I am looking for a linux application capable of 
streaming RealText live to a Helix Universal Server (HUS).

There is a (old) demo application(DA) for Windows at:
http://www.realnetworks.com/resources/toolsplugins/realtextbroadcast.html

The sourcecode for this program is in the Real SDK:
http://www.realnetworks.com/resources/sdk/index.html
(You get a file "rsg2sdk_r4.zip" which contains a
directory "rmasdk_6_0/samples/intermed/exlvtext/"
with the code.)

I was able to compile the application on linux and
link it (dynamically) with the libraries of the
helix universal libraries "rtlive.so.9.0" and
"encnet.so.9.0", but if i start the program,
i get a segmentation fault.

The available windows executable (DA) is bundled
with old RealServer DLLs, but there is no
output (or reaction at the HUS) when using this
program with a HUS.

If it is possible to connect to a HUS with a
compiled linux DA, i would like a short
walkthrough of the neccessary steps or
requirements to set up such a connection and/or
a patch for the DA source.
