82 the new AV_PIX_FMT_D3D11 pixfmt must be used with the new API.

125 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
126 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
127 set the Cuda device handle.
129 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

153 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
154 (via an entry named "rotate"). Use av_stream_get_side_data() with
155 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
156 av_display_rotation_get(). The same is done for muxing. Instead of adding a
157 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
158 to be added to the AVStream.

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

194 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
195 native decoder format. (The default value is not changed.)
197 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103

199 in AVFrame, AVCodecContext, and AVFormatContext that were previously
200 documented as "no direct access" allowed.

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

375 Add requirement to bitstream filtering API that returned packets with
376 size == 0 and side_data_elems == 0 are to be skipped by the caller.

388 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
389 the reset of the ASS ReadOrder field on flush. This affects the content of
390 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
393 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
394 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
395 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
396 The default value for this option will change to "ass" at the next major
397 libavcodec version bump.
399 The current default is "ass_with_timings" for compatibility. This means that
400 all subtitles text decoders currently still output ASS with timings printed
401 as strings in the AVSubtitles.rects[N]->ass fields.
403 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
404 timing is limited to a 1/100 time base, so this is relevant for any subtitles
405 format needing a bigger one), ease timing adjustments, and prevents the need
406 of removing the timing from the decoded string yourself. This form is also
407 known as "the Matroska form". The timing information (start time, duration)
408 can be found in the AVSubtitles fields.

1494 reget_buffer(), avcodec_default_get_buffer(),
1495 avcodec_default_reget_buffer(), avcodec_default_release_buffer().
1496 Remove avcodec_default_free_buffers(), which should not have ever
1497 been called from outside of lavc.
1498 Deprecate the following AVFrame fields:
1499 * base -- is now stored in AVBufferRef
1500 * reference, type, buffer_hints -- are unnecessary in the new API
1501 * hwaccel_picture_private, owner, thread_opaque -- should not
1502 have been accessed from outside of lavc
1503 * qscale_table, qstride, qscale_type, mbskip_table, motion_val,

1662 For audio formats with fixed frame size, the last frame
1663 no longer needs to be padded with silence, libavcodec
1664 will handle this internally (effectively all encoders
1665 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2813 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2814 Change the signature of avfilter_register() to make it return an
2815 int. This is required since now the registration operation may fail.
2817 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2818 Make the pixdesc.h API public.

2842 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2843 Add a pts field to AVSubtitle which gives the subtitle packet pts
2844 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

2847 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2848 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2849 major version. Use AV_PKT_FLAG_KEY instead.
2851 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2852 av_lockmgr_register() can be used to register a callback function
2853 that lavc (and in the future, libraries that depend on lavc) can use
2854 to implement mutexes. The application should provide a callback function
2855 that implements the AV_LOCK_* operations described in avcodec.h.
2856 When the lock manager is registered, FFmpeg is guaranteed to behave
2857 correctly in a multi-threaded application.
2859 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2860 av_free_packet() is no longer an inline function. It is now exported.
2862 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2863 Please use NULL instead. This has been supported since r16506
2864 (lavf > 52.23.1, lavc > 52.10.0).
2866 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2867 The old decoding functions are deprecated, all new code should use the
2868 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2869 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2870 argument instead of a const uint8_t *buf / int buf_size pair.
2872 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2873 Introduce the av_fifo_space() function.
2875 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2876 Move AVPacket declaration from libavformat/avformat.h to
2877 libavcodec/avcodec.h.
2879 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2880 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2881 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2882 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2883 PIX_FMT_BGR32_1 are now macros.
2884 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2885 Re-sort the enum PixelFormat list accordingly.
2886 This change breaks API/ABI backward compatibility.
2888 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2889 Add the enum PixelFormat values:
2890 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2891 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2893 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2894 The Mersenne Twister PRNG implemented through the av_random* functions
2895 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2898 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2899 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2900 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2901 and av_fifo_realloc2.
2902 In addition, the order of the function arguments of av_fifo_generic_read
2903 was changed to match av_fifo_generic_write.
2904 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2905 applications, they may not use sizeof() or directly access members.
2907 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2908 Introduce a new metadata API (see av_metadata_get() and friends).
2909 The old API is now deprecated and should not be used anymore. This especially
2910 includes the following structure fields:
2911 - AVFormatContext.title
2912 - AVFormatContext.author
2913 - AVFormatContext.copyright
2914 - AVFormatContext.comment
2915 - AVFormatContext.album
2916 - AVFormatContext.year
2917 - AVFormatContext.track
2918 - AVFormatContext.genre
2921 - AVProgram.provider_name
