Hi,
Thanks again, that's very helpful.
One remaining issue, the 'getRTPSinkandRTCP' method in returns *const*
pointers, but the RTPSink member 'getTotalBitrate' is not a const method, so
can't be called from these pointers.
Is there any reason these are const? I see the comment in the header about not
starting or stopping from these pointers, which I guess could be the reason?
Thanks as ever.

First, you don’t do anything with the “RTSPClientConnection” objects; those
represent only the TCP connections that clients use to send RTSP commands.
What you need are the “RTSPClientSession” objects.
If you haven’t already done so, you will need to subclass “RTSPClientSession”,
then, in a member function of your subclass (because this code accesses
‘protected’ member variables), do:
for (unsigned i = 0; i < fNumStreamStates; ++i) {
RTPSink const* rtpSink;
RTCPInstance const* rtcpInstance; // not used
getRTPSinkandRTCP(fStreamStates[i].streamToken, rtpSink,
rtcpInstance);
if (rtpSink != NULL) {
// There are several functions you can call on
“rtpSink” to get data transmission stats:
// packetCount(): the total number of RTP packets
sent
// octetCount(): the total number of ‘payload’
bytes sent - i.e., not including RTP headers
// Note that these two functions return 32-bit
integers, so they will often wrap around
// You can also call:
// getTotalBitrate() (see
“liveMedia/include/RTPSink.hh”), which returns the total amount of data that
was sent (including RTP
// headers, but not IP and UDP headers)
since the last time that function was called. (This also returns the time that
has
// elapsed since then, so you can divide
the count by the time to get a bitrate in bytes-per-second.)
}
