Nvidia transcoding on Unraid Docker

Channels DVR Server
#1

Group,

I've been trying to get Channels to do hardware transcoding, but I can't seem to get it to change from software to hardware. I do have Plex also installed in Unraid Docker and it using Nvidia Hardware transcoding correctly.

I've done the following:

On my Unraid Server:

cat /boot/config/go

#!/bin/bash

Start the Management Utility

/usr/local/sbin/emhttp &
modprobe i915

root@UNRAID-1:~# lsmod | grep i915
root@UNRAID-1:~# modprobe i915
root@UNRAID-1:~# lsmod | grep i915

I'm still seeing transcoding as software still.

Please help

Are you using the ChannelsDVR-NVidia template?

#3

Yes I am

#4

Can you run a hwe test and collect all the results from the log?

ran the curl command from a remote computer (Mac). Here is the output from the channels log.

This seems to be the issue, I guess a missing driver somewhere.

#7

I know it works on Linux but not sure if anyone has tried on unraid before.

#8

My Unraid build words with NVIDIA cards, https://github.com/timstephens24/docker-templates (https://github.com/timstephens24/channelsdvr-docker)

#9

Looking at your output it doesn't look like you have either the Unraid Nvidia Plugin or the NVIDIA-Driver plugin (anything after 6.9.0-beta35) installed. Can you verify those are there and working with a valid UUID for your graphics card? It should look something like "GPU-9cfdd18c-2b41-b158-f67b-720279bc77fd" and you can pull that from their of those plugins.

#10

Hi @timstephens24...yes I do have the Unraid Nvidia Plugin installed and I'm on 440.59 driver version. It is working correctly with Plex.

#11

@tmm1, I was able to fix the issue. It looks like you are missing "--runtime=nvidia" in the extra parameters section of your docker build.

#12

@timstephens24 thanks fo the info. I was able to find the issue with the docker build I was using and looks like I was able to fix it.

No problem, that was going to be my next suggestion after seeing your reply. Enjoy!

#14

Is this something that I can add to ChannelsDVR-NVidia.xml?

#15

I think you should be able to. I've see other Docker apps that have it part of the the extra parameters...maybe @timstephens24 can answer that.

#16

From what I know it should be on there (https://developer.nvidia.com/nvidia-container-runtime). It's default on my template and other's that I've seen.
