uvccapture is really setup just to create JPEGs by using the MJPEG frames. 
Since its built on the luvcview core, the YUYV capture is present in the 
code, but I've not implemented a method to get it out. I'll dig through and 
see if I can add a YUYV dump, but I'm not even sure of the file formatting, 
so I'll have to do a little research. At the very least I'll disallow 
>960x720 in MJPEG mode, and make a note in the README and usage output. 
Patches are always welcome to help implementing this.
