MediaStreamTrack: label property
The label read-only property of the MediaStreamTrack interface returns a string containing a user agent-assigned label that identifies the track source, as in "internal microphone".
The string may be left empty and is empty as long as no source has been connected. When the track is disassociated from its source, the label is not changed.
