[Icecast] multiple source clients into a single icecast server
*snip* removing the shotgun to field
Although it might be possible to do this, it is most likely not what you're
after. One can of worms being timing and delay screwing with synchronization.
I'd suggest to do the part where you juggle all those audio feeds outside
the icecast scope, e.g. Some audio-conferencing/voip solution and feed the
result to icecast using a source client.
If you really don't care about aforementioned problems: run all those ices
instances to individual mount points, then play each of them back into a
sound-server using e.g. ogg123 and source that into ices/icecast as
/cacophonia.ogg ;-) -- you've been warned.

I would like to know if anyone has experience 'sinking' multiple source
clients (ices2.0.x) into a single icecast streaming server? I would like to
source content from a large number of streaming clients (dozens or maybe even
hundreds), composite them into a single stream (essentially like an audio mixing
board) and then have the streaming server serve up this new composite content to
only a few listeners.
It is somewhat the reverse of a traditional streaming server configuration (a
single or very small number of source clients into the streaming server and
numerous listening clients). Here is what I have in mind:
Many ---> |-------------|
source ---> | Streaming |--------> small number of listener
clients
clients : | server |
: | |
---> |-------------|
Can this be done with icecast as implemented? If not and code modifications are
necessary, what modules might one need to modify? Ideally, I would also like to
apply a variable gain to each source client's channel independently before
the composite process. Any help would be most appreciated.
Sincerely,

Any help would be most appreciated.You should be able to do that using Liquidsoap. A single running liquidsoap instance can accept multiple icecast/shoutcast source connections, create a single stream out of them and stream the result to Icecast. You can contact us at savonet-users at lists.sourceforge.net or lookup online at http://savonet.sf.net/ for more details.. Romain
