192 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
193 (via an entry named "rotate"). Use av_stream_get_side_data() with

195 av_display_rotation_get(). The same is done for muxing. Instead of adding a
196 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has

212 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
213 bump, and libavformat will behave as if it were always set.
214 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().
216 2016-03-20 - 8200b16a9c - lavu 55.50.100 / 55.21.0 - imgutils.h

221 Add AV_PIX_FMT_FLAG_BAYER pixel format flag.
223 2017-03-18 - 3796fb2692 - lavfi 6.77.100 - avfilter.h
224 Deprecate AVFilterGraph.resample_lavr_opts

233 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
234 native decoder format. (The default value is not changed.)

237 Remove requirement to use AVOption or accessors to access certain fields
238 in AVFrame, AVCodecContext, and AVFormatContext that were previously
239 documented as "no direct access" allowed.

302 Decoders now export the frame timestamp as AVFrame.pts. It was
303 previously exported as AVFrame.pkt_pts, which is now deprecated.

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

426 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
427 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
428 the reset of the ASS ReadOrder field on flush. This affects the content of
429 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
432 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
433 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
434 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
435 The default value for this option will change to "ass" at the next major
436 libavcodec version bump.
438 The current default is "ass_with_timings" for compatibility. This means that
439 all subtitles text decoders currently still output ASS with timings printed
440 as strings in the AVSubtitles.rects[N]->ass fields.
442 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
443 timing is limited to a 1/100 time base, so this is relevant for any subtitles
444 format needing a bigger one), ease timing adjustments, and prevents the need
445 of removing the timing from the decoded string yourself. This form is also
446 known as "the Matroska form". The timing information (start time, duration)
447 can be found in the AVSubtitles fields.

2849 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2850 Introduce the avfilter_next() function.
2852 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2853 Change the signature of avfilter_register() to make it return an
2854 int. This is required since now the registration operation may fail.
2856 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2857 Make the pixdesc.h API public.
2859 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2876 Add w and h fields to AVFilterPic.
2878 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2879 This is now an unsigned int instead of a signed int.
2881 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2882 Add a pts field to AVSubtitle which gives the subtitle packet pts
2883 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2884 not work right without this.
2886 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2887 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2888 major version. Use AV_PKT_FLAG_KEY instead.
2890 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2891 av_lockmgr_register() can be used to register a callback function
2892 that lavc (and in the future, libraries that depend on lavc) can use
2893 to implement mutexes. The application should provide a callback function
2894 that implements the AV_LOCK_* operations described in avcodec.h.
2895 When the lock manager is registered, FFmpeg is guaranteed to behave
2896 correctly in a multi-threaded application.
2898 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2899 av_free_packet() is no longer an inline function. It is now exported.
2901 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2902 Please use NULL instead. This has been supported since r16506
2903 (lavf > 52.23.1, lavc > 52.10.0).
2905 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2906 The old decoding functions are deprecated, all new code should use the
2907 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2908 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2909 argument instead of a const uint8_t *buf / int buf_size pair.
2911 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2912 Introduce the av_fifo_space() function.
2914 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2915 Move AVPacket declaration from libavformat/avformat.h to
2916 libavcodec/avcodec.h.
2918 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2919 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2920 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2921 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2922 PIX_FMT_BGR32_1 are now macros.
2923 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2924 Re-sort the enum PixelFormat list accordingly.
2925 This change breaks API/ABI backward compatibility.
2927 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2928 Add the enum PixelFormat values:
2929 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2930 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2932 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2933 The Mersenne Twister PRNG implemented through the av_random* functions
2934 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2937 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2938 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2939 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2940 and av_fifo_realloc2.
2941 In addition, the order of the function arguments of av_fifo_generic_read
2942 was changed to match av_fifo_generic_write.
2943 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2944 applications, they may not use sizeof() or directly access members.
2946 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2947 Introduce a new metadata API (see av_metadata_get() and friends).
2948 The old API is now deprecated and should not be used anymore. This especially
2949 includes the following structure fields:
2950 - AVFormatContext.title
2951 - AVFormatContext.author
2952 - AVFormatContext.copyright
2953 - AVFormatContext.comment
2954 - AVFormatContext.album
2955 - AVFormatContext.year
2956 - AVFormatContext.track
2957 - AVFormatContext.genre
2960 - AVProgram.provider_name
