Server: Video Link Share Page not Fitting to Screen

[Engineer-of-Stuff]

Steps to reproduce

1. Upload a video (for me it was a 1920x800 video, the Han Solo movie).
2. Share the link and visit it.
3. Play the video in full screen.
4. See how it does not fit to screen.

Expected behaviour

Video fits to screen.

Actual behaviour

It does not fit to screen.

---

Also, video does not play on Chrome, but that's not the problem here (it does work fine in the logged in view or in Firefox).
Console errors:

The video could not be loaded, either because the server or network failed or because the format is not supported.
Failed to load because no supported source was found.

I've looked around and found nothing.

[MorrisJobke]

We don't do much except giving the browser the resource and say "it's a video in this encoding" and then all the rendering and decoding is done by the browser. Unfortunately we can't do much on our side. Sorry for the bad new.

[TheManchineel]

I still have this very same issue

then can't you advise which explorer or what plugin or doing what we can adopt to avoid this issue --can't fitting to screen??
