I'm accessing the front and back cameras of my surface pro 4. When I run my code the program usually get stuck at the following line and I get a bluescreen after a while.
std::VideoCapture vidCap(1);
Strangely it doesn't always happen. Sometimes (about 1 out of 5 tries) the programm works perfectly fine and I can see my camera stream. Do you guys have ideas what I can do?
#include
#include
#include
#include
int main()
{
const char* windowName = "Webcam Stream";
cv::namedWindow(windowName, CV_WINDOW_AUTOSIZE);
cv::Mat frame;
cv::VideoCapture vidCap(1);
while (vidCap.isOpened()) {
vidCap >> frame;
cv::cvtColor(frame, frame, CV_BGR2GRAY);
cv::imshow(windowName, frame);
int k = cv::waitKey(33);
if (k == 27) {
break;
}
}
return 0;
}
