Add/remove audio track via SDP renegotiate?

[pavlokdbd]

Hi everyone! Currently kvsWebRTCClientMaster/Viewer sample apps reject any subsequent SDP offer in case peer connection had been already established via first SDP offer in samples/Common.c:
case SIGNALING_MESSAGE_TYPE_OFFER:

// Check if we already have an ongoing master session with the same peer

CHK_ERR(!peerConnectionFound, STATUS_INVALID_OPERATION, "Peer connection %s is in progress", pReceivedSignalingMessage->signalingMessage.peerClientId);

Is there a way to support renegotiate via another SDP offer, e.g. so that audio track added or removed?
I have tried to disable the check above and create/send answer for new offer in similar way that it is done in handleOffer(). respondWithAnswer() fails in this case.

Hi @pavlokdbd, renegotiation is not supported yet

How do you recommend to implement audio with later connection when video is already connected? We need this to have a button for audio in the android app to switch audio on during video session. If we create audio track together with video there is a nasty green dot for microphone which informs the user that audio is beibg recorded and being transmitted to the other party, while we don't want this.
