73 2016-08-15 - b746ed7 - lavc 57.52.100 - avcodec.h
74 Add a new API for chained BSF filters and passthrough (null) BSF --

85 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
86 Moved codecpar field from AVStream to the end of the struct, so that
87 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
89 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
90 Moved hw_frames_ctx field from AVFrame to the end of the struct, so that
91 the following private fields are in the same location as in FFmpeg 3.0 (lavu 55.17.103).
93 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
94 Fix accidental ABI breakage in AVFilterContext.
95 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
97 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
98 compatible with lavfi>=6.47.100. Potentially also affects other users of
99 libavfilter if they are using one of the affected fields.

152 Add requirement to bitstream filtering API that returned packets with
153 size == 0 and side_data_elems == 0 are to be skipped by the caller.
155 2016-03-04 - 9362973 - lavf 57.28.100

159 Validate AVFrame returned by get_buffer2 to have required
160 planes not NULL and unused planes set to NULL as crashes
161 and buffer overflow are possible with certain streams if
162 that is not the case.
164 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
165 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
166 the reset of the ASS ReadOrder field on flush. This affects the content of
167 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
170 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
171 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
172 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
173 The default value for this option will change to "ass" at the next major
174 libavcodec version bump.
176 The current default is "ass_with_timings" for compatibility. This means that
177 all subtitles text decoders currently still output ASS with timings printed
178 as strings in the AVSubtitles.rects[N]->ass fields.
180 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
181 timing is limited to a 1/100 time base, so this is relevant for any subtitles
182 format needing a bigger one), ease timing adjustments, and prevents the need
183 of removing the timing from the decoded string yourself. This form is also
184 known as "the Matroska form". The timing information (start time, duration)
185 can be found in the AVSubtitles fields.

2659 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2660 PIX_FMT_BGR32_1 are now macros.
2661 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2662 Re-sort the enum PixelFormat list accordingly.
2663 This change breaks API/ABI backward compatibility.
2665 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2666 Add the enum PixelFormat values:
2667 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2668 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2670 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2671 The Mersenne Twister PRNG implemented through the av_random* functions
2672 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2675 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2676 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2677 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2678 and av_fifo_realloc2.
2679 In addition, the order of the function arguments of av_fifo_generic_read
2680 was changed to match av_fifo_generic_write.
2681 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2682 applications, they may not use sizeof() or directly access members.
2684 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2685 Introduce a new metadata API (see av_metadata_get() and friends).
2686 The old API is now deprecated and should not be used anymore. This especially
2687 includes the following structure fields:
2688 - AVFormatContext.title
2689 - AVFormatContext.author
2690 - AVFormatContext.copyright
2691 - AVFormatContext.comment
2692 - AVFormatContext.album
2693 - AVFormatContext.year
2694 - AVFormatContext.track
2695 - AVFormatContext.genre
2698 - AVProgram.provider_name
