OpenCV parallelization with OpenMP

I am getting Fatal error in this code. I want to display the frames parallely. Need help.

include <cv.h>

include <cvaux.h>

include <iostream>

include <cxcore.h>

include <highgui.h>

include <omp.h>

using namespace cv; using namespace std;

int main(int argc, char *argv) { int no_of_frames = 0,i,j; int fps = 0; int mid_frame = 0; CvCapture capture = cvCaptureFromFile("/home/nagaraj/ImageVideo/tunnel.avi"); CvCapture* captureNew = cvCaptureFromFile("/home/nagaraj/ImageVideo/tunnel.avi"); if (capture == NULL) { printf("Error: Can't open video.\n"); return -1; } if (captureNew == NULL) { printf("Error: Can't open video.\n"); return -1; } fps = (int)cvGetCaptureProperty(capture,CV_CAP_PROP_FPS); no_of_frames = (int)cvGetCaptureProperty(capture,CV_CAP_PROP_FRAME_COUNT); mid_frame = no_of_frames/2; omp_set_num_threads(2);
