<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Live555 is working great in our proof of concept (thanks!)…time to move on use in production code, which brings up a question…<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">All example code seems to set up a server and then let it run until the process terminates, without any explicit cleanup.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Suppose in my project I want to start and stop an RTSPServer at designated times, clean up after stopping, with the possibility of re-starting later (on the same port even).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I notice the destructor of RTSPServer class is protected. What is the design goal here? What is the correct method of resource cleanup/recycling given this design?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So far, my only ‘workaround’ is to derive a class of my own from RTSPServer and make the derived class’ destructor public.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Will destruction of the (derived) RTSPServer also clean up (delete) the media sessions registered with it (it appears yes, just want to confirm).
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Anything else that needs to be cleaned up?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can the UsageEnvironment and the TaskScheduler have lifetimes that span many server startups & shutdowns?
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks!<o:p></o:p></p>
<p class="MsoNormal">-Eric.<o:p></o:p></p>
