...directly invoking the negotiationneeded event's handler. getting it right was tricky at best, and was so easy to get wrong that bugs are common. using restartice() now, you can use restartice() to do this much more cleanly: pc.onnegotiationneeded = async options => { await pc.setlocaldescription(await pc.createoffer(options)); signaler.send({ description: pc.localdescription }); }; pc.oniceconnectionstatechange = () => { if (pc.iceconnectionstate === "failed") { pc.restartice(); } }; with this improved technique, instead of directly calling onnegotiationneeded with options to trigger ice restart, the failed ice connection state simply calls restartice(). restartice() tells the ice layer to automatically add the icerestart flag to the next ice message sent. problem solved! rollback no longer su...
