Title: Multiple Genre values with DLNA media library
Post by: janderuijter on October 04, 2016, 02:20:58 am

When I define a file-share as "Main Library" and import the library the genre tag, which often contains multiple genre values, are nicely recognized and handled. When for example a music file has a Genre tag "Genre1; Genre2; Genre3" the file will be shown under the Genre Genre1 and Genre2 and Genre3 (I don not talk about sub-genre and genre trees).

When using the same media server and the same files and configuring "Playing From Library Server -> Music Library" where "Music Library" is a DLNA server only the first value of the Genre tag becomes recognized. Following my sample I'll be able to find the file under Genre - Genre1 but not under Genre2 or Genre3.

I tried both Twonkey and MinimServer as DLNA server with the same failing result.

Do I have to configure something specifically at MC or did I hit a bug?

Kind Regards,
Jan de Ruijter

It's not a bug, it's a limitation of the DLNA device.  Most of them don't read a list

Hi ferday,

Thanks for your reply.

When I access the same DLNA server using PlugPlayer (iOS) or BubbleUPNP (Android) the genre tagging works ok. This leads me to the conclusion that the DLNA server is not limited to one Genre only.

Actually it is neither a bug, nor a limitation of the device, nor even a limitation of DLNA...

It is in fact a limitation of the basic underlying UPnP specification for Digital Media Server. This specification foresees many types of track meta-data tags (title, album, artist, genre, album-art, etc.) and some of these are allowed to have multiple tag instances (e.g. artist) but others are only allowed to have a single tag instance (e.g. genre).

Hi AndrewFG,

upnp.org states:

B.5.1 upnp:genre
Namespace: upnp Property
Data Type: xsd:string
Multi-Valued: YES

Description: The upnp:genre property indicates the genre to which an object belongs.
Default Value: None.

The "Multi-Valued: YES" does mean that multiple values are permitted. Using other applications as mentioned before do show multiple values for Genre, these apps are using the same UPNP/DLNA. So I still think multiple values should be possible.

But thanks anyway for your reaction.

Regards,
Jan de Ruijter

Oops..

You are quite correct. Sorry for that.
