Hi,
I can't pass a non-const pointer into getRTPSinkandRTCP as it will fail to
compile:
error: no matching function for call to
‘ServerMediaSubsession::getRTPSinkandRTCP(void*&, RTPSink*&, const
RTCPInstance*&)’
fStreamStates[count].subsession->getRTPSinkandRTCP(fStreamStates[count].streamToken,
Sink, Instance);
^
note: candidate is:
ServerMediaSubsession::getRTPSinkandRTCP(void*, const RTPSink*&, const
RTCPInstance*&)
I've worked around it at the moment by using a const_cast on the returned
RTPSink pointer to remove the 'const'-ness of it. This isn't ideal though.

Correct. “getTotalBitrate()” modifies the state of the object (to reset the
‘last called time’ and counter), so it can’t be const.
So, in the pseudo code I included in my last email, the declaration of
“rtpSink” should have been
RTPSink* rtpSink;
(at least, if you want to call “getTotalBitrate()”
