but VideoCapture cap(0); is working for me..it opens the camera..
please anyone give solution..
#include "opencv2/highgui/highgui.hpp"
#include
#include
using namespace cv;
using namespace std;
int main( int argc, char** argv ) {
cvNamedWindow( "Example2", CV_WINDOW_AUTOSIZE );
CvCapture* capture = cvCaptureFromCAM(0);
IplImage* frame;
while(1) {
frame = cvQueryFrame( capture );
if( !frame ) break;
cvShowImage( "Example2", frame );
char c = cvWaitKey(33);
if( c == 27 ) break;
}
cvReleaseCapture( &capture );
cvDestroyWindow( "Example2" );
}
above shows the code...but when cv: :videocapture used cvQueryFrame gets error as there are no pointer in use...how to solve this..?
