title: Force YouTube closed captions via URL
body: <p>I want to play a YouTube video on my website, with closed captions and even translation turned on. The URL of my video (forgive the commercial nature) is:</p>
  
  <ul>
  <li><a href="https://www.youtube.com/watch?v=ygL_gJPbaKI" rel="noreferrer">https://www.youtube.com/watch?v=ygL_gJPbaKI</a></li>
  </ul>
  
  <p>I know the video is Closed Caption and Automatic Translation enabled, because I can turn both on manually when playing it.</p>
  
  <p>I have read up and tried all the URL arguments, but none seems to do the trick:</p>
  
  <ul>
  <li>&amp;hl=fr</li>
  <li>&amp;cc_lang_pref=fr</li>
  <li>&amp;cc_load_policy=1</li>
  <li>&amp;cc=1</li>
  </ul>
  
  <p>Any ideas?</p>
