Comment 2 Thomas Andrews 2023-02-09 19:32:15 CET

Tested in a mga8-64 Plasma guest in VirtualBox.

I installed mediainfo-gui-qt, which drew in lib64zen0 as a dependency. Ran mediainfo, and checked the information of several different media files.

Updated lib64zen0, and repeated the test, receiving the same results.

Looks OK here. Validating. Advisory in comment 1.
