160 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
161 (via an entry named "rotate"). Use av_stream_get_side_data() with
162 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
163 av_display_rotation_get(). The same is done for muxing. Instead of adding a
164 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
165 to be added to the AVStream.

180 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
181 bump, and libavformat will behave as if it were always set.

192 Deprecate AVFilterGraph.resample_lavr_opts

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

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

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

395 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
396 the reset of the ASS ReadOrder field on flush. This affects the content of
397 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
400 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
401 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
402 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
403 The default value for this option will change to "ass" at the next major
404 libavcodec version bump.
406 The current default is "ass_with_timings" for compatibility. This means that
407 all subtitles text decoders currently still output ASS with timings printed
408 as strings in the AVSubtitles.rects[N]->ass fields.
410 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
411 timing is limited to a 1/100 time base, so this is relevant for any subtitles
412 format needing a bigger one), ease timing adjustments, and prevents the need
413 of removing the timing from the decoded string yourself. This form is also
414 known as "the Matroska form". The timing information (start time, duration)
415 can be found in the AVSubtitles fields.

1501 reget_buffer(), avcodec_default_get_buffer(),
1502 avcodec_default_reget_buffer(), avcodec_default_release_buffer().
1503 Remove avcodec_default_free_buffers(), which should not have ever
1504 been called from outside of lavc.
1505 Deprecate the following AVFrame fields:
1506 * base -- is now stored in AVBufferRef
1507 * reference, type, buffer_hints -- are unnecessary in the new API
1508 * hwaccel_picture_private, owner, thread_opaque -- should not
1509 have been accessed from outside of lavc
1510 * qscale_table, qstride, qscale_type, mbskip_table, motion_val,

1669 For audio formats with fixed frame size, the last frame

2821 Change the signature of avfilter_register() to make it return an
2822 int. This is required since now the registration operation may fail.
2824 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2825 Make the pixdesc.h API public.

2849 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2850 Add a pts field to AVSubtitle which gives the subtitle packet pts
2851 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2852 not work right without this.
2854 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2855 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2856 major version. Use AV_PKT_FLAG_KEY instead.
2858 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2859 av_lockmgr_register() can be used to register a callback function
2860 that lavc (and in the future, libraries that depend on lavc) can use
2861 to implement mutexes. The application should provide a callback function
2862 that implements the AV_LOCK_* operations described in avcodec.h.
2863 When the lock manager is registered, FFmpeg is guaranteed to behave
2864 correctly in a multi-threaded application.
2866 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2867 av_free_packet() is no longer an inline function. It is now exported.
2869 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2870 Please use NULL instead. This has been supported since r16506
2871 (lavf > 52.23.1, lavc > 52.10.0).
2873 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2874 The old decoding functions are deprecated, all new code should use the
2875 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2876 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2877 argument instead of a const uint8_t *buf / int buf_size pair.
2879 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2880 Introduce the av_fifo_space() function.
2882 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2883 Move AVPacket declaration from libavformat/avformat.h to
2884 libavcodec/avcodec.h.
2886 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2887 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2888 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2889 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2890 PIX_FMT_BGR32_1 are now macros.
2891 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2892 Re-sort the enum PixelFormat list accordingly.
2893 This change breaks API/ABI backward compatibility.
2895 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2896 Add the enum PixelFormat values:
2897 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2898 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2900 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2901 The Mersenne Twister PRNG implemented through the av_random* functions
2902 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2905 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2906 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2907 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2908 and av_fifo_realloc2.
2909 In addition, the order of the function arguments of av_fifo_generic_read
2910 was changed to match av_fifo_generic_write.
2911 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2912 applications, they may not use sizeof() or directly access members.
2914 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2915 Introduce a new metadata API (see av_metadata_get() and friends).
2916 The old API is now deprecated and should not be used anymore. This especially
2917 includes the following structure fields:
2918 - AVFormatContext.title
2919 - AVFormatContext.author
2920 - AVFormatContext.copyright
2921 - AVFormatContext.comment
2922 - AVFormatContext.album
2923 - AVFormatContext.year
2924 - AVFormatContext.track
2925 - AVFormatContext.genre
2928 - AVProgram.provider_name
