Video Capture Source in QuickTime – Elgato Video/Game Capture

Hi all,

Is it possible to use a Elgato Video/Game Capture as a Video Capture Source in QuickTime and/or make the source available system wide, just like a USB webcam? For my purpose, the included Elgato Software is not sufficient.

I'm trying to figure out if I can get a live stream from a camera to my Mac (not the Internet!) that is connected via Cinch (Yellow, Red, White) and basically mimic the functionality of a USB Webcam, so that the camera can be used in QuickTime, Photo Booth, Final Cut, etc. If there are other devices other than Elgato's that support such functionality, please let me know.

Thanks in advance.
