CanvasCaptureMediaStreamTrack
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The CanvasCaptureMediaStreamTrack interface of the Media Capture and Streams API represents the video track contained in a MediaStream being generated from a <canvas> following a call to HTMLCanvasElement.captureStream().
Instance properties
This interface inherits the properties of its parent, MediaStreamTrack.
CanvasCaptureMediaStreamTrack.canvasRead only-
Returns the
HTMLCanvasElementobject whose surface is captured in real-time.
Instance 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
frameRateof 0 when callingcaptureStream().
