foobar2000 Accessing UPnP DLNA Example (also Python upnpclient example)

README.md

Generate M3U Playlist from foobar2000 UPnP/DLNA Server

I have many songs stored in foobar2000 on Windows, and I wanted to listen to them from other Macs or tablets. foobar2000 mac and foobar2000 mobile seemed suitable for this purpose, but it took a long time to list the songs. So I used this script to create a playlist in advance to save me the trouble.

How to use

• step 0: create playlist in your foobar2000
• step 1: install UPnP/DLNA Renderer, Server, Control Point in your foobar2000
  • and make some configuration
• step 2: install pip packages
  • upnpclient
• step 3: run python3 upnp.py

ObjectID explained (foobar2000)

+ root : ObjectID = 0 
+--+ Playlists : ObjectID = 0/0 
   +--- Playlist 1 : ObjectID = 0/0/0
   +--- Playlist 2 : ObjectID = 0/0/1
   +--- Playlist 3 : ObjectID = 0/0/2
        ...
   +--- Playlist n : ObjectID = 0/0/n
+--- Media Library : ObjectID = 0/1 
+--- Playback Stream : ObjectID = 0/2
