Wont playback lots of mkv files after 10.9

[isvein]

Describe the bug
Not sure if it started on 10.9.0, but after 10.9.x jellyfin for ios just wont play a lot of my bd/dvd rips in mkv container. Not everything wont work, have more luck with dvd than bluray and home videos in mp4 container works.

The player just spins and ether the app crashes or nothing happens.

The same files work fine on jellyfin web (from pc), jellyfin for Windows and on swiftfin so I know its not the files.

System (please complete the following information):

• iOS Version: 17.5.1
• Jellyfin Expo version: 43.0.0
• Jellyfin Server version: 10.9.7
