568 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
569 (via an entry named "rotate"). Use av_stream_get_side_data() with

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

802 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
803 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
804 the reset of the ASS ReadOrder field on flush. This affects the content of
805 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
808 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
809 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
810 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
811 The default value for this option will change to "ass" at the next major
812 libavcodec version bump.
814 The current default is "ass_with_timings" for compatibility. This means that
815 all subtitles text decoders currently still output ASS with timings printed
816 as strings in the AVSubtitles.rects[N]->ass fields.
818 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
819 timing is limited to a 1/100 time base, so this is relevant for any subtitles
820 format needing a bigger one), ease timing adjustments, and prevents the need
821 of removing the timing from the decoded string yourself. This form is also
822 known as "the Matroska form". The timing information (start time, duration)
823 can be found in the AVSubtitles fields.

3223 Remove the next field from AVFilter, this is not anymore required.
3225 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3226 Introduce the avfilter_next() function.
3228 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3229 Change the signature of avfilter_register() to make it return an
3230 int. This is required since now the registration operation may fail.
3232 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3233 Make the pixdesc.h API public.
3235 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3252 Add w and h fields to AVFilterPic.
3254 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3255 This is now an unsigned int instead of a signed int.
3257 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3258 Add a pts field to AVSubtitle which gives the subtitle packet pts
3259 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3260 not work right without this.
3262 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3263 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3264 major version. Use AV_PKT_FLAG_KEY instead.
3266 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3267 av_lockmgr_register() can be used to register a callback function
3268 that lavc (and in the future, libraries that depend on lavc) can use
3269 to implement mutexes. The application should provide a callback function
3270 that implements the AV_LOCK_* operations described in avcodec.h.
3271 When the lock manager is registered, FFmpeg is guaranteed to behave
3272 correctly in a multi-threaded application.
3274 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3275 av_free_packet() is no longer an inline function. It is now exported.
3277 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3278 Please use NULL instead. This has been supported since r16506
3279 (lavf > 52.23.1, lavc > 52.10.0).
3281 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3282 The old decoding functions are deprecated, all new code should use the
3283 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3284 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3285 argument instead of a const uint8_t *buf / int buf_size pair.
3287 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3288 Introduce the av_fifo_space() function.
3290 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3291 Move AVPacket declaration from libavformat/avformat.h to
3292 libavcodec/avcodec.h.
3294 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3295 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3296 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3297 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3298 PIX_FMT_BGR32_1 are now macros.
3299 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3300 Re-sort the enum PixelFormat list accordingly.
3301 This change breaks API/ABI backward compatibility.
3303 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3304 Add the enum PixelFormat values:
3305 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3306 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3308 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3309 The Mersenne Twister PRNG implemented through the av_random* functions
3310 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3313 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3314 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3315 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3316 and av_fifo_realloc2.
3317 In addition, the order of the function arguments of av_fifo_generic_read
3318 was changed to match av_fifo_generic_write.
3319 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3320 applications, they may not use sizeof() or directly access members.
3322 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3323 Introduce a new metadata API (see av_metadata_get() and friends).
3324 The old API is now deprecated and should not be used anymore. This especially
3325 includes the following structure fields:
3326 - AVFormatContext.title
3327 - AVFormatContext.author
3328 - AVFormatContext.copyright
3329 - AVFormatContext.comment
3330 - AVFormatContext.album
3331 - AVFormatContext.year
3332 - AVFormatContext.track
3333 - AVFormatContext.genre
3336 - AVProgram.provider_name
