This commit changes the approach with video timing. Previously,
we would (more-or-less) try to use every video frame from the content
in the output, hoping that they come at a constant frame rate.
This is not always the case, however. Here we preserve the PTS
of video frames, and then when one arrives we output whatever
DCP video frames we can (at the regular DCP frame rate).
Hopefully this will solve a range of sync problems, but it
could also introduce new ones.
Primitive auto-crop (#1477).2022-04-28T23:44:15ZCarl Hetheringtoncth@carlh.net2022-01-01T21:20:51Zurn:sha1:d5c059a2ff9bab5c2973db6bc4860591679dd42bGuess video range better when importing 2.14.x projects (#2227).2022-04-07T22:43:28ZCarl Hetheringtoncth@carlh.net2022-04-07T22:43:28Zurn:sha1:eeaca1992aa117fe3a2a4a079d8a20a01d88e933Don't scale chroma subsampled images to sizes that don't align with the subsampling (#1872).2021-10-03T21:41:02ZCarl Hetheringtoncth@carlh.net2021-10-03T19:22:14Zurn:sha1:969906f2dd6c5c144781861f53e2a0f6baefb9a3
There's a slightly odd effect when scaling e.g. YVU420 images to
odd and then even widths - there's a small but visible luminance
shift. I don't know why this happens, but keeping the scaling
sizes locked to the subsampling seems to help.
Differentiate requested and actual crop.2021-10-03T21:41:02ZCarl Hetheringtoncth@carlh.net2021-10-03T18:53:44Zurn:sha1:70b72b53eab0f247eb4dc605a2d669d4adb4e469
This is so we limit cropping to what is possible considering
chroma subsampling.
Add PixelQuanta to VideoContent.2021-10-03T21:41:02ZCarl Hetheringtoncth@carlh.net2021-10-03T00:02:12Zurn:sha1:c2a17a87868eba87072fc369102b2b3cd8905e5aRemove unused VideoContentProperty::SCALE and listen to CUSTOM_{RATIO,SIZE} instead.2021-09-19T21:00:22ZCarl Hetheringtoncth@carlh.net2021-09-19T20:19:38Zurn:sha1:8a3d5a7729e10a901132ff00efbd5d80e38b2455
::SCALE was sort-of being used, as it was emitted during examination of
video content, but it wasn't being emitted anywhere else (and CUSTOM_{RATIO,SIZE}
replace its functionality as far as I can see).
