Comment (by Balling):
You did not read until comment #28 on doom9, it starts talking about
xvYCC.
>Not sure how specific figure in YUView should look for invalid colors
after such roundtrip
Depends what algoritm it uses to clip YCbCr out-of-gamut values. Typically
you need to use LittleCMS to see how to clip YCbCr color in xvYCC to
closest value representative in RGB. But you can enable zoom box in Yuview
and you will see actual values.
