Hi, I'm running Jellyfin (tried both 10.6.4 and 10.7) in a container on my DS918+ and am trying to use VAAPI transcoding to transcode from 4K to 1080p when not at home (Yes I know we're all at home all the time at the moment but I'm planning ahead).
Has anyone got this working?
I've got the built in ffmpeg to recognise the device /dev/dri/renderD128 and claims to be using it but I'm still not getting above 10-15 fps.
The transcode folder is on an SSD (but the file itself resides on an HDD)
Plex appears to be able to transcode the file fast enough but I don't want to use Plex or get a Plex pass.
My docker compose is attached.
