webcam access using opencv with processing in an applet or application

Question

I made a small sketch with processing using opencv to face detect and track. But when I export as an application and start it nothing happens, same as an applet. First I exported the applet and thought this must be a security issue, and struggled with some hack for processing to sign your java applet.

With no luck I thought I would atleast be able to run it as an application but no success.

Anyone know what to do?

If you're on OSX 10.6 there is a known bug with the quicktime camera stuff not working in 64-bit mode. Make sure both your install of processing and the exported application are set to run in 32-bit mode.

Right click -> get info -> Open in 32-bit mode
