If the intent is actually grabbing the video stream, and embedding it in  
content, here is my proposal:

<object src="protocol:identifier/for/some/camera/">
   <param name="aperture-value" value="1.4" />
   <param name="shutter-speed" value="1/30" />

Implement File and FileReader on the <object> interface.

<object> (Or even <video>) could implement an interface for setting  
properties on the device
