Video not playing in the executable using SteamVR Plugin and Unity Video Player component.

Hi, I am creating an VR applications which plays a video (mp4). Therefore I am using the SteamVR plugin and the unity video player component. In the unity editor everything runs fine but in the executable (build) the video will not play (it only shows the first frame). My System is Windows 7 and I am using Unity 5.6.2f1 (64bit) and SteamVR plugin for Unity - v1.2.2

I am seeing the same thing - the video plays fine in the editor, but crashes in the build. Using Unity 2018.2.9f1 and Steam VR 2.0 on Win7
