Please describe your bug

After the last update it seems that ffprobe is broken and causes files to not be able to be played using DirectPlay, also it is not possible to view Media Info in the webinterface of the problemati file, it will only show the path of the file, but no media infos like video and or audio codec.

As seen in the log below the file will be shown as "Unknown codec" with ffprobe 5.0.1.

This is probably causes by the accidental release of this version as stated in this issue:
https://github.com/jellyfin/jellyfin/issues/7681

I was able to solve the issue by downgrading jellyfin-ffmpeg to version "4.4.1-4-focal".
After that Jellyfin could DirectPlay again and also correctly identified the file as "hevc".

The commands used to downgrade the version and keep the installed version:
sudo apt install jellyfin-ffmpeg=4.4.1-4-focal sudo apt-mark hold jellyfin-ffmpeg

Jellyfin Version

10.7.7
