I'm having a problem with Processing 2.0 beta (3 to 5). I'm trying to use the Capture object from processing.video.* and it doesn't work if I have P2D, P3D or OPENGL in the size. I also found that GSCapture also doesn't work in Processing 2.0b with this parameter.
To avoid conflicts I tried the "GettingStartedCapture" sketch. It just hangs on the startup.
