You may be seeing (IP multicast) packet loss somewhere between the 
streamer app and VLC.

I suggest that you first try using "openRTSP" as a client, to record 
the incoming stream as a (Transport Stream) file - that you can 
examine and try playing.

If you plan to have only a single client, then you should probably 
stream via unicast rather than via multicast.

You can easily modify the "testOnDemandRTSPServer" demo application 
to stream from your named pipe via unicast: See
