doEventLoop() is used to wait for both RTSP responses and incoming RTP
packets. So there is a bug where for example you issue a seek request,
and while waiting for the PAUSE response a packet is received, which
causes the module to think that the PAUSE response came back with an
error; then if another RTSP request is sent right away, the original
PAUSE response while be processed as the response to the second request.
And so on.

Okay, I can fix the problem.
