Need help with a Postprocessing script for HW encoding

Trying to get a Postprocessing script to do HW encoding.

This works when tested, but not when placed in the Plex Scripts directory:

#!/bin/bash

inFile="$1"
outFile="${inFile%.*}.mkv"

ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i "$inFile" -map 0 -c:v h264_vaapi -c:a copy "$outFile"

Found the error, just need to find out why this error only occurs when in the Plex Script directory:

[AVHWDeviceContext @ 0x60fa83689a00] Failed to initialise VAAPI connection: -1 (unknown libva error).
Device creation failed: -5.

No device available for decoder: device type vaapi needed for codec mpeg2video.

Found the solution (with ChatGPT)

Needed to add:
export LIBVA_DRIVERS_PATH=/usr/lib/x86_64-linux-gnu/dri

Full Post Processing Script with hw encoding:

#!/bin/bash

# Plex DVR Post Processing

export LIBVA_DRIVERS_PATH=/usr/lib/x86_64-linux-gnu/dri
inFile="$1"
outFile="${inFile%.*}.mkv"

# Hardware encode:
ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i "$inFile" -map 0 -c:v h264_vaapi -c:a copy "$outFile"
rm "$inFile"

Also got quicksyc working with sudo apt install libmfx-gen1.2, but I’m getting better results with vaapi, so I’m sticking with that.
