      height: '320px',
      width: '100%',
      // videoId: 'gtiriqJ_HrA',
      playerVars: {
        'autoplay': 1, 
        'rel': 0, 
        'controls': 1, 
        'fs': 1, 
        'playsinline': 1, 
        'listType': 'playlist',

        'enablejsapi': 1,
        'showinfo':0
      },

Did you ever get this to work? I could never get the ready event to fire with with an existing iFrame.
