Question

我使用WebRTC在HTML页面中启用视频共享。当我在本地主机上运行我的HTML页面，并使用两个不同的Mozilla实例进行检查时，它运行正常。但是当我使用远程PC访问它时，视频没有显示。这是我正在使用的代码：

<!DOCTYPE html>
<html>
<head>
<script src="https://www.webrtc-experiment.com/socket.io.js"> </script>
<script src="https://www.webrtc-experiment.com/RTCPeerConnection-v1.5.js"> </script>
<script src="https://www.webrtc-experiment.com/video-conferencing/conference.js"> </script>
</head>

<body>
<P> Press this button to start a new conference:
<button id="setup-new-room">Setup New Conference</button></p>
<table style="width: 100%;" id="rooms-list"></table>
<div id="videos-container"></div>

<script>
    var config = {
        openSocket: function(config) {
            var SIGNALING_SERVER = 'http://webrtc-signaling.jit.su:80/',
            defaultChannel = location.hash.substr(1) || 'video-conferencing-hangout';

            var channel = config.channel || defaultChannel;
            var sender = Math.round(Math.random() * 999999999) + 999999999;

        io.connect(SIGNALING_SERVER).emit('new-channel', {
            channel: channel,
            sender: sender
        });

        var socket = io.connect(SIGNALING_SERVER + channel);
        socket.channel = channel;
        socket.on('connect', function() {
            if (config.callback) config.callback(socket);
        });

        socket.send = function(message) {
            socket.emit('message', {
                sender: sender,
                data: message
            });
        };

        socket.on('message', config.onmessage);
    },
    onRemoteStream: function(media) {
        var video = media.video;
        video.setAttribute('controls', true);
        video.setAttribute('id', media.stream.id);
        videosContainer.insertBefore(video, videosContainer.firstChild);
        video.play();
    },
    onRemoteStreamEnded: function(stream) {
        var video = document.getElementById(stream.id);
        if (video) video.parentNode.removeChild(video);
    },
    onRoomFound: function(room) {
        var alreadyExist = document.querySelector('button[data-broadcaster="' + room.broadcaster + '"]');
        if (alreadyExist) return;

        var tr = document.createElement('tr');
        tr.innerHTML = '<td><strong>' + room.roomName + '</strong> shared a conferencing room with you!</td>' +
                       '<td><button class="join">Join</button></td>';
        roomsList.insertBefore(tr, roomsList.firstChild);

        var joinRoomButton = tr.querySelector('.join');
        joinRoomButton.setAttribute('data-broadcaster', room.broadcaster);
        joinRoomButton.setAttribute('data-roomToken', room.broadcaster);
        joinRoomButton.onclick = function() {
            this.disabled = true;

            var broadcaster = this.getAttribute('data-broadcaster');
            var roomToken = this.getAttribute('data-roomToken');
            captureUserMedia(function() {
                conferenceUI.joinRoom({
                    roomToken: roomToken,
                    joinUser: broadcaster
                });
            });
        };
    }
};

var conferenceUI = conference(config);
var videosContainer = document.getElementById('videos-container') || document.body;
var roomsList = document.getElementById('rooms-list');

document.getElementById('setup-new-room').onclick = function () {
    this.disabled = true;
    captureUserMedia(function () {
        conferenceUI.createRoom({
            roomName: 'Anonymous'
        });
    });
};

function captureUserMedia(callback) {
    var video = document.createElement('video');
    video.setAttribute('autoplay', true);
    video.setAttribute('controls', true);
    videosContainer.insertBefore(video, videosContainer.firstChild);

    getUserMedia({
        video: video,
        onsuccess: function (stream) {
            config.attachStream = stream;
            video.setAttribute('muted', true);
            callback();
        }
    });
}
</script>

我需要更改什么来制作视频节目？

在jsfiddle上尝试相同的演示并且它有效！

实际上信令服务器（socket.io/node.js）'http://webrtc-signaling.jit.su:80/'已停止工作，现已解决！
