This was working for me previously but seems to have broken after recent Plex versions. I’ve been using the fork at GitHub - djsv23/docker-plex to enable auto-updating the latest Plex versions.
On the latest Plex version, it shows:

It would suck if I had to choose between HW transcoding working or being on a recent Plex version.
