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

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

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

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

3024 int avfilter_add_format (AVFilterFormats **avff, int fmt);
3026 AVFilterFormats *avfilter_all_colorspaces(void); ->
3027 AVFilterFormats *avfilter_all_formats (enum AVMediaType type);

3217 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3218 Introduce the avfilter_next() function.
3220 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3221 Change the signature of avfilter_register() to make it return an
3222 int. This is required since now the registration operation may fail.
3224 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3225 Make the pixdesc.h API public.
3227 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3244 Add w and h fields to AVFilterPic.
3246 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3247 This is now an unsigned int instead of a signed int.
3249 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3250 Add a pts field to AVSubtitle which gives the subtitle packet pts
3251 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3252 not work right without this.
3254 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3255 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3256 major version. Use AV_PKT_FLAG_KEY instead.
3258 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3259 av_lockmgr_register() can be used to register a callback function
3260 that lavc (and in the future, libraries that depend on lavc) can use
3261 to implement mutexes. The application should provide a callback function
3262 that implements the AV_LOCK_* operations described in avcodec.h.
3263 When the lock manager is registered, FFmpeg is guaranteed to behave
3264 correctly in a multi-threaded application.
3266 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3267 av_free_packet() is no longer an inline function. It is now exported.
3269 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3270 Please use NULL instead. This has been supported since r16506
3271 (lavf > 52.23.1, lavc > 52.10.0).
3273 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3274 The old decoding functions are deprecated, all new code should use the
3275 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3276 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3277 argument instead of a const uint8_t *buf / int buf_size pair.
3279 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3280 Introduce the av_fifo_space() function.
3282 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3283 Move AVPacket declaration from libavformat/avformat.h to
3284 libavcodec/avcodec.h.
3286 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3287 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3288 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3289 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3290 PIX_FMT_BGR32_1 are now macros.
3291 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3292 Re-sort the enum PixelFormat list accordingly.
3293 This change breaks API/ABI backward compatibility.
3295 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3296 Add the enum PixelFormat values:
3297 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3298 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3300 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3301 The Mersenne Twister PRNG implemented through the av_random* functions
3302 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3305 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3306 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3307 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3308 and av_fifo_realloc2.
3309 In addition, the order of the function arguments of av_fifo_generic_read
3310 was changed to match av_fifo_generic_write.
3311 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3312 applications, they may not use sizeof() or directly access members.
3314 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3315 Introduce a new metadata API (see av_metadata_get() and friends).
3316 The old API is now deprecated and should not be used anymore. This especially
3317 includes the following structure fields:
3318 - AVFormatContext.title
3319 - AVFormatContext.author
3320 - AVFormatContext.copyright
3321 - AVFormatContext.comment
3322 - AVFormatContext.album
3323 - AVFormatContext.year
3324 - AVFormatContext.track
3325 - AVFormatContext.genre
3328 - AVProgram.provider_name
