Blackmagic intensity shuttle input in faceosc


I’m afraid I don’t know anything about OF, but I’m looking for a solution to use my blackmagic intensity shuttle capture device as a camera in faceosc. I tested everything with the webcam in my macbook, but can’t get the external camera working. I want to use this in a vj setup in a concert hall next thursday. Could someone help me/point me in the right direction? Thanks
