Why doesn't the video through the tag work?

Question

HTML

There is a code that starts the video:

<video src="/video/video.mp4" preload="auto" autoplay="autoplay" loop="loop" muted="" controls="controls" width="100%" height="auto" type="video/mp4"> </video>

In chrome and firefox everything works correctly, but in opera and safari it does not start. What could be?

Answer 1

The problem was in the video. Working code. Changed the video and everything worked.

Answer 2

Maybe it's a matter of compatibility?
I advise you to check the attributes and versions of browsers for compatibility
