webrtc: addTransceiver: demo doesn't work when trying to bypass trickle ICE #86

Closed space88man closed 5 years ago

Previously with addTrack it was possible to bypass trickle ICE.

  1. Disable sending new-ice-candidate or immediately sending video-offer/video-answer
  2. Wait until ICE gathering is complete event.candidate === null; then send video-offer/video-answer; in this case the SDP is fully populated with ICE candidates.

With addTransaction, this no longer works.

My mistake - when trying to stall the SDP(to gather all the ICE candidiates), there is a race condition with the callee-generated video-offer/video-answer round-trip. Still need to look at this closer.
