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

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

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

3002 Add a type field to AVFilterLink.
3004 Change the field types:
3005 enum PixelFormat format -> int format in AVFilterBuffer
3006 enum PixelFormat *formats -> int *formats in AVFilterFormats
3007 enum PixelFormat *format -> int format in AVFilterLink
3009 Change the function signatures:
3010 AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
3011 AVFilterFormats *avfilter_make_format_list(const int *fmts);
3013 int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
3014 int avfilter_add_format (AVFilterFormats **avff, int fmt);
3016 AVFilterFormats *avfilter_all_colorspaces(void); ->
3017 AVFilterFormats *avfilter_all_formats (enum AVMediaType type);
3019 This change breaks libavfilter API/ABI.

3207 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3208 Introduce the avfilter_next() function.
3210 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3211 Change the signature of avfilter_register() to make it return an
3212 int. This is required since now the registration operation may fail.
3214 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3215 Make the pixdesc.h API public.
3217 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3234 Add w and h fields to AVFilterPic.
3236 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3237 This is now an unsigned int instead of a signed int.
3239 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3240 Add a pts field to AVSubtitle which gives the subtitle packet pts
3241 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3242 not work right without this.
3244 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3245 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3246 major version. Use AV_PKT_FLAG_KEY instead.
3248 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3249 av_lockmgr_register() can be used to register a callback function
3250 that lavc (and in the future, libraries that depend on lavc) can use
3251 to implement mutexes. The application should provide a callback function
3252 that implements the AV_LOCK_* operations described in avcodec.h.
3253 When the lock manager is registered, FFmpeg is guaranteed to behave
3254 correctly in a multi-threaded application.
3256 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3257 av_free_packet() is no longer an inline function. It is now exported.
3259 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3260 Please use NULL instead. This has been supported since r16506
3261 (lavf > 52.23.1, lavc > 52.10.0).
3263 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3264 The old decoding functions are deprecated, all new code should use the
3265 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3266 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3267 argument instead of a const uint8_t *buf / int buf_size pair.
3269 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3270 Introduce the av_fifo_space() function.
3272 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3273 Move AVPacket declaration from libavformat/avformat.h to
3274 libavcodec/avcodec.h.
3276 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3277 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3278 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3279 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3280 PIX_FMT_BGR32_1 are now macros.
3281 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3282 Re-sort the enum PixelFormat list accordingly.
3283 This change breaks API/ABI backward compatibility.
3285 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3286 Add the enum PixelFormat values:
3287 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3288 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3290 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3291 The Mersenne Twister PRNG implemented through the av_random* functions
3292 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3295 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3296 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3297 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3298 and av_fifo_realloc2.
3299 In addition, the order of the function arguments of av_fifo_generic_read
3300 was changed to match av_fifo_generic_write.
3301 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3302 applications, they may not use sizeof() or directly access members.
3304 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3305 Introduce a new metadata API (see av_metadata_get() and friends).
3306 The old API is now deprecated and should not be used anymore. This especially
3307 includes the following structure fields:
3308 - AVFormatContext.title
3309 - AVFormatContext.author
3310 - AVFormatContext.copyright
3311 - AVFormatContext.comment
3312 - AVFormatContext.album
3313 - AVFormatContext.year
3314 - AVFormatContext.track
3315 - AVFormatContext.genre
3318 - AVProgram.provider_name
