Hello,
From what we understood by discussing and testing on IRC, we came to the
conclusion that Shoutcast has a particular way of sending and handling
meta-datas.
Apparently, the official Shoutcast plugin for Winamp, as well as Edcast by
Oddsock, send metadatas without using the GET way. We also believe they do
not use icy-infos, since those are sent by the source only at the very
beginning of the connection, which would be unpractical for mp3 tags.
This way of sending metadatas remains unknown for liquidsoap at the
moment. As a consequence, using Shoutcast DSP for Winamp toward
input.harbor lead to a total lack of any tag whatsoever, aas highlighted
by the following log :

2009/02/13 01:52:42 [lang:3] Live terminé
(and yes, there has been several attempts to send metadatas during that
minute of streaming).
The conclusion is that it would be great to have input.harbor support that
special Shoutcast-way of handling metadatas.
Icecast server seems to be able to handle them.
Also, edcast (an icecast/shoutcast source client), when configured as
"Shoutcast", sends them the very same way... AND it is open-source. So you
may be able to look at their code and see how it works.
If it can be of any help, here is Edcast source directory :
http://svn.oddsock.org/public/trunk/edcast/src/
The solution must be somewhere inside this.
