I resolved it with this code:
$(document).ready(function() {
$("#jquery_jplayer_1").jPlayer({
ready: function(event) {
$(this).jPlayer("setMedia", {
mp3: "http://212.34.158.168:8490/stream"
});
},
swfPath: "http://jplayer.org/latest/js",
supplied: "mp3"
});
I removed oga because the type of live stream is mp3.
Hope that helps, Daniel
