Jellyfin YNH 1.10 server won't start after install on YunoHost 12 because of FFMPEG

[GGGQO]

Hi, I recently deinstalled Jellyfin 10.9 from my YunoHost 11, updated Yunohost to version 12, and then reinstalled Jellyfin 10.10. Jellyfin 10.10 installation went smoothly, no problem occured. But it appears that I am unable to log into the Jellyfin server. Choosing the server on the jellyfin landing page shows a message like "unable to connect to server, verify that it is operational and retry" "Nous sommes dans l'impossibilité de nous connecter au serveur sélectionné. Veuillez vérifier qu'il est opérationnel et réessayez." Checking the log gives more info, I have a FATAL error preventing the server to startup correctly, pointing of FFMPEG :

Useful errors : [2024-11-17 14:46:52.188 +01:00] [ERR] Error validating encoder System.ComponentModel.Win32Exception (2): An error occurred trying to start process ‘/usr/lib/jellyfin-ffmpeg/ffmpeg’ with working directory ‘/var/lib/jellyfin’.

I have seen mentions of FFMPEG changes in the recent commits for 10.10 version, maybe there is something more to address on this. Thanks

What are the outputs of the following commands?

which ffmpeg
/usr/lib/jellyfin-ffmpeg/ffmpeg

Can you share your last Jellyfin upgrade log?

Hi,

root@noself:~# which ffmpeg
/usr/bin/ffmpeg

The ffmpeg that shows in your example command is in its location :

root@noself:/usr/lib/jellyfin-ffmpeg# ls
ffmpeg  ffprobe  lib  share  vainfo

but there this another one in '/usr/bin/ffmpeg' that is referenced and must get called instead of the right one.

I did not do an update, I removed 10.9 and then installed 10.10, does that change anything ? can you tell me where that upgrade log is located ?

I found the jellyfin 10.10 install log instead : https://paste.yunohost.org/avijuqinay.apache

Jellyfin 10.10 Install yml file : https://paste.yunohost.org/ekafedajec.yaml

10.9 Remove log : https://paste.yunohost.org/ecirawodik.apache

10.9 Remove yml : https://paste.yunohost.org/poyohayafe.yaml
