title: How do I get GPU acceleration for H264 in an Adobe Air fullscreen app?
body: <p>I'm toying with an Adobe Air app that plays quite large movies. I want to run it on a 1920x1080 display connected to a Mac. Unfortunately, the movies tend to stutter and I'm betting that happens because I'm not using HW GPU acceleration for H264 playback.</p>
  
  <p>Most of the player code is ported (aka copied) from a web player I built and which runs very smooth on the Flash Player from the browser. So the code shouldn't be the problem.</p>
  
  <p>In the Flash Player, to use GPU acceleration in a fullscreen mode, you have to set the <code>Stage.fullscreenSourceRect</code> property. However, this doesn't seem to work in Adobe Air...</p>
  
  <p>Anyone got any ideas?</p>
