Ah, my use case right now is almost exclusively streaming stuff from my laptop to a phone with HEVC support over a local network so I can just turn transcoding off and be okay.

I did however have issues with my lack of transcoding (I turned it off myself, not Jellyfin’s fault. Pitchforks down, people) on a tablet without hardware HEVC support though so I may have to experiment with it soon.

FWIW I had to go in and turn the feature off but there’s also a good chance it was using CPU instead of GPU
