In most cases, map_metadata should be used instead of
rewrite_metadata.. Let's see:

live_desc = ref 'qqq'
def live_on_connect( m )
live_desc := m[ 'ice-description' ]
print( json_of( !live_desc ) )
end
live = input.harbor(
id = "live",
password = hrb_pass,
port = hrb_port,
on_connect = live_on_connect,
hrb_mp
)
live = map_metadata( { [( "description", !live_desc )] } , live )
live = on_metadata( (fun (m) ->
begin
print( json_of( m ) )
print( json_of( !live_desc ) )
end),
live
)
That should do..
Now, regarding your ultimate goal, if you want to pass this to the
"description" parameter of output.icecast, this parameter is set once
and for all when connecting the source stream to your icecast server.
If you want to change it for each new harbor input, you'd also have to
create and destroy the corresponding output.icecast.. And in this
case, I don't think you need to go through the burden of passing
description using metadata..
