user1556: I was wondering if there was any software that can process video on the go. For example I need to merge few video inputs (see image) and then pass the processed video to software that streams video live.

Is this really possible?

user456: I have seen similar things built with vvvv. I believe the current equivalent for Mac is Processing.

user1303: I have used a freeware software program "VH Multi Camera Studio" to do something similar to what you describe. While it is still possible to find and download that program (just Google the name), it seems the developer no longer supports it.
The modern incarnation of the company exists as http://www.splitmedialabs.com/ but I have no experience with it in its new form.
