[Abcde-users] Problem with 'abcde -d disc.flac'

[Bjørn Forsman]

Hi all,

My name is Bjørn and I'm in the process of importing/backing up all my
CDs to my computer (surprise!).

In the manual, I find the 'abcde -1 -o flac -a default,cue' command.
This seems like my best option since it preserves the whole CD (AFAIK)
and allows encoding to different formats later, e.g. 'abcde -d
disc.flac -o mp3'.

However:

$ abcde -d October.flac -o mp3
Grabbing entire CD - tracks:  01 02 03 04 05 06 07 08 09 10 11
MusicBrainz lookup returned an error "Not Found"
Selected: # (template) (Unknown Artist / Unknown Album)
---- Unknown Artist / Unknown Album ----
1: Track 1
2: Track 2
[...]

It doesn't see the that this is my U2-October album, and will not tag
the mp3s correctly :-(  (It did work work correctly when doing 'abcde
-o mp3' though, but that doesn't help much since I'd like to keep a
master copy.)

Looking in the ML archive I find the "Musicbrainz lookup from flac
image" post[1]. I apply that patch[2] but still I'm getting that
"Musicbrainz lookup" error when running against the disc.flac image.

In the abcde manual I also find the '-C [discid]' flag. But that
doesn't work either:

$ abcde -d October.flac -o mp3 -C a309a30b
cat: /home/bf/Music/U2-October/abcde.a309a30b/cddbdiscid: No such file
or directory
[INFO] The disc does not contain any tracks. Giving up...

(Looking at that output, I guess I had wrong expectations for the -C
option. It clearly relies on something other than the flac image.)

Is there anyone here who knows how to make abcde work for this use
case? I'd like to backup the CDs with the ability to make e.g. mp3s
from that backup later (with tagging).

Best regards,
Bjørn Forsman
