Hi, I also invested a lot of time in finding how to do this.
It should be a matter of passing the correct options, in either of these ways.
The options are the same as when you would use them in command line.
But I didn't succeed in seeing the visualizations.
So according to me it is not possible.
//var options = new Array("--audio-visual=visual","--effect-list=vuMeter");
var options = "--audio-visual=visual --effect-list=vuMeter";
var itemId = vlc.playlist.add("
http://yp.shoutcast.com/sbin/tunein-sta ... s?id=69637", null, options);
vlc.playlist.playItem(itemId);
vlc.audio.mute = true;
