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. | |||
