I'm trying to process an audiobook (m4b) and I keep getting this error:
Error occured while merging '(PosixPath('/input/Anvil.m4b'), 'm4b', 1): [Errno 1] Operation not permitted: '/input/Anvil.new.m4b''

i run bragibooks using this command on windows with WSL
sudo docker run --rm -d --name bragibooks -v /mnt/d/Plex/audiobooks_temp:/input -v /mnt/d/Plex/audiobooks_out:/output -v /mnt/d/Plex/bragibooks_config:/config -p 8000:8000/tcp -e LOG_LEVEL=DEBUG ghcr.io/djdembeck/bragibooks:main
