hey pd brains!

im really in super need of some advice.

i want to use a raspberry pi with a beamer to project a video that is manipulated by a touch sensor. Is it possible to use PD in that sense?

I can only find examples of audio influencing video, and in my case there wont be any audio at all..

I would be extremely gratefull for your help

Maybe the [gpio] external would help? But I think that's in Pd-L2Ork, not Pure Data. Still you might find that useful.
I think some people use VLC to play videos on the Pi, and use Pd to launch scripts (probably via [shell]) to control VLC. Not sure how, never tried it.
