> Pentium-IV systems (Dell Precision Workstation 530 to be precise) and
> 1394 cameras.  Details of the hardware configuration are on the website

> Right now we're fighting an issue between increased capture quality and

> with WDM drivers, but VIC crashes whenever we attempt to use them as a
> capture source.
> If you want to take a route more VIC compatible, you can use Osprey
> capture cards in these systems.  We demonstrated two Osprey-500 boards
> capturing 320x240 and 640x480.  Unfortunately, we also found out that
> Windows VIC crashes when attempting to transmit 640x480 and we were
> unable to get two instances to transmit dual streams.
> Currently we're working on a VIC replacement for video capture and
> receive due to the issues we've found above based around a DirectShow
> architecture with RTP transmission.  The advantage is we can work around
> the issues we've uncovered.  The disadvantage is we won't be using h.261
> and therefore won't be compatible with existing VIC based video
> capture/display systems.  We'd love to find an existing video system
> that is VIC compatible and works around the issues above, but we haven't
> found one.  We're talking about possibly funding an RFP to create just
> such a beast, but it's still just talk.
