title: Capturing bitmapData from a video display playing a h.264 (mp4) video
body: <p>I have a video file which I play in an Android air app. I'm trying to capture a frame using <code>bitmapData.Draw(video)</code>, but it works only for .flv video.</p>
  
  <p>The videos are played locally - no internet or server.</p>
  
  <p>Once I change the video to an .mp4, it plays it on stage, but has a blank bitmapData after the draw function is called. I doesn't say any error.</p>
  
  <p>How can I capture a frame from the played .mp4 video?</p>
  
  <p>Note - 
  It's a Video component, not a <code>StageVideo</code>, since I know it's impossible with <code>StageVideo</code>.</p>
  
  <p>The net stream initialization. I also added the <code>checkPolicyFile = true</code> - it didn't help.</p>
  
  <pre><code>my_nc.connect(null);
  my_nc.client = this;
  
  _ns = new NetStream(my_nc);
  _ns.client = this;
  _ns.useHardwareDecoder = true;
  _ns.checkPolicyFile = true;
  </code></pre>
