"""
This is an attempt at bridging matrix clients into a Jitis meet room via Matrix
video call. It uses hard-coded xml strings overg XMPP BOSH. It can display one
of the streams from the Jitsi bridge until the second lot of SDP comes down and
we set the remote SDP at which point the stream ends. Our video never gets to
the bridge.
Requires:
npm install jquery jsdom
