Note to
(1) Turn on when treating Cb and Cr separately because two pixels worth of data is required. Alternatively, you can turn this parameter off and use
(2) This option can be useful if you want to split a subsampled color plane from a fully sampled color plane. The subsampled color plane can then
(3) Turn on when stream contains two subsampled channels. For other MegaCore functions to be able to treat these channels as two fully sampled
