I just started switching my new website to ReadMe but encountered some trouble with my WebM animations. On http://chrisoffner.eu/four-bouncy-balls/ I embedded a WebM file using: [video width="1920" height="1080" webm="http://chrisoffner.eu/wp-content/uploads/2015/06/bouncingballs_01.webm"][/video]
It played back perfectly fine using TwentyFifteen but now in ReadMe I only get a dark gray rectangle and a “Download File” link. How can I enable WebM videos on my site?
On Firefox it loads the video but on Chrome it doesn’t.
