Without a link to the project to look at, it’s difficult to say, but at a quick glance it looks like the way you’re ordering your operations, including where you actually set the source seems a little off to me.

I also recognize this as the tutorial script from the Video Texture TV demo. It was originally written assuming that the video would be included in the build. There is actually a demo project that uses a Video texture from an external source here:

https://developer.playcanvas.com/en/tutorials/webxr-360-video/

You should find that the media-player script there is more robust and closer to what you’re looking for.

I hope this is helpful!
