Jellyfin GPU transcoding slower on Docker than Linux install

[toytown]

I've never ran mine outside of docker, but checking through my logs i get a 2.5second delay between FFMPEG being run and "Adding Start Event" for 2160HDR->1080pSDR. I just assumed it was buffering up the initial content (albeit your logs show otherwise). It's the same time if im on a local lan or remote.
