Yes, and this probably does, indeed, violate the RTSP specification. 
I originally made "fCSeq" a static variable because I was worried 
about a server possibly getting confused if the same CSeq value were 
used by two separate requests from the same client host using the 
same URL - something that could happen if fCSeq were made a 
(non-static) member variable.  (Note my comment in 
"liveMedia/include/RTSPClient.hh")  In practice, however, this is 
probably not going to be a problem for most servers (because each 
request would use a separate TCP connection).  Therefore, because we 
have now seen a server that - instead - has problems with the current 
implementation, I'll change it in the next release of the software.
