579 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
580 (via an entry named "rotate"). Use av_stream_get_side_data() with
581 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
582 av_display_rotation_get(). The same is done for muxing. Instead of adding a
583 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has

689 Decoders now export the frame timestamp as AVFrame.pts. It was
690 previously exported as AVFrame.pkt_pts, which is now deprecated.

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

813 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
814 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
815 the reset of the ASS ReadOrder field on flush. This affects the content of
816 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
819 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
820 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
821 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
822 The default value for this option will change to "ass" at the next major
823 libavcodec version bump.
825 The current default is "ass_with_timings" for compatibility. This means that
826 all subtitles text decoders currently still output ASS with timings printed
827 as strings in the AVSubtitles.rects[N]->ass fields.
829 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
830 timing is limited to a 1/100 time base, so this is relevant for any subtitles
831 format needing a bigger one), ease timing adjustments, and prevents the need
832 of removing the timing from the decoded string yourself. This form is also
833 known as "the Matroska form". The timing information (start time, duration)
834 can be found in the AVSubtitles fields.

3236 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3237 Introduce the avfilter_next() function.
3239 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3240 Change the signature of avfilter_register() to make it return an
3241 int. This is required since now the registration operation may fail.
3243 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3244 Make the pixdesc.h API public.
3246 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3263 Add w and h fields to AVFilterPic.
3265 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3266 This is now an unsigned int instead of a signed int.
3268 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3269 Add a pts field to AVSubtitle which gives the subtitle packet pts
3270 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3271 not work right without this.
3273 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3274 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3275 major version. Use AV_PKT_FLAG_KEY instead.
3277 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3278 av_lockmgr_register() can be used to register a callback function
3279 that lavc (and in the future, libraries that depend on lavc) can use
3280 to implement mutexes. The application should provide a callback function
3281 that implements the AV_LOCK_* operations described in avcodec.h.
3282 When the lock manager is registered, FFmpeg is guaranteed to behave
3283 correctly in a multi-threaded application.
3285 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3286 av_free_packet() is no longer an inline function. It is now exported.
3288 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3289 Please use NULL instead. This has been supported since r16506
3290 (lavf > 52.23.1, lavc > 52.10.0).
3292 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3293 The old decoding functions are deprecated, all new code should use the
3294 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3295 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3296 argument instead of a const uint8_t *buf / int buf_size pair.
3298 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3299 Introduce the av_fifo_space() function.
3301 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3302 Move AVPacket declaration from libavformat/avformat.h to
3303 libavcodec/avcodec.h.
3305 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3306 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3307 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3308 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3309 PIX_FMT_BGR32_1 are now macros.
3310 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3311 Re-sort the enum PixelFormat list accordingly.
3312 This change breaks API/ABI backward compatibility.
3314 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3315 Add the enum PixelFormat values:
3316 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3317 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3319 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3320 The Mersenne Twister PRNG implemented through the av_random* functions
3321 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3324 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3325 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3326 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3327 and av_fifo_realloc2.
3328 In addition, the order of the function arguments of av_fifo_generic_read
3329 was changed to match av_fifo_generic_write.
3330 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3331 applications, they may not use sizeof() or directly access members.
3333 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3334 Introduce a new metadata API (see av_metadata_get() and friends).
3335 The old API is now deprecated and should not be used anymore. This especially
3336 includes the following structure fields:
3337 - AVFormatContext.title
3338 - AVFormatContext.author
3339 - AVFormatContext.copyright
3340 - AVFormatContext.comment
3341 - AVFormatContext.album
3342 - AVFormatContext.year
3343 - AVFormatContext.track
3344 - AVFormatContext.genre
3347 - AVProgram.provider_name
