[icecast] Helix into Icecast2 loopback

Hello.

I've made some progress on the issue. I found a tool called TrPlayer which
is a text mode front end for real player - initially developed for the use
of the visually impaired. The theory is that I can use this and pipe the
live stream into vsound which then in turn is passed into ices or another
source client. Trouble is, I'm having all sorts of trouble compiling
Trplayer on the latest RedHat... something about __pure_virtual being an
undefined symbol...??

Regarding Helix, I am using a Real server not the Helix Community open
source version. The real version is incredibly easy to install and
administrate and you can pick up a free working version with a stream cap at
1mbps from the realnetworks website. I haven't got around to compiling the
open source version but from what I've heard it is efficient and worth
looking into.

Hi Hash,

orry I can't help you with the issue because I haven't been running
a Helix server up to now. The only thing I could imagine working is
when you have a tool that could grab a realaudio-stream from the
Helix server and unpack it to plain PCM wav data. This you can feed
into ices, afaik, and let it re-encode to mp3. If you don't yet have
such a tool it might be a bit of "homework" to do using the existing
realaudio-libs shipped with Helix.

How difficult is building Helix, how easy is it to administrate etc.
I've read a few things about it on the Helix website - but I've not
yet found the time to occupy myself with it. Looks like much work -
is it not? What logfiles, frontends etc. does the Helix Server
provide? And from which point on do you need a real RealServer (where
Helix Server does no longer suffice)?

Regards,
 Stefan
