Additional context

To narrow the issue down to MacOs, I run nix-shell -p jellyfin-media-player in the nix docker container. It worked.

Hi,
thanks for the issue.
This seems to be caused by build errors with qtwebengine, maybe it was fixed by: #383990 ?

could you check this by running nix shell nixpkgs/master#jellyfin-media-player ?

[nagyv]

Checked nix shell nixpkgs/master#jellyfin-media-player runs to completion without errors:

nagyv@MacBookPro:~/ > nix shell nixpkgs/master#jellyfin-media-player
nagyv@MacBookPro:~/ > echo $?
0

I think, we can close the issue.

[paumr]

Perfect, thanks for checking!
