Hallo!
- does pdp work in RGB(A) only?
No, the standard colorspace is YUV.
- when Gem is in yuv mode, is it 24 bits per pixel .. or is it 16 bits
per pixel, as in YUV4:2:2 .... where 2 adjacent pixels share UV data ?
The standard YUV-mode in Gem is YUV422 (at least the code says that) and one pixel is 8 bit.
