Chrome allows you to store in the preferences that a certain site is 
trusted with your camera, in which case popups don't happen; you can 
also select this from the popup dialog, so that future dialogs don't happen.

If a site is trusted, you don't need the "popup:off" argument to 
getUserMedia; if a site is untrusted, specifying "popup:off" shouldn't 
allow the site to grab your camera - it would be a security violation.
