synching video camera recording with vizard

Hi,

We are running an experiment in which we need a video recording of a real person in real life wearing the HMD as they participate in our VR experiment. We need to time lock the video to some kind of event in Vizard. How do we do this?

This post...

http://forum.worldviz.com/showthread...t=video+camera

....sort of suggests such automatic time-locking is impossible, but I find that hard to believe.

There is a vizard documentation page about "Generic Capture Devices". Is that appropriate? I might do something like this....

#Create Video Camera extension
video = viz.add('VideoCamera.dle')

#Connect to next available generic video capture device
cam = video.addWebcam()

....but then how to I save the stream of video data from the video camera to a file?

Thanks,

Bill
