Videos won't play on Desktop
The most common cause of this problem is MIME type (i.e., Content-type) misconfigurations in your web server.
While most web servers are already configured to serve .mp4 files with the correct MIME type, they are often not configured to properly serve .webm files.
- .mp4 files should be served with the MIME type
video/mp4
- .webm files should be served with the MIME type
video/webm
