Safari not uploading html5 video component.

Hi,
So basically my problem is connected with the safari browser as not being able to play uploaded video, as the problem is only connected with the specific browser, chrome, mozilla and edge, do the work. I searched for related topics, but adding attributes as “playsinline” didn’t help at all, and finally I was able to find something similar to my problem, I guess so, it was about adding response header ("Accept-Ranges:bytes), but no idea how to do it. Any chance helping me ?
