Failed ice connection between Edge and Safari with empty MediaStream #81

Steps to reproduce:

  1. Create new MediaStream() in Safari.
  2. Add this stream to connection.
  3. Gather ice candidates.
  4. Send offer with ice candidates to Edge.
  5. Add ice candidates to connection.
  6. Gather ice candidates on Edge side.
  7. Send answer with ice candidates to Safari.
  8. Add ice candidates to connection.

Actual result:
iceConnectionState became 'checking'.
After few seconds iceConnectionState became 'failed'.

Also I tried to create media stream with video and audio. In that case iceConnectionState became connected, but I'd got an error "OperationError (DOM Exception 34): Failed to set local sdp: Session error code: ERROR_CONTENT. Session error description: Failed to set local audio description recv parameters.."

This problem occurred only for Edge - Safari connection.

How does the offer look in step 4? As far as I can see it, pc.addStream(new MediaStream([])) creates an offer like

v=0
o=- 7693327771252956079 2 IN IP4 127.0.0.1
s=-
t=0 0
a=msid-semantic: WMS

which doesn't have any candidates. Note that this offer won't be something Firefox is happy about either.
Also how does the answer from Edge look like?

"OperationError (DOM Exception 34): Failed to set local sdp: Session error code: ERROR_CONTENT. Session error description: Failed to set local audio description recv parameters.."

How do the offer from safari and the answer from Edge look like?

In Firefox we are using new AudioContext().createMediaStreamDestination().stream, but this solution is not very good because of limitations of used streams in audioContext.

Case with error:

  1. Offer from Safari. Stream with audio and video.

Thanks. Are you calling createOffer with ({offerToReceiveAudio: true, offerToReceiveVideo: true})?

The second error seems to be related to the change of offer-answer roles even though it does not make sense for Safari to error in SLD. This might be fixed by #80 but that is not published on npm yet. Will take a look.

Yes, I'm calling with both offerToReceiveAudio and offerToReceiveVideo.

I tried to use this fix, but I've got "Failed to set local sdp: Session error code: ERROR_CONTENT. Session error description: Failed to set remote video description send parameters.." error in chrome. And it didn't fix the problem with an error in Safari.
