ffmpeg.exe was unable to start - swabbie - 2023-12-01
Hello,
I've been using Jellyfin for a while now and had no problem with any of my instances in the past. So when I had my regular clean install of my PC, I tried installing Jellyfin again and this error message came up when I tried to access the server through my browser. Never had this problem before and my OS is a fresh install so I dont think I've thinkered that much to break something.
I've searched all over the forum and reddit if any similar issues occur. I thought with the recent hotfix (v10.8.13) have solved this issue since one of the changelogs mentioned ffmpeg (5019). But it turns out it still gave me the error.
I'm using:
Version: 10.8.13
Operating System: Windows 10 22H2 with no warnings and errors in the device manager
Architecture: X64
Installer: Windows Installer
Client: Edge and Floorp Browser
I've tried reinstalling Jellyfin with every data and program files deleted after uninstalling.
I've also tried analyzing the logs myself and look for specific log about FFMPEG and found this:

Is this a basic install or service install?

Its a basic install, there's also no error during the installation and was completed successfully. It is also in default install location for the app and program data

Check event viewer for any clues.
Backup the ProgramData folder for Jellyfin, uninstall, run the installer as admin.
Definitely a weird problem.
