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

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

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

3221 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3222 Introduce the avfilter_next() function.
3224 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3225 Change the signature of avfilter_register() to make it return an
3226 int. This is required since now the registration operation may fail.
3228 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3229 Make the pixdesc.h API public.
3231 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
3232 Add a next field to AVFilter, this is used for simplifying the

3236 Add a description field to AVFilter.
3238 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()

3248 Add w and h fields to AVFilterPic.
3250 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3251 This is now an unsigned int instead of a signed int.
3253 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3254 Add a pts field to AVSubtitle which gives the subtitle packet pts
3255 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3256 not work right without this.
3258 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3259 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3260 major version. Use AV_PKT_FLAG_KEY instead.
3262 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3263 av_lockmgr_register() can be used to register a callback function
3264 that lavc (and in the future, libraries that depend on lavc) can use
3265 to implement mutexes. The application should provide a callback function
3266 that implements the AV_LOCK_* operations described in avcodec.h.
3267 When the lock manager is registered, FFmpeg is guaranteed to behave
3268 correctly in a multi-threaded application.
3270 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3271 av_free_packet() is no longer an inline function. It is now exported.
3273 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3274 Please use NULL instead. This has been supported since r16506
3275 (lavf > 52.23.1, lavc > 52.10.0).
3277 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3278 The old decoding functions are deprecated, all new code should use the
3279 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3280 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3281 argument instead of a const uint8_t *buf / int buf_size pair.
3283 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3284 Introduce the av_fifo_space() function.
3286 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3287 Move AVPacket declaration from libavformat/avformat.h to
3288 libavcodec/avcodec.h.
3290 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3291 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3292 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3293 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3294 PIX_FMT_BGR32_1 are now macros.
3295 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3296 Re-sort the enum PixelFormat list accordingly.
3297 This change breaks API/ABI backward compatibility.
3299 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3300 Add the enum PixelFormat values:
3301 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3302 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3304 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3305 The Mersenne Twister PRNG implemented through the av_random* functions
3306 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3309 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3310 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3311 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3312 and av_fifo_realloc2.
3313 In addition, the order of the function arguments of av_fifo_generic_read
3314 was changed to match av_fifo_generic_write.
3315 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3316 applications, they may not use sizeof() or directly access members.
3318 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3319 Introduce a new metadata API (see av_metadata_get() and friends).
3320 The old API is now deprecated and should not be used anymore. This especially
3321 includes the following structure fields:
3322 - AVFormatContext.title
3323 - AVFormatContext.author
3324 - AVFormatContext.copyright
3325 - AVFormatContext.comment
3326 - AVFormatContext.album
3327 - AVFormatContext.year
3328 - AVFormatContext.track
3329 - AVFormatContext.genre
3332 - AVProgram.provider_name
