112 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
113 Moved codecpar field from AVStream to the end of the struct, so that
114 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
116 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h

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

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

2660 When the lock manager is registered, FFmpeg is guaranteed to behave
2661 correctly in a multi-threaded application.
2663 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2664 av_free_packet() is no longer an inline function. It is now exported.
2666 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2667 Please use NULL instead. This has been supported since r16506
2668 (lavf > 52.23.1, lavc > 52.10.0).
2670 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2671 The old decoding functions are deprecated, all new code should use the
2672 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2673 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2674 argument instead of a const uint8_t *buf / int buf_size pair.
2676 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2677 Introduce the av_fifo_space() function.
2679 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2680 Move AVPacket declaration from libavformat/avformat.h to
2681 libavcodec/avcodec.h.
2683 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2684 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2685 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2686 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2687 PIX_FMT_BGR32_1 are now macros.
2688 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2689 Re-sort the enum PixelFormat list accordingly.
2690 This change breaks API/ABI backward compatibility.
2692 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2693 Add the enum PixelFormat values:
2694 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2695 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2697 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2698 The Mersenne Twister PRNG implemented through the av_random* functions
2699 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2702 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2703 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2704 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2705 and av_fifo_realloc2.
2706 In addition, the order of the function arguments of av_fifo_generic_read
2707 was changed to match av_fifo_generic_write.
2708 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2709 applications, they may not use sizeof() or directly access members.
2711 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2712 Introduce a new metadata API (see av_metadata_get() and friends).
2713 The old API is now deprecated and should not be used anymore. This especially
2714 includes the following structure fields:
2715 - AVFormatContext.title
2716 - AVFormatContext.author
2717 - AVFormatContext.copyright
2718 - AVFormatContext.comment
2719 - AVFormatContext.album
2720 - AVFormatContext.year
2721 - AVFormatContext.track
2722 - AVFormatContext.genre
2725 - AVProgram.provider_name
