All

I am having problems getting the C# version of the WebRtc SendRecv example to work.

I can see both peers connecting to the signaling server and message exchanges taking place but no audio/video ever gets transmitted to the browser.

I believe the issue comes down to the ICE candidate message being sent from the browser, please see the log entries below (they are consecutive).

0:00:01.319596700 38484   05E13C30 LOG                webrtcbin gstwebrtcbin.c:2993:_add_ice_candidate:<sendrecv> adding ICE candidate with mline:0, a=candidate:2589271750 1 udp 2113937151 9228adfe-2557-45a9-bd35-679d37fe1234.local 49755 typ host generation 0 ufrag +uGI network-cost 999

I am using GStreamer V 1.16.2 and GstSharp V 1.16.0.  The OS is Windows 10 64 bit.  All the software is running on a single machine using localhost.  Log Level set to *:3,webrtc*:9,dtls*:9

Very grateful for any help or assistance.

Kind Regards

Jon
