Playing my own stream in the conference room

[dmitry027]

Greetings everyone,

I have an issue with playing my own stream from remote server in the conference room. It can be reproduced using the demo conference file from AMS distribution (LiveApp/conference.html) with small modifications. I am doing the following:

1. Add the following line in the "publish_started" callback of conference.html file:

// Try to play my own stream from remote server once I started publishing it
webRTCAdaptor.play(obj.streamId, token, roomNameBox.value);

2. Open demo page and click "Join room" button to start publishing my stream to the room

What I expect:
I see additional video element with my stream from the remote server

What I get:
Alert with message "notSetRemoteDescription" and error message in the console:

webrtc_adaptor.js:908 set remote description is failed with error: InvalidAccessError: 
Failed to execute 'setRemoteDescription' on 'RTCPeerConnection': 
Failed to set remote offer sdp: The order of m-lines in subsequent offer doesn't match order from previous offer/answer.

Ant Media version is 2.4.3

Can you confirm why you want another player with your stream twice? It would mean every user in the conference will be seen twice? You can create a new manual stream alongside your conference and load it: webRTCAdaptor.play("new-stream-id", token, roomNameBox.value);

Thank you for the answer. My motivation is to let publisher see his/her own stream as it comes from the server (not directly from the webcam) for diagnostic purpose, so publisher can know how others see/hear him/her.
