USB-Cameras about ssl-vision HOT 8 CLOSED

Changed Issue type from "Defect" to "Enhancement".

Since ssl-vision is used primarily for the RoboCup SSL, and since the cameras 
for the competitions are firewire, this is not top priority. However, USB 
support might be extremely useful for other domains than SSL, and any work 
towards achieving this goal would be greatly appreciated.

I have added Video4Linux2 support to ssl-vision so it can be used with USB 
cameras and other non-Firewire devices.
My branch with this support is located at:
https://github.com/cktben/ssl-vision

I have tested this with the Playstation 3 Eye, which is cheap and capable of 
640x480 at 60FPS.  The camera can be mostly configured inside ssl-vision, but 
there is currently no option to set resolution or framerate.

Ben, this is great. I started to test your Video4Linux2 support so we can 
incorporate to the official version. We most likely will do it after RoboCup 
2013 so there's enough test and to avoid making changes too close to the 
competition date.

when i wanna cmake the project this errors apeared :

-- Looking for Q_WS_X11
-- Looking for Q_WS_X11 - found

-- Looking for Q_WS_WIN - not found.
-- Looking for Q_WS_QWS

I had the same error, but only in debug mode.
Everything is fine when building in release mode.

PS: we have forked the code to use OpenCV as the capturer, the code is here:
