The Most Pixels Ever is an open-source Java and C++ framework for spanning Processing sketches and openFrameworks applications across multiple screens. in process of moving from: http://code.google.com/p/mostpixelsever/
I was trying to get this to work, and it just wasn't running, then I discovered that the server calls server.setMessageDelimiter("\n"); on its tcp server. The ofxMPEClient() doesn't do this (so is still using "[/TCP]" I guess).
So for me, it worked if I commented out that line setting the message delimiter in the server. If I tried instead to set the client's delimiter to \n it wouldn't work either. Strange.
