[Live-devel] open session ciclically

Hi Ross,

many thanks for your fast reply.

I have already tried not to send OPTIONS at all, but it fails to create 
a new session, also caching SDP from the first session. On the other 
side I do expect that closing the session, it should open a new one, and 
a new TCP socket on the RTSP socket. That's does not happend, I have 
checked the opened ports too: no more ports opened after the teardown.

All the rtsp commands try probably to go to the old closed session.

Here some details - if you have the patience to give me some more help...

I have registered a delayed task ("this" of RTSPCamera, part of our 
application):
	timerToken = scheduler->scheduleDelayedTask(10000000, timerTask, this);

That is:
void RTSPCamera::timerTask(void *data) {
   RTSPCamera *rtspCamera = (RTSPCamera*) data;
   rtspCamera->rtspClient->teardownMediaSession(*rtspCamera->session);
}

the bye handler that get invoked, shuts down the sessions and tries to 
restart:

void RTSPCamera::SubsessionByeHandler(void *data) {
	RTSPCamera *rtspCamera = (RTSPCamera*) data;

	Medium::close(rtspCamera->subsession->sink);
	rtspCamera->subsession->sink=0;
	Medium::close(rtspCamera->session);
	rtspCamera->start();
}

Where the start() method contains all the needed steps: OPTIONS, SDP, 
Sesion::CreateNew.... and is the method called to start the first session.

When start() issues the firts RTSP command, it fails, and 
env->getResultMsg() returns:
"No such file or directory"

Should it be correct, or am I doing something absolutely wrong?

Yes, our workaround is like this in this moment, but for our context we 
need it to be a self contained executable as much as possible, in order 
to minimize the gap between the streams.

Many thanks again.

Regards,
