I actually had similar idea, and already added bundles for this purpose at the
first go-round. Here sdparta_0 and sdparta_1 are the "old ones". But anyway
video m-sections has Port 9.
Local SDP (offer)
a=group:BUNDLE sdparta_0 sdparta_1
Remote SDP (answer)
a=group:BUNDLE sdparta_0
a=group:BUNDLE sdparta_1
If it's because correct port is occupied by audio and there's no workaround, it
would be very sad : I would have to modify server transport and it's a lot of
work.
And if a webrtc client would always be an "answer", would it help ?
