129 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
130 (via an entry named "rotate"). Use av_stream_get_side_data() with
131 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with

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

239 Decoders now export the frame timestamp as AVFrame.pts. It was
240 previously exported as AVFrame.pkt_pts, which is now deprecated.
242 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
243 and not the codec timebase.

284 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
285 Moved codecpar field from AVStream to the end of the struct, so that
286 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
288 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
289 Moved hw_frames_ctx field from AVFrame to the end of the struct, so that

292 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
293 Fix accidental ABI breakage in AVFilterContext.
294 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
296 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
297 compatible with lavfi>=6.47.100. Potentially also affects other users of
298 libavfilter if they are using one of the affected fields.

350 2016-03-11 - 6d8ab35 - lavf/lavc 57.28.101
351 Add requirement to bitstream filtering API that returned packets with
352 size == 0 and side_data_elems == 0 are to be skipped by the caller.
354 2016-03-04 - 9362973 - lavf 57.28.100
355 Add protocol blacklisting API
357 2016-02-28 - 4dd4d53 - lavc 57.27.101
358 Validate AVFrame returned by get_buffer2 to have required
359 planes not NULL and unused planes set to NULL as crashes
360 and buffer overflow are possible with certain streams if
361 that is not the case.
363 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
364 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
365 the reset of the ASS ReadOrder field on flush. This affects the content of
366 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
369 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
370 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
371 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
372 The default value for this option will change to "ass" at the next major
373 libavcodec version bump.
375 The current default is "ass_with_timings" for compatibility. This means that
376 all subtitles text decoders currently still output ASS with timings printed
377 as strings in the AVSubtitles.rects[N]->ass fields.
379 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
380 timing is limited to a 1/100 time base, so this is relevant for any subtitles
381 format needing a bigger one), ease timing adjustments, and prevents the need
382 of removing the timing from the decoded string yourself. This form is also

2823 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2824 PKT_FLAG_KEY has been deprecated and will be dropped at the next

2827 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2828 av_lockmgr_register() can be used to register a callback function
2829 that lavc (and in the future, libraries that depend on lavc) can use
2830 to implement mutexes. The application should provide a callback function
2831 that implements the AV_LOCK_* operations described in avcodec.h.
2832 When the lock manager is registered, FFmpeg is guaranteed to behave
2833 correctly in a multi-threaded application.
2835 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2836 av_free_packet() is no longer an inline function. It is now exported.
2838 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2839 Please use NULL instead. This has been supported since r16506
2840 (lavf > 52.23.1, lavc > 52.10.0).
2842 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2843 The old decoding functions are deprecated, all new code should use the
2844 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2845 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2846 argument instead of a const uint8_t *buf / int buf_size pair.
2848 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2849 Introduce the av_fifo_space() function.

2852 Move AVPacket declaration from libavformat/avformat.h to
2853 libavcodec/avcodec.h.
2855 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2856 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2857 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2858 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2859 PIX_FMT_BGR32_1 are now macros.
2860 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2861 Re-sort the enum PixelFormat list accordingly.
2862 This change breaks API/ABI backward compatibility.
2864 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2865 Add the enum PixelFormat values:
2866 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2867 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2869 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2870 The Mersenne Twister PRNG implemented through the av_random* functions
2871 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2874 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2875 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2876 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2877 and av_fifo_realloc2.
2878 In addition, the order of the function arguments of av_fifo_generic_read
2879 was changed to match av_fifo_generic_write.
2880 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2881 applications, they may not use sizeof() or directly access members.
2883 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2884 Introduce a new metadata API (see av_metadata_get() and friends).
2885 The old API is now deprecated and should not be used anymore. This especially
2886 includes the following structure fields:
2887 - AVFormatContext.title
2888 - AVFormatContext.author
2889 - AVFormatContext.copyright
2890 - AVFormatContext.comment
2891 - AVFormatContext.album
2892 - AVFormatContext.year
2893 - AVFormatContext.track
2894 - AVFormatContext.genre
2897 - AVProgram.provider_name
