Looks like the camera doesn't support some of the UVC controls (ie
brightness, contrast, hue, vflip, etc).

I've created a separate control list for the camera in the latest
revision, so, hopefully, it'll get a bit further (and possibly capture :)

It's also probably easier if you just used tvtime or xawtv to test
the webcam instead, since uvcview has issues with some of the cams,
and the args you passed to mplayer don't match the image format
returned by the camera (so, if you got passed that error, it'd still
fail trying to display an image).
