Transcoding help for Synology DS418+ worker

[paytah232]

Hi, I'm having some trouble trying to access the Intel Quick Sync functionality from a Synology NAS with a worker deployed. I believe all the configuration is correct, as if I remove FFMPEG_HWACCEL, the transcoding works, but obviously, isn't hw transcoding. When I enable it, I get the following issue:

plex_worker | **** Changing ownership for /codecs **** plex_worker | **** Server is unclaimed, but no claim token has been set **** plex_worker | **** permissions for /dev/dri/renderD128 are good **** plex_worker | **** The device /dev/dri/card0 does not have group read/write permissions, attempting to fix inside the container. **** plex_worker | Docker is used for versioning skip update check plex_worker | [custom-init] No custom files found, skipping... plex_worker | Starting Plex Media Server. . .

and then eventually:

I followed some checks in another post https://github.com/linuxserver/docker-plex/issues/359, so maybe that is an issue as my card0 device is user:group root:root. I tried manually changing the group, but it didn't work. I am also just assuming that the worker is trying to use card0, which is why it fails to initialise, but I don't know for sure.

Any thoughts or suggestions?

I thought I'd jump back on here, as it took me a hot minute to find some help and get it done. I think, mostly, it just stems from making sure your orchestrator and workers have the same PUID and PGID. Otherwise, everything seems to break. But I can confirm, everything is now working on Synology NAS.

For anyone who gets stuck with the same, here are my orchestrator/worker files for the Synology NAS pair: Plex Cluster on Synology.zip Note: Replace 192.168.0.2 with your orchestrator local IP, and the PUID and PGID per your user.

I do occassionally have trouble with port 1900 in the orchestrator, in which case, I just comment out that line (or change the external port to 1901), it's for DLNA, which I don't use anyway. This blog post may help though.
