I have a simple program.

include "cv.h"

include "highgui.h"

include "unistd.h"

include "iostream"

using namespace std;
using namespace cv;

int main(int argc, char** argv)
{
Mat frame;
VideoCapture capture;

capture.open(0);
if(!capture.isOpened()){ // check if we succeeded
cout << "Cannot open capture." << endl;
return -1;
}
capture.read(frame);
imwrite("img.jpg", frame);
capture.release();
return 0;
}

It usually works with a good photo

but sometimes it doesn't

How does one stop this frame splitting ?
