82 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
83 Moved codecpar field from AVStream to the end of the struct, so that
84 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
86 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
87 Moved hw_frames_ctx field from AVFrame to the end of the struct, so that

90 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
91 Fix accidental ABI breakage in AVFilterContext.
92 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
94 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
95 compatible with lavfi>=6.47.100. Potentially also affects other users of
96 libavfilter if they are using one of the affected fields.

149 Add requirement to bitstream filtering API that returned packets with
150 size == 0 and side_data_elems == 0 are to be skipped by the caller.
152 2016-03-04 - 9362973 - lavf 57.28.100

158 and buffer overflow are possible with certain streams if
159 that is not the case.
161 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
162 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
163 the reset of the ASS ReadOrder field on flush. This affects the content of
164 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
167 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
168 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
169 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
170 The default value for this option will change to "ass" at the next major
171 libavcodec version bump.
173 The current default is "ass_with_timings" for compatibility. This means that
174 all subtitles text decoders currently still output ASS with timings printed
175 as strings in the AVSubtitles.rects[N]->ass fields.
177 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
178 timing is limited to a 1/100 time base, so this is relevant for any subtitles
179 format needing a bigger one), ease timing adjustments, and prevents the need
180 of removing the timing from the decoded string yourself. This form is also
181 known as "the Matroska form". The timing information (start time, duration)
182 can be found in the AVSubtitles fields.

2656 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2657 PIX_FMT_BGR32_1 are now macros.
2658 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2659 Re-sort the enum PixelFormat list accordingly.
2660 This change breaks API/ABI backward compatibility.
2662 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2663 Add the enum PixelFormat values:
2664 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2665 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2667 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2668 The Mersenne Twister PRNG implemented through the av_random* functions
2669 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2672 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2673 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2674 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2675 and av_fifo_realloc2.
2676 In addition, the order of the function arguments of av_fifo_generic_read
2677 was changed to match av_fifo_generic_write.
2678 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2679 applications, they may not use sizeof() or directly access members.
2681 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2682 Introduce a new metadata API (see av_metadata_get() and friends).
2683 The old API is now deprecated and should not be used anymore. This especially
2684 includes the following structure fields:
2685 - AVFormatContext.title
2686 - AVFormatContext.author
2687 - AVFormatContext.copyright
2688 - AVFormatContext.comment
2689 - AVFormatContext.album
2690 - AVFormatContext.year
2691 - AVFormatContext.track
2692 - AVFormatContext.genre
2695 - AVProgram.provider_name
