Subject: Bug 1572281 - Remove audio device change notifications from video
capture in Linux. r=dminor
Video capture used to provide device change notifications for audio and video devices. From no w on, CubebDeviceEnumerator will provide audio device change notifications thus video capture is updated to notify only changes of the video device. This is the Linux part.
