This was likely caused by the build system changes in Bug 1393119, which accidentally caused us to start using a newer version of the OS X video capture code. I'm not sure at this point if we're going to revert to using an older version or continue with the newer version and fix the problems that have shown up. Long term, we want to use the new stuff.
Component: WebRTC → WebRTC: Audio/Video
Priority: -- → P2
Fix optional for 60 per triage team, will revaluate if numbers increase.
This should be fixed by the patches on Bug 1436959. It hasn't shown up since that landed, but it was pretty low frequency before, so it's hard to be completely certain it is actually fixed.
