bash ffmpeg find and spaces in filenames

Question

I have a problem with ffmpeg and spaces in folders/filenames. My code looks like this:

cd /volume1/PUBLIC/Musik/AutoConvert
find . -type d -exec mkdir -p -- /volume1/PUBLIC/Musik/Converted/{} \;
find -type f |sed 's|./||' |while read NEWNAME; do
ffmpeg -i ""/volume1/PUBLIC/Musik/AutoConvert/"$NEWNAME""" -codec:a libmp3lame -qscale:a 2 "/volume1/PUBLIC/Musik/Converted/"${NEWNAME%.[Ff][Ll][Aa][Cc]}".mp3"
echo done with file: "$NEWNAME"
done

But that fails with ffmpeg if there is a space anywhere. My Folder Structure looks like that:

user@NAS:/volume1/PUBLIC/Musik/AutoConvert$ find -type f |sed 's|./||'
A B/C.mp3
A B/C D.mp3
A/C D.mp3
A/C.mp3

The /Converted/A/C.mp3 does work, but thats the only one. All the others with Spaces in Folder oder Filename fail.

[NULL @ 0x20bb3e0] Unable to find a suitable output format for '/volume1/PUBLIC/Musik/Converted/A/C'
/volume1/PUBLIC/Musik/Converted/A/C: Invalid argument
done with file: A/C D.mp3

[NULL @ 0x11bf280] Unable to find a suitable output format for '/volume1/PUBLIC/Musik/Converted/A'
/volume1/PUBLIC/Musik/Converted/A: Invalid argument
done with file: A B/C D.mp3

[NULL @ 0x11f93e0] Unable to find a suitable output format for '/volume1/PUBLIC/Musik/Converted/A'
/volume1/PUBLIC/Musik/Converted/A: Invalid argument
done with file: A B/C.mp3

If i don't use the double " on ffmpeg -input i get the error:

/volume1/PUBLIC/Musik/AutoConvert/A: Is a directory
done with file: A B/C.mp3

/volume1/PUBLIC/Musik/AutoConvert/A: Is a directory
done with file: A B/C D.mp3

/volume1/PUBLIC/Musik/AutoConvert/A/C: No such file or directory
done with file: A/C D.mp3

It looks like i'm on the right track... just way too far from my goal.

Can anyone offer some help?

Maybe this code can help you

#!/bin/bash
cd /volume1/PUBLIC/Musik/AutoConvert 2>/dev/null || { echo "The folder is unavailable."; exit 1; }
find . -type d -exec mkdir -p -- /volume1/PUBLIC/Musik/Converted/{} \;
while IFS= read -r -d $'\0' NEWNAME; do
    ffmpeg -i "/volume1/PUBLIC/Musik/AutoConvert/$NEWNAME" -codec:a libmp3lame -qscale:a 2 "/volume1/PUBLIC/Musik/Converted/${NEWNAME%.*}.mp3"
    echo "done with file: $NEWNAME"
done < <(find . -iname '*.flac' -printf '%P\0')
