on reinvite setLocalDescription happening before addtrack

[Metehan Metin]

Hello

I am trying to implement renegotiation with reinvite.

1 - starting an audio call

2- adding video stream to rtcpeerconnection and calling renegotiate.

3- after calling renegotiate the invite is going with video SDP

4- on the answerer side, I am binding to the reinvite event. Reinvite is triggering when I get the reinvite.

5- In the reinvite, I want to add a video track of the answerer.It is happening but before I add the video track. API is handling setlocaldescription and sending 200 okay.

How can I prevent this? Am I doing something wrong?

->reinvite part of RTCSession.js

      this.emit('reinvite', data);

   .

.

.

        this._connectionPromiseQueue = this._connectionPromiseQueue.then(function () {

          return _this14._createLocalDescription('offer', _this14._rtcOfferConstraints);

        }).then(function (sdp) {

          sendAnswer.call(_this14, sdp);

        })["catch"](function () {

          request.reply(500);

        });

        return;

      }
