`database access error: Invalid character in a Base-64 string.`

[calestyo]

Hey.

Recently I've had a weird error with the EAC plugin of CTDB:

$ cat clipboard.log
- CUETools DB Plugin V2.1.6 -

[CTDB TOCID: buTex5nNhqZ5iG6hROEwz2TDJ60-] database access error: Invalid character in a Base-64 string.

That happened repeatedly when ripping the same CD again.

Any ideas?

Thanks,

That happened repeatedly when ripping the same CD again.

Repeatedly means?

• It happens reproducibly every time?
• Sometimes it works, sometimes the error occurs?

Did it only happen with this CD?

It happens reproducibly every time?

With EAC, it happened on all extractions of that particular CD which were:

• twice via Test&Copy image (without considering C2 errors)
• once via Test&Copy tracks
• once via Test&Copy image (with considering C2 errors)

(I can attach all the log files if that helps).

In all cases AR was fine.

So far it happened only with this particular CD (and I've ripped about 1300 - i.e. my whole collection).

Haven't come to try CUERipper, yet.

@calestyo Thanks for the clarification.
Can you find out, which character in which field causes the Invalid character in a Base-64 string error?

[calestyo]

Which fields exactly do you mean? Something in EAC? Something in the DB?

[c72578]

Which fields exactly do you mean? Something in EAC? Something in the DB?

Fields in EAC like: CD Title, Artist, Track title, …

Which Metadata-Provider did you use to get the metadata for the affected CD?

@c72578 This looks like it may be a server-side error.
Looking at the xml, 4B2152DC appears damaged.

Which Metadata-Provider did you use to get the metadata for the affected CD?

I basically leave always everything as is, i.e. no meta-data download from other sources, except for CD-TEXT. The goal is to make an as-pristine-as-possible image (which is why I include CD-TEXT),... any other metadata like musicbrainz can be retrieved later on from the image.

And the CD in question does not have CD-TEXT, so EAC sets everything Unknown Title, Unknown Artist and Track n.

@ha-korth Thanks for having a close look at the entry in the database and @calestyo for providing further details.
So, this issue concerning buTex5nNhqZ5iG6hROEwz2TDJ60- and 4B2152DC should be transferred to https://github.com/gchudov/db.cue.tools/issues

I've got an Database Error too:

Do you want me to re-report it there, or is there anything else I can reasonaby do?

[calestyo]

btw: I've also just noticed, that for the particular disc, CUERipper doesn't seem to find the MusicBrainz metadata, whereas for all other discs of the album it seems to do.
