I have had Plex hardware transcoding working for a long time and this AM I installed a GPU to pass through to a VM. I have lost hardware transcoding on Plex. The dropdown box only shows auto so I cannot pick it from the Plex settings. I am on Unraid using the official Plex docker. I understand that I may need to update the Plex preferences XML file. The problem is I have no idea what to put in there, as I have found the following on the Plex forums. " User plex is added to the group of the first card found To manually override the device used, specify HardwareDevicePath=“/dev/xxxxxxxxx” in Preferences.xml (while Plex is stopped) udev should be adding both devices to the same group (render)" I am unsure what to replace the XXXX with or where to find out. Thanks for any help you can provide. ---
