***Guide*** How to stop Extraneous GPU use when someone starts transcoding a Plex stream

[eagle470]

First you need to get the name of you containers written down. Make sure they are named somethingsimple and easily identifiable as unique to avoid confusion.

You'll need use use the script below, set it to run at "Array Startup"

#!/bin/bash

# Check if nvidia-smi daemon is running and start it if not.
if [[ `ps ax | grep nvidia-smi | grep daemon` == "" ]]; then
    /usr/bin/nvidia-smi daemon
fi

TREX=`docker container ls -q --filter name=T-Rex`

while true; do
    if [[ `/usr/bin/nvidia-smi | grep plexmediaserver` == "" ]]; then
        # If Plex is not transcoding, start the trex-miner container if it is not running.
        if [[ `docker ps | grep $TREX` == "" ]]; then
            echo "No Plex, starting Trex."
            docker start $TREX
        fi
    else
        # If Plex is transcoding, stop the trex-miner container if it is running.
        if [[ `docker ps | grep $TREX` != "" ]]; then
            echo "Plex running, stopping Trex."
            docker stop $TREX
        fi
    fi
    sleep 1
done

You may need to change trex-miner to match what your container is named.

 

plexmediaserver is the name of the process that appears in the nvidia-smi control panel. I had to make a guess as I couldn't see the whole thing and can't figure out the command to show it to me. I am running the Hotio container currently but have had this working with the Plex, inc, Linuxserver and binhex versions as well.

 

I did not write this script, it is borrowed.
