Issues playing on Android on some video files

Hi,

I am running Plex server Version 0.9.16.6 on Windows 7 and have been experiencing some videos that do not play over the Android TV app (Running on Amazon Fire TV) as well as Android mobile app.

I just get the error saying something like the video cannot be played and that I should restart both server and device (which I have done multiple times). It only seems to be some video files.

Please see the log attached.
