[PD] combining 2 or more cameras to output 1 stream in Linux

I don't see how you could make the result available as a v4l device 
without doing things in C, and even then I would not know how to make it 
work.

Certainly not possible directly in PD without making your own v4l output 
external. I guess there is no such thing? (vloopback?)
