WebRTC无法添加ICE候选人 [英] WebRTC The ICE candidate could not be added

问题描述

我正在尝试与两个对等方建立p2p音频/视频连接。以下： WebRTC入门。

I am trying to establish a p2p audio/video connection b/w two peers. Following: Getting started with WebRTC.

它可以在2台电脑之间的局域网环境中正常工作，但在我公司的局域网环境中运行
时会抛出错误信息，部分是javascript

It works fine at my home in LAN Environment between 2 PCs, but throws an error message when running at my company's LAN Environment, there is part the javascript

function processSignalingMessage(message) {
        var msg = JSON.parse(message);

        if (msg.type === 'offer') {
            // Callee creates PeerConnection
            if (!initiator && !started)
                maybeStart();

            // We only know JSEP version after createPeerConnection().
            if (isRTCPeerConnection)
                pc.setRemoteDescription(new RTCSessionDescription(msg));
            else
                pc.setRemoteDescription(pc.SDP_OFFER,
                        new SessionDescription(msg.sdp));

            doAnswer();
        } else if (msg.type === 'answer' && started) {
            pc.setRemoteDescription(new RTCSessionDescription(msg));
        } else if (msg.type === 'candidate' && started) {
            var candidate = new RTCIceCandidate({
                sdpMLineIndex : msg.label,
                candidate : msg.candidate
            });
            pc.addIceCandidate(candidate);
        } else if (msg.type === 'bye' && started) {
            onRemoteHangup();
        }
    }

当第一个用户收到消息type时：候选人，出错了

when the first user recieved message "type":"candidate",get wrong

和部分控制台日志：

• 创建PeerConnection


• 使用config{iceServers创建了webkitRTCPeerConnnection：[{url：stun：stun.l.google.com：19302}]}


• 添加本地流


• 向同行发送答案


• 收到的消息：{type：candidate，label ：0，id：audio，candidate：a =候选人：1613033416 1 udp 2113937151 192.168.1.233 56946 typ host generation 0 \\ n}


• Uncaught SyntaxError：无法在'RTCPeerConnection'上执行'addIceCandidate'：无法添加ICE候选人


• 收到的消息：{type：candidat...... 。}


• 未捕获的SyntaxError：无法在'RTCPeerConnection'上执行'addIceCandidate'：无法添加ICE候选者


• 收到的消息：{键入 ： candidat .... ...}


• 未捕获的SyntaxError：无法在'RTCPeerConnection'上执行'addIceCandidate'：无法添加ICE候选项

• Creating PeerConnection
• Created webkitRTCPeerConnnection with config "{"iceServers":[{"url":"stun:stun.l.google.com:19302"}]}"
• Adding local stream
• Sending answer to peer
• recieved message : {"type":"candidate","label":0,"id":"audio","candidate":"a=candidate:1613033416 1 udp 2113937151 192.168.1.233 56946 typ host generation 0\r\n"}
• Uncaught SyntaxError: Failed to execute 'addIceCandidate' on 'RTCPeerConnection': The ICE candidate could not be added
• recieved message : {"type":"candidat".......}
• Uncaught SyntaxError: Failed to execute 'addIceCandidate' on 'RTCPeerConnection': The ICE candidate could not be added
• recieved message : {"type":"candidat".......}
• Uncaught SyntaxError: Failed to execute 'addIceCandidate' on 'RTCPeerConnection': The ICE candidate could not be added

推荐答案

我认为你可以只使用msg.candidate创建ICE候选消息，

I think you can create the ICE candidate message by using just the msg.candidate,

var candidate = new RTCIceCandidate(msg.candidate);

并将其传递到 addIceCandidate 函数
