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

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

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

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

3009 enum PixelFormat *formats -> int *formats in AVFilterFormats
3010 enum PixelFormat *format -> int format in AVFilterLink
3012 Change the function signatures:
3013 AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
3014 AVFilterFormats *avfilter_make_format_list(const int *fmts);
3016 int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
3017 int avfilter_add_format (AVFilterFormats **avff, int fmt);
3019 AVFilterFormats *avfilter_all_colorspaces(void); ->
3020 AVFilterFormats *avfilter_all_formats (enum AVMediaType type);
3022 This change breaks libavfilter API/ABI.

3208 Remove the next field from AVFilter, this is not anymore required.
3210 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3211 Introduce the avfilter_next() function.
3213 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3214 Change the signature of avfilter_register() to make it return an
3215 int. This is required since now the registration operation may fail.
3217 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3218 Make the pixdesc.h API public.
3220 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
3221 Add a next field to AVFilter, this is used for simplifying the

3225 Add a description field to AVFilter.
3227 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()

3237 Add w and h fields to AVFilterPic.
3239 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3240 This is now an unsigned int instead of a signed int.
3242 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3243 Add a pts field to AVSubtitle which gives the subtitle packet pts
3244 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3245 not work right without this.
3247 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3248 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3249 major version. Use AV_PKT_FLAG_KEY instead.
3251 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3252 av_lockmgr_register() can be used to register a callback function
3253 that lavc (and in the future, libraries that depend on lavc) can use
3254 to implement mutexes. The application should provide a callback function
3255 that implements the AV_LOCK_* operations described in avcodec.h.
3256 When the lock manager is registered, FFmpeg is guaranteed to behave
3257 correctly in a multi-threaded application.
3259 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3260 av_free_packet() is no longer an inline function. It is now exported.
3262 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3263 Please use NULL instead. This has been supported since r16506
3264 (lavf > 52.23.1, lavc > 52.10.0).
3266 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3267 The old decoding functions are deprecated, all new code should use the
3268 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3269 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3270 argument instead of a const uint8_t *buf / int buf_size pair.
3272 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3273 Introduce the av_fifo_space() function.
3275 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3276 Move AVPacket declaration from libavformat/avformat.h to
3277 libavcodec/avcodec.h.
3279 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3280 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3281 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3282 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3283 PIX_FMT_BGR32_1 are now macros.
3284 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3285 Re-sort the enum PixelFormat list accordingly.
3286 This change breaks API/ABI backward compatibility.
3288 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3289 Add the enum PixelFormat values:
3290 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3291 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3293 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3294 The Mersenne Twister PRNG implemented through the av_random* functions
3295 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3298 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3299 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3300 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3301 and av_fifo_realloc2.
3302 In addition, the order of the function arguments of av_fifo_generic_read
3303 was changed to match av_fifo_generic_write.
3304 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3305 applications, they may not use sizeof() or directly access members.
3307 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3308 Introduce a new metadata API (see av_metadata_get() and friends).
3309 The old API is now deprecated and should not be used anymore. This especially
3310 includes the following structure fields:
3311 - AVFormatContext.title
3312 - AVFormatContext.author
3313 - AVFormatContext.copyright
3314 - AVFormatContext.comment
3315 - AVFormatContext.album
3316 - AVFormatContext.year
3317 - AVFormatContext.track
3318 - AVFormatContext.genre
3321 - AVProgram.provider_name
