This is an image conversion problem: the SPCA501 is an image format, and the 
gb.v4l component prints it each time it cannot convert it to RGB. 

Apparently the component can convert only a few format to the one supported by 
Gambas: RGB & RGBA.

But I don't know what SPCA501 is exactly. A conversion library format is 
needed...
