I am having similar problem with this. The answer is in this forum ( https://groups.google.com/forum/#!msg/javacv/yD99RSl7oCI/KQIRoOIqcK4J )

try using javaCV.OpenCVFrameGrabber instead of VideoInputFrameGrabber.

Change the line 'FrameGrabber grabber = new VideoInputFrameGrabber(0); // 1 for next camera'

to 'FrameGrabber grabber = new OpenCVFrameGrabber(0); // 1 for next camera'

now it works for me everytime.

Hope it helps!
