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

414 which can create the decoder context and allocate hardware frame automatically.
415 See AVCodecContext.hw_device_ctx and AVCodecContext.hw_frames_ctx. For D3D11,
416 the new AV_PIX_FMT_D3D11 pixfmt must be used with the new API.

459 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
460 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
461 set the Cuda device handle.
463 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

487 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
488 (via an entry named "rotate"). Use av_stream_get_side_data() with
489 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
490 av_display_rotation_get(). The same is done for muxing. Instead of adding a
491 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
492 to be added to the AVStream.

527 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
528 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
529 native decoder format. (The default value is not changed.)
531 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
532 Remove requirement to use AVOption or accessors to access certain fields
533 in AVFrame, AVCodecContext, and AVFormatContext that were previously
534 documented as "no direct access" allowed.

552 Deprecate struct vaapi_context and the vaapi.h installed header.

597 Decoders now export the frame timestamp as AVFrame.pts. It was
598 previously exported as AVFrame.pkt_pts, which is now deprecated.
600 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
601 and not the codec timebase.

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

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

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

3147 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3148 Change the signature of avfilter_register() to make it return an
3149 int. This is required since now the registration operation may fail.
3151 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3152 Make the pixdesc.h API public.

3176 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3177 Add a pts field to AVSubtitle which gives the subtitle packet pts
3178 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

3181 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3182 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3183 major version. Use AV_PKT_FLAG_KEY instead.
3185 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3186 av_lockmgr_register() can be used to register a callback function
3187 that lavc (and in the future, libraries that depend on lavc) can use
3188 to implement mutexes. The application should provide a callback function
3189 that implements the AV_LOCK_* operations described in avcodec.h.
3190 When the lock manager is registered, FFmpeg is guaranteed to behave
3191 correctly in a multi-threaded application.
3193 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3194 av_free_packet() is no longer an inline function. It is now exported.
3196 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3197 Please use NULL instead. This has been supported since r16506
3198 (lavf > 52.23.1, lavc > 52.10.0).
3200 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3201 The old decoding functions are deprecated, all new code should use the
3202 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3203 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3204 argument instead of a const uint8_t *buf / int buf_size pair.
3206 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3207 Introduce the av_fifo_space() function.
3209 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3210 Move AVPacket declaration from libavformat/avformat.h to
3211 libavcodec/avcodec.h.
3213 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3214 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3215 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3216 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3217 PIX_FMT_BGR32_1 are now macros.
3218 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3219 Re-sort the enum PixelFormat list accordingly.
3220 This change breaks API/ABI backward compatibility.
3222 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3223 Add the enum PixelFormat values:
3224 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3225 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3227 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3228 The Mersenne Twister PRNG implemented through the av_random* functions
3229 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3232 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3233 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3234 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3235 and av_fifo_realloc2.
3236 In addition, the order of the function arguments of av_fifo_generic_read
3237 was changed to match av_fifo_generic_write.
3238 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3239 applications, they may not use sizeof() or directly access members.
3241 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3242 Introduce a new metadata API (see av_metadata_get() and friends).
3243 The old API is now deprecated and should not be used anymore. This especially
3244 includes the following structure fields:
3245 - AVFormatContext.title
3246 - AVFormatContext.author
3247 - AVFormatContext.copyright
3248 - AVFormatContext.comment
3249 - AVFormatContext.album
3250 - AVFormatContext.year
3251 - AVFormatContext.track
3252 - AVFormatContext.genre
3255 - AVProgram.provider_name
