[Live-devel] How to calculate all packet loss rate?

You can look at the statistics that are reported in incoming RTCP 
"RR" messages (sent by clients; received by the server), and RTCP 
"SR" messages (sent by the server; received by clients).  To do this:
- At the client end, look at "RTPSource::ReceptionStatsDB" and 
"RTPSource::ReceptionStats"
- At the server end, look at "RTPSink::TransmissionStatsDB" and 
"RTPSink::TransmissionStats".

Look, for example, at how "openRTSP" uses the 
"RTPSource::ReceptionStats(DB)" information (to implement its "-Q" 
option).  You can use "RTPSink::TransmissionStats(DB)" in a similar 
way.
