We are using openRTSP Client to receive mpeg2 streams. When we call
PAUSE and then PLAY request during streaming then
we observed function getResponse1() is getting called from two
places simultaneously
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.)
