OverconstrainedError: OverconstrainedError() constructor

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The OverconstrainedError() constructor creates a new OverconstrainedError object which 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.

Syntax

js
new OverconstrainedError()

Parameters

constraint

The constraint that was not satisfied.

message Optional

Text for the error's message property. Defaults to an empty string.
