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

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

350 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
351 Fix accidental ABI breakage in AVFilterContext.
352 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
354 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
355 compatible with lavfi>=6.47.100. Potentially also affects other users of
356 libavfilter if they are using one of the affected fields.

421 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
422 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
423 the reset of the ASS ReadOrder field on flush. This affects the content of
424 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
427 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
428 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
429 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
430 The default value for this option will change to "ass" at the next major
431 libavcodec version bump.
433 The current default is "ass_with_timings" for compatibility. This means that
434 all subtitles text decoders currently still output ASS with timings printed
435 as strings in the AVSubtitles.rects[N]->ass fields.
437 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
438 timing is limited to a 1/100 time base, so this is relevant for any subtitles
439 format needing a bigger one), ease timing adjustments, and prevents the need
440 of removing the timing from the decoded string yourself. This form is also
441 known as "the Matroska form". The timing information (start time, duration)
442 can be found in the AVSubtitles fields.

2644 enum PixelFormat *format -> int format in AVFilterLink
2646 Change the function signatures:
2647 AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
2648 AVFilterFormats *avfilter_make_format_list(const int *fmts);
2650 int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
2651 int avfilter_add_format (AVFilterFormats **avff, int fmt);
2653 AVFilterFormats *avfilter_all_colorspaces(void); ->
2654 AVFilterFormats *avfilter_all_formats (enum AVMediaType type);

2847 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2848 Change the signature of avfilter_register() to make it return an
2849 int. This is required since now the registration operation may fail.
2851 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2852 Make the pixdesc.h API public.

2871 Add w and h fields to AVFilterPic.
2873 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2874 This is now an unsigned int instead of a signed int.
2876 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2877 Add a pts field to AVSubtitle which gives the subtitle packet pts
2878 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2879 not work right without this.
2881 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2882 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2883 major version. Use AV_PKT_FLAG_KEY instead.
2885 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2886 av_lockmgr_register() can be used to register a callback function
2887 that lavc (and in the future, libraries that depend on lavc) can use
2888 to implement mutexes. The application should provide a callback function
2889 that implements the AV_LOCK_* operations described in avcodec.h.
2890 When the lock manager is registered, FFmpeg is guaranteed to behave
2891 correctly in a multi-threaded application.
2893 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2894 av_free_packet() is no longer an inline function. It is now exported.
2896 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2897 Please use NULL instead. This has been supported since r16506
2898 (lavf > 52.23.1, lavc > 52.10.0).
2900 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2901 The old decoding functions are deprecated, all new code should use the
2902 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2903 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2904 argument instead of a const uint8_t *buf / int buf_size pair.
2906 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2907 Introduce the av_fifo_space() function.
2909 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2910 Move AVPacket declaration from libavformat/avformat.h to
2911 libavcodec/avcodec.h.
2913 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2914 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2915 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2916 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2917 PIX_FMT_BGR32_1 are now macros.
2918 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2919 Re-sort the enum PixelFormat list accordingly.
2920 This change breaks API/ABI backward compatibility.
2922 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2923 Add the enum PixelFormat values:
2924 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2925 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2927 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2928 The Mersenne Twister PRNG implemented through the av_random* functions
2929 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2932 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2933 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2934 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2935 and av_fifo_realloc2.
2936 In addition, the order of the function arguments of av_fifo_generic_read
2937 was changed to match av_fifo_generic_write.
2938 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2939 applications, they may not use sizeof() or directly access members.
2941 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2942 Introduce a new metadata API (see av_metadata_get() and friends).
2943 The old API is now deprecated and should not be used anymore. This especially
2944 includes the following structure fields:
2945 - AVFormatContext.title
2946 - AVFormatContext.author
2947 - AVFormatContext.copyright
2948 - AVFormatContext.comment
2949 - AVFormatContext.album
2950 - AVFormatContext.year
2951 - AVFormatContext.track
2952 - AVFormatContext.genre
2955 - AVProgram.provider_name
