I installed xpenology on a HP Elitedesk G3 with i5 7500, 16GB of RAM. Everything works great but the Jellyfin app is having problems transcoding 4K videos. No matter of the settings used, it won't transcode more than 20 fps. I use the DS918+ image and HW transcoding is enabled(ls /dev/dri : card0 renderD128). Is there anything I'm missing? Thanks in advance!
