Video mixer?

[MaDoGK]

Hello hello!

A question. Would it be possible to make a video mixer from a raspberry pi? I was wondering if it was possible to connect 2 or more raspberry pi's, (if needed) a couple of monitors, (to preview the image/video before sending it to the main screen) an external HDD and any other needed hardware. I need to be able to pass through a live camera feed and videos/images through to a big screen TV or projector. No need to have sound, just video.

The hardware I recon I would have to abilities to mount, but the software I'd NEED help!

I'm looking to do it on the cheap as its for a charity organization, specifically to help the deaf community.

Any help would be appreciated,

There is no video input built in to the Raspi, so that's the first problem...

Truthfully I only need output. The camera I could connect via some kind of switch. So either the video stream from the camera or the video/image stream from the pi...

Seems like i better look for some other way to do it...
