[Live-devel] Need Help with test*Streamer From a Live Source

Yes.  'liveMedia' code *must* be called from within one thread only. 
The only liveMedia-related thing that you can do with the other 
thread is set a global variable that can (for example) be seen by the 
other (i.e., liveMedia event loop) thread to indicate an event.  For 
example, if you are using the "doEventLoop()" 'watchVariable' 
feature, you can set the 'watchVariable' from within the second 
thread.

If you are using "MPEG4VideoStreamDiscreteFramer" (instead of 
"MPEG4VideoStreamFramer") between your input source object and your 
"MPEG4ESVideoRTPSink" object, then the right thing should happen.
