I have recently updated to Version: 6.9.0-rc2 and attempted to get hardware transcoding to work for Plex via GPU passthrough (GTX 1060).
I have the Nvidia Driver Package installed; added the extra parameters and Nvidia driver capabilities and visible devices variables to the plex docker. Hardware transcoding is enabled in plex, however it will not use my GPU to hw transcode - using my CPU only.
I have checked using the watch nvidia-smi command in the console, as well as used the GPU statistics utility.
Screenshots attached.
Am I missing something? Did I do something wrong?
