linux – Input path errors while running FFMPEG and keeping subdirectory structure

My goal is to reduce the size of all .ogg files found under the parent directory “Formatted”, while keeping the sub-directories and files structure the same.

Example

.../Formatted/"test1, test2, test3 and so on"/"files.ogg"

to

.../Contributors/"test1, test2, test3 and so on"/"reduced_files.ogg"

However. While the script runs ffmpeg it seems that the some input file paths gives “Error opening input: No such file or directory”. eg. It either cuts off the ‘h’ of home or adds a ‘.’ to the end of the file extension.

"ome/user1/Downloads/Encoding/Formatted/test1/"file""

or

Parse error, at least 3 arguments were expected, only 1 given in string "oding/Formatted/test1/"file"

Resulting in

.../Contributors/"test1, test2, test3 and so on"/ with only a single file or missing .ogg files.

I’m new to coding, any help is appreciated .
I’ve tried echoing the variables to make sure they are correct but early on in the process echo "3" "$dirName" shows the absolute path being inrorrect.

#!/bin/bash

sourceDir=$HOME/Downloads/Encoding/Formatted
destDir=$HOME/Backup/LEARN/Contributors

find ~/Downloads/Encoding/Formatted/ -type f -name "*.ogg" | while IFS= read -r d; do
#    find -name "*.ogg" 
    echo "1" "$d"
baseName=$(basename "$d")
    echo "2" "$baseName"
dirName=$(dirname "$d")
    echo "3" "$dirName"
dirName_0=$(basename "$dirName")
    echo "4" "$dirName_0"
    echo "5" "$destDir"
outputDir="$destDir/$dirName_0"
    echo "6" "$outputDir"
outputPath="$outputDir/$baseName"
   
#    echo "1" "$d"
#    echo "2" "$baseName"
    echo "3" "$dirName"
#    echo "4" "$dirName_0"
#    echo "5" "$destDirecho"
#    echo "6" "$outputDir"
#    echo "7" "$outputPath"
#    echo "8" "$destDir/$dirName_0/$baseName"
#    echo "9" "$sourceDir"

    mkdir -p "$outputDir"

    ffmpeg -i "$d" -b:a 24k -acodec libopus -map_metadata 0 -map_metadata 0:s:0 "$outputPath"
 
done
