HTML5 Video playback not working with Safari (Mac and iOS)
<p>I have some videos on one of my websites. Videos are using HTML5 video tag and used best practices while rendering tags. It works just fine in Chrome, Firefox, Edge and even Internet Explorer. Except Safari! Even Facebook detect video and sharing works perfect.</p>

<p>In Safari, it detects the video, loads browser controls, but the play do not work. I don't think that its a problem with video tag, because when I open the video in new tab, it do not work either. I have tried to re-encode the video, using <code>miro video converter</code> and settings for Apple, but nothing changed. I can download the video and play it with <code>Mac Preview</code> without any problems.</p>

<p>As additional information, I am using ASP.net on IIS 7.</p>

<p>I see this error in console: <code>Failed to load resource: Plug-in handled load</code></p>
