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

119 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
120 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
121 set the Cuda device handle.
123 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h
124 Add av_strireplace().

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

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

178 2017-03-18 - 3796fb2692 - lavfi 6.77.100 - avfilter.h
179 Deprecate AVFilterGraph.resample_lavr_opts

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

193 in AVFrame, AVCodecContext, and AVFormatContext that were previously

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

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

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

1488 reget_buffer(), avcodec_default_get_buffer(),
1489 avcodec_default_reget_buffer(), avcodec_default_release_buffer().
1490 Remove avcodec_default_free_buffers(), which should not have ever
1491 been called from outside of lavc.
1492 Deprecate the following AVFrame fields:
1493 * base -- is now stored in AVBufferRef
1494 * reference, type, buffer_hints -- are unnecessary in the new API
1495 * hwaccel_picture_private, owner, thread_opaque -- should not
1496 have been accessed from outside of lavc
1497 * qscale_table, qstride, qscale_type, mbskip_table, motion_val,
1498 mb_type, dct_coeff, ref_index -- mpegvideo-specific tables,
1499 which are not exported anymore.

1656 For audio formats with fixed frame size, the last frame
1657 no longer needs to be padded with silence, libavcodec
1658 will handle this internally (effectively all encoders
1659 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2807 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2808 Change the signature of avfilter_register() to make it return an
2809 int. This is required since now the registration operation may fail.
2811 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2812 Make the pixdesc.h API public.

2836 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2837 Add a pts field to AVSubtitle which gives the subtitle packet pts
2838 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

2841 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2842 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2843 major version. Use AV_PKT_FLAG_KEY instead.
2845 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2846 av_lockmgr_register() can be used to register a callback function
2847 that lavc (and in the future, libraries that depend on lavc) can use
2848 to implement mutexes. The application should provide a callback function
2849 that implements the AV_LOCK_* operations described in avcodec.h.
2850 When the lock manager is registered, FFmpeg is guaranteed to behave
2851 correctly in a multi-threaded application.
2853 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2854 av_free_packet() is no longer an inline function. It is now exported.
2856 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2857 Please use NULL instead. This has been supported since r16506
2858 (lavf > 52.23.1, lavc > 52.10.0).
2860 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2861 The old decoding functions are deprecated, all new code should use the
2862 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2863 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2864 argument instead of a const uint8_t *buf / int buf_size pair.
2866 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2867 Introduce the av_fifo_space() function.
2869 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2870 Move AVPacket declaration from libavformat/avformat.h to
2871 libavcodec/avcodec.h.
2873 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2874 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2875 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2876 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2877 PIX_FMT_BGR32_1 are now macros.
2878 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2879 Re-sort the enum PixelFormat list accordingly.
2880 This change breaks API/ABI backward compatibility.
2882 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2883 Add the enum PixelFormat values:
2884 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2885 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2887 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2888 The Mersenne Twister PRNG implemented through the av_random* functions
2889 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2892 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2893 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2894 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2895 and av_fifo_realloc2.
2896 In addition, the order of the function arguments of av_fifo_generic_read
2897 was changed to match av_fifo_generic_write.
2898 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2899 applications, they may not use sizeof() or directly access members.
2901 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2902 Introduce a new metadata API (see av_metadata_get() and friends).
2903 The old API is now deprecated and should not be used anymore. This especially
2904 includes the following structure fields:
2905 - AVFormatContext.title
2906 - AVFormatContext.author
2907 - AVFormatContext.copyright
2908 - AVFormatContext.comment
2909 - AVFormatContext.album
2910 - AVFormatContext.year
2911 - AVFormatContext.track
2912 - AVFormatContext.genre
2915 - AVProgram.provider_name
