Is it possible to add HW Acceleration after initial setup

[DaisyLee]

Is there a way to add hardware acceleration to the docker after I've had it set up? I am not keen on trying to start all over and the different guides I've found all start you setting it up from scratch.

I'm using the docker manager in Synology DSM 7, with the official jellyfin docker if that matters.

Go to settings in the Jellyfin container then environment and add

DEVICE /dev/dri/renderD128
DEVICE /dev/dri/card0

Create a triggered task from control panel to change permissions on boot.

chmod 666 /dev/dri/renderD128

As long as your /config folder is mounted to a host volume, making configuration changes to a docker container DOES NOT cause you to lose data.

How are you configuring your docker container? A docker compose file or with the DSM UI?

Did you provide /config a folder on the host to write data to?

Yes I did.

Then you can make whatever changes to the container and your data will still be present. It will re-create the container, but only the non-permanent portion that docker manages.
