How does hue adjusting works?
Hue adjustment is done on YCrCb data stream;
It can be done in CP-core by:
Cb_out = Cb*cos(hue) + Cr*sin(hue)
Cr_out = Cr*cos(hue) - Cb*sin(hue)
I'm attaching example spreadsheet with rotation calculated from measured video
stream. 8-bit YCrCb 444 stream used with EVAL-ADV7611EB1Z.
