491 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
492 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
493 set the Cuda device handle.
495 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

519 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
520 (via an entry named "rotate"). Use av_stream_get_side_data() with
521 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
522 av_display_rotation_get(). The same is done for muxing. Instead of adding a
523 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
524 to be added to the AVStream.

629 Decoders now export the frame timestamp as AVFrame.pts. It was
630 previously exported as AVFrame.pkt_pts, which is now deprecated.
632 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
633 and not the codec timebase.

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

760 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
761 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
762 The default value for this option will change to "ass" at the next major
763 libavcodec version bump.
765 The current default is "ass_with_timings" for compatibility. This means that
766 all subtitles text decoders currently still output ASS with timings printed
767 as strings in the AVSubtitles.rects[N]->ass fields.
769 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
770 timing is limited to a 1/100 time base, so this is relevant for any subtitles
771 format needing a bigger one), ease timing adjustments, and prevents the need
772 of removing the timing from the decoded string yourself. This form is also
773 known as "the Matroska form". The timing information (start time, duration)
774 can be found in the AVSubtitles fields.

1868 have been accessed from outside of lavc

3179 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3180 Change the signature of avfilter_register() to make it return an
3181 int. This is required since now the registration operation may fail.
3183 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3184 Make the pixdesc.h API public.

3208 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3209 Add a pts field to AVSubtitle which gives the subtitle packet pts
3210 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

3213 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3214 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3215 major version. Use AV_PKT_FLAG_KEY instead.
3217 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3218 av_lockmgr_register() can be used to register a callback function
3219 that lavc (and in the future, libraries that depend on lavc) can use
3220 to implement mutexes. The application should provide a callback function
3221 that implements the AV_LOCK_* operations described in avcodec.h.
3222 When the lock manager is registered, FFmpeg is guaranteed to behave
3223 correctly in a multi-threaded application.
3225 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3226 av_free_packet() is no longer an inline function. It is now exported.
3228 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3229 Please use NULL instead. This has been supported since r16506
3230 (lavf > 52.23.1, lavc > 52.10.0).
3232 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3233 The old decoding functions are deprecated, all new code should use the
3234 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3235 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3236 argument instead of a const uint8_t *buf / int buf_size pair.
3238 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3239 Introduce the av_fifo_space() function.
3241 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3242 Move AVPacket declaration from libavformat/avformat.h to
3243 libavcodec/avcodec.h.
3245 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3246 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3247 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3248 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3249 PIX_FMT_BGR32_1 are now macros.
3250 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3251 Re-sort the enum PixelFormat list accordingly.
3252 This change breaks API/ABI backward compatibility.
3254 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3255 Add the enum PixelFormat values:
3256 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3257 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3259 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3260 The Mersenne Twister PRNG implemented through the av_random* functions
3261 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3264 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3265 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3266 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3267 and av_fifo_realloc2.
3268 In addition, the order of the function arguments of av_fifo_generic_read
3269 was changed to match av_fifo_generic_write.
3270 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3271 applications, they may not use sizeof() or directly access members.
3273 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3274 Introduce a new metadata API (see av_metadata_get() and friends).
3275 The old API is now deprecated and should not be used anymore. This especially
3276 includes the following structure fields:
3277 - AVFormatContext.title
3278 - AVFormatContext.author
3279 - AVFormatContext.copyright
3280 - AVFormatContext.comment
3281 - AVFormatContext.album
3282 - AVFormatContext.year
3283 - AVFormatContext.track
3284 - AVFormatContext.genre
3287 - AVProgram.provider_name
