Imwrite does not saves image properly (Bug #4043)

Im trying to save image from webcam on a system on chip for every 5 secs.Everything is working fine but the output image is skewed. I have attached the output image. This is the code i used.

int main( int argc, const char** argv ) {
CvCapture* capture = 0;
Mat frame, frameCopy, image;

capture = cvCaptureFromCAM( 0 ); //0=default, -1=any camera, 1..99=your camera
    if(!capture) cout << "No camera detected" << endl;

if( capture )
{
        cout << "In capture ..." << endl;
        //for(;;)
    {
            IplImage* iplImg = cvQueryFrame( capture );
            frame = iplImg;
          //  if( frame.empty() )
            //    break;
            if( iplImg->origin == IPL_ORIGIN_TL )
                frame.copyTo( frameCopy );
            else
                flip( frame, frameCopy, 0 );
            imwrite( "/www/pages/resultok.bmp", frameCopy );
            if( waitKey( 10 ) >= 0 )
                cvReleaseCapture( &capture );
        }

waitKey(0);

return 0;
    }
