title: How to add Subtitles to Youtube video using Youtube API?
body: <p>Is it possible to <strong>add subtitles</strong> to <code>Youtube</code> video using <code>Google Youtube API v3</code> (important condition - for video's not owner)?</p>
  
  <p>Task: add custom subtitles in selected language using the <code>Google APIs Client Library for JavaScript</code>.</p>
  
  <p>(<code>Google maps API</code> allows add, custom <code>Markers</code> (for example) to their maps, maybe there is a solution for <code>subtitles</code> when we're talking about <code>Youtube API</code>?)</p>
