The title might be too long, but I can't seem to figure this out. I have tried the published inputs/outputs for various other things to get my setup working. it's done a good job for playing simultaneous video on two computers in perfect sync. However I need some form of interactive control once I get the system running so I can tweak some parameters.
namely, the idea is to use the quad warping GLSL shader to virtually keystone my video stream per computer-projector-combo. I figure this woill be easy enough by holding down 1-2-3-4-5-6-7-8 (where 1-4 is the four corners of projector 1, and 5-8 are the four corners of projector 2). Then, by moving the mouse, I can tweak that value until we get a perfect match with the 3D surface. All I'm asking is for the simplest of mouse feedback from a fullscreen QCV processing/renderer file pair. Please don't respond without trying it first because I've read replies to this before and people seem to think it works like everything else "just publish the outputs" and it doesn't.
