When i call SendTransport::Produce, the function never return. Transport::Listener::OnConnect, is never fired.
If i try to debug, I can see that the program is stopped in the file Handler.cpp, in the function SendHandler::Send on line :
webrtc::RtpTransceiverInterface* transceiver = this->pc->AddTransceiver(track);
Lots of thanks to the team, Mediasoup is a really great library.
