Are you using our software to develop your client?  If not, then we 
can't help you - sorry.

If, however, you are using our software to develop your client, then 
the presentation timestamp for each piece of data read from a 
"RTPSource" object is passed - as a parameter - to the 'after 
getting' function that was previously passed in the call to 
"getNextFrame" on the "RTPSource" object.  (Note the many examples in 
the code.)

>         Whether we have to use RTP timestamp values for this?

No.  Our software automatically calculates the presentation time from 
the RTP timestamps and RTCP reports.  You don't need to calculate 
this yourself - instead, just use the "presentationTime" parameter.
