High CPU Usage with no viewers | Tunarr | Page 1

I am on latest, but this was happening previously too.

After a channel has been watched, but now closed - CPU usage stays high. Running Top in the container shows all the usage is coming from ffmpeg.

When this happens it is consistently using 10%+ of my CPU. For comparison, this is more than qbit with 3000+ torrents actively seeding.

I notice if I restart the container (so for sure no one has used Tunarr to watch a channel) CPU usage is normal.

I started investigating this because I saw this in the Jellyfin Roku changelog and I thought it might be related: https://github.com/jellyfin/jellyfin-roku/pull/627

My stack:
-Intel N305
-Debian 12
-Jellyfin with all various device types

IIRC I've seen some clients that don't seem to properly close / disconnect the underlying request for the stream, which is the only way Tunarr knows that the connected client has disconnected

#

i'd be curious for you to try with another client and see if the underlying ffmpeg process goes away as expected, just to try and narrow where this is coming from

I really dont have anything except jellyfin clients. Is there something else I can use to access it quickly without setting up a whole new media environment?
