I can start my video but can't play it : <p>I have this video:</p>

<pre><code>&lt;video src='videos/StressedOut.mp4' class='prize_video' controls&gt;&lt;/video&gt;
</code></pre>

<p>I've <em>checked</em>, the URL is working. <code>.prize_video</code> doesn't affect the function of the video, only the style:</p>

<pre><code>.prize_video {
  width: 800px;
  height: 480px;
  position: relative;
  left: 22px;
}
</code></pre>

<p><strong>I can click play, but the video won't start...</strong></p>
