[PD] Is it possible to change webcam's resolution in Mac OS?

[Max]

I'm guessing this is a colorspace issue. try [pix_rgba] right after [pix_video].

I can live (unhappy) with having to do it manually every time, and I can trigger the settings dialog to open by sending the "dialog format" message to [pix_video] (unfortunately the values are not saved)
