Using Video Player with URL in WebGL

Has anyone had success with loading in multiple videos via url into the video player component and then building to WebGL? I'm building an experience where multiple videos need to load within one scene and can be viewed by the player in any order. In my experience, this basically works in the editor but the load times seem impractically long in the built WebGL app, and there does not seem to be a way to ensure that all the videos will load when the player needs to view them.
