CanvasCaptureMediaStreamTrack

The CanvasCaptureMediaStreamTrack interface represents the video track contained in a MediaStream being generated from a <canvas> following a call to HTMLCanvasElement.captureStream().

Part of the Media Capture and Streams API.

Properties

This interface inherits the properties of its parent, MediaStreamTrack.

CanvasCaptureMediaStreamTrack.canvas Read only

Returns the HTMLCanvasElement object whose surface is captured in real-time.

Methods

This interface inherits the methods of its parent, MediaStreamTrack.
