297 Users of this library are asked to migrate to libswresample, which, as well as
298 providing more functionality, is faster and has higher accuracy.

474 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
475 (via an entry named "rotate"). Use av_stream_get_side_data() with
476 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
477 av_display_rotation_get(). The same is done for muxing. Instead of adding a
478 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
479 to be added to the AVStream.

584 Decoders now export the frame timestamp as AVFrame.pts. It was
585 previously exported as AVFrame.pkt_pts, which is now deprecated.
587 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
588 and not the codec timebase.

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

709 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing

714 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
715 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
716 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
717 The default value for this option will change to "ass" at the next major
718 libavcodec version bump.
720 The current default is "ass_with_timings" for compatibility. This means that
721 all subtitles text decoders currently still output ASS with timings printed
722 as strings in the AVSubtitles.rects[N]->ass fields.
724 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
725 timing is limited to a 1/100 time base, so this is relevant for any subtitles
726 format needing a bigger one), ease timing adjustments, and prevents the need
727 of removing the timing from the decoded string yourself. This form is also
728 known as "the Matroska form". The timing information (start time, duration)
729 can be found in the AVSubtitles fields.

3131 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3132 Introduce the avfilter_next() function.
3134 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3135 Change the signature of avfilter_register() to make it return an
3136 int. This is required since now the registration operation may fail.
3138 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3139 Make the pixdesc.h API public.
3141 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3163 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3164 Add a pts field to AVSubtitle which gives the subtitle packet pts
3165 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3166 not work right without this.
3168 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3169 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3170 major version. Use AV_PKT_FLAG_KEY instead.
3172 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3173 av_lockmgr_register() can be used to register a callback function
3174 that lavc (and in the future, libraries that depend on lavc) can use
3175 to implement mutexes. The application should provide a callback function
3176 that implements the AV_LOCK_* operations described in avcodec.h.
3177 When the lock manager is registered, FFmpeg is guaranteed to behave
3178 correctly in a multi-threaded application.
3180 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3181 av_free_packet() is no longer an inline function. It is now exported.
3183 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3184 Please use NULL instead. This has been supported since r16506
3185 (lavf > 52.23.1, lavc > 52.10.0).
3187 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3188 The old decoding functions are deprecated, all new code should use the
3189 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3190 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3191 argument instead of a const uint8_t *buf / int buf_size pair.
3193 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3194 Introduce the av_fifo_space() function.
3196 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3197 Move AVPacket declaration from libavformat/avformat.h to
3198 libavcodec/avcodec.h.
3200 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3201 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3202 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3203 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3204 PIX_FMT_BGR32_1 are now macros.
3205 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3206 Re-sort the enum PixelFormat list accordingly.
3207 This change breaks API/ABI backward compatibility.
3209 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3210 Add the enum PixelFormat values:
3211 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3212 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3214 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3215 The Mersenne Twister PRNG implemented through the av_random* functions
3216 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3219 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3220 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3221 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3222 and av_fifo_realloc2.
3223 In addition, the order of the function arguments of av_fifo_generic_read
3224 was changed to match av_fifo_generic_write.
3225 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3226 applications, they may not use sizeof() or directly access members.
3228 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3229 Introduce a new metadata API (see av_metadata_get() and friends).
3230 The old API is now deprecated and should not be used anymore. This especially
3231 includes the following structure fields:
3232 - AVFormatContext.title
3233 - AVFormatContext.author
3234 - AVFormatContext.copyright
3235 - AVFormatContext.comment
3236 - AVFormatContext.album
3237 - AVFormatContext.year
3238 - AVFormatContext.track
3239 - AVFormatContext.genre
3242 - AVProgram.provider_name
