title: How to allow video autoplay in a Google Chrome kiosk app in version 66 or later
body: <p>As of version 66 of Google Chrome onwards it will no longer automatically start playback of audio and video files when the playback volume is not muted.</p>
  
  <p>This change was made to prevent autoplay on ad videos and other annoying web page elements. However, this has negative consequences for a number of perfectly valid applications of the autoplay feature, for instance in signage applications.</p>
  
  <p>The new default behaviour of not auto playing a video with sound can be overridden at the startup of the Google Chrome browser with the command line options</p>
  
  <p><code>--autoplay-policy=no-user-gesture-required
  </code></p>
  
  <p>or</p>
  
  <p><code>--no-user-gesture-required
  </code></p>
  
  <p>The new default autoplay behaviour is also present in the Chrome browser on ChromeOS (currently in the beta channel). For Kiosk-apps running on ChromeOS there are no command line options, only configuration using the Manifest.json file.</p>
  
  <p>Currently there is no option in the documentation of the Manifest.json format that allows changing the autoplay policy. </p>
  
  <p>Is there any way to change the new Chrome default autoplay policy in Kiosk apps to allow autoplay of videos in an app on ChromeOS?</p>
