If you rebuild the entire stack (new TransportLayer instances), then you will cause a new DTLS connection to be created. We don't want that [4]. What you really want is to have two NrIceMediaStream instances active in a single TransportLayerIce, so that you can do a smooth transition between the two. Ideally, you would add both until the second is fully connected, it may be necessary to have a timer on the old one so that you can remove it after it has properly drained. This timer might be short-ish, just to account for the possibility that the new stream is faster than the old one, or you could just decide to accept some packet loss. [4] Until we decide that we want to implement a=dtls-connection support, which I would encourage you to defer as long as possible. _______________________________________________ dev-media mailing list [email protected] https://lists.mozilla.org/listinfo/dev-media
