You have a few options.
Either do 'eye deocomposition', i.e. render left eye and right eye on
different pipes then readback the framebuffers using glReadPixels and draw
using glDrawPixels to left and right buffer on a composition pipe. I.e.
your final pipe outputs an actual active stereo video signal.
Or you can probably find an electronics box (I can ask people I know in
the video business) which turns two mono signals into a single stereo
signal.
Had it been the other way around, i.e. active stereo to two eye channels
out then theres is a simple trick you can do with special vfo's without
touching the application. However it doesnt work the other way around.
