Jellyfin FFMPEG isn't using the correct number of threads

[khatharsis]

Exactly what the title says. I have 8 cores, and I want to limit jellyfin's usage to 2 or 4 cores. However, even though jellyfin-ffmpeg *does* have the -threads 2 option in the cmdline, it's using all 8 of my cores
I've attached a screen to show I'm not saying bollocs.

Here's the full cmdline for the jellyfin-ffmpeg command, idk why it's missing spaces, but it isn't supposed to.

Code:
