666 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2667 av_free_packet() is no longer an inline function. It is now exported.
2669 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2670 Please use NULL instead. This has been supported since r16506
2671 (lavf > 52.23.1, lavc > 52.10.0).
2673 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2674 The old decoding functions are deprecated, all new code should use the
2675 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2676 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2677 argument instead of a const uint8_t *buf / int buf_size pair.
2679 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2680 Introduce the av_fifo_space() function.
2682 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2683 Move AVPacket declaration from libavformat/avformat.h to
2684 libavcodec/avcodec.h.
2686 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2687 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2688 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2689 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2690 PIX_FMT_BGR32_1 are now macros.
2691 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2692 Re-sort the enum PixelFormat list accordingly.
2693 This change breaks API/ABI backward compatibility.
2695 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2696 Add the enum PixelFormat values:
2697 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2698 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2700 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2701 The Mersenne Twister PRNG implemented through the av_random* functions
2702 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2705 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2706 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2707 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2708 and av_fifo_realloc2.
2709 In addition, the order of the function arguments of av_fifo_generic_read
2710 was changed to match av_fifo_generic_write.
2711 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2712 applications, they may not use sizeof() or directly access members.
2714 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2715 Introduce a new metadata API (see av_metadata_get() and friends).
2716 The old API is now deprecated and should not be used anymore. This especially
2717 includes the following structure fields:
2718 - AVFormatContext.title
2719 - AVFormatContext.author
2720 - AVFormatContext.copyright
2721 - AVFormatContext.comment
2722 - AVFormatContext.album
2723 - AVFormatContext.year
2724 - AVFormatContext.track
2725 - AVFormatContext.genre
2728 - AVProgram.provider_name
