I'm trying to decode AAC audio stream by fromBuffer().

Help me!
//---------------------------------------------------------------------
this.ws.onmessage = function (evt) {

        buffer = new AV.Buffer(new Uint8Array(evt.data));
                asset = AV.Asset.fromBuffer(buffer);
                player = new AV.Player(asset);
                asset.start();

    }.bind(this);
