Snooping of an existing 1394 camera

[Robert Degenford]

Good Afternoon,
	We are supporting an older (about 5 years old) IR camera system  
manufactured by cincinnati electronics.  It has a pixel link 1394  
interface.  On a hunch, I downloaded the Industrial Camera driver,  
and it worked!  Using the "evocam" application  on a macosx 10.4.9  
powerpc platform, I was able to view the live IR coming across the  
firewire.  When I selected the source of the video (under  
preferences), I could see the "vitana 1394 CEIR" as the driver.   The  
problem we are having is that we are trying to share the 1394 camera  
between two computers.  The first one is the original legacy PC  
system.  With our Mac we are essentially trying to "snoop" the 1394  
signal coming from the camera and process the data independently.   
Unfortunately, each application on each system seems to "lock" the  
1394 camera and prevent the other system from accessing the camera's  
data.  I have written my own grabber using the quicktime sequence  
grabber, and it does the same thing.  I noticed the original PC API  
(written by Vitana) has a "snoop" mode, where by it queries the  
camera for the channel is and snoops the data.  Do you know if there  
is a way to do this in quicktime?
Thanks!
Any help you could lend on this would greatly be appreciated!
