Hello,

Thanks for the answers. I've been looking around and it doesn't look like that omxplayer accepts OSC messages. Does it?

Also how are the Pis connected to a network? Through ethernet? In this case I would need a router with 20 outputs right?

To explain a bit more about the project. It's a live band, with precomposed videos playing back (with stop/start variations) across a bunch of analogue TVs placed on stage, all in sync with the sound. We don't know yet to what extent the result will be predetermined or generative but as long as there is the possibility of controlling the overall visual rhythm... The live sound from each instrument is also being transformed through lots of DSP in pd. So it's a complex setup and it needs to be reliable as we'll be taking the show on the road at some point.

Many Thanks

yes, but Gem won't work. That means you will have to drive something
like omxplayer from pd.

That also means you can't do generative video with pd/gem.

I still think you can get better results with pre-owned pentium 3/4 than
with the Pi, for a fraction of the cost (starting at 15USD on ebay,
desktop or laptop).

yes.

maybe it's time to elaborate on your needs : you want to play 20 movies
(soundtrack included), or to have 20 drawing surfaces that you fill with
Gem ? How is sound linked to display ?
