Create Smart Playlist from existing library

[AndyBerlin]

Dear all, sorry to ask, as this must have been solved before but I cannot find it: How do i create Playlists from an existing library?
Background: I have a mid-size well sorted library of 10k tracks (all ripped from CDs) on my Synology, that I access via the Yamaha Musiccast App to play at my place.
Until recently, I used iTunes Server to create smart playlists, e.g. "all Pop tracks except from ABBA that are longer than 1:00 minute".
Synology no longer supports iTunes Server, so I I would like to now do this using Asset UPnP.
So my question: How do I create a bunch of such smart playlists in the Asset UPnP web interface, so that I can easily find them later in the MusicCast app?
Thanks a ton in advance!

Use Dynamic Browsing, however we have no minimum length specifier.

Dynamic Browsing is definitely the right place to start. It should let you build views based on your existing library metadata without having to manually create thousands of playlists.

For example, you could create a browsing view for Genre = Pop and then exclude Artist = ABBA. You can then access that view through the UPnP client, assuming MusicCast exposes the corresponding Asset UPnP browsing structure.

The one limitation here is the 1:00 minimum-length condition mentioned by Spoon. If that condition is essential, you may need to handle it through your library metadata or another filtering method, since Asset UPnP doesn't appear to provide a minimum track-duration criterion in Dynamic Browsing.
