    Hey all,
    I've recently installed jellyfin with docker on a new mini PC (previously used a synology DS220+), and managed to get transcoding working well. I noticed though during testing that transcoding is actually using about 5% more CPU on average with QSV than with VAAPI (transcoding HEVC 1080p), which I feel like should be the inverse, from what I've read.

    This issue isn't urgent to me because most of my users are using native TV apps and therefore directplay, but it seems odd and makes me think I might have something misconfigured.

    I'm running linux mint, docker, and this is the PC in question: https://www.amazon.ca/dp/B09MFKZFYG

    I've attached two logs, one QSV and one VAAPI.

    (edit: It's occurred to me that I accidentally posted this in General Questions instead of Troubleshooting, please move it for me if you're so inclined)
