<div>I tried to solve the problem, and got the following results (I have dll library with live555 code and host application that used this library):</div><div>- I have no media sessions, launch and run empty server. Start and stop are OK. Media::close(rtspServer) runs with no errors. Next server starts also OK.</div>
<div>- I have one or more media sessions (from camera stream). First launch is OK. Players (vlc for example) are connected to proxy and played successfully. If we have no clients and try call Medium::close for rtsp server, there is exception in RTCP.cpp:240 (2012.11.22 version). Callstack:</div>
