Video not playing on iOS10 Chrome
<p>I just can't seem to locate what's wrong with this video snippet.</p>

<pre><code>&lt;video poster="sample.jpg" loop autoplay controls muted playsinline&gt;
    &lt;source type="video/webm" src="sample.webm"&gt;&lt;/source&gt;
    &lt;source type="video/mp4" src="sample.mp4"&gt;&lt;/source&gt;
&lt;/video&gt;
</code></pre>

<p>The video plays without any problems in Safari (haven't tested against earlier versions of iOS, but my only concern there is the autoplay issue?), but on Chrome the only thing I see is the cover image and a play button that doesn't trigger anything. Am I missing something? Do I really need to use JS to get it to work?</p>

<p>Update: It seems there's an issue with playing Webm files with iOS Chrome - I've tried several files from different locations and they seem to be needed to be downloaded first before being able to play.</p>
