Video Player Sometimes Not Playing

I'm developing a 2D endless arcade game for the Android where meteors come at you and you have to avoid it. The background is a video of a vortex that continuously loops, however during testing some of my players found that the video sometimes stopped playing and it would stop playing for the rest of the game. If they reopen, it might or might not work. But for other players, it's completely fine.

Does anyone know what could have possibly caused this issue? I took a look at the profiler (although I'm quite new at it) and from what I can see there are no major spikes and even if there were they seem to not be related to the video player.

Any help would be appreciated. Thanks!
