OverconstrainedError

Secure context
This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

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.

Constructor

OverconstrainedError.OverconstrainedError(): Creates a new OverconstrainedError object.

Properties

OverconstrainedError.constraint Read only: Returns the constraint that was supplied in the constructor, meaning the constraint that was not satisfied.
OverconstrainedError.message Read only: Returns the text supplied in the constructor.
OverconstrainedError.name Read only: Will always return OverconstrainedError.

Methods

None.
