#include <opencv2/opencv.hpp>

int main()
{
cv::VideoCapture cap1(1);
cv::VideoCapture cap2(2);

if(!cap1.isOpened())
{
  std::cout << "Cannot open the video cam [1]" << std::endl;
  return -1;
}

if(!cap2.isOpened())
{
  std::cout << "Cannot open the video cam [2]" << std::endl;
  return -1;
}

cap1.set(CV_CAP_PROP_FPS, 15);
cap2.set(CV_CAP_PROP_FPS, 15);

// Values taken from output of Version 1 and used to setup the exact same parameters with the exact same values!
cap1.set(CV_CAP_PROP_FRAME_WIDTH, 640);
cap1.set(CV_CAP_PROP_FRAME_HEIGHT, 480);
cap2.set(CV_CAP_PROP_FRAME_WIDTH, 640);
cap2.set(CV_CAP_PROP_FRAME_HEIGHT, 480);    

cv::namedWindow("cam[1]",CV_WINDOW_AUTOSIZE);
cv::namedWindow("cam[2]",CV_WINDOW_AUTOSIZE);

while(1)    
{    
  cv::Mat frame1, frame2;    
  bool bSuccess1 = cap1.read(frame1);    
  bool bSuccess2 = cap2.read(frame2);

  if (!bSuccess1)
  {
    std::cout << "Cannot read a frame from video stream [1]" << std::endl;
    break;
  }

  if (!bSuccess2)
  {
    std::cout << "Cannot read a frame from video stream [2]" << std::endl;
    break;
  }

  cv::imshow("cam[1]", frame1);
  cv::imshow("cam[2]", frame2);

  if(cv::waitKey(30) == 27)
  {
    std::cout << "ESC key is pressed by user" << std::endl;
    break;
  }
}

    return 0;
}
