5 years ago I read about your issue. I will try today another solution by creating rooms for each stream.
My knowledge about WebRTC is not enough to eliminate this error. Unfortunately I have no time to read in there at the moment.

5 years ago Please use replaceTrack rather than add/remove streams. Same as I'm doing in this demo:
Unified-plan is bringing multi-similar-tracks limitations. That's why please make sure that you're not using multiple video tracks. A solution for such situations can be to setup multiple parallel RTCMultiConnection instances. i.e. one for video and another one for screen.

5 years ago I have this error appears at the moment of Broadcast's connection with the Viewer.
Scenario
setRemoteDescription failed DOMException: Failed to execute 'setRemoteDescription' on 'RTCPeerConnection': Failed to set remote answer sdp: Called in wrong state: kStable v = 0 o = - 2965669704544847005 2 IN IP4 127.0.0.1 s = - t = 0 0 a = msid-semantic: WMS
At the same time, in the Broadcast console, RTCMultiConnection displays the status of the Viewer. And in the viewer console there is also the active Broadcast status. But because of an error, they do not connect.
=========== In order for the Viewer to connect the stream from Broadcaster (I remind you that Broadcastter in my scenario connects to the room after the Viewer) I use the following algorithm:
The initiator opens the room
The viewer connects to the room.
Broadcast last connects to the room.
At Broadcast, the connection.onopen event is triggered.
Broadcaster sends the request to the initiator and receives from it a list of participants connected to the room:
connection.socket.emit (connection.socketCustomEvent, {
giveAllParticipants: true
});Broadcast in the list finds Viewers and sends a connection request to all Viewers using the command:
connection.peers [participant.pid] .addStream ({
audio: true,
video: true,
oneway: true
});
7. After that the Viewer connects to itself broadsters.
Maybe you need to do something differently in order not to use the crutch I described?@muaz-khan Thank you again for your suggestion. The problem is now that the LED from the webcam is on continuously. When we use this in a chat application, users may be uncomfortable that the camera is always on. Is there another solution?
Would be nice if we could get an example how to replace the track for a addStream/removeStream Chat Room ie. Start Webcam -> Remove Webcam -> Start Webcam again without getting into trouble.

5 years ago @VShtaba Good news for you. Solved the problem by creating a queue for adding/removing actions.
The client side is waiting for a callback that there is no adding/removing action currently. The other requests are waiting for previous requests have been handled.

5 years ago Hello. Thank. Are you talking about this decision? https://github.com/mdn/samples-server/issues/57#issuecomment-412468733

5 years ago @VShtaba No... It's a custom solution.
On the clientside you can set 2 custom socket callback events for adding/removing streams.
// Same for adding stream function removeLocalStream() {
connection.socket.emit('waitingRemove', connection.userid, function(response) {
if(response === true) {
connection.extra.broadcastid = "";
connection.updateExtraData();
connection.attachStreams.forEach(function(stream) {
stream.getTracks().forEach(track => track.stop());
stream.getTracks().forEach(track => stream.removeTrack(track));
});
$("#webcamload").addClass("fa-video-camera");
$("#webcamload").removeClass("fa-spinner");
$("#webcamlabel").text("Kamera Aç");
ready = 1;
}
});}
Create a queue (object) on the serverside and check (setInterval - i.e. 1 second interval) if there are streams to add or remove. Handle the requests one by one with callbacks. This should solve the issue.
setInterval(function() {
if(Object.keys(streamQueue).length > 0) {
for(var key in streamQueue) {
streamQueue[key] = 0;
console.log("Queue: " + streamQueue[key]);
break;
}
}}, 1000);
// In io.connection socket.on("waitingRemove", function(userid, fn) {
console.log("Remove requested");
streamQueue[userid] = 1;
ii[userid] = setInterval(function() {
if(streamQueue[userid] == 0 && typeof userlist[userid] != 'undefined' && typeof broadcast[userid] != 'undefined') {
clearInterval(ii[userid]);
delete streamQueue[userid];
console.log("Deleted from queue");
fn(true);
}
else if(typeof userlist[userid] == 'undefined' || typeof broadcast[userid] == 'undefined') {
clearInterval(ii[userid]);
console.log("Couldnt be found");
delete streamQueue[userid];
fn(false);
}
}, 100);
});Thank you, colleague.
I get this error when Broadcaster connects to the Viewer (one-way direction). In this case, an error appears in the Viewer console: "setRemoteDescription failed DOMException: Failed to execute 'setRemoteDescription' on 'RTCPeerConnection': Failed to set remote answer sdp: Called in wrong state: kStable v = 0 o = - 2965669704544847005 2 IN IP4 127.0. 0.1 s = - t = 0 0 a = msid-semantic: WMS " and Broadcast stream does not appear in Viewer.

"Called in wrong state: kStable" is caused by Google Chrome. It sends the request twice Could you fix it please?
Hi Muaz,
thank you for this nice piece of work.
I get the following errors after adding and removing a couple of streams in a chat room for multiple times at the same time (sometimes it's working only once, sometimes i can add/remove streams up to 4-5 times)
