title: display video using django FileField uri [react-native]
body: <p>Hi I'm working on a react-native and I want to display a video, using expo-av, a <code>django FileField</code> uri, here's my code:</p>
  <pre><code>  &lt;Video
      source={{ uri: &quot;my/django/HE7sU4ABuNRAvwpFfW3qME.MP4&quot; }}
      onError={(e) =&gt; {
        console.log(e);
      }}
    /&gt;
  </code></pre>
  <p>Now the problem is that if I try to load a video using uri for django <code>FileField</code> video the following error occurs:</p>
  <pre><code>The server is not correctly configured. - The AVPlayerItem instance has failed with the error code -11850 and domain &quot;AVFoundationErrorDomain&quot;.
  </code></pre>
  <p>How can I configure django to allow video displaying in react-native?</p>
