Description of the bug

Since recently, when I add a video file and scan the folder, Jellyfin is able to find it, name it an get every metadata, but when I try to launch the video, I get a "Playback failed due to a fatal player error.". Using vlc, I check the codec, resolution etc but they are the same as other working video files.

Reproduction steps

I don't know how to reproduce this bug.

What is the current bug behavior?

I get an error when I try to launch a recently added video, and it never did that.

What is the expected correct behavior?

Launching the video without error.

Jellyfin is unable to locate ffmpeg in your install. Did you set env var or the config to overwrite the location, and point to an invalid path?

No I didn't modify the path to FFmpeg, and I can't do it from the dashboard

That field is read-only on dashboard and if you see that field is empty it means Jellyfin does not find a valid ffmpeg

You can try what another user with similar issue did here : https://github.com/jellyfin/jellyfin/issues/12411#issuecomment-2276582704

You can also remove the encoding config file. Depends on your install, it is either

%LOCALAPPDATA%\jellyfin\config\encoding.xml

or

%ProgramData%\Jellyfin\Server\config\encoding.xml

You can just type the path into the address bar of the file manager to directly go to the folder and delete the file.

Doing so will reset the encoding config to default.
