title: Creating FLVPlayback in AS3 not working
body: <p>If I create a <code>FLVPlayback</code> using <code>ActionScript3</code> I can't get output, but if I drag on a FLVPlayback 2.5 component and set the source it works.</p>
  
  <pre><code>import fl.controls.Slider;
  import fl.events.SliderEvent;
  import fl.video.FLVPlayback;
  
  var slider:Slider = new Slider();
  slider.minimum = 0.0;
  slider.maximum = 1.0;
  slider.value = 1.0;
  slider.tickInterval = 0.1;
  slider.snapInterval = 0.01;
  slider.liveDragging = true;
  slider.addEventListener(SliderEvent.CHANGE, slider_change);
  slider.move(120, 20);
  addChild(slider);
  
  var flvPlayback:FLVPlayback = new FLVPlayback();
  flvPlayback.autoPlay = true;
  flvPlayback.source = "rtmp://xx.xx.xx.xx/test/abc";
  flvPlayback.x = 10;
  flvPlayback.y = 40;
  flvPlayback.isLive = true;
  addChild(flvPlayback);
  
  function slider_change(evt:SliderEvent):void {
      flvPlayback.volume = evt.value;
  }
  </code></pre>
