Hi, I also got the exact same error on a new install (Windows 10, Julia 1.5.2). Turned out my system was a Windows N version (without video codecs installed by default).  
Installing [the media feature pack](https://support.microsoft.com/en-us/help/3145500/media-feature-pack-list-for-windows-n-editions) solved the issue.  
It might be helpful to put a warning in the Readme if this can be reproduced.
