what is the connection-id for dtlssrtpenc?

[Andres Gonzalez]

Thank you for your response Sebastian. However, your explanation is only
applicable when GStreamer is both the sender and the receiver. In this case,
it is easy to use any value for the connection-id as long as they are
consistent at both GStreamer dtlssrtpenc and dtlssrtpdec.

But if GStreamer is only being used as the sender, I need to ensure the
connection-id is consistent with what the other receiving endpoint is using
so the DTLS handshake is successful.  I am trying to use GStreamer to
connect to a WebRTC client. The WebRTC browser client is initiating a DTLS
handshake with my server which is using GStreamer.  

I have looked at RFC6347 which defines DTLS, but I cannot find any reference
to a "connection-id" the GStreamer dtlssrtpenc/dtlssrtpdec uses. So I am
unsure of how to map the DTLS attributes/properties used in the WebRTC world
to the DTLS attributes/properties used in the GStreamer DTLS world so the
DTLS handshake is successful.

Thanks,
-Andres
