Compiling OpenCV with FireWire support on Mac OS 10.6

We have a web-camera and a FireWire camera attached and would like to get input from the second one. But when we use cvCaptureFromCAM(0) and change a number passed as an argument, we're getting data only from a web-camera.

We tried to use OpenCV Private Framework and then it works fine. So, most probably problem is caused by the fact that our OpenCV was not compiled with a support of FireWire. Could you please tell how is it possible to enable that support? Are there any additional libraries 开发者_JAVA百科needed?

What happens when you execute cvCaptureFromCAM() with -1 instead of 0?
