Play YouTube playlist automatically
<p>The code under here is to get automatic the most recent video in the iframe. It returns a playlist with the most recent video as the first video.</p>

<p><code>&lt;iframe play src="http://www.youtube.com/embed/?listType=user_uploads&amp;list=UnboxTherapy"&amp; width="2000" height="1160"&gt;&lt;/iframe&gt;</code></p>

<p>Now I want to let the first video play automatically. The code to play a YouTube video automatically: </p>

<p><code>?autoplay=1&amp;cc_load_policy=1</code> </p>

<p>If you combine the 2 you get this:</p>

<p><code>&lt;iframe play src="http://www.youtube.com/embed/?listType=user_uploads&amp;list=UnboxTherapy?autoplay=1&amp;cc_load_policy=1&amp; width="2000" height="1160"&gt;&lt;/iframe&gt;</code></p>

<p>When you place the code above on your website the video will load and work properly, but the automatic play function doesn't work. It won't play automatic.</p>

<p><strong>Update after 2 years</strong></p>

<p>Now 2 years later after asking this question there is still no answer. I think it is not possible. Maybe in the future...</p>
