Videos won't playback on IOS device

Can't seem to get converted videos to playback on cumulus mobile. They work fine on the desktop on my PC but all i get is a thumbnail and no playback on mobile.

I have tried altering the ffmpeg script in the admin panel for mobile encoding but still no luck.

I am running cumulus on an Ubuntu 16.04 server.

Any help would be appreciated.
