Hi,
My way is to call an API from liquidsoap and populate a database. From
this database you can make what you want (and have a metadata history)
#!/usr/bin/lisquidsoap
stream_id="20"
stream_name="MY RADIO STATION"
[...]
def store_meta(m) =
song = url.encode(m["title"])
ignore(http.get("http://server:port/api/setMetadata?id=#{stream_id}&metadata=#{song}";))
log("#{stream_name} #{stream_id} - metadata:#{song}")
end
[...]
source = on_metadata(store_meta, source)
[...]
Yoann!
