+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 now 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.
+
+Differential Revision: https://phabricator.services.mozilla.com/D46272
+Mercurial Revision: https://hg.mozilla.org/mozilla-central/rev/7bf7263db30b794139332691f4fbc98b4bfcfdd7
