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

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

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

170 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
171 bump, and libavformat will behave as if it were always set.
172 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().
174 2016-03-20 - 8200b16a9c - lavu 55.50.100 / 55.21.0 - imgutils.h

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

196 in AVFrame, AVCodecContext, and AVFormatContext that were previously

261 previously exported as AVFrame.pkt_pts, which is now deprecated.

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

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

1484 data. Add new API for working with reference-counted AVFrames.
1485 80e9e63 / 759001c - add the refcounted_frames field to AVCodecContext to make audio and
1486 video decoders return reference-counted frames. Add get_buffer2()
1487 callback to AVCodecContext which allocates reference-counted frames.
1488 Add avcodec_default_get_buffer2() as the default get_buffer2()
1490 Deprecate AVCodecContext.get_buffer() / release_buffer() /
1491 reget_buffer(), avcodec_default_get_buffer(),
1492 avcodec_default_reget_buffer(), avcodec_default_release_buffer().
1493 Remove avcodec_default_free_buffers(), which should not have ever
1494 been called from outside of lavc.
1495 Deprecate the following AVFrame fields:
1496 * base -- is now stored in AVBufferRef
1497 * reference, type, buffer_hints -- are unnecessary in the new API
1498 * hwaccel_picture_private, owner, thread_opaque -- should not
1499 have been accessed from outside of lavc
1500 * qscale_table, qstride, qscale_type, mbskip_table, motion_val,
1501 mb_type, dct_coeff, ref_index -- mpegvideo-specific tables,
1502 which are not exported anymore.

1504 av_buffersrc_add_frame(), deprecate av_buffersrc_buffer().

1506 deprecate av_buffersink_read() and av_buffersink_read_samples().
1507 Deprecate AVFilterBufferRef and all functions for working with it.

1659 For audio formats with fixed frame size, the last frame
1660 no longer needs to be padded with silence, libavcodec
1661 will handle this internally (effectively all encoders

2810 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2811 Change the signature of avfilter_register() to make it return an
2812 int. This is required since now the registration operation may fail.
2814 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2815 Make the pixdesc.h API public.

2839 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2840 Add a pts field to AVSubtitle which gives the subtitle packet pts
2841 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

2844 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2845 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2846 major version. Use AV_PKT_FLAG_KEY instead.
2848 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2849 av_lockmgr_register() can be used to register a callback function
2850 that lavc (and in the future, libraries that depend on lavc) can use
2851 to implement mutexes. The application should provide a callback function
2852 that implements the AV_LOCK_* operations described in avcodec.h.
2853 When the lock manager is registered, FFmpeg is guaranteed to behave
2854 correctly in a multi-threaded application.
2856 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2857 av_free_packet() is no longer an inline function. It is now exported.
2859 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2860 Please use NULL instead. This has been supported since r16506
2861 (lavf > 52.23.1, lavc > 52.10.0).
2863 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2864 The old decoding functions are deprecated, all new code should use the
2865 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2866 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2867 argument instead of a const uint8_t *buf / int buf_size pair.
2869 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2870 Introduce the av_fifo_space() function.
2872 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2873 Move AVPacket declaration from libavformat/avformat.h to
2874 libavcodec/avcodec.h.
2876 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2877 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2878 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2879 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2880 PIX_FMT_BGR32_1 are now macros.
2881 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2882 Re-sort the enum PixelFormat list accordingly.
2883 This change breaks API/ABI backward compatibility.
2885 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2886 Add the enum PixelFormat values:
2887 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2888 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2890 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2891 The Mersenne Twister PRNG implemented through the av_random* functions
2892 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2895 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2896 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2897 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2898 and av_fifo_realloc2.
2899 In addition, the order of the function arguments of av_fifo_generic_read
2900 was changed to match av_fifo_generic_write.
2901 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2902 applications, they may not use sizeof() or directly access members.
2904 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2905 Introduce a new metadata API (see av_metadata_get() and friends).
2906 The old API is now deprecated and should not be used anymore. This especially
2907 includes the following structure fields:
2908 - AVFormatContext.title
2909 - AVFormatContext.author
2910 - AVFormatContext.copyright
2911 - AVFormatContext.comment
2912 - AVFormatContext.album
2913 - AVFormatContext.year
2914 - AVFormatContext.track
2915 - AVFormatContext.genre
2918 - AVProgram.provider_name
