CasparCG import internet radio

Hello, i need information, what is the easiest way for import online radio (IP).
How I can import radio livestream (url) in CasparCG or RedCast playlist in the back of the images and video without audio? Can you help me?

I found following works in Server 2.07

I found the same example in web. But,
How i can implement it into .html file?

When I would like play mp3 stream, it didn’t work, CasparCG sand ffmpeg header error. It works when i play aac stream radio.
