video player works in editor but not in build

Hello, i’m trying to play an mp4 using unity, i’m using the code provided here :

it works in the editor. but when i try to build it to any of my 3 devices (samsung galaxy, windows os, or oculus go), the video does not work. on my samsung the screen stays black for the duration of the movie, and on windows/oculus go the video just doesn’t play and the starting scene is all i can see.

anyone know what could cause this to happen? i’ve tried different encodings, and different video formats (mp4).

if i can’t get this working, does anyone know a better way to display videos? maybe just load the raw data and play it on textures as a sequence? there’s no sound.

Did you find out? I have same issue
