streaming two input device requires some changes in live555class #6

Hi According to previous problem in streaming two input device via different threads , if I want to create multiple rtsp server , because of define static variable eventtriggerId , abort occured in env->taskScheduler().doEventLoop(&Stop_RTSP_Loop); I search problem that it must be change static definition of eventtriggerId to non-static. but I do not know how to change this code in FFMPEGClass : Tmp_Head_Node->task->triggerEvent(AnalyserSource::eventTriggerId, Tmp_Head_Node->source); and how to change this line of code in AnalyserSource constructor: if (eventTriggerId == 0) { eventTriggerId = envir().taskScheduler().createEventTrigger(deliverFrame0); } Could you help me ? Thanks

I think you may be confusing multiple RTSP streams within the same instance of Live555 with separate Live555 instances with one stream each.

Live555 lies within a class meaning that even static variables are "local" to that class. If you create another instance of the class it will create another static variable within the class.

I will look into it eventually. If you have any Live555 specific questions you should ask the Live555 guys (http://www.live555.com/), this project simply uses their examples.

I have looked at the code and you were correct, there is indeed issues with variables being static outside of the classes which is stopping multiple instances of Live555 working.

"AnalyserSource::eventTriggerId" is just one of many issues. It is going to take some time to fix unfortunately. The "AnalyserSource::eventTriggerId" issue is not too bad to fix but the others are much harder to fix and it may take some time to get something stable working.

Hi thanks for your answers which of these approaches is true ? multiple RTSP streams within the same instance of Live555 or separate Live555 instances with one stream each ?

Is it possible to use one rtsp server in this project but create multiple ffmpeg class for each input device ? so I create multiple ffmpeg instance and then create a rtsp server that communicate weach of them ? Could you help me for a simple solution for this purpose ? Thanks for your attention

In our case, the code is orientated in the direction of "separate Live555 instances with one stream each"

Yes it is possible to use one RTSP server but I feel the code would need a fair bit of rework to make it easy to use. A singleton may be the best course of action for the Live555 class.

At the moment I don't have much to spend on development of this project so progress will be a little slow.

I do plan on making the class capable of streaming multiple streams in the future.

Hi ahmadi219, 

Have you get a solution to create several streams communicate with a RTSP server? I also run into the issue now.

I changed the eventTriggerId to an non-satic variable, and make the *rtspSever and *env to static variable. but it didn't works.

Thanks for your attention.
