# Script Name: Plex Transcoding & Docker Management Script
|
|
# Author: Admin9705 & Reddit
|
|
# Description:
|
|
# This script monitors Plex transcoding activity on a specified
|
|
# GPU device. If Plex is detected using the GPU, it resets a
|
|
# restart counter. If Plex does not use the GPU for a defined
|
|
# number of checks, it increments a counter. Once the counter
|
|
# reaches a threshold, the script restarts a specified Docker
|
|
# container. The script is designed to run indefinitely and
|
|
# includes logging for monitoring and troubleshooting.
|

# NOTE: Setup for AV1 with Intel ARC; could be modified for
|
|
# Other Cards
