Best practices for Stream Media Sources on mobile devices

Hi everyone,
I have 4 movies (aprox 8 minutes long) that should be displayed on four walls in a room.
The movies should be able to be changed from outside, so I want to use the Stream Media Sources, without rebuilding.

my question is: is this possible on the oculus go or gear vr?

I had some problems when I worked on an other project with only one movie that was streamed, but sometimes the movie stayed black, because it could not be loaded correctly.

Are there any official limits about how much data the oculus go, or gear vr can stream?
It feels like it’s just a trial and error work, sometimes settings work and sometimes not :confused:
