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.

CanvasCaptureMediaStreamTrack.requestFrame()
Manually forces a frame to be captured and sent to the stream. This lets applications that wish to specify the frame capture times directly do so, if they specified a frameRate of 0 when calling captureStream().
