Here's a link to the music files that trigger the bug (if relevant): This happens with any music file I give it.
Setup
- OS: Kubuntu 25.04
- Python version: 3.13.3
- beets version: 2.5.1
- Turning off plugins made problem go away (yes/no): no - I disabled every plugin but
convertand still have this issue
My configuration (output of beet config) is:
directory: /music/Library
library: /music/beets/musiclibrary.db
artist_credit: no
replace: {
"“": '',
"”": '',
'"': "",
"’": "'",
# remove ascii control characters
'[\x00-\x1f]': "_",
# spaces at the beginning and and
'\s+$': "",
'^\s+': "",
":": "",
"\\?": "",
}
import:
move: yes
bell: yes
timid: yes
paths:
default: $albumartist/$album%aunique{}/$track $title
singleton: $artist/Singles/$title
comp: Compilations/$album%aunique{}/$track $title
plugins:
- convert
convert:
auto: yes
format: mp3
dest: /music/Originals
max_bitrate: 256
no_convert: "format:MP3 , format:FLAC , format:OPUS"
delete_originals: true
formats:
mp3:
command: ffmpeg -i $source -hide_banner -loglevel error -acodec libmp3lame -ar 44100 -b:a 256k -vn $dest
extension: mp3
aac:
command: ffmpeg -i $source -c:a aac -b:a 256k -c:v copy -map_metadata 0 -map 0:a -map 0:v? -disposition:v:0 attached_pic $dest
extension: m4a
If I set convert's config to use auto: no, import works fine.
