Hey guys, when I use the video input patch in quartz composer I don't get a feed from the iSight. Sometimes I the green light on the camera turns on but I don't get the video in the viewer. Yes the camera works in other programs. Any idea what the problem may be? I am the guy that made the "invisible" & "ipod person" iChat effects but when I made them I just used pictures to test them I would like to do it with live video. If you have any idea how to fix this let me know, I really appreciate it.
