Software search: Video while pressig a button / with shuffle function

[lifeisfiction]

Hi, I'm new

need very urgent an application for an installation... don't know where to start, so hope you can help me.

TECHNICAL IDEA:

There's a big LCD-Screen with a basic video loop. Infront there's a remote hanging from the ceiling. On the remote there is just one button. If you press it, there should be a shuffle mode that select one of 8 videos and play. But it shall only play until the button is released. If you release and press again, there shall be another clip, played from the beginning.

WHAT I HAVE: computers, Win + Linux, an Arduino board & a button.. but no experience with, the screen .....

What comes in your mind? Wanted to program something with Processing and the Arduino board, but the exhib is too close, and my skills are too bad...
Would be glad if you know something that fits, even whithout the basic loop.

a button release is an event. map that event to play a black video.
a button press is an event, map that to play a random clip.
