Chromecast URL Player - How does it work?

Hello @ all,

yesterday I added my Chromecast (v1) to openHAB.
I linked all the items and added it to my sitemap.

In the rules I noticed that the “Radio” Switch would send the Webradio Live Stream URL to the URL Player.
This rule works fine, but it won’t play the live radio… after long waiting period I stopped it.

Does URL Player work with the first version of Chromecast and if it works, how can I use it?

Thanks a lot in advance!
