Reasoning or why should it be changed/implemented?

Environment data

iOS version: iOS 18.1.1

Nextcloud iOS app version: 6.2.1.0

Server operating system: Debian 10 Linux 64bit

Web server: Nginx

Database: pgsql

PHP version: 8.3.9

Nextcloud version: 30.0.4

Start by reproducing video playback in the iOS app and inspect the request to the remote.php direct-download entry point. Review the reported apps/dav/lib/Direct/Server.php path and the server response, then compare behavior with the VLC error. Done means supported video files play in the iOS app without the reported error.
