130 Moved codecpar field from AVStream to the end of the struct, so that
131 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
133 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h

138 Fix accidental ABI breakage in AVFilterContext.
139 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
141 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
142 compatible with lavfi>=6.47.100. Potentially also affects other users of
143 libavfilter if they are using one of the affected fields.
145 -------- 8< --------- FFmpeg 3.1 was cut here -------- 8< ---------

182 2016-04-14 - afccfaf / b1f01e8 - lavu 55.21.100 / 55.7.0 - hwcontext.h
183 Add AVHWFramesConstraints and associated API.
185 2016-04-11 - 6f69f7a / 9200514 - lavf 57.33.100 / 57.5.0 - avformat.h

196 Add requirement to bitstream filtering API that returned packets with
197 size == 0 and side_data_elems == 0 are to be skipped by the caller.
199 2016-03-04 - 9362973 - lavf 57.28.100
200 Add protocol blacklisting API
202 2016-02-28 - 4dd4d53 - lavc 57.27.101
203 Validate AVFrame returned by get_buffer2 to have required
204 planes not NULL and unused planes set to NULL as crashes
205 and buffer overflow are possible with certain streams if
206 that is not the case.
208 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
209 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
210 the reset of the ASS ReadOrder field on flush. This affects the content of
211 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
214 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
215 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
216 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
217 The default value for this option will change to "ass" at the next major
218 libavcodec version bump.
220 The current default is "ass_with_timings" for compatibility. This means that
221 all subtitles text decoders currently still output ASS with timings printed
222 as strings in the AVSubtitles.rects[N]->ass fields.
224 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
225 timing is limited to a 1/100 time base, so this is relevant for any subtitles
226 format needing a bigger one), ease timing adjustments, and prevents the need
227 of removing the timing from the decoded string yourself. This form is also
228 known as "the Matroska form". The timing information (start time, duration)
229 can be found in the AVSubtitles fields.

2660 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2661 This is now an unsigned int instead of a signed int.
2663 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2664 Add a pts field to AVSubtitle which gives the subtitle packet pts
2665 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2666 not work right without this.
2668 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2669 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2670 major version. Use AV_PKT_FLAG_KEY instead.
2672 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2673 av_lockmgr_register() can be used to register a callback function
2674 that lavc (and in the future, libraries that depend on lavc) can use
2675 to implement mutexes. The application should provide a callback function
2676 that implements the AV_LOCK_* operations described in avcodec.h.
2677 When the lock manager is registered, FFmpeg is guaranteed to behave
2678 correctly in a multi-threaded application.
2680 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2681 av_free_packet() is no longer an inline function. It is now exported.
2683 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2684 Please use NULL instead. This has been supported since r16506
2685 (lavf > 52.23.1, lavc > 52.10.0).
2687 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2688 The old decoding functions are deprecated, all new code should use the
2689 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2690 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2691 argument instead of a const uint8_t *buf / int buf_size pair.
2693 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2694 Introduce the av_fifo_space() function.
2696 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2697 Move AVPacket declaration from libavformat/avformat.h to
2698 libavcodec/avcodec.h.
2700 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2701 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2702 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2703 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2704 PIX_FMT_BGR32_1 are now macros.
2705 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2706 Re-sort the enum PixelFormat list accordingly.
2707 This change breaks API/ABI backward compatibility.
2709 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2710 Add the enum PixelFormat values:
2711 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2712 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2714 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2715 The Mersenne Twister PRNG implemented through the av_random* functions
2716 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2719 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2720 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2721 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2722 and av_fifo_realloc2.
2723 In addition, the order of the function arguments of av_fifo_generic_read
2724 was changed to match av_fifo_generic_write.
2725 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2726 applications, they may not use sizeof() or directly access members.
2728 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2729 Introduce a new metadata API (see av_metadata_get() and friends).
2730 The old API is now deprecated and should not be used anymore. This especially
2731 includes the following structure fields:
2732 - AVFormatContext.title
2733 - AVFormatContext.author
2734 - AVFormatContext.copyright
2735 - AVFormatContext.comment
2736 - AVFormatContext.album
2737 - AVFormatContext.year
2738 - AVFormatContext.track
2739 - AVFormatContext.genre
2742 - AVProgram.provider_name
