Here is my code

include <highgui.h>

include <cv.h>

int main(int argc,char* argv) { IplImage frame; CvCapture* capture = cvCreateCameraCapture(-1); cvNamedWindow("Example 2",CV_WINDOW_AUTOSIZE); while(1) { frame = cvQueryFrame(capture); if(!frame) { printf("Error"); break; } cvShowImage("Example 2",frame); char c = cvWaitKey(33); if(c==27) break; } cvReleaseCapture(&capture); cvDestroyWindow("Example 2"); }

It shows the message "error" I am using opencv2.4.3 in Ubuntu 12.10 and my ide is Eclipse.
