title: Video stored in Firebase not playing in Iphones
body: <p>I have a 5 Mb .mp4 video in firebase storage, using the below code it loads well in all web browsers. However it does not load in iPhone. .mp4s didn't work in safari but .mov did. However both .mp4 and .mov do not work on an iPhone. What can I do or video format to use?</p>
  <pre><code>&lt;video width='100%' height='315' poster='{{ value.image }}' controls loop muted playsinline&gt;
       &lt;source type='video/mp4' src='{{ value.video }}'&gt;
  &lt;/video&gt;
  </code></pre>
