log if possible.

The weird thing is that this does *not* occur with personal Hangouts on my personal account on the same machine; there the camera video feed shows up normally. Rebooting multiple times did not fix the problem; neither did clearing cache; neither did wiping all local data, re-enrolling the device and acquiring a new corp cert. I tried switching back to stable channel in settings to see if that would fix it, but switching to stable does not seem to have actually caused the Chrome OS version on the device to change back. Techstop recommended switching back to stable since they only support stable, but I figured I should file a bug to flag the issue with beta in any case.
