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

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

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

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

2997 Change the field types:
2998 enum PixelFormat format -> int format in AVFilterBuffer
2999 enum PixelFormat *formats -> int *formats in AVFilterFormats
3000 enum PixelFormat *format -> int format in AVFilterLink
3002 Change the function signatures:
3003 AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
3004 AVFilterFormats *avfilter_make_format_list(const int *fmts);
3006 int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
3007 int avfilter_add_format (AVFilterFormats **avff, int fmt);
3009 AVFilterFormats *avfilter_all_colorspaces(void); ->
3010 AVFilterFormats *avfilter_all_formats (enum AVMediaType type);
3012 This change breaks libavfilter API/ABI.

3200 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3201 Introduce the avfilter_next() function.
3203 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3204 Change the signature of avfilter_register() to make it return an
3205 int. This is required since now the registration operation may fail.
3207 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3208 Make the pixdesc.h API public.
3210 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
3211 Add a next field to AVFilter, this is used for simplifying the

3227 Add w and h fields to AVFilterPic.
3229 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3230 This is now an unsigned int instead of a signed int.
3232 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3233 Add a pts field to AVSubtitle which gives the subtitle packet pts
3234 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3235 not work right without this.
3237 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3238 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3239 major version. Use AV_PKT_FLAG_KEY instead.
3241 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3242 av_lockmgr_register() can be used to register a callback function
3243 that lavc (and in the future, libraries that depend on lavc) can use
3244 to implement mutexes. The application should provide a callback function
3245 that implements the AV_LOCK_* operations described in avcodec.h.
3246 When the lock manager is registered, FFmpeg is guaranteed to behave
3247 correctly in a multi-threaded application.
3249 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3250 av_free_packet() is no longer an inline function. It is now exported.
3252 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3253 Please use NULL instead. This has been supported since r16506
3254 (lavf > 52.23.1, lavc > 52.10.0).
3256 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3257 The old decoding functions are deprecated, all new code should use the
3258 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3259 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3260 argument instead of a const uint8_t *buf / int buf_size pair.
3262 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3263 Introduce the av_fifo_space() function.
3265 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3266 Move AVPacket declaration from libavformat/avformat.h to
3267 libavcodec/avcodec.h.
3269 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3270 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3271 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3272 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3273 PIX_FMT_BGR32_1 are now macros.
3274 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3275 Re-sort the enum PixelFormat list accordingly.
3276 This change breaks API/ABI backward compatibility.
3278 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3279 Add the enum PixelFormat values:
3280 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3281 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3283 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3284 The Mersenne Twister PRNG implemented through the av_random* functions
3285 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3288 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3289 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3290 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3291 and av_fifo_realloc2.
3292 In addition, the order of the function arguments of av_fifo_generic_read
3293 was changed to match av_fifo_generic_write.
3294 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3295 applications, they may not use sizeof() or directly access members.
3297 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3298 Introduce a new metadata API (see av_metadata_get() and friends).
3299 The old API is now deprecated and should not be used anymore. This especially
3300 includes the following structure fields:
3301 - AVFormatContext.title
3302 - AVFormatContext.author
3303 - AVFormatContext.copyright
3304 - AVFormatContext.comment
3305 - AVFormatContext.album
3306 - AVFormatContext.year
3307 - AVFormatContext.track
3308 - AVFormatContext.genre
3311 - AVProgram.provider_name
