DLNA/UPNP: Get Metadata from UPNP-Server (like Album-Art)

Hello,
I would like to use DLNA/UPNP binding to control my AssetUPnP server on which my CD collection is stored. I have created a small widget that lists the contents of the AssetUPNP server.

  1. Is it possible to access the link for ‘Albumart (Albumcover)’ in addition to the text information (band name, album name, title etc.)? The data is at least listed in the debug log.

  1. After selecting a song from an album (last level of the listing), the first level of the server content is displayed again (Artists, Genre…). Can this be prevented so that the complete song list of the CD is always displayed?

Any idea is welcome.

Thanks

What specifically are you referring to? Is it the upnp:class entry you are referring to? That can contain many values and is not something I would call an album type. It is the object type of an entry in the UPnP directory (which can be albums, tracks, directories…).

Sorry for the typo. It has to be ‘albumArtUri’ resp. ‘Albumcover’ see example

That is available on the renderer, not the server at the moment. It gets shown when playing, not when browsing.
