OverconstrainedError 接口在 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.

构造函数

OverconstrainedError.OverconstrainedError()

创建新的 OverconstrainedError 对象。

特性

OverconstrainedError.constraint 只读

Returns the constraint that was supplied in the constructor, meaning the constraint that was not satisfied.

OverconstrainedError.message 只读

Returns the text supplied in the constructor.

OverconstrainedError.name 只读

Will always return OverconstrainedError .

方法

None.
