Hi Ravi, Yes, that is mean jitter, but it seems you are using 0.8.0, no standard deviation jitter calculation in that version. If you work with the latest SVN source, you will get both calculations: mean jitter & standard deviation, even some report blocks of RTCP XR are already implemented (stats summary is one of them).
