  Note about camera selection in Mac:
  List functionality (GSCapture.list(), etc.) still not working.
  
  But it is possible to select the camera, althouth it is a little
  tricky right now. Under 32 bits, GSVideo uses a capture plugin (osxvideosrc)
  that accepts a camera specification as a sequence grabber input device in 
  format "sgname:input#". For example:
  
  cam = new GSCapture(this, 640, 480, "USB Video Class Video:0");  
  
  Under 64 bits, GSVideo uses a different capture plugin (qtkitvideoserc)
  which only accepts a device index for the time being:
  
  cam = new GSCapture(this, 640, 480, "0");
  cam = new GSCapture(this, 640, 480, "1");  
  etc.
  
  Note that the index must be given as a string, to maintain consistency with
  the API.
