[Live-devel] Problem in sending PAUSE and then PLAY request in openrtsp

No. Remember that the code is single-threaded.  It is not possible 
for "getResponse1()" - or any other function - to be called from two 
places 'simultaneously'.

What I suspect is happening is that you have requested RTP-over-TCP - 
i.e., using the "-t" command-line option to "openRTSP".  There is 
currently a known bug in the code that - iff you have requested 
RTP-over-TCP - any response to a RTSP command - after the initial 
"PLAY" command(s) - is not read by the RTSP client code.  Therefore, 
iff you have requested RTP-over-TCP, then you currently can't do a 
RTSP "PAUSE" (because you won't then be able to send a subsequent 
"PLAY" to restart the stream).

(With regular, RTP-over-UDP, streaming, there are no known problems 
with sending "PAUSE" (or other) commands during streaming.)
