iOS SDK Conference Mode Issue

[Yury Grinenko]

Hi guys!

I'm developing conference mode based on current version of AntMedia SDK for iOS. I've implemented the flow from this article, it's pretty straightforward. 

As I understand, each participant should start publishing his own stream, and at the same time play remote streams of other participants in the room.

I'm currently performing tests with two participants in the room. It works well if only one participant publishes his stream - the second participant can see and hear stream data. If the second participant also starts publishing his stream, the first participant receives "streamJoined" message, RTCPeerConnectionDelegate's function

`func peerConnection(_ peerConnection: RTCPeerConnection, didAdd stream: RTCMediaStream)` 

is called as well, and after that the webrtc connection disconnects on his side without any error.

I have attached server logs of such call. It contains "i.a.e.adaptive.WebRTCEncoderAdaptor - onIceConnectionChange DISCONNECTED for streamId ..." on line 91. 

We are using "Enterprise Edition 1.9.1" on the server side. On the client side, I've just added commands to join/leave room, publish/play streams, and the `takeCandidate`/`takeConfiguration` part right now is the same as for p2p calls.

Could you please help me to figure out what is the problem here?

Thanks!

It's because iOS SDK does not support multiple streams out of the box. When new one joins it rewrites the old WebRTCClient closing connection. You need to use multiple WebRTCClient (one per each stream in the room)

Hello, Mark!

Thanks for quick response. I'll rewrite code with multiple `WebRTCClient` instances, hope it will solve the problem.

You're welcome! You can take clues from javascript's code for WebRTCAdaptor and code in conference.html.
