I am using binhex-plexpass docker. I have a E3-1275v6 CPU. In plex server settings I have Use hardware acceleration when available turned on. Is there anything else I need to do with unRAID or plex to get it working?
I am not seeing the hw tag in the info when looking at server transcode info.
Add a video device to the Plex container with a value of /dev/dri:/dev/dri. I also hope you rebooted your server after making the other config changes.
Lastly, hw transcode is only available to Plex Pass users so make sure you are a Plex Pass member.
