Part of the Media Capture and Streams API.


This interface inherits the properties of its parent, MediaStreamTrack.

CanvasCaptureMediaStreamTrack.canvas (en-US) 読取専用
Returns the HTMLCanvasElement object whose surface is captured in real-time.


This interface inherits the methods of its parent, MediaStreamTrack.

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().
