121 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
122 Moved codecpar field from AVStream to the end of the struct, so that
123 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
125 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h

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

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

2661 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2662 major version. Use AV_PKT_FLAG_KEY instead.
2664 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2665 av_lockmgr_register() can be used to register a callback function
2666 that lavc (and in the future, libraries that depend on lavc) can use
2667 to implement mutexes. The application should provide a callback function
2668 that implements the AV_LOCK_* operations described in avcodec.h.
2669 When the lock manager is registered, FFmpeg is guaranteed to behave
2670 correctly in a multi-threaded application.
2672 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2673 av_free_packet() is no longer an inline function. It is now exported.
2675 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2676 Please use NULL instead. This has been supported since r16506
2677 (lavf > 52.23.1, lavc > 52.10.0).
2679 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2680 The old decoding functions are deprecated, all new code should use the
2681 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2682 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2683 argument instead of a const uint8_t *buf / int buf_size pair.
2685 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2686 Introduce the av_fifo_space() function.
2688 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2689 Move AVPacket declaration from libavformat/avformat.h to
2690 libavcodec/avcodec.h.
2692 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2693 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2694 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2695 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2696 PIX_FMT_BGR32_1 are now macros.
2697 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2698 Re-sort the enum PixelFormat list accordingly.
2699 This change breaks API/ABI backward compatibility.
2701 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2702 Add the enum PixelFormat values:
2703 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2704 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2706 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2707 The Mersenne Twister PRNG implemented through the av_random* functions
2708 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2711 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2712 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2713 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2714 and av_fifo_realloc2.
2715 In addition, the order of the function arguments of av_fifo_generic_read
2716 was changed to match av_fifo_generic_write.
2717 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2718 applications, they may not use sizeof() or directly access members.
2720 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2721 Introduce a new metadata API (see av_metadata_get() and friends).
2722 The old API is now deprecated and should not be used anymore. This especially
2723 includes the following structure fields:
2724 - AVFormatContext.title
2725 - AVFormatContext.author
2726 - AVFormatContext.copyright
2727 - AVFormatContext.comment
2728 - AVFormatContext.album
2729 - AVFormatContext.year
2730 - AVFormatContext.track
2731 - AVFormatContext.genre
2734 - AVProgram.provider_name
