Doesn't play videos on external access in browser

[Paiper]

Those are ffmpeg logs.  And they look fine.

Actually the user that does not get the videos does not produce ffmpeg logs. So the problem is before the ffmpeg starts. IMO.

For what you are asking for, sharing a link that anyone can just play, that is not possible unless the remote user pasting the link in MPV or VLC or <insert video player>.  It will never work in the browser since the link is just a download link.  Jellyfin does not allow access to the web player without authentication.

Understood.
My usecase is to share videos within the family. So a user account with password would be fine but it has to work which it does not currently. The content is only family  vids. So no stuff with copyrights on. But I prefer to have my videos on my server and not on an open platform in the net. 

I think I will create more users for testing. (hopefully one will work)

Thank you for all your effort.
