479 (via an entry named "rotate"). Use av_stream_get_side_data() with
480 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
481 av_display_rotation_get(). The same is done for muxing. Instead of adding a
482 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
483 to be added to the AVStream.

588 Decoders now export the frame timestamp as AVFrame.pts. It was
589 previously exported as AVFrame.pkt_pts, which is now deprecated.
591 Note: When decoding, AVFrame.pts uses the stream/packet timebase,

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

713 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing

718 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
719 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
720 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
721 The default value for this option will change to "ass" at the next major
722 libavcodec version bump.
724 The current default is "ass_with_timings" for compatibility. This means that
725 all subtitles text decoders currently still output ASS with timings printed
726 as strings in the AVSubtitles.rects[N]->ass fields.
728 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
729 timing is limited to a 1/100 time base, so this is relevant for any subtitles
730 format needing a bigger one), ease timing adjustments, and prevents the need
731 of removing the timing from the decoded string yourself. This form is also
732 known as "the Matroska form". The timing information (start time, duration)
733 can be found in the AVSubtitles fields.

3135 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3136 Introduce the avfilter_next() function.
3138 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3139 Change the signature of avfilter_register() to make it return an
3140 int. This is required since now the registration operation may fail.
3142 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3143 Make the pixdesc.h API public.

3167 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3168 Add a pts field to AVSubtitle which gives the subtitle packet pts
3169 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3170 not work right without this.
3172 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3173 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3174 major version. Use AV_PKT_FLAG_KEY instead.
3176 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3177 av_lockmgr_register() can be used to register a callback function
3178 that lavc (and in the future, libraries that depend on lavc) can use
3179 to implement mutexes. The application should provide a callback function
3180 that implements the AV_LOCK_* operations described in avcodec.h.
3181 When the lock manager is registered, FFmpeg is guaranteed to behave
3182 correctly in a multi-threaded application.
3184 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3185 av_free_packet() is no longer an inline function. It is now exported.
3187 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3188 Please use NULL instead. This has been supported since r16506
3189 (lavf > 52.23.1, lavc > 52.10.0).
3191 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3192 The old decoding functions are deprecated, all new code should use the
3193 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3194 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3195 argument instead of a const uint8_t *buf / int buf_size pair.
3197 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3198 Introduce the av_fifo_space() function.
3200 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3201 Move AVPacket declaration from libavformat/avformat.h to
3202 libavcodec/avcodec.h.
3204 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3205 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3206 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3207 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3208 PIX_FMT_BGR32_1 are now macros.
3209 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3210 Re-sort the enum PixelFormat list accordingly.
3211 This change breaks API/ABI backward compatibility.
3213 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3214 Add the enum PixelFormat values:
3215 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3216 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3218 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3219 The Mersenne Twister PRNG implemented through the av_random* functions
3220 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3223 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3224 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3225 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3226 and av_fifo_realloc2.
3227 In addition, the order of the function arguments of av_fifo_generic_read
3228 was changed to match av_fifo_generic_write.
3229 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3230 applications, they may not use sizeof() or directly access members.
3232 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3233 Introduce a new metadata API (see av_metadata_get() and friends).
3234 The old API is now deprecated and should not be used anymore. This especially
3235 includes the following structure fields:
3236 - AVFormatContext.title
3237 - AVFormatContext.author
3238 - AVFormatContext.copyright
3239 - AVFormatContext.comment
3240 - AVFormatContext.album
3241 - AVFormatContext.year
3242 - AVFormatContext.track
3243 - AVFormatContext.genre
3246 - AVProgram.provider_name
