62 parameter type to size_t at next major bump.
64 2017-05-05 - xxxxxxxxxx - lavc 57.94.100 - avcodec.h
65 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
66 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
67 set the Cuda device handle.
69 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

92 2017-03-27 - ddef3d902f - lavf 57.68.100 - avformat.h
93 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
94 (via an entry named "rotate"). Use av_stream_get_side_data() with
95 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
96 av_display_rotation_get(). The same is done for muxing. Instead of adding a
97 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
98 to be added to the AVStream.

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

119 from GPU mapped memory.
121 2017-03-20 - 9c2436e - lavu 55.49.100 - pixdesc.h
122 Add AV_PIX_FMT_FLAG_BAYER pixel format flag.
124 2017-03-18 - 3796fb2692 - lavfi 6.77.100 - avfilter.h
125 Deprecate AVFilterGraph.resample_lavr_opts
126 It's never been used by avfilter nor passed to anything.

129 Add AV_SPHERICAL_EQUIRECTANGULAR_TILE, av_spherical_tile_bounds(),
130 and projection-specific properties (bound_left, bound_top, bound_right,
131 bound_bottom, padding) to AVSphericalMapping.
133 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
134 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
135 native decoder format. (The default value is not changed.)
137 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
138 Remove requirement to use AVOption or accessors to access certain fields
139 in AVFrame, AVCodecContext, and AVFormatContext that were previously
140 documented as "no direct access" allowed.
142 2017-02-13 - c1a5fca06f - lavc 57.80.100 - avcodec.h
143 Add AVCodecContext.hw_device_ctx.

158 Deprecate struct vaapi_context and the vaapi.h installed header.
159 Callers should set AVCodecContext.hw_frames_ctx instead.
161 2017-01-12 - dbe9dbed31 - lavfi 6.69.100 - buffersink.h
162 Add av_buffersink_get_*() functions.

203 Decoders now export the frame timestamp as AVFrame.pts. It was
204 previously exported as AVFrame.pkt_pts, which is now deprecated.
206 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
207 and not the codec timebase.

249 Moved codecpar field from AVStream to the end of the struct, so that
250 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
252 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
253 Moved hw_frames_ctx field from AVFrame to the end of the struct, so that
254 the following private fields are in the same location as in FFmpeg 3.0 (lavu 55.17.103).
256 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
257 Fix accidental ABI breakage in AVFilterContext.
258 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
260 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
261 compatible with lavfi>=6.47.100. Potentially also affects other users of
262 libavfilter if they are using one of the affected fields.

315 Add requirement to bitstream filtering API that returned packets with
316 size == 0 and side_data_elems == 0 are to be skipped by the caller.
318 2016-03-04 - 9362973 - lavf 57.28.100
319 Add protocol blacklisting API

322 Validate AVFrame returned by get_buffer2 to have required
323 planes not NULL and unused planes set to NULL as crashes
324 and buffer overflow are possible with certain streams if
325 that is not the case.
327 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
328 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
329 the reset of the ASS ReadOrder field on flush. This affects the content of
330 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
333 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
334 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
335 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
336 The default value for this option will change to "ass" at the next major
337 libavcodec version bump.
339 The current default is "ass_with_timings" for compatibility. This means that
340 all subtitles text decoders currently still output ASS with timings printed
341 as strings in the AVSubtitles.rects[N]->ass fields.
343 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
344 timing is limited to a 1/100 time base, so this is relevant for any subtitles
345 format needing a bigger one), ease timing adjustments, and prevents the need
346 of removing the timing from the decoded string yourself. This form is also
347 known as "the Matroska form". The timing information (start time, duration)
348 can be found in the AVSubtitles fields.

2753 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2754 Change the signature of avfilter_register() to make it return an
2755 int. This is required since now the registration operation may fail.
2757 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2758 Make the pixdesc.h API public.

2782 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2783 Add a pts field to AVSubtitle which gives the subtitle packet pts
2784 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

2787 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2788 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2789 major version. Use AV_PKT_FLAG_KEY instead.
2791 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2792 av_lockmgr_register() can be used to register a callback function
2793 that lavc (and in the future, libraries that depend on lavc) can use
2794 to implement mutexes. The application should provide a callback function
2795 that implements the AV_LOCK_* operations described in avcodec.h.
2796 When the lock manager is registered, FFmpeg is guaranteed to behave
2797 correctly in a multi-threaded application.
2799 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2800 av_free_packet() is no longer an inline function. It is now exported.
2802 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2803 Please use NULL instead. This has been supported since r16506
2804 (lavf > 52.23.1, lavc > 52.10.0).
2806 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2807 The old decoding functions are deprecated, all new code should use the
2808 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2809 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2810 argument instead of a const uint8_t *buf / int buf_size pair.
2812 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2813 Introduce the av_fifo_space() function.
2815 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2816 Move AVPacket declaration from libavformat/avformat.h to
2817 libavcodec/avcodec.h.
2819 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2820 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2821 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2822 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2823 PIX_FMT_BGR32_1 are now macros.
2824 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2825 Re-sort the enum PixelFormat list accordingly.
2826 This change breaks API/ABI backward compatibility.
2828 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2829 Add the enum PixelFormat values:
2830 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2831 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2833 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2834 The Mersenne Twister PRNG implemented through the av_random* functions
2835 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2838 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2839 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2840 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2841 and av_fifo_realloc2.
2842 In addition, the order of the function arguments of av_fifo_generic_read
2843 was changed to match av_fifo_generic_write.
2844 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2845 applications, they may not use sizeof() or directly access members.
2847 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2848 Introduce a new metadata API (see av_metadata_get() and friends).
2849 The old API is now deprecated and should not be used anymore. This especially
2850 includes the following structure fields:
2851 - AVFormatContext.title
2852 - AVFormatContext.author
2853 - AVFormatContext.copyright
2854 - AVFormatContext.comment
2855 - AVFormatContext.album
2856 - AVFormatContext.year
2857 - AVFormatContext.track
2858 - AVFormatContext.genre
2861 - AVProgram.provider_name
