MediaDeviceInfo.groupId

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The groupId readonly property of the MediaDeviceInfo interface returns a DOMString that is a group identifier. Two devices have the same group identifier if they belong to the same physical device; for example a monitor with both a built-in camera and microphone.
