134 Moved codecpar field from AVStream to the end of the struct, so that
135 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
137 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h

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

200 Add requirement to bitstream filtering API that returned packets with
201 size == 0 and side_data_elems == 0 are to be skipped by the caller.
203 2016-03-04 - 9362973 - lavf 57.28.100
204 Add protocol blacklisting API

207 Validate AVFrame returned by get_buffer2 to have required
208 planes not NULL and unused planes set to NULL as crashes
209 and buffer overflow are possible with certain streams if
210 that is not the case.
212 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
213 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
214 the reset of the ASS ReadOrder field on flush. This affects the content of
215 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
218 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
219 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
220 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
221 The default value for this option will change to "ass" at the next major
222 libavcodec version bump.
224 The current default is "ass_with_timings" for compatibility. This means that
225 all subtitles text decoders currently still output ASS with timings printed
226 as strings in the AVSubtitles.rects[N]->ass fields.
228 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
229 timing is limited to a 1/100 time base, so this is relevant for any subtitles
230 format needing a bigger one), ease timing adjustments, and prevents the need
231 of removing the timing from the decoded string yourself. This form is also
232 known as "the Matroska form". The timing information (start time, duration)
233 can be found in the AVSubtitles fields.

2661 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
2662 Add w and h fields to AVFilterPic.
2664 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2665 This is now an unsigned int instead of a signed int.
2667 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2668 Add a pts field to AVSubtitle which gives the subtitle packet pts
2669 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2670 not work right without this.
2672 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2673 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2674 major version. Use AV_PKT_FLAG_KEY instead.
2676 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2677 av_lockmgr_register() can be used to register a callback function
2678 that lavc (and in the future, libraries that depend on lavc) can use
2679 to implement mutexes. The application should provide a callback function
2680 that implements the AV_LOCK_* operations described in avcodec.h.
2681 When the lock manager is registered, FFmpeg is guaranteed to behave
2682 correctly in a multi-threaded application.
2684 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2685 av_free_packet() is no longer an inline function. It is now exported.
2687 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2688 Please use NULL instead. This has been supported since r16506
2689 (lavf > 52.23.1, lavc > 52.10.0).
2691 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2692 The old decoding functions are deprecated, all new code should use the
2693 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2694 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2695 argument instead of a const uint8_t *buf / int buf_size pair.
2697 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2698 Introduce the av_fifo_space() function.
2700 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2701 Move AVPacket declaration from libavformat/avformat.h to
2702 libavcodec/avcodec.h.
2704 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2705 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2706 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2707 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2708 PIX_FMT_BGR32_1 are now macros.
2709 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2710 Re-sort the enum PixelFormat list accordingly.
2711 This change breaks API/ABI backward compatibility.
2713 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2714 Add the enum PixelFormat values:
2715 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2716 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2718 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2719 The Mersenne Twister PRNG implemented through the av_random* functions
2720 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2723 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2724 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2725 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2726 and av_fifo_realloc2.
2727 In addition, the order of the function arguments of av_fifo_generic_read
2728 was changed to match av_fifo_generic_write.
2729 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2730 applications, they may not use sizeof() or directly access members.
2732 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2733 Introduce a new metadata API (see av_metadata_get() and friends).
2734 The old API is now deprecated and should not be used anymore. This especially
2735 includes the following structure fields:
2736 - AVFormatContext.title
2737 - AVFormatContext.author
2738 - AVFormatContext.copyright
2739 - AVFormatContext.comment
2740 - AVFormatContext.album
2741 - AVFormatContext.year
2742 - AVFormatContext.track
2743 - AVFormatContext.genre
2746 - AVProgram.provider_name
