A different video file for mobile

Hi, first of all, thanks for a great plugin. I just wonder if I can set up a different video file for mobile devices, like landscape for desktop and portrait for mobile?

I tried to hack it with a custom javascript (https://stackoverflow.com/questions/76142819/loading-different-videos-based-on-mobile-or-desktop) but it does not work. I still see the original video file on mobile.

Thanks for your help!
