Playing a video stream problem

I am trying to play a video stream, I followed the instructions below, when I play level on PC, I get audio, but no picture. I included a link to simple project if you need to download it…I get a white screen, no video at all, but I do hear the audio. What am I doing wrong?

[Instructions][1]
[1]: Play a Video Stream | Unreal Engine Documentation
