The OverconstrainedError interface of the Media Capture and Streams API indicates that the set of desired capabilities for the current MediaStreamTrack cannot currently be met. When this event is thrown on a MediaStreamTrack, it is muted until either the current constraints can be established or until satisfiable constraints are applied.
