Appreciate all the feedback! Reminds me of why I won't hesitate to consider OF for my next project.
Running off a Mac Mini and only average 12 fps during the more CPU intensive portions of the running app so that may be part of the problem
Right now trying to find a way to reliably duplicate the issue.
(Noob) question
If I am calling _videoGrabberInstance.initGrabber(vidWidth, vidHeight); in my setup where-how would I add the keypress code to open and close the videoGrabber?
Also, difficult question to answer without posting all my code, but if I am trying to log to an external file via ofLogToFile(), which specific methods relating to the videograbber should I be logging?
I'll keep trying to break the app manually and post any helpful info I come across.
