I can capture from a single usb camera at a time, but not more than one at once.
I'm using a recent build of the git trunk (so, 3.0-ish) and running os x lion. I realize I could try other versions of OpenCV.
Has anyone ever gotten multiple usb cameras working on a mac?
Thanks! Tyler
Are you using C, C++ or python? If you're using C++ u need start the VideoCapture(), VideoCapture(0) for webcam pattern, 1 for secondary and so on. And then initialize the frames.
I'm using c++ and grabbing from each camera in a separate thread (trying to). Have you gotten multiple cameras working on a Mac? I know how the API should work -- the problem is that it's not working. I can capture from one camera, but not more than one at the same time.

I think, that this is exactly what you need. Keep reading, it has guidelines on how to enable multiple camera reads :) Another approach could be to open up two threads and address a cam port on each thread!
Thanks, StevenPuttemans. The link you suggest says that OpenCV cannot do more than one camera at a time (at least for the PS Eye).
Yeah but it does state how to solve the problem or how to work around it. Like I said, keep on reading!
