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

496 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
497 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
498 set the Cuda device handle.
500 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

523 2017-03-27 - ddef3d902f - lavf 57.68.100 - avformat.h
524 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
525 (via an entry named "rotate"). Use av_stream_get_side_data() with
526 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
527 av_display_rotation_get(). The same is done for muxing. Instead of adding a
528 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
529 to be added to the AVStream.

544 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
545 bump, and libavformat will behave as if it were always set.
546 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().

556 Deprecate AVFilterGraph.resample_lavr_opts
557 It's never been used by avfilter nor passed to anything.

565 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
566 native decoder format. (The default value is not changed.)
568 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
569 Remove requirement to use AVOption or accessors to access certain fields
570 in AVFrame, AVCodecContext, and AVFormatContext that were previously
571 documented as "no direct access" allowed.

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

634 Decoders now export the frame timestamp as AVFrame.pts. It was
635 previously exported as AVFrame.pkt_pts, which is now deprecated.
637 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
638 and not the codec timebase.

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

759 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
760 the reset of the ASS ReadOrder field on flush. This affects the content of
761 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
764 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
765 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
766 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
767 The default value for this option will change to "ass" at the next major
768 libavcodec version bump.
770 The current default is "ass_with_timings" for compatibility. This means that
771 all subtitles text decoders currently still output ASS with timings printed
772 as strings in the AVSubtitles.rects[N]->ass fields.
774 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
775 timing is limited to a 1/100 time base, so this is relevant for any subtitles
776 format needing a bigger one), ease timing adjustments, and prevents the need
777 of removing the timing from the decoded string yourself. This form is also
778 known as "the Matroska form". The timing information (start time, duration)
779 can be found in the AVSubtitles fields.

1865 reget_buffer(), avcodec_default_get_buffer(),
1866 avcodec_default_reget_buffer(), avcodec_default_release_buffer().
1867 Remove avcodec_default_free_buffers(), which should not have ever
1868 been called from outside of lavc.
1869 Deprecate the following AVFrame fields:
1870 * base -- is now stored in AVBufferRef
1871 * reference, type, buffer_hints -- are unnecessary in the new API
1872 * hwaccel_picture_private, owner, thread_opaque -- should not
1873 have been accessed from outside of lavc
1874 * qscale_table, qstride, qscale_type, mbskip_table, motion_val,

2033 For audio formats with fixed frame size, the last frame
2034 no longer needs to be padded with silence, libavcodec
2035 will handle this internally (effectively all encoders
2036 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

3184 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3185 Change the signature of avfilter_register() to make it return an
3186 int. This is required since now the registration operation may fail.
3188 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3189 Make the pixdesc.h API public.

3213 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3214 Add a pts field to AVSubtitle which gives the subtitle packet pts
3215 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3216 not work right without this.
3218 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3219 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3220 major version. Use AV_PKT_FLAG_KEY instead.
3222 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3223 av_lockmgr_register() can be used to register a callback function
3224 that lavc (and in the future, libraries that depend on lavc) can use
3225 to implement mutexes. The application should provide a callback function
3226 that implements the AV_LOCK_* operations described in avcodec.h.
3227 When the lock manager is registered, FFmpeg is guaranteed to behave
3228 correctly in a multi-threaded application.
3230 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3231 av_free_packet() is no longer an inline function. It is now exported.
3233 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3234 Please use NULL instead. This has been supported since r16506
3235 (lavf > 52.23.1, lavc > 52.10.0).
3237 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3238 The old decoding functions are deprecated, all new code should use the
3239 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3240 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3241 argument instead of a const uint8_t *buf / int buf_size pair.
3243 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3244 Introduce the av_fifo_space() function.
3246 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3247 Move AVPacket declaration from libavformat/avformat.h to
3248 libavcodec/avcodec.h.
3250 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3251 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3252 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3253 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3254 PIX_FMT_BGR32_1 are now macros.
3255 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3256 Re-sort the enum PixelFormat list accordingly.
3257 This change breaks API/ABI backward compatibility.
3259 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3260 Add the enum PixelFormat values:
3261 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3262 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3264 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3265 The Mersenne Twister PRNG implemented through the av_random* functions
3266 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3269 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3270 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3271 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3272 and av_fifo_realloc2.
3273 In addition, the order of the function arguments of av_fifo_generic_read
3274 was changed to match av_fifo_generic_write.
3275 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3276 applications, they may not use sizeof() or directly access members.
3278 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3279 Introduce a new metadata API (see av_metadata_get() and friends).
3280 The old API is now deprecated and should not be used anymore. This especially
3281 includes the following structure fields:
3282 - AVFormatContext.title
3283 - AVFormatContext.author
3284 - AVFormatContext.copyright
3285 - AVFormatContext.comment
3286 - AVFormatContext.album
3287 - AVFormatContext.year
3288 - AVFormatContext.track
3289 - AVFormatContext.genre
3292 - AVProgram.provider_name
