Thanks for this hint – in fact what you describe is my current workaround but I think it should be possible to consciously set the capture devic resolution via Qt. Interestingly the current default resolution of the mac M1 cam is a square of 1552 x 1552 pixels but I typically use 16:9 rations.
I will investigate this in more detail and will possibly report a bug or at least non-ideal implementation in order to improve it. Let's see.
