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

806 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
807 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
808 the reset of the ASS ReadOrder field on flush. This affects the content of
809 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
812 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
813 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
814 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
815 The default value for this option will change to "ass" at the next major
816 libavcodec version bump.
818 The current default is "ass_with_timings" for compatibility. This means that
819 all subtitles text decoders currently still output ASS with timings printed
820 as strings in the AVSubtitles.rects[N]->ass fields.
822 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
823 timing is limited to a 1/100 time base, so this is relevant for any subtitles
824 format needing a bigger one), ease timing adjustments, and prevents the need
825 of removing the timing from the decoded string yourself. This form is also
826 known as "the Matroska form". The timing information (start time, duration)
827 can be found in the AVSubtitles fields.

3227 Remove the next field from AVFilter, this is not anymore required.
3229 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3230 Introduce the avfilter_next() function.
3232 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3233 Change the signature of avfilter_register() to make it return an
3234 int. This is required since now the registration operation may fail.
3236 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3237 Make the pixdesc.h API public.
3239 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3244 Add a description field to AVFilter.
3246 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()

3256 Add w and h fields to AVFilterPic.
3258 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3259 This is now an unsigned int instead of a signed int.
3261 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3262 Add a pts field to AVSubtitle which gives the subtitle packet pts
3263 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3264 not work right without this.
3266 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3267 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3268 major version. Use AV_PKT_FLAG_KEY instead.
3270 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3271 av_lockmgr_register() can be used to register a callback function
3272 that lavc (and in the future, libraries that depend on lavc) can use
3273 to implement mutexes. The application should provide a callback function
3274 that implements the AV_LOCK_* operations described in avcodec.h.
3275 When the lock manager is registered, FFmpeg is guaranteed to behave
3276 correctly in a multi-threaded application.
3278 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3279 av_free_packet() is no longer an inline function. It is now exported.
3281 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3282 Please use NULL instead. This has been supported since r16506
3283 (lavf > 52.23.1, lavc > 52.10.0).
3285 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3286 The old decoding functions are deprecated, all new code should use the
3287 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3288 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3289 argument instead of a const uint8_t *buf / int buf_size pair.
3291 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3292 Introduce the av_fifo_space() function.
3294 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3295 Move AVPacket declaration from libavformat/avformat.h to
3296 libavcodec/avcodec.h.
3298 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3299 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3300 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3301 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3302 PIX_FMT_BGR32_1 are now macros.
3303 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3304 Re-sort the enum PixelFormat list accordingly.
3305 This change breaks API/ABI backward compatibility.
3307 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3308 Add the enum PixelFormat values:
3309 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3310 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3312 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3313 The Mersenne Twister PRNG implemented through the av_random* functions
3314 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3317 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3318 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3319 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3320 and av_fifo_realloc2.
3321 In addition, the order of the function arguments of av_fifo_generic_read
3322 was changed to match av_fifo_generic_write.
3323 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3324 applications, they may not use sizeof() or directly access members.
3326 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3327 Introduce a new metadata API (see av_metadata_get() and friends).
3328 The old API is now deprecated and should not be used anymore. This especially
3329 includes the following structure fields:
3330 - AVFormatContext.title
3331 - AVFormatContext.author
3332 - AVFormatContext.copyright
3333 - AVFormatContext.comment
3334 - AVFormatContext.album
3335 - AVFormatContext.year
3336 - AVFormatContext.track
3337 - AVFormatContext.genre
3340 - AVProgram.provider_name
