What steps will reproduce the problem?
1. Simply run Test2.java on the javacv home page.

I am expecting a frame with a webcam(attached to my PC) image generated.
It returns an error below :

This only means that OpenCV does not support your camera. You will have to try 
other things like different versions of OpenCV, FFmpeg, etc. This is not a 
problem with JavaCV.
