The current version of Y-Radio broke with the Sailfish OS 2.0 update. A fix release has been submitted to Harbour QA and is also available now on OpenRepos and now requires Sailfish OS 2.0.
The reason, a bug in glib related to rtsp URLs prevents rtspsrc from working properly and the fix didn't get into 18.104.22.168.
Luckily Sailfish OS 2.0 moved to gstreamer 1.4.5 and now includes (a working!) hlssrc so we can finally use the higher quality HLS streams provied by YLE.
