I executed a simple C++ program in Visual Studio2010 using OpencV version 2.2 to start the camera and display the video simaltaneously.But the camera gets started and only the window came as output and not the video capture simaltaneously..Here is my code.Is there any error in camera..Do we need to install any softwares..Please suggest as soon as possible.
#include "stdafx.h"
#include <cv.h>
#include <highgui.h>
#include <stdio.h>
#include <conio.h>
int main()
{
CvCapture* capture =0;
capture = cvCaptureFromCAM(0);
if(!capture)
{
printf("Capture failure\n");
return -1;
}
IplImage* frame=NULL;
cvNamedWindow("Video");
cvNamedWindow("Ball");
//iterate through each frames of the video
while(true)
{
frame = cvQueryFrame(capture);
if(!frame) break;
frame=cvCloneImage(frame);
cvShowImage("Video", frame);
//Clean up used images
cvReleaseImage(&frame);
//Wait 50mS
int c = cvWaitKey(10);
//If 'ESC' is pressed, break the loop
if((char)c==27 ) break;
}
cvDestroyAllWindows() ;
cvReleaseCapture(&capture);
return 0;
}
