Hello, 

please forgive my lack of experience in C++ but it seems that I have some 
problem writing
the code. 
First of all, I am in the RTPSink.cpp file in the 
RTPTransmissionStats::noteIncomingRR 
function and I am trying to write the code which will call the stop() function 
in order 
to open and play another file. 

If the sink->stopPlaying() command is the command I should put in the code, how 
am I 
going to do that since I am in the RTPTransmissionStats object and I want to 
call another
object's method (MediaSink::stopPlaying()) ?

I have noticed that MediaSink class is an  "abstract base class" and that 
stopPlaying() is
a "virtual" function. Does this mean that there exists some other class which 
inherints 
MediaSink and implements the virtual stopPlaying()  ?


I have also noticed that in the OnDemandServerMediaSubsession.cpp, in the 
StreamState::pause() there is an fRTPSink pointer which calls an object's 
stopPlaying()
function. Does the fRTPSink->stopPlaying is the command I am looking for ?


Thanks for your time and for your help
Best regards
kostas
