title: MP4 HEVC video not playing with Chrome browser
body: <p>I'm hosting videos at my Wordpress website, and my users can upload mp4 video files to it. 
  I know that hosting videos is not recommended for performance, but I'm doing this for beta test for couple of months.</p>
  
  <p>Some mp4 files are not working properly, like playing only sounds with black screen. And I found out that those videos are coded with HEVC. They are playing good with Safari and IE(Edge), but not with Chrome, which is mostly used browser of my users. </p>
  
  <p>Is there any way to make my wordpress website to play HEVC videos no matter which browser user is using?</p>
