Regarding the TrueNAS Plex APP.
The middleware has problems detecting the UUID of the nvidia GPU and hence fails to populate ‘NVIDIA_VISIBLE_DEVICES’.
As a result HW transcoding does not work.
Now, it is easy to get the UUID, just run the following inside the TrueNAS shell.
nvidia-smi -L
However, the Plex APP configuration does not allow the user to manually set the UUID env ‘NVIDIA_VISIBLE_DEVICES’.
You get an error that this has been configured by the developer.
Please allow the user to set this value manually, at least until the middleware is able to detect the UUID all the time.
