106 2017-05-05 - xxxxxxxxxx - lavc 57.94.100 - avcodec.h
107 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
108 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
109 set the Cuda device handle.
111 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h
112 Add av_strireplace().
114 2016-04-06 - 157e57a181 - lavc 57.92.100 - avcodec.h

135 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
136 (via an entry named "rotate"). Use av_stream_get_side_data() with
137 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
138 av_display_rotation_get(). The same is done for muxing. Instead of adding a
139 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
140 to be added to the AVStream.

155 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
156 bump, and libavformat will behave as if it were always set.
157 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().
159 2016-03-20 - 8200b16a9c - lavu 55.50.100 / 55.21.0 - imgutils.h
160 Add av_image_copy_uc_from(), a version of av_image_copy() for copying
161 from GPU mapped memory.
163 2017-03-20 - 9c2436e - lavu 55.49.100 - pixdesc.h
164 Add AV_PIX_FMT_FLAG_BAYER pixel format flag.
166 2017-03-18 - 3796fb2692 - lavfi 6.77.100 - avfilter.h
167 Deprecate AVFilterGraph.resample_lavr_opts
168 It's never been used by avfilter nor passed to anything.

175 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
176 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
177 native decoder format. (The default value is not changed.)
179 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
180 Remove requirement to use AVOption or accessors to access certain fields
181 in AVFrame, AVCodecContext, and AVFormatContext that were previously
182 documented as "no direct access" allowed.
184 2017-02-13 - c1a5fca06f - lavc 57.80.100 - avcodec.h

199 2017-01-17 - 2a4a8653b6 - lavc 57.74.100 - vaapi.h
200 Deprecate struct vaapi_context and the vaapi.h installed header.
201 Callers should set AVCodecContext.hw_frames_ctx instead.
203 2017-01-12 - dbe9dbed31 - lavfi 6.69.100 - buffersink.h
204 Add av_buffersink_get_*() functions.

245 Decoders now export the frame timestamp as AVFrame.pts. It was
246 previously exported as AVFrame.pkt_pts, which is now deprecated.
248 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
249 and not the codec timebase.

291 Moved codecpar field from AVStream to the end of the struct, so that
292 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
294 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h

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

358 size == 0 and side_data_elems == 0 are to be skipped by the caller.
360 2016-03-04 - 9362973 - lavf 57.28.100
361 Add protocol blacklisting API

364 Validate AVFrame returned by get_buffer2 to have required
365 planes not NULL and unused planes set to NULL as crashes
366 and buffer overflow are possible with certain streams if
367 that is not the case.

370 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
371 the reset of the ASS ReadOrder field on flush. This affects the content of
372 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
375 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
376 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
377 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
378 The default value for this option will change to "ass" at the next major
379 libavcodec version bump.
381 The current default is "ass_with_timings" for compatibility. This means that
382 all subtitles text decoders currently still output ASS with timings printed
383 as strings in the AVSubtitles.rects[N]->ass fields.
385 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
386 timing is limited to a 1/100 time base, so this is relevant for any subtitles
387 format needing a bigger one), ease timing adjustments, and prevents the need
388 of removing the timing from the decoded string yourself. This form is also
389 known as "the Matroska form". The timing information (start time, duration)
390 can be found in the AVSubtitles fields.

2795 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2796 Change the signature of avfilter_register() to make it return an
2797 int. This is required since now the registration operation may fail.
2799 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2800 Make the pixdesc.h API public.

2824 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2825 Add a pts field to AVSubtitle which gives the subtitle packet pts
2826 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

2829 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2830 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2831 major version. Use AV_PKT_FLAG_KEY instead.
2833 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2834 av_lockmgr_register() can be used to register a callback function
2835 that lavc (and in the future, libraries that depend on lavc) can use
2836 to implement mutexes. The application should provide a callback function
2837 that implements the AV_LOCK_* operations described in avcodec.h.
2838 When the lock manager is registered, FFmpeg is guaranteed to behave
2839 correctly in a multi-threaded application.
2841 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2842 av_free_packet() is no longer an inline function. It is now exported.
2844 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2845 Please use NULL instead. This has been supported since r16506
2846 (lavf > 52.23.1, lavc > 52.10.0).
2848 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2849 The old decoding functions are deprecated, all new code should use the
2850 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2851 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2852 argument instead of a const uint8_t *buf / int buf_size pair.
2854 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2855 Introduce the av_fifo_space() function.
2857 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2858 Move AVPacket declaration from libavformat/avformat.h to
2859 libavcodec/avcodec.h.
2861 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2862 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2863 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2864 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2865 PIX_FMT_BGR32_1 are now macros.
2866 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2867 Re-sort the enum PixelFormat list accordingly.
2868 This change breaks API/ABI backward compatibility.
2870 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2871 Add the enum PixelFormat values:
2872 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2873 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2875 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2876 The Mersenne Twister PRNG implemented through the av_random* functions
2877 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2880 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2881 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2882 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2883 and av_fifo_realloc2.
2884 In addition, the order of the function arguments of av_fifo_generic_read
2885 was changed to match av_fifo_generic_write.
2886 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2887 applications, they may not use sizeof() or directly access members.
2889 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2890 Introduce a new metadata API (see av_metadata_get() and friends).
2891 The old API is now deprecated and should not be used anymore. This especially
2892 includes the following structure fields:
2893 - AVFormatContext.title
2894 - AVFormatContext.author
2895 - AVFormatContext.copyright
2896 - AVFormatContext.comment
2897 - AVFormatContext.album
2898 - AVFormatContext.year
2899 - AVFormatContext.track
2900 - AVFormatContext.genre
2903 - AVProgram.provider_name
