sunxi frontend broken with scaled RGB888 #6

Closed libv closed 4 years ago

libv commented 4 years ago

When showing the no-input image, which is 720p, on a full HD display, the overlay scales, so the frontend is marshalled in. With our current setup, this leads to a strangely white display, pointing to an issue between the allwinner display engine "frontend" (scaler) and backend (composer).

Frontend (colour-space-conversion/scaler) had its scaling phase register nulled, ruining upscaling. Fixed in upcoming patch series in issue #16
