[Live-devel] Getting jitter value

[Ayik Ahmet]

Hello, thank you for responses they helped me a lot. However I came up with a new question. I would like to get number of clients. It works partially okay, For example, when I connect new client, I can see this increment suddenly, when I disconnect client I see effect after 10-20 seconds. Lets say still acceptable. But when there is no client I get random values. I assume it is because there is no RTPSink alive anymore. and I could not find anyway to check if my created RTPSink is alive. I m storing its pointer but when there is no client, it is neither valid nor null, So I cant determine status if RTPSink.

Thanks In Advance
Ozgur Ayik

I think you’re misunderstanding the meaning of the "transmissionStatsDB()” function.  It’s not used to create an object; instead, it simply returns a reference to an object that already exists.  I.e., you can just do something like:
        RTPTransmissionStatsDB& db = myRTPSink->transmissionStatsDB();
        RTPTransmissionStatsDB::iterator iter(db);
        while ((RTPTransmissionStats* stats = iter.next()) != NULL) {
                unsigned jitter = stats->jitter(); // etc.
        }
