As already mentioned, each addPlayerMethod takes an (optional) CONFIG Object. This Object is used for override Rules of the Player, that are otherwise controlled by nexxOMNIA.
It is basically used like this:
var obj ={dataMode:"static",autoPlay:1};
var cfg =new_play.PlayerConfiguration(obj);
cfg.addOverride("delay",15);
var player = _play.control.addPlayer("div",1234,"video", cfg);
