Hey,
This error is getting generated because your webcam is not able to read your image or video from your camera.
So, you need to change the interger value in the VideoCapture() function.

Although the link that I am pasting is realted to different error but this will surely help you. Try it out and if then also your problem isn't resolved then I am here for you to help.
