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

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

762 Add requirement to bitstream filtering API that returned packets with

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

2994 Change the field types:
2995 enum PixelFormat format -> int format in AVFilterBuffer
2996 enum PixelFormat *formats -> int *formats in AVFilterFormats
2997 enum PixelFormat *format -> int format in AVFilterLink
2999 Change the function signatures:
3000 AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
3001 AVFilterFormats *avfilter_make_format_list(const int *fmts);
3003 int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
3004 int avfilter_add_format (AVFilterFormats **avff, int fmt);
3006 AVFilterFormats *avfilter_all_colorspaces(void); ->
3007 AVFilterFormats *avfilter_all_formats (enum AVMediaType type);
3009 This change breaks libavfilter API/ABI.

3197 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3198 Introduce the avfilter_next() function.
3200 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3201 Change the signature of avfilter_register() to make it return an
3202 int. This is required since now the registration operation may fail.
3204 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3205 Make the pixdesc.h API public.
3207 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3224 Add w and h fields to AVFilterPic.
3226 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3227 This is now an unsigned int instead of a signed int.
3229 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3230 Add a pts field to AVSubtitle which gives the subtitle packet pts
3231 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3232 not work right without this.
3234 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3235 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3236 major version. Use AV_PKT_FLAG_KEY instead.
3238 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3239 av_lockmgr_register() can be used to register a callback function
3240 that lavc (and in the future, libraries that depend on lavc) can use
3241 to implement mutexes. The application should provide a callback function
3242 that implements the AV_LOCK_* operations described in avcodec.h.
3243 When the lock manager is registered, FFmpeg is guaranteed to behave
3244 correctly in a multi-threaded application.
3246 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3247 av_free_packet() is no longer an inline function. It is now exported.
3249 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3250 Please use NULL instead. This has been supported since r16506
3251 (lavf > 52.23.1, lavc > 52.10.0).
3253 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3254 The old decoding functions are deprecated, all new code should use the
3255 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3256 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3257 argument instead of a const uint8_t *buf / int buf_size pair.
3259 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3260 Introduce the av_fifo_space() function.
3262 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3263 Move AVPacket declaration from libavformat/avformat.h to
3264 libavcodec/avcodec.h.
3266 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3267 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3268 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3269 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3270 PIX_FMT_BGR32_1 are now macros.
3271 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3272 Re-sort the enum PixelFormat list accordingly.
3273 This change breaks API/ABI backward compatibility.
3275 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3276 Add the enum PixelFormat values:
3277 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3278 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3280 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3281 The Mersenne Twister PRNG implemented through the av_random* functions
3282 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3285 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3286 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3287 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3288 and av_fifo_realloc2.
3289 In addition, the order of the function arguments of av_fifo_generic_read
3290 was changed to match av_fifo_generic_write.
3291 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3292 applications, they may not use sizeof() or directly access members.
3294 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3295 Introduce a new metadata API (see av_metadata_get() and friends).
3296 The old API is now deprecated and should not be used anymore. This especially
3297 includes the following structure fields:
3298 - AVFormatContext.title
3299 - AVFormatContext.author
3300 - AVFormatContext.copyright
3301 - AVFormatContext.comment
3302 - AVFormatContext.album
3303 - AVFormatContext.year
3304 - AVFormatContext.track
3305 - AVFormatContext.genre
3308 - AVProgram.provider_name
