53 parameter type to size_t at next major bump.
55 2017-05-05 - xxxxxxxxxx - lavc 57.94.100 - avcodec.h
56 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes

58 set the Cuda device handle.
60 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

84 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
85 (via an entry named "rotate"). Use av_stream_get_side_data() with
86 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
87 av_display_rotation_get(). The same is done for muxing. Instead of adding a
88 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
89 to be added to the AVStream.

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

124 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
125 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
126 native decoder format. (The default value is not changed.)
128 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
129 Remove requirement to use AVOption or accessors to access certain fields
130 in AVFrame, AVCodecContext, and AVFormatContext that were previously

194 Decoders now export the frame timestamp as AVFrame.pts. It was
195 previously exported as AVFrame.pkt_pts, which is now deprecated.
197 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
198 and not the codec timebase.

239 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
240 Moved codecpar field from AVStream to the end of the struct, so that
241 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
243 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
244 Moved hw_frames_ctx field from AVFrame to the end of the struct, so that

247 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
248 Fix accidental ABI breakage in AVFilterContext.
249 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
251 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
252 compatible with lavfi>=6.47.100. Potentially also affects other users of
253 libavfilter if they are using one of the affected fields.

306 Add requirement to bitstream filtering API that returned packets with
307 size == 0 and side_data_elems == 0 are to be skipped by the caller.
309 2016-03-04 - 9362973 - lavf 57.28.100
310 Add protocol blacklisting API
312 2016-02-28 - 4dd4d53 - lavc 57.27.101
313 Validate AVFrame returned by get_buffer2 to have required
314 planes not NULL and unused planes set to NULL as crashes
315 and buffer overflow are possible with certain streams if
316 that is not the case.
318 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
319 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
320 the reset of the ASS ReadOrder field on flush. This affects the content of
321 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
324 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
325 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
326 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
327 The default value for this option will change to "ass" at the next major
328 libavcodec version bump.
330 The current default is "ass_with_timings" for compatibility. This means that
331 all subtitles text decoders currently still output ASS with timings printed
332 as strings in the AVSubtitles.rects[N]->ass fields.
334 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
335 timing is limited to a 1/100 time base, so this is relevant for any subtitles
336 format needing a bigger one), ease timing adjustments, and prevents the need
337 of removing the timing from the decoded string yourself. This form is also
338 known as "the Matroska form". The timing information (start time, duration)
339 can be found in the AVSubtitles fields.

2778 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2779 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2780 major version. Use AV_PKT_FLAG_KEY instead.
2782 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2783 av_lockmgr_register() can be used to register a callback function
2784 that lavc (and in the future, libraries that depend on lavc) can use
2785 to implement mutexes. The application should provide a callback function
2786 that implements the AV_LOCK_* operations described in avcodec.h.
2787 When the lock manager is registered, FFmpeg is guaranteed to behave
2788 correctly in a multi-threaded application.
2790 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2791 av_free_packet() is no longer an inline function. It is now exported.
2793 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2794 Please use NULL instead. This has been supported since r16506
2795 (lavf > 52.23.1, lavc > 52.10.0).
2797 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2798 The old decoding functions are deprecated, all new code should use the
2799 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2800 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2801 argument instead of a const uint8_t *buf / int buf_size pair.
2803 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2804 Introduce the av_fifo_space() function.
2806 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2807 Move AVPacket declaration from libavformat/avformat.h to
2808 libavcodec/avcodec.h.
2810 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2811 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2812 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2813 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2814 PIX_FMT_BGR32_1 are now macros.
2815 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2816 Re-sort the enum PixelFormat list accordingly.
2817 This change breaks API/ABI backward compatibility.
2819 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2820 Add the enum PixelFormat values:
2821 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2822 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2824 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2825 The Mersenne Twister PRNG implemented through the av_random* functions
2826 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2829 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2830 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2831 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2832 and av_fifo_realloc2.
2833 In addition, the order of the function arguments of av_fifo_generic_read
2834 was changed to match av_fifo_generic_write.
2835 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2836 applications, they may not use sizeof() or directly access members.
2838 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2839 Introduce a new metadata API (see av_metadata_get() and friends).
2840 The old API is now deprecated and should not be used anymore. This especially
2841 includes the following structure fields:
2842 - AVFormatContext.title
2843 - AVFormatContext.author
2844 - AVFormatContext.copyright
2845 - AVFormatContext.comment
2846 - AVFormatContext.album
2847 - AVFormatContext.year
2848 - AVFormatContext.track
2849 - AVFormatContext.genre
2852 - AVProgram.provider_name
