title: Is there a way to get fine grained progress of Elastic Transcoder job?
body: <p>I'm using <code>read_job()</code> API to monitor jobs' progress. This only gives me a very coarse info about the status being one of the: <code>Submitted | In Progress | Complete | Canceled | Error</code>. </p>
  
  <p>However, I'd like to show the user a percentage or ETA when in the <code>In Progress</code> state. Is there any API which gives such a fine grained progress information?</p>
