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

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

765 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
766 the reset of the ASS ReadOrder field on flush. This affects the content of
767 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
770 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
771 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
772 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
773 The default value for this option will change to "ass" at the next major
774 libavcodec version bump.
776 The current default is "ass_with_timings" for compatibility. This means that
777 all subtitles text decoders currently still output ASS with timings printed
778 as strings in the AVSubtitles.rects[N]->ass fields.
780 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
781 timing is limited to a 1/100 time base, so this is relevant for any subtitles
782 format needing a bigger one), ease timing adjustments, and prevents the need
783 of removing the timing from the decoded string yourself. This form is also
784 known as "the Matroska form". The timing information (start time, duration)
785 can be found in the AVSubtitles fields.

1871 reget_buffer(), avcodec_default_get_buffer(),
1872 avcodec_default_reget_buffer(), avcodec_default_release_buffer().
1873 Remove avcodec_default_free_buffers(), which should not have ever
1874 been called from outside of lavc.
1875 Deprecate the following AVFrame fields:
1876 * base -- is now stored in AVBufferRef
1877 * reference, type, buffer_hints -- are unnecessary in the new API
1878 * hwaccel_picture_private, owner, thread_opaque -- should not
1879 have been accessed from outside of lavc
1880 * qscale_table, qstride, qscale_type, mbskip_table, motion_val,

2039 For audio formats with fixed frame size, the last frame

3190 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3191 Change the signature of avfilter_register() to make it return an
3192 int. This is required since now the registration operation may fail.
3194 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3195 Make the pixdesc.h API public.

3219 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3220 Add a pts field to AVSubtitle which gives the subtitle packet pts
3221 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

3224 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3225 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3226 major version. Use AV_PKT_FLAG_KEY instead.
3228 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3229 av_lockmgr_register() can be used to register a callback function
3230 that lavc (and in the future, libraries that depend on lavc) can use
3231 to implement mutexes. The application should provide a callback function
3232 that implements the AV_LOCK_* operations described in avcodec.h.
3233 When the lock manager is registered, FFmpeg is guaranteed to behave
3234 correctly in a multi-threaded application.
3236 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3237 av_free_packet() is no longer an inline function. It is now exported.
3239 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3240 Please use NULL instead. This has been supported since r16506
3241 (lavf > 52.23.1, lavc > 52.10.0).
3243 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3244 The old decoding functions are deprecated, all new code should use the
3245 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3246 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3247 argument instead of a const uint8_t *buf / int buf_size pair.
3249 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3250 Introduce the av_fifo_space() function.
3252 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3253 Move AVPacket declaration from libavformat/avformat.h to
3254 libavcodec/avcodec.h.
3256 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3257 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3258 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3259 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3260 PIX_FMT_BGR32_1 are now macros.
3261 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3262 Re-sort the enum PixelFormat list accordingly.
3263 This change breaks API/ABI backward compatibility.
3265 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3266 Add the enum PixelFormat values:
3267 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3268 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3270 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3271 The Mersenne Twister PRNG implemented through the av_random* functions
3272 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3275 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3276 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3277 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3278 and av_fifo_realloc2.
3279 In addition, the order of the function arguments of av_fifo_generic_read
3280 was changed to match av_fifo_generic_write.
3281 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3282 applications, they may not use sizeof() or directly access members.
3284 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3285 Introduce a new metadata API (see av_metadata_get() and friends).
3286 The old API is now deprecated and should not be used anymore. This especially
3287 includes the following structure fields:
3288 - AVFormatContext.title
3289 - AVFormatContext.author
3290 - AVFormatContext.copyright
3291 - AVFormatContext.comment
3292 - AVFormatContext.album
3293 - AVFormatContext.year
3294 - AVFormatContext.track
3295 - AVFormatContext.genre
3298 - AVProgram.provider_name
