I wanted to put a video on background for my site, for some reason the video showed up but didnt play at all, it only played sometimes randomly, I expect it to be something about the browser, I use opera gx mainly, I also tried it on edge but it only works on firefox so far, the video plays perfectly, but opera gx and other browsers are making the video not play upon site loading, probably because of how they handle media, I want to find a way to fix this and make it he able to play for all browsers.

This is html I used.
