This is a highly unusual error to see because it means that the device
and it's driver have the correct setup but the component itself is probably faulty. One thing to try is sending a 'colorspace rgba' message followed by a 'reset' to the object and see if that works.
It's possible that the camera driver only supports rgb output, and not the default YUV.
That was it! Now it works. Thanks very much for your help.
Why doesn't pd have a video settings menu, just as with midi and audio? Wouldn't it then be easier to debug this sort of problems?
Thanks again,
