167 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
168 (via an entry named "rotate"). Use av_stream_get_side_data() with
169 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
170 av_display_rotation_get(). The same is done for muxing. Instead of adding a
171 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has

199 Deprecate AVFilterGraph.resample_lavr_opts

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

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

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

2623 enum PixelFormat *formats -> int *formats in AVFilterFormats
2624 enum PixelFormat *format -> int format in AVFilterLink
2626 Change the function signatures:
2627 AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
2628 AVFilterFormats *avfilter_make_format_list(const int *fmts);
2630 int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
2631 int avfilter_add_format (AVFilterFormats **avff, int fmt);
2633 AVFilterFormats *avfilter_all_colorspaces(void); ->
2634 AVFilterFormats *avfilter_all_formats (enum AVMediaType type);
2636 This change breaks libavfilter API/ABI.

2827 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2828 Change the signature of avfilter_register() to make it return an
2829 int. This is required since now the registration operation may fail.
2831 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2832 Make the pixdesc.h API public.
2834 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2853 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2854 This is now an unsigned int instead of a signed int.
2856 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2857 Add a pts field to AVSubtitle which gives the subtitle packet pts
2858 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2859 not work right without this.
2861 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2862 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2863 major version. Use AV_PKT_FLAG_KEY instead.
2865 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2866 av_lockmgr_register() can be used to register a callback function
2867 that lavc (and in the future, libraries that depend on lavc) can use
2868 to implement mutexes. The application should provide a callback function
2869 that implements the AV_LOCK_* operations described in avcodec.h.
2870 When the lock manager is registered, FFmpeg is guaranteed to behave
2871 correctly in a multi-threaded application.
2873 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2874 av_free_packet() is no longer an inline function. It is now exported.
2876 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2877 Please use NULL instead. This has been supported since r16506
2878 (lavf > 52.23.1, lavc > 52.10.0).
2880 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2881 The old decoding functions are deprecated, all new code should use the
2882 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2883 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2884 argument instead of a const uint8_t *buf / int buf_size pair.
2886 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2887 Introduce the av_fifo_space() function.
2889 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2890 Move AVPacket declaration from libavformat/avformat.h to
2891 libavcodec/avcodec.h.
2893 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2894 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2895 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2896 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2897 PIX_FMT_BGR32_1 are now macros.
2898 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2899 Re-sort the enum PixelFormat list accordingly.
2900 This change breaks API/ABI backward compatibility.
2902 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2903 Add the enum PixelFormat values:
2904 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2905 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2907 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2908 The Mersenne Twister PRNG implemented through the av_random* functions
2909 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2912 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2913 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2914 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2915 and av_fifo_realloc2.
2916 In addition, the order of the function arguments of av_fifo_generic_read
2917 was changed to match av_fifo_generic_write.
2918 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2919 applications, they may not use sizeof() or directly access members.
2921 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2922 Introduce a new metadata API (see av_metadata_get() and friends).
2923 The old API is now deprecated and should not be used anymore. This especially
2924 includes the following structure fields:
2925 - AVFormatContext.title
2926 - AVFormatContext.author
2927 - AVFormatContext.copyright
2928 - AVFormatContext.comment
2929 - AVFormatContext.album
2930 - AVFormatContext.year
2931 - AVFormatContext.track
2932 - AVFormatContext.genre
2935 - AVProgram.provider_name
