[Bug]: Shared videos get scaled incorrectly

[major-mayer]

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.

Bug description

If you share a video (publically), the receiver gets a video preview/ player to directly watch it without downloading.
While this is great, the scaling on desktop could be significantly improved.
Basically, you just have to check out this link coming from a Nextcloud 29 instance running: https://nc.horbach5x.de/s/5TLH7iBWEYqFejA

What you will see is the following:

The video is soo huge, that the players controls are not visible without heavy scrolling.

Steps to reproduce

1. Share a video with horizontal dimensions
2. Open the link on a desktop device

Expected behavior

The video should be resized to fit within the browser window
