Can you set the target file for the video object in events? and is the video object on the web app using the same method for url as the other objects on the web app?, Could this be done with js if not?
From what I remember pixijs loads a sprite or video texture the same way, so the same technique should work.
Arthuroo has an extension that allows you to change the url of a resource:
My extension only works with images and audio, not videos
If we change the object type it can be used, it is for sure sub-optimal.
