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

465 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
466 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
467 set the Cuda device handle.
469 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

493 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
494 (via an entry named "rotate"). Use av_stream_get_side_data() with
495 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
496 av_display_rotation_get(). The same is done for muxing. Instead of adding a
497 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
498 to be added to the AVStream.

513 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
514 bump, and libavformat will behave as if it were always set.
515 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().
517 2016-03-20 - 8200b16a9c - lavu 55.50.100 / 55.21.0 - imgutils.h

524 2017-03-18 - 3796fb2692 - lavfi 6.77.100 - avfilter.h
525 Deprecate AVFilterGraph.resample_lavr_opts
526 It's never been used by avfilter nor passed to anything.

533 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
534 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
535 native decoder format. (The default value is not changed.)
537 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
538 Remove requirement to use AVOption or accessors to access certain fields
539 in AVFrame, AVCodecContext, and AVFormatContext that were previously
540 documented as "no direct access" allowed.

558 Deprecate struct vaapi_context and the vaapi.h installed header.
559 Callers should set AVCodecContext.hw_frames_ctx instead.

603 Decoders now export the frame timestamp as AVFrame.pts. It was
604 previously exported as AVFrame.pkt_pts, which is now deprecated.
606 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
607 and not the codec timebase.

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

728 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
729 the reset of the ASS ReadOrder field on flush. This affects the content of

733 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
734 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
735 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
736 The default value for this option will change to "ass" at the next major
737 libavcodec version bump.
739 The current default is "ass_with_timings" for compatibility. This means that
740 all subtitles text decoders currently still output ASS with timings printed
741 as strings in the AVSubtitles.rects[N]->ass fields.
743 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
744 timing is limited to a 1/100 time base, so this is relevant for any subtitles
745 format needing a bigger one), ease timing adjustments, and prevents the need
746 of removing the timing from the decoded string yourself. This form is also
747 known as "the Matroska form". The timing information (start time, duration)
748 can be found in the AVSubtitles fields.

3153 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3154 Change the signature of avfilter_register() to make it return an
3155 int. This is required since now the registration operation may fail.
3157 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3158 Make the pixdesc.h API public.

3182 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3183 Add a pts field to AVSubtitle which gives the subtitle packet pts
3184 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

3187 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3188 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3189 major version. Use AV_PKT_FLAG_KEY instead.
3191 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3192 av_lockmgr_register() can be used to register a callback function
3193 that lavc (and in the future, libraries that depend on lavc) can use
3194 to implement mutexes. The application should provide a callback function
3195 that implements the AV_LOCK_* operations described in avcodec.h.
3196 When the lock manager is registered, FFmpeg is guaranteed to behave
3197 correctly in a multi-threaded application.
3199 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3200 av_free_packet() is no longer an inline function. It is now exported.
3202 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3203 Please use NULL instead. This has been supported since r16506
3204 (lavf > 52.23.1, lavc > 52.10.0).
3206 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3207 The old decoding functions are deprecated, all new code should use the
3208 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3209 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3210 argument instead of a const uint8_t *buf / int buf_size pair.
3212 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3213 Introduce the av_fifo_space() function.
3215 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3216 Move AVPacket declaration from libavformat/avformat.h to
3217 libavcodec/avcodec.h.
3219 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3220 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3221 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3222 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3223 PIX_FMT_BGR32_1 are now macros.
3224 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3225 Re-sort the enum PixelFormat list accordingly.
3226 This change breaks API/ABI backward compatibility.
3228 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3229 Add the enum PixelFormat values:
3230 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3231 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3233 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3234 The Mersenne Twister PRNG implemented through the av_random* functions
3235 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3238 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3239 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3240 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3241 and av_fifo_realloc2.
3242 In addition, the order of the function arguments of av_fifo_generic_read
3243 was changed to match av_fifo_generic_write.
3244 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3245 applications, they may not use sizeof() or directly access members.
3247 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3248 Introduce a new metadata API (see av_metadata_get() and friends).
3249 The old API is now deprecated and should not be used anymore. This especially
3250 includes the following structure fields:
3251 - AVFormatContext.title
3252 - AVFormatContext.author
3253 - AVFormatContext.copyright
3254 - AVFormatContext.comment
3255 - AVFormatContext.album
3256 - AVFormatContext.year
3257 - AVFormatContext.track
3258 - AVFormatContext.genre
3261 - AVProgram.provider_name
