Server for LIVE video broadcasting. what to do?

Question

Video broadcast

Task: redirect the audio stream, for example, from any radio, to a LIVE broadcast of YouTube.
My idea, the audio stream of the radio, should be redirected to YouTube.
How I did it, I downloaded the OBS program (Open Broadcaster Software)
Opened the m3u file with the VLC program in the file, a link to broadcast audio radio, for example air.radiorecord.ru:8101/rr_320
The VLC program plays an audio stream, OBS captures this audio stream in as a video stream, and transfers to YouTube, the video stream is naturally absent, but if we are given such an opportunity, then why not use it, I will insert a picture of this radio there. or something else I'll think of ....
So, how to do it all, so that instead of my computer, other equipment is strained. another computer??
Are there any other ways to rebroadcast an audio stream to a YouTube broadcast?
Or is there some other way to broadcast, WITHOUT programs?
I accept any answers!
