Marvin Project plugins for webcam: No image is loaded from webcam

Question

I'm trying to run the example provided at the MarvinProject website:

http://marvinproject.sourceforge.net/en/examples/videoFilters.html

that one, but I can't make it work, I'm using an HP pavilion dv7 laptop. I already installed the javacv libraries.

My questions are: why am I getting this exception? why can't I see anything in my frame window?

Thanks very much in advance!

edit: I forgot to include this... The exception is thrown at this line of code: imageIn = videoInterface.getFrame(); it's inside the run() method. Thanks!

EDIT 2: I just figured out what was the problem!

I just needed to load a couple more libraries! the CPP ones!

https://code.google.com/p/javacv/downloads/detail?name=javacv-0.6-cppjars.zip

those! Thanks everyone anyways! Cheers.

P.D.: I still can't answer my own question due to being a newbie and not having enough reputation, that's why I'm editing, I have to wait 7 hours or so, I will be posting this as an answer soon! Cheers!
