Hello. I am using the VideoBlob patch from the Jitter recipe Book 1 (http://cycling74.com/2006/02/06/jitter-recipes-book-1/) but want to use a live video feed rather than a quicktime movie. In my mind all I need to do is change "jit.qt.movie" to "jit.qt.grab" and "read" to "open." This, however, does not work. Has anyone worked with this specific patch and know what else needs to be changed?
