Multiple values are separated by a NUL character and this is written by your tagging program. Some tagging programs (for example, Mp3tag) use \\ in their user interface as a separator for multiple values and write a NUL character in the ID3v2.4 file in place of the \\. In this case, MinimServer is seeing the NUL character in the tag value, not \\.

If Emby is writing a / character into ID3v2.4 files to separate multiple values, this is incorrect and will not work with a server that implements the ID3v2.4 specifcation correctly, such as MinimServer.

If all tracks of the album are tagged with the album artist "Rosemary Clooney|Duke Ellington", you should see this artist name in the AlbumArtist index and in the Artist index. If any of the tracks is tagged with no value or a different value, the album artist value for this album will be [unknown].

If an album has multiple artists, MinimServer expects these to be tagged as Artist, not AlbumArtist.

Does this explain what you are seeing?

I read it a couple of days ago but now cannot find it again. It allows me to set the display from Rosemary Clooney|Duke Ellington to Rosemary Clooney / Duke Ellington as displayed.

It's possible there's an alternative as MinimServer is VERY configurable, but the only way I know to translate Rosemary Clooney|Duke Ellington to Rosemary Clooney / Duke Ellington is to use the tagUpdate functionality:

Code:

@ALBUMARTIST=Rosemary Clooney|Duke Ellington
=ALBUMARTIST=Rosemary Clooney / Duke Ellington

The problem with this approach is that the "artist" Rosemary Clooney / Duke Ellington will appear in the albumartist index and searches.

I've been setting up a MusicBrainz Picard workflow for a friend over the last couple of days (which I might post to the forum in the next couple of days because it works so well with MinimServer) and the solution he's using (same as mine) is:

Tags:

Code:

ALBUMARTIST: Rosemary Clooney; Duke Ellington (multivalued)
DISPLAY ALBUMARTIST: Rosemary Clooney / Duke Ellington

MinimServer config:

Code:

itemTags:Display Albumartist
tagFormat: Albumartist.displayformat={$Display Albumartist}

NOTE: If you don't want to fully populate the display albumartist tag then you'd need to add:

Code:

tagValue: Display Albumartist.default={AlbumArtist}

Then use tagUpdate to remove one of the artists from the album:

Code:

@ALBUMARTIST=Rosemary Clooney
&MUSICBRAINZ_ALBUMID=01555e07-19fa-4fe4-be62-66dadcf233df
-ALBUMARTIST=Rosemary Clooney

Obviously you lose Rosemary Clooney from the Artist (albumartist) index (she'll still appear under the All Artists index and in searches) but at least she's credited on the album, and the underlying tags are complete.

If you don't have a MUSICBRAINZ_ALBUMID tag then you'd need to use as many tags as uniquely identify the album e.g. ALBUM + YEAR.
