145 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes

147 set the Cuda device handle.
149 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

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

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

205 Deprecate AVFilterGraph.resample_lavr_opts

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

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

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

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

2617 defined in libavcodec in favor of the newly added functions
2618 av_parse_video_size() and av_parse_video_rate() declared in
2619 libavcore/parseutils.h.

2624 2010-07-22 - bdab614 - lavfi 1.26.0 - media format generalization
2625 Add a type field to AVFilterLink.
2627 Change the field types:
2628 enum PixelFormat format -> int format in AVFilterBuffer
2629 enum PixelFormat *formats -> int *formats in AVFilterFormats
2630 enum PixelFormat *format -> int format in AVFilterLink
2632 Change the function signatures:
2633 AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
2634 AVFilterFormats *avfilter_make_format_list(const int *fmts);
2636 int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
2637 int avfilter_add_format (AVFilterFormats **avff, int fmt);
2639 AVFilterFormats *avfilter_all_colorspaces(void); ->
2640 AVFilterFormats *avfilter_all_formats (enum AVMediaType type);
2642 This change breaks libavfilter API/ABI.

2830 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2831 Introduce the avfilter_next() function.
2833 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2834 Change the signature of avfilter_register() to make it return an
2835 int. This is required since now the registration operation may fail.
2837 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2838 Make the pixdesc.h API public.
2840 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2857 Add w and h fields to AVFilterPic.
2859 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2860 This is now an unsigned int instead of a signed int.
2862 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2863 Add a pts field to AVSubtitle which gives the subtitle packet pts
2864 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2865 not work right without this.
2867 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2868 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2869 major version. Use AV_PKT_FLAG_KEY instead.
2871 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2872 av_lockmgr_register() can be used to register a callback function
2873 that lavc (and in the future, libraries that depend on lavc) can use
2874 to implement mutexes. The application should provide a callback function
2875 that implements the AV_LOCK_* operations described in avcodec.h.
2876 When the lock manager is registered, FFmpeg is guaranteed to behave
2877 correctly in a multi-threaded application.
2879 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2880 av_free_packet() is no longer an inline function. It is now exported.
2882 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2883 Please use NULL instead. This has been supported since r16506
2884 (lavf > 52.23.1, lavc > 52.10.0).
2886 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2887 The old decoding functions are deprecated, all new code should use the
2888 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2889 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2890 argument instead of a const uint8_t *buf / int buf_size pair.
2892 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2893 Introduce the av_fifo_space() function.
2895 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2896 Move AVPacket declaration from libavformat/avformat.h to
2897 libavcodec/avcodec.h.
2899 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2900 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2901 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2902 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2903 PIX_FMT_BGR32_1 are now macros.
2904 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2905 Re-sort the enum PixelFormat list accordingly.
2906 This change breaks API/ABI backward compatibility.
2908 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2909 Add the enum PixelFormat values:
2910 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2911 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2913 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2914 The Mersenne Twister PRNG implemented through the av_random* functions
2915 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2918 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2919 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2920 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2921 and av_fifo_realloc2.
2922 In addition, the order of the function arguments of av_fifo_generic_read
2923 was changed to match av_fifo_generic_write.
2924 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2925 applications, they may not use sizeof() or directly access members.
2927 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2928 Introduce a new metadata API (see av_metadata_get() and friends).
2929 The old API is now deprecated and should not be used anymore. This especially
2930 includes the following structure fields:
2931 - AVFormatContext.title
2932 - AVFormatContext.author
2933 - AVFormatContext.copyright
2934 - AVFormatContext.comment
2935 - AVFormatContext.album
2936 - AVFormatContext.year
2937 - AVFormatContext.track
2938 - AVFormatContext.genre
2941 - AVProgram.provider_name
