title: YouTube API: How to specify an API callback after an uploaded video has finished encoding?
body: <p>I am uploading videos using the YouTube/Gdata API (in python).</p>
  
  <p>After a video has been uploaded via the API, I receive the a response with data about the video (Youtube link, id, etc). However, the video is not publicly available while it is being encoded by YouTube (typically a few minutes).</p>
  
  <p><strong>Can I specify a callback url that YouTube can post to after it finishes processing the video?</strong></p>
