function goFullScreen() {
Stage[“displayState”] = “fullScreen”;
flvplayer._width = 600;
flvplayer._height = 450;
flvplayer._x = 0;
flvplayer._y = 0;
//------------------------------
_root.fullState = 1;
play();
}
function exitFullScreen() {
Stage[“displayState”] = “normal”;
flvplayer._width = 400;
flvplayer._height = 300;
flvplayer._x = 19.2;
flvplayer._y = 57.1;
//------------------------------

_root.fullState = 0;
