Can't play German radio streams

I’ trying to play the German radio live streams:

and

When I put these URLS into Web Radio, Volumio says “Failed to decode Livestream - rbbKultur live hören | rbbKultur

However, these URLs work fine in a browser. Any ideas?

The URLs link to a webpage not a music stream.

@chsims1 @sjc

here they are for Livestream - rbbKultur live :

they are eazy to find on there site

open google chrome on a pc or mac, go to the site and press play.
continue right click mouse and choose inspect and then choose network and then media, refresh the page and click on the stream and right click and copy link address, and now you have the stream.
