I start using the C++ interface for OpenCV, instead of the old highgui C functions. Here is an example to do real time video capture from the default webcam.

#include "stdafx.h"
#include "cv.h"
#include "highgui.h"

using namespace cv;

int main(int, char**)
{
	VideoCapture cap(0);
	cap.set(CV_CAP_PROP_FRAME_WIDTH, 640);
	cap.set(CV_CAP_PROP_FRAME_HEIGHT, 480);
	if (!cap.isOpened())
		return -1;

	namedWindow("camera",CV_WINDOW_AUTOSIZE);
	while (true)
	{
		Mat frame;
		cap >> frame;
		imshow("camera", frame);
		if (waitKey(10) >= 0)
			break;
	}
	return 0;
}
