 // A virtualized VideoCaptureDevice that captures the displayed contents of a
 // WebContents (i.e., the composition of an entire render frame tree), producing
 // a stream of video frames. As such, WebContentsVideoCaptureDevice is only
 // supported on platforms that use the Chromium compositor, have a
 // content::RenderWidgetHostView implementation that supports frame subscription
 // (via BeginFrameSubscription()), and can perform read-back into
 // media::VideoFrames (i.e.,
-// RenderWidgetHostViewBase::CopyFromCompositingSurfaceToVideoFrame() is
-// functional).
+// RenderWidgetHostViewBase::CopyFromSurfaceToVideoFrame() is functional).
 //
 // An instance is created by providing a device_id.  The device_id contains
 // information necessary for finding a WebContents instance.  From then on,
 // WebContentsVideoCaptureDevice will capture from the RenderWidgetHost that
 // encompasses the currently active RenderFrameHost tree for that that
 // WebContents instance.  As the RenderFrameHost tree mutates (e.g., due to page
 // navigations, or crashes/reloads), capture will continue without interruption.
