_capture = new Capture(0);
_capture.QueryFrame();
captureOutput = new VideoWriter(@"output.avi",(int)_capture.GetCaptureProperty(Emgu.CV.CvEnum.CAP_PROP.CV_CAP_PROP_FOURCC), (int)_capture.GetCaptureProperty(Emgu.CV.CvEnum.CAP_PROP.CV_CAP_PROP_FPS),(int)_capture.GetCaptureProperty(Emgu.CV.CvEnum.CAP_PROP.CV_CAP_PROP_FRAME_WIDTH), (int)_capture.GetCaptureProperty(Emgu.CV.CvEnum.CAP_PROP.CV_CAP_PROP_FRAME_HEIGHT), true);
Image frame = _capture.QueryFrame();
captureOutput.WriteFrame(frame);
