Hey I have some trouble in obtaining live feed using open-cv

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

int main()
{
    char c;
    CvCapture* camera = cvCreateCameraCapture(-1);
    cvNamedWindow("live feed",CV_WINDOW_AUTOSIZE);
    IplImage* frame;
    while(1)
    {
        if(!frame)
            break;
        frame = cvQueryFrame(camera);
        cvShowImage("live feed",frame);
        c = cvWaitKey(33);
        if(c==27)
            break;
    }
}

Its breaking without scanning.Can you tell what is wrong.

scanning ?
I think your camera is not working properly. and your code is also incorrect.

#include<opencv2/highgui/highgui.hpp>
#include<stdio.h>

int main()
{
    CvCapture* cam = cvCreateCameraCapture(-1);
    cvNamedWindow("livefeed",CV_WINDOW_AUTOSIZE);
    IplImage* frame;
     
    if (!frame)
    {
        printf("frame NULL");
    }
    else
    {
        printf("frame not NULL");
    }
 
    return (0);
}

try this code. compare it with your code. and see where you have done the mistake.
