Same problem on a Gateway NV5905h, believe it has to do with this: http://code.google.com/p/javacv/wiki/Windows7AndOpenCV

I cannot capture from my Webcam using opencv_highgui or OpenCVFrameGrabber

OpenCV uses Video for Windows, which does not always work properly under Windows 7. Use VideoInputFrameGrabber instead, which uses DirectShow and should always work correctly.

EDIT: WPILaptopCamera.java

package edu.wpi.first.wpijavacv;

import static com.googlecode.javacv.cpp.opencv_highgui.*;
/**

public class WPILaptopCamera extends WPIDisposable {
    CvCapture cam;

    public WPILaptopCamera() {
        cam = cvCreateCameraCapture(0);
    }

    public WPIColorImage getCurrentFrame(){
        return new WPIColorImage(cvQueryFrame(cam));
    }

    @Override
    protected void disposed() {
    }

}
