title: How to take screenshots of a Flex Spark VideoDisplay?
body: <p>I want to build a component, where the user can play a video in a Flex Spark VideoDisplay. There will be a button and whenever the button is pressed, I want to save the current time of the VideoDisplay plus a screenshot. The screenshot needs to be someway saved, because I want to display all times and screenshots in a DataGrid (screenshots should appear when the user hovers a time in the DataGrid).</p>
  
  <p>So, how can I take screenshots of the Spark VideoDisplay and save/display them?</p>
