Overcoming camera limits: Anaglyph processors

I notice a practical limit of 3 cameras in OBS for Mac OS X 10.11. But the Mac OS itself can process at least 5 pictures. (By the way, I'm okay with 320 x 240 though would prefer it more if I can squeeze more out of it).

Doing the math, I can have 2 Stereoscopic cameras and one monoscopic (possibly Stereoscopic if the capture card allows it) game forage video.

Are there any programs outside of OBS for Mac 10.11 that can take 2 live images, and combine them in a Dubois (optimal balance between real life color and 3D depth information conveyed simultaneously) Red and Cyan Anaglyph and have the result be a "window capture" and count a left/right pair as a single video source?

I tried Bino 3d, but Bino 3D has a way of accessing USB webcams that feels "nerdy" (has to do with Unix and terminal and Linx based drivers. Understand just enough to know the smart thing is to ask for advice.)

Most of the other free Anaglyph programs only deals with pre-taped videos and not live processing, like XstereO.

If I have to pay a one time license fee to get live Anaglyph encoding, I might buy blindly, depending on the price and reviews.

Would the highest OBS for Mac OS 10.11 consider an Anaglyph combined outside OBS as one video picture for the purposes of OBS 3 picture limit?

By the way, to both save processing power on the Mac and to tap an internet source, I'm sending an HDMI preview out to my second screen: a USB plugged into an Android streaming a straight SLOBS for Android single screen capture.
