BackgroundSubstraction example doesn't work on Mountain Lion 64bit about opencv-processing

What version of Processing are you using?

There's a problem with Capture and Video in the OpenGL-based renderers (i.e. P2D and P3D) in the release version of Processing 2.0. Specifically, the pixels array is never populated (which makes OpenCV for Processing not work since it relies on the pixels array).

If you're on a non-Retina Mac, you can try using the JAVA2D renderer instead (simply swap JAVA2D for P2D as the third argument to size()). If you're on a Retina Mac, then at the moment you have no choice but to use an older version of Processing (2.0b8 is the last one that didn't have this problem) since JAVA2D doesn't work on Retina.

Hopefully this problem will be fixed in the next version of Processing.

Alright, I remember having to deal with that pixel array problem before. Issue has been fixed 10 days ago so we just have to wait for next release: processing/processing#1852

Yeah, I mentioned it in (and that fix) in my blog post announcing OpenCV for Processing: http://urbanhonking.com/ideasfordozens/2013/07/10/announcing-opencv-for-processing/ If you don't want to wait for that release you can dive in with 2.0b8 now. It's what I've been using to develop the video examples since this issue came up.

I was just playing around with the examples. No rush :) Thanks for your great work.
