Jellyfin Startup Instances (33 of them)(conhost.exe?)

[NJ Route22]

using 10.10.7. Everything seems to be working normally.

However, when I checked the server (my pc) - it shows a high number of startup instances located under Jellyfin.Windows.Tray.exe (33)

Conhost and FFmpeg command-line tools make up most of the entries. I thought it may have had correlation to real-time monitoring of my libraries - but the number did not change if I disabled real-time monitoring.

So - why so many FFmpeg and conhost entries when launched? Is this normal? (I'm using windows 11 if that helps)

See screenshot

Thanks!

Upon further inspection - it seems like it's running multiple instances because conhost.exe cannot be loaded due to some kind of syntax error in the file location? Is that a bug in Jellyfin server for windows 10.10.7?

Or am I out of my league here?

See screenshot of the error.

Can you share your jellyfin log via privatebin.net?

I can do that. Is there a way I can edit the log file to only include relevant startup info and delete things that are not necessary for the troubleshooting?

[TheDreadPirate]

If I knew that I would know what the problem is. But the goal is to get as much info as possible about the state of jellyfin, which is unknown. Startup logs can be helpful, but how it is behaving post-startup is also important.

Okay -
Here is a log from the day I noticed it starting up with all those instances.

I don't see any issue. Likely library scan related ffmpeg usage. AFAIK, that is the only kind of activity that would spawn that many ffmpeg processes/threads. Connhost is the Windows service that allows apps that normally spawn a command prompt to do so "invisibly". As in it doesn't spawn a million pop ups while you're using your computer.

Thanks - like I said, Jellyfin is working. I just didn't know why it had so many in the actual startup. When I right-click the Conhost.exe entry, it gave that "file not found" message - which to me seems like it was being requested with a typo of some kind - causing a loop?

I do not know how this program works upon startup which is why I came to the forums to ask.

What does your Jellyfin app look like in the startup of Windows (if you're using windows and not some other platform)?

I am on Linux.

I'm wondering if these lines are spawning ffmpeg processes.

Code:

[2025-04-07 18:09:51.922 -04:00] [INF] [27] Emby.Server.Implementations.MediaEncoder.EncodingManager: Skipping chapter image extraction.....

I'm assuming it would start a ffmpeg process based on the class that is generating the log. These lines would appear every time a library scan is run. Which usually also includes startup.

I think those are for short episodes (5 min or less) - like bugs bunny or Peppa Pig. Not sure why they run every time. I have chapter image extraction off anyway.
