Hi 

Below iam attaching the code 

import com.googlecode.javacv.CanvasFrame;
import com.googlecode.javacv.FFmpegFrameRecorder;
import com.googlecode.javacv.FrameGrabber;
import com.googlecode.javacv.FrameRecorder.Exception;
import com.googlecode.javacv.OpenCVFrameGrabber;
import com.googlecode.javacv.VideoInputFrameGrabber;
import com.googlecode.javacv.cpp.avutil;
import com.googlecode.javacv.cpp.opencv_core.IplImage;

public class CameraTest {

    /**
     * @param args
     */
    public static final String FILENAME = "C:\\Users\\LENOVO\\Pictures\\output.mp4";
    public static void main(String[] args)  {
        try{
            FrameGrabber grabber = new VideoInputFrameGrabber(0);

        grabber.start();
        IplImage grabbedImage = grabber.grab();

        CanvasFrame canvasFrame = new CanvasFrame("Cam");
        canvasFrame.setCanvasSize(grabbedImage.width(), grabbedImage.height());

        System.out.println("framerate = " + grabber.getFrameRate());

        FFmpegFrameRecorder recorder = new FFmpegFrameRecorder(FILENAME,  grabber.getImageWidth(),grabber.getImageHeight());
        grabber.setFrameRate(grabber.getFrameRate());
        recorder.setVideoCodec(13);
        recorder.setFormat("flv");
        recorder.setPixelFormat(avutil.AV_PIX_FMT_YUV420P);
        recorder.setFrameRate(30);
        recorder.setVideoBitrate(10 * 1024 * 1024);

        recorder.start();
        while (canvasFrame.isVisible() && (grabbedImage = grabber.grab()) != null) {
            canvasFrame.showImage(grabbedImage);
            recorder.record(grabbedImage);
        }
        recorder.stop();
        grabber.stop();
        canvasFrame.dispose();
        }catch(Exception e){
            e.printStackTrace();
        } catch (com.googlecode.javacv.FrameGrabber.Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

}

Iam getting output as

I followed below link, but unable to fix the issue even after placing the 
updated jars in classpath.

try to replace `FrameGrabber.createDefault(0)` with `new OpenCVFrameGrabber(0)`

Well, it works fine here, so I can't fix something that works fine with my 
machine. If you figure out why this is happening on your machine, please let me 
know so I can fix it, thank you.
