title: Flex: Dynamically create a preview image for a video
body: <p>I'm using the VideoDisplay to play flv's, mov's, and mp4's and everything is working great.  They are all being loaded via progressive download and are not being streamed.  What I'd like to do is to grab a single specified frame (like whatever is being shown at the 10 second mark), convert it to a bitmap and use that bitmap as the preview image for the video.  I'd like to do this at runtime so I don't have to create a preview image for every video that would be shown.  </p>
  
  <p>Any idea's on how to do this? I'd rather not fake it by playing it - seeking for that specific frame and then pausing it but I may have no other choice?</p>
