Hi, You can do dual video capture 640x480 30fps with Bt848 cards and I have done it over here. For info on the Bt848 driver project please see : http://www.freebsd.org/~ahasty/Bt848.html Cheers, Amancio >From The Desk Of Ajith Pasqual : > > [I'm cross posting this to -multimedia as this refers to Video Capture also] > > Hello!! > > First some background info : > > We're doing Vision Related research using a Binocular Stereo Camera called > "BiSight" (http://www.HelpMateRobotics.com/RC_components/RC_frameset.htm). > > We're planning to assemble a machine (PC) for the purpose of building an > active vision system that uses : > > 1.
