wansview ip camera stream capture in JavaFX

edit

I'm having trouble getting OpenCV to capture a stream from my Wansview IP Camera. I've tried to use the answer from post http://answers.opencv.org/question/79... . With no luck. I'm using the following line to open the camera:

this.capture.open("http://host:port/videostream.cgi?user=username&pwd=password");

Any tips or suggestions?
