You should also change the variable "reuseFirstSource" (near the top of 
"testOnDemandRTSPServer.cpp") to "True".  This tells the server not to try 
to create a new copy of the input source (in this case, 'stdin') for each 
new client, but instead to reuse the existing source.

The change noted above will probably fix this.

If you're still having problems with this, then try the following:
1/ Create a data file with output from your encoder.
2/ Rename this file as "test.<whatever>" (e.g., "test.m4v" for MPEG-4 
Elementary Stream video).
3/ Run the (original, unmodified) "testOnDemandRTSPServer", and see if you 
can play a stream from your file.  If you can't, then your file is probably 
in the wrong format, and you'll need to check the settings on your encoder.
