I have a Synology DS1823xs+ with a NVIDIA T400 4GB GPU (pretty common setup, I’d say) running version 1.42.2.10102 and I just realized the GPU is no longer listed as an option in the ‘Hardware transcoding device’ dropdown - therefore hardware transcoding is no longer working/possible. (Needless to say, this wasn’t a problem up to this point)
We have reached out to Synology. They made it perfectly clear: “No Support of such a configuration.” Therefore this is not something that we/Plex can support.
External GPU support in a DS1823xs+ is NOT SUPPORTED
Well, it seems I overlooked the oldest (IT) trick in the book. After turning off the Plex service and turning it back on again, the video card is present/used again, so this might have been just a “hiccup”
