Live feed display

Yo. Anyone have any experience with video feeds?

I have a live feed set up on my machine coming through a Videum capture card. Everything works fine and I can see the feed in the videum configuration tool. What I’m after is some software (free or otherwise) that will let me display this feed full screen with the ability to pause. Other options would be a bonus but I’m struggling to find anything at all. I think I’m searching for the wrong terms as all I can find is screen capture stuff or software designed to record the feed, not actually display it as it arrives.

Anyone who points me in the right direction wins a lolly.
