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

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

547 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
548 bump, and libavformat will behave as if it were always set.
549 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().
551 2016-03-20 - 8200b16a9c - lavu 55.50.100 / 55.21.0 - imgutils.h

558 2017-03-18 - 3796fb2692 - lavfi 6.77.100 - avfilter.h
559 Deprecate AVFilterGraph.resample_lavr_opts
560 It's never been used by avfilter nor passed to anything.

568 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
569 native decoder format. (The default value is not changed.)

637 Decoders now export the frame timestamp as AVFrame.pts. It was
638 previously exported as AVFrame.pkt_pts, which is now deprecated.

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

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

1868 reget_buffer(), avcodec_default_get_buffer(),
1869 avcodec_default_reget_buffer(), avcodec_default_release_buffer().
1870 Remove avcodec_default_free_buffers(), which should not have ever
1871 been called from outside of lavc.
1872 Deprecate the following AVFrame fields:
1873 * base -- is now stored in AVBufferRef
1874 * reference, type, buffer_hints -- are unnecessary in the new API
1875 * hwaccel_picture_private, owner, thread_opaque -- should not
1876 have been accessed from outside of lavc
1877 * qscale_table, qstride, qscale_type, mbskip_table, motion_val,

2036 For audio formats with fixed frame size, the last frame
2037 no longer needs to be padded with silence, libavcodec
2038 will handle this internally (effectively all encoders
2039 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

3187 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3188 Change the signature of avfilter_register() to make it return an
3189 int. This is required since now the registration operation may fail.
3191 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3192 Make the pixdesc.h API public.

3216 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3217 Add a pts field to AVSubtitle which gives the subtitle packet pts
3218 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

3221 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3222 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3223 major version. Use AV_PKT_FLAG_KEY instead.
3225 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3226 av_lockmgr_register() can be used to register a callback function
3227 that lavc (and in the future, libraries that depend on lavc) can use
3228 to implement mutexes. The application should provide a callback function
3229 that implements the AV_LOCK_* operations described in avcodec.h.
3230 When the lock manager is registered, FFmpeg is guaranteed to behave
3231 correctly in a multi-threaded application.
3233 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3234 av_free_packet() is no longer an inline function. It is now exported.
3236 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3237 Please use NULL instead. This has been supported since r16506
3238 (lavf > 52.23.1, lavc > 52.10.0).
3240 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3241 The old decoding functions are deprecated, all new code should use the
3242 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3243 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3244 argument instead of a const uint8_t *buf / int buf_size pair.
3246 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3247 Introduce the av_fifo_space() function.
3249 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3250 Move AVPacket declaration from libavformat/avformat.h to
3251 libavcodec/avcodec.h.
3253 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3254 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3255 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3256 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3257 PIX_FMT_BGR32_1 are now macros.
3258 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3259 Re-sort the enum PixelFormat list accordingly.
3260 This change breaks API/ABI backward compatibility.
3262 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3263 Add the enum PixelFormat values:
3264 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3265 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3267 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3268 The Mersenne Twister PRNG implemented through the av_random* functions
3269 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3272 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3273 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3274 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3275 and av_fifo_realloc2.
3276 In addition, the order of the function arguments of av_fifo_generic_read
3277 was changed to match av_fifo_generic_write.
3278 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3279 applications, they may not use sizeof() or directly access members.
3281 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3282 Introduce a new metadata API (see av_metadata_get() and friends).
3283 The old API is now deprecated and should not be used anymore. This especially
3284 includes the following structure fields:
3285 - AVFormatContext.title
3286 - AVFormatContext.author
3287 - AVFormatContext.copyright
3288 - AVFormatContext.comment
3289 - AVFormatContext.album
3290 - AVFormatContext.year
3291 - AVFormatContext.track
3292 - AVFormatContext.genre
3295 - AVProgram.provider_name
