I started the scan for my movie collection (roughly 140 movies) on my Raspberry Pi 3B. It has become unresponsive and I can't ssh in now. It seems to be due to all the ffmpeg instances. I have two questions:
Should I wait for an hour or should I just reboot the server? Also, is there a way to disable the setting for chapter images from the web UI? I can't find it in the setting.
I waited a long time before making this post. Within minutes of posting the system became responsive again. It only picked up on one movie though.
Jellyfin really shouldn't push the available system resources so hard. It's impossible for the user to know if the scan is actually happening when the UI and SSH interfaces have locked up. It seems it couldn't complete the scan either because it was being excessive with system resources.
Can you maybe set niceness, ioniceness and cpu affinity?
if you lower those for the type of processes that cause this, responsiveness for other things will be better.
If you can't inject things like ionice or nice into the command lines of those processes, maybe use a cronjob to find and renice or ionice -p them.
I never thought of that, good idea. This docker image spins off a lot of processes so I wonder if there’s a high-level way to instruct that for all of them.
