The {{domxref("CanvasCaptureMediaStreamTrack")}} canvas읽기 전용 속성은 프레임이 캡쳐되는{{domxref("HTMLCanvasElement")}} 를 반환한다.

+ +

구문

+var canvasElt = document.getElementsByTagName("canvas")[0];
+
+// stream 얻기
+var stream = canvasElt.captureStream(25); // 25 FPS

{{APIRef("Media Capture and Streams")}}
+ +

The CanvasCaptureMediaStreamTrack interface represents the video track contained in a {{domxref("MediaStream")}} being generated from a {{HTMLElement("canvas")}} following a call to {{domxref("HTMLCanvasElement.captureStream()")}}.

+ +

Part of the Media Capture and Streams API.

+ +

Properties

+ +

This interface inherits the properties of its parent, {{domxref("MediaStreamTrack")}}.

+ +
+
{{domxref("CanvasCaptureMediaStreamTrack.canvas")}} {{readonlyInline}}
+
Returns the {{domxref("HTMLCanvasElement")}} object whose surface is captured in real-time.
+
+ +

Methods

+ +

This interface inherits the methods of its parent, {{domxref("MediaStreamTrack")}}.

+ +
+
{{domxref("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 {{domxref("HTMLCanvasElement.captureStream", "captureStream()")}}.
+
+ +

{{APIRef("Media Capture and Streams")}}
+ +

The {{domxref("CanvasCaptureMediaStreamTrack")}} 의 메서드 requestFrame() 은 canvas에서 프레임을 캡처하여 stream으로 보낼 것을 요청한다. 렌더링 타이밍과 프레임 캡처를 섬세하게 제어해야하는 애플리케이션은  requestFrame() 을 사용해 프레임을 캡처할 시기를 직접 지정할 수 있다.

+ +

프레임의 자동 캡처를 방지하려면 requestFrame() 이 호출될 때만 프레임이 캡처되도록 {{domxref("HTMLCanvasElement.captureStream", "captureStream()")}} 메서드에 값을 0으로 지정하세요.

+ +

구문

+ +
stream.requestFrame();
+
+ +

Return 값

+ +

undefined

+ +

참고 사항

+ +

현재 사양에는 canvas가 origin-clean 이 아닌 경우 예외를 발생시키지 않는다는 점을 지적하는 문제가 플래그로 표시되어 있다. 이것은 앞으로 바뀔 수 있기 때문에 계획을 미리 세우고  SecurityError (적용될 수 있는 구체적인 오류는 사양에 언급되어 있지 않지만, 유력한 후보임)와 같은 예외사항을 지켜보는 것이 좋다.

+ +

예시

+ +
// 캡처할 canvas 요소 찾기
+var canvasElt = document.getElementsByTagName("canvas")[0];
+
+// stream 가져오기
+var stream = canvasElt.captureStream(25); // 25 FPS
+
+// canvas의 현재 상태를 프레임으로 stream에 보내기
+stream.getVideoTracks()[0].requestFrame();
