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

197 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
198 bump, and libavformat will behave as if it were always set.
199 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().
201 2016-03-20 - 8200b16a9c - lavu 55.50.100 / 55.21.0 - imgutils.h

209 Deprecate AVFilterGraph.resample_lavr_opts

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

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

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

2620 Deprecate av_parse_video_frame_size() and av_parse_video_frame_rate()

2631 Change the field types:
2632 enum PixelFormat format -> int format in AVFilterBuffer
2633 enum PixelFormat *formats -> int *formats in AVFilterFormats
2634 enum PixelFormat *format -> int format in AVFilterLink
2636 Change the function signatures:
2637 AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
2638 AVFilterFormats *avfilter_make_format_list(const int *fmts);
2640 int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
2641 int avfilter_add_format (AVFilterFormats **avff, int fmt);
2643 AVFilterFormats *avfilter_all_colorspaces(void); ->
2644 AVFilterFormats *avfilter_all_formats (enum AVMediaType type);
2646 This change breaks libavfilter API/ABI.

2834 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2835 Introduce the avfilter_next() function.
2837 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2838 Change the signature of avfilter_register() to make it return an
2839 int. This is required since now the registration operation may fail.
2841 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2842 Make the pixdesc.h API public.
2844 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2861 Add w and h fields to AVFilterPic.
2863 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2864 This is now an unsigned int instead of a signed int.
2866 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2867 Add a pts field to AVSubtitle which gives the subtitle packet pts
2868 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2869 not work right without this.
2871 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2872 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2873 major version. Use AV_PKT_FLAG_KEY instead.
2875 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2876 av_lockmgr_register() can be used to register a callback function
2877 that lavc (and in the future, libraries that depend on lavc) can use
2878 to implement mutexes. The application should provide a callback function
2879 that implements the AV_LOCK_* operations described in avcodec.h.
2880 When the lock manager is registered, FFmpeg is guaranteed to behave
2881 correctly in a multi-threaded application.
2883 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2884 av_free_packet() is no longer an inline function. It is now exported.
2886 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2887 Please use NULL instead. This has been supported since r16506
2888 (lavf > 52.23.1, lavc > 52.10.0).
2890 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2891 The old decoding functions are deprecated, all new code should use the
2892 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2893 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2894 argument instead of a const uint8_t *buf / int buf_size pair.
2896 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2897 Introduce the av_fifo_space() function.
2899 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2900 Move AVPacket declaration from libavformat/avformat.h to
2901 libavcodec/avcodec.h.
2903 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2904 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2905 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2906 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2907 PIX_FMT_BGR32_1 are now macros.
2908 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2909 Re-sort the enum PixelFormat list accordingly.
2910 This change breaks API/ABI backward compatibility.
2912 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2913 Add the enum PixelFormat values:
2914 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2915 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2917 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2918 The Mersenne Twister PRNG implemented through the av_random* functions
2919 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2922 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2923 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2924 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2925 and av_fifo_realloc2.
2926 In addition, the order of the function arguments of av_fifo_generic_read
2927 was changed to match av_fifo_generic_write.
2928 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2929 applications, they may not use sizeof() or directly access members.
2931 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2932 Introduce a new metadata API (see av_metadata_get() and friends).
2933 The old API is now deprecated and should not be used anymore. This especially
2934 includes the following structure fields:
2935 - AVFormatContext.title
2936 - AVFormatContext.author
2937 - AVFormatContext.copyright
2938 - AVFormatContext.comment
2939 - AVFormatContext.album
2940 - AVFormatContext.year
2941 - AVFormatContext.track
2942 - AVFormatContext.genre
2945 - AVProgram.provider_name
