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

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

782 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
783 the reset of the ASS ReadOrder field on flush. This affects the content of
784 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
787 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
788 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
789 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
790 The default value for this option will change to "ass" at the next major
791 libavcodec version bump.
793 The current default is "ass_with_timings" for compatibility. This means that
794 all subtitles text decoders currently still output ASS with timings printed
795 as strings in the AVSubtitles.rects[N]->ass fields.
797 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
798 timing is limited to a 1/100 time base, so this is relevant for any subtitles
799 format needing a bigger one), ease timing adjustments, and prevents the need
800 of removing the timing from the decoded string yourself. This form is also
801 known as "the Matroska form". The timing information (start time, duration)
802 can be found in the AVSubtitles fields.

3001 Change the field types:
3002 enum PixelFormat format -> int format in AVFilterBuffer
3003 enum PixelFormat *formats -> int *formats in AVFilterFormats
3004 enum PixelFormat *format -> int format in AVFilterLink
3006 Change the function signatures:
3007 AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
3008 AVFilterFormats *avfilter_make_format_list(const int *fmts);
3010 int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
3011 int avfilter_add_format (AVFilterFormats **avff, int fmt);
3013 AVFilterFormats *avfilter_all_colorspaces(void); ->
3014 AVFilterFormats *avfilter_all_formats (enum AVMediaType type);
3016 This change breaks libavfilter API/ABI.

3204 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3205 Introduce the avfilter_next() function.
3207 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3208 Change the signature of avfilter_register() to make it return an
3209 int. This is required since now the registration operation may fail.
3211 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3212 Make the pixdesc.h API public.
3214 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3231 Add w and h fields to AVFilterPic.
3233 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3234 This is now an unsigned int instead of a signed int.
3236 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3237 Add a pts field to AVSubtitle which gives the subtitle packet pts
3238 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3239 not work right without this.
3241 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3242 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3243 major version. Use AV_PKT_FLAG_KEY instead.
3245 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3246 av_lockmgr_register() can be used to register a callback function
3247 that lavc (and in the future, libraries that depend on lavc) can use
3248 to implement mutexes. The application should provide a callback function
3249 that implements the AV_LOCK_* operations described in avcodec.h.
3250 When the lock manager is registered, FFmpeg is guaranteed to behave
3251 correctly in a multi-threaded application.
3253 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3254 av_free_packet() is no longer an inline function. It is now exported.
3256 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3257 Please use NULL instead. This has been supported since r16506
3258 (lavf > 52.23.1, lavc > 52.10.0).
3260 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3261 The old decoding functions are deprecated, all new code should use the
3262 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3263 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3264 argument instead of a const uint8_t *buf / int buf_size pair.
3266 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3267 Introduce the av_fifo_space() function.
3269 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3270 Move AVPacket declaration from libavformat/avformat.h to
3271 libavcodec/avcodec.h.
3273 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3274 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3275 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3276 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3277 PIX_FMT_BGR32_1 are now macros.
3278 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3279 Re-sort the enum PixelFormat list accordingly.
3280 This change breaks API/ABI backward compatibility.
3282 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3283 Add the enum PixelFormat values:
3284 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3285 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3287 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3288 The Mersenne Twister PRNG implemented through the av_random* functions
3289 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3292 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3293 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3294 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3295 and av_fifo_realloc2.
3296 In addition, the order of the function arguments of av_fifo_generic_read
3297 was changed to match av_fifo_generic_write.
3298 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3299 applications, they may not use sizeof() or directly access members.
3301 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3302 Introduce a new metadata API (see av_metadata_get() and friends).
3303 The old API is now deprecated and should not be used anymore. This especially
3304 includes the following structure fields:
3305 - AVFormatContext.title
3306 - AVFormatContext.author
3307 - AVFormatContext.copyright
3308 - AVFormatContext.comment
3309 - AVFormatContext.album
3310 - AVFormatContext.year
3311 - AVFormatContext.track
3312 - AVFormatContext.genre
3315 - AVProgram.provider_name
