Roon Extension: CD Ripper v0.6.1 (2022-12-24)

Swiss · August 10, 2019, 11:52am

sorry for the confusion. Started new topic on ROCK CD Ripper performance.

Stef_Dahl · August 12, 2019, 10:03pm

Only on Rock or Linux system, none on Roon server Win10 ?

Daniele_Piancastelli · August 13, 2019, 11:13pm

I’ve a problem with my bluray device: when i launch the drive configuration, after a lot of attempts with differents offset displayed, the result is “Drive offset can’t be determinated, try another disc”.
Ok, this in a problem not of the extension in particular (dbpoweramp show me similar popup) but i can’t find information nowhere.
Suggestion? I’ve to change the device?
On Accuraterip the device is “purged”
http://www.accuraterip.com/driveoffsets.htm
ASUS - SBW-06D2X-U [Purged]

Jan_Koudijs · August 14, 2019, 6:17pm

I haven’t come across any purged drives before, so I had to look up the meaning (it’s at the top of the page you linked):

A small number of drives have [Purged] as the offset, these drives were found not to have a constant drive offset (perhaps different manufacturing batches, or firmwares), as such they have been removed from AccurateRip’s drive database (should you have one of these drives, 3 matching key disks will be required to configure AccurateRip).

So it might be necessary to perform the disk configuration on three different CDs to convince the underlying software that the offset is constant. I suggest to check the extension log to see if there is any hint about this in it (the status message is pretty generic). You get the log with the Docker command:

docker logs roon-extension-cd-ripper

The error message is probably somewhere at the end of the log. If you search for the status message and copy some lines above and below it then I can also have a look.

Jan_Koudijs · August 14, 2019, 6:31pm

Unfortunately Linux only, Docker for Windows can’t be used due to the virtual networking it uses that isn’t supported by Roon.

But there are different types of Linux systems:

Linux desktop or laptop PC
Single board computer running DietPi, e.g. Raspberry Pi
Small Green Computer’s sonicTransporter

WARNING:whipper.common.accurip:entry not found in AccurateRip database

If you try with a different CD and get this same message then I guess you have to try with a different drive

There is also a connection error when it tries to download a file: http://www.accuraterip.com/accuraterip/4/3/f/dBAR-007-000dcf34-0050a303-520b7d07.bin. This file exists. Can it be an internet access issue?

Daniele_Piancastelli · August 15, 2019, 6:05pm

A new device is in on the way. For my rips with the notebook i use an old Liteon device (perfect for cd that have problems) but it’s ugly close other hi-fi stuff
So i’ve tested my other bluray slim unit (nice ) with this results

My connection work fine, how i can investigate this error?

Jan_Koudijs · August 15, 2019, 6:27pm

Have you tried the extension with this drive? (assuming it is external). A drive from the CD/DVD era has a good chance of being well supported. I use the same approach with my Plextor drive from the thrift store.

This might also give a hint about the meaning of the connection error.

Daniele_Piancastelli · August 16, 2019, 8:27am

No, i can try today.
Today also will arrive the new device, so i’ll test both and i’ll let you know the results

Daniele_Piancastelli · August 16, 2019, 5:21pm

Ok , i’ve tested the new device (succesfully tried on dbpoweramp) but same errors…
I think the problem is “whipper”

Jan_Koudijs · August 16, 2019, 6:21pm

Can you do a quick check regarding the connection issue?

Open a console on the container:

docker exec -it roon-extension-cd-ripper bash

And then download the specified file:

curl -O http://www.accuraterip.com/accuraterip/4/3/f/dBAR-007-000dcf34-0050a303-520b7d07.bin

Does it download?

You already tried with different CDs, right?

Daniele_Piancastelli · August 16, 2019, 11:22pm

Ok, it work. And i’ve successfully setted the offset. But…

Jan_Koudijs · August 17, 2019, 8:45am

Do you know what made it work?

Whipper uses MusicBrainz to get the metadata, for the disk you try to rip no metadata is available. The purpose of the CD Ripper is to rip a CD and push the result to your library in a single run. For this reason I decided to do nothing when there is no metadata available. The alternative is to rip the disk and move it to your library without metadata, but then Roon will probably not identify it and you end up with an unidentified album. I’m not a fan of this approach.

How do you look at this? I could add an option to even rip when there is no metadata available.

Daniele_Piancastelli · August 17, 2019, 12:05pm

I’ve tried with 5 different CDs. With this one Boston the device successfully configurated

stdout: "Read offset of device is: 6."
-> CONTINUE 1 Changed {"message":"Read offset of device is: 6.","is_error":false}
-> CONTINUE 1 Changed {"message":"Read offset of device is: 6.","is_error":false}
whipper exited with code: 0
-> CONTINUE 1 Changed {"message":"Drive configuration successful!","is_error":false}
-> CONTINUE 1 Changed {"message":"Drive configuration successful!","is_error":false}

The previous test ripping faild for metadata missing. I can understanding your point of view about no metadata available but i think is better give an option (preferably at setting level so you can choose one time and not for every rip). For example i buy a lot of new albums or minor albums without relative release in musicbrainz.In this cases i add manually the entry on musicbrainz but not immediately (a couple of hours, a day…) but i prefer have the album folder available in Roon (also with “track 1, track 2 …” and nothing else) and ready when Roon will recognize the new release or for the tag editor process that i’ll do.

I’ve performed a second ripping test with a bad result:
in this case the metadata are available (my release is this one )

I happen to have the exact same CD (same release). I am now ripping it on my NUC running Arch Linux (metadata was found). When finished I will also rip it on a Raspberry Pi. This is a good reference CD for the moment (although ripping is slow for me, it might be a bit scratched).

You are running Ubuntu, right? On what hardware?

Your log again shows a network error, I don’t know what is going on there.

Daniele_Piancastelli · August 17, 2019, 5:26pm

Ubuntu server 18.04 on a self-made server hd plex (asus strix mini itx, m. 2 and ssd for storage).
Network error probably is for a bad whipper configuration?

Jan_Koudijs · August 18, 2019, 3:29pm

I could successfully rip the CD on both systems.

The Docker container should take care that everything is pre-configured. Did you install the CD Ripper via the Extension Manager?

Can you check the ip address that is reported by the following command:

cat /etc/resolv.conf

Run the command first in a command window and after that in a console on the container:

docker exec -it roon-extension-cd-ripper cat /etc/resolv.conf

Is there a difference in output?

Daniele_Piancastelli · August 18, 2019, 3:55pm

Yes

nameserver 127.0.0.53
options edns0

# No DNS servers known.

Jan_Koudijs · August 18, 2019, 4:59pm

We might be up to something.

Can you follow the steps in this guide, to see if DNS is the problem?
