If you are referring to the "now playing" metadata title, description, etc contained in the stream, the easiest way is to use Direct Streaming. It will forward the source stream to clients as-is.
You can already connect ministra with the panel. Set the line in the panel as stalker portal and use it in ministra.
In older stalker portals (not ministra) you have to copy these 3 files.
You have already tmp links in ministra for flussonic.
