Ich implementiere jetzt den Quellcode von WebRTC Samples zu 3 Benutzer Verbindung durch Verwendung von Mesh-Topologie.WebRTC mit 3 Benutzer Verbindung
Allerdings funktioniert mein Code nicht, wie ich dachte, es wäre. Ich denke, ich bin beim Aufruf der Funktion iceCallBack#
fest (# bezieht sich auf Nummer 1, 2, 3), weil das Ausgabeergebnis das gleiche wie das Original ist. Es kann nur 2 Benutzer verbinden.
Ich weiß nicht, wie es richtig zu beheben ist.
Hier einige meiner JavaScript-Code, die ich gearbeitet habe:
var audio2 = document.querySelector('audio#audio2');
var audio3 = document.querySelector('audio#audio3');
var pc1;
var pc2;
var pc3;
function call() {
callButton.disabled = true;
codecSelector.disabled = true;
trace('Starting call');
var servers = null;
var pcConstraints = {
'optional': []
};
pc1 = new RTCPeerConnection(servers, pcConstraints);
trace('Created local peer connection object pc1');
pc1.onicecandidate = iceCallback1;
pc2 = new RTCPeerConnection(servers, pcConstraints);
trace('Created remote peer connection object pc2');
pc2.onicecandidate = iceCallback2;
pc2.onaddstream = gotRemoteStream;
trace('Requesting local stream');
pc3 = new RTCPeerConnection(servers, pcConstraints);
trace('Created remote peer connection object pc2');
pc3.onicecandidate = iceCallback3;
pc3.onaddstream = gotRemoteStream2;
trace('Requesting local stream');
navigator.mediaDevices.getUserMedia({
audio: true,
video: false
})
.then(gotStream)
.catch(function(e) {
alert('getUserMedia() error: ' + e.name);
});
}
//Description of pc1 creating offer to pc2
function gotDescription1(desc) {
desc.sdp = forceChosenAudioCodec(desc.sdp);
trace('Offer from pc1 \n' + desc.sdp);
pc1.setLocalDescription(desc, function() {
pc2.setRemoteDescription(desc, function() {
pc2.createAnswer(gotDescription2, onCreateSessionDescriptionError);
}, onSetSessionDescriptionError);
}, onSetSessionDescriptionError);
}
//Description of pc1 creating offer to pc3
function gotDescription3(desc) {
desc.sdp = forceChosenAudioCodec(desc.sdp);
trace('Offer from pc1 \n' + desc.sdp);
pc1.setLocalDescription(desc, function() {
pc3.setRemoteDescription(desc, function() {
pc3.createAnswer(gotDescription4, onCreateSessionDescriptionError); //Must edit gotDescription4
}, onSetSessionDescriptionError);
}, onSetSessionDescriptionError);
}
//Creating answer from pc2
function gotDescription2(desc) {
desc.sdp = forceChosenAudioCodec(desc.sdp);
pc2.setLocalDescription(desc, function() {
trace('Answer from pc2 \n' + desc.sdp);
pc1.setRemoteDescription(desc, function() {
}, onSetSessionDescriptionError);
}, onSetSessionDescriptionError);
}
//Creating answer from pc3
function gotDescription4(desc) {
desc.sdp = forceChosenAudioCodec(desc.sdp);
pc3.setLocalDescription(desc, function() {
trace('Answer from pc2 \n' + desc.sdp);
pc1.setRemoteDescription(desc, function() {
}, onSetSessionDescriptionError);
}, onSetSessionDescriptionError);
}
function iceCallback1(event) {
if (event.candidate) {
pc2.addIceCandidate(new RTCIceCandidate(event.candidate),
onAddIceCandidateSuccess, onAddIceCandidateError);
pc3.addIceCandidate(new RTCIceCandidate(event.candidate),
onAddIceCandidateSuccess, onAddIceCandidateError);
trace('Local ICE candidate: \n' + event.candidate.candidate);
}
}
function iceCallback2(event) {
if (event.candidate) {
pc1.addIceCandidate(new RTCIceCandidate(event.candidate),
onAddIceCandidateSuccess, onAddIceCandidateError);
pc3.addIceCandidate(new RTCIceCandidate(event.candidate),
onAddIceCandidateSuccess, onAddIceCandidateError);
trace('Remote ICE candidate: \n ' + event.candidate.candidate);
}
}
function iceCallback3(event) {
if (event.candidate) {
pc1.addIceCandidate(new RTCIceCandidate(event.candidate),
onAddIceCandidateSuccess, onAddIceCandidateError);
pc2.addIceCandidate(new RTCIceCandidate(event.candidate),
onAddIceCandidateSuccess, onAddIceCandidateError);
trace('Remote ICE candidate: \n ' + event.candidate.candidate);
}
}

Hinweis: ich mit WebRTC bin neu. Ich könnte irgendwie dumm sein, bitte vergib mir.
Vielen Dank.
Entschuldigung, dies ist keine Debug-Site. Lust auf eine Frage? – jib
Kann 'RTCPeerConnection(). AddIceCandidate()' 2 Mal gleichzeitig verwendet werden? Weil ich möchte, dass es in zwei Richtungen kommuniziert. Zum Beispiel A -> B, C. B -> A, C. C -> A, B –
