Hi all

I and a couple guys are trying to build a system from the BeagleBone Black 
that uses an IR and color camera for quadcopter video.
We have one of each of these cameras

The end goal is to be able to output a video stream of either (1) the color 
camera (2) the IR camera (3) a composite video - b/w or color, overlay or 
other.  It has to be composite video for the quadcopter. (it's a system 
already setup and we're just doing add-on)
Known problems:
The BeagleBone Black only has one USB port.  I can probably figure out how 
to make the IR camera recognizable by the system through the USB port, but 
the other two are a bit more complicated -- one is purerly analog NTSC and 
the other has a variety of digital options and a monochrome NTSC 
backup/test output.  Maybe there's a way to configure the GPIOs to handle 
this?
I'm planning on using OpenCV for the overlay/processing, though I'm not 
very familiar with it.

Sound crazy?  It is, but that's what we're doing...
