Javascript 未捕获类型错误：peerConnection.addstream不是函数？

我正在尝试附加使用

startPeerConnection（stream）

上的

getusermedia（）

捕获的流。我尝试用以下方式添加流

   function startPeerConnection(stream) {
            var configuration = {
                // Uncomment this code to add custom iceServers    //
                "iceServers": [{ "url": "stun:stun.1.google.com:19302" }]
            };

            yourConnection = new RTCPeerConnection(configuration);
            theirConnection = new RTCPeerConnection(configuration);


            // Setup stream listening 
            yourConnection.addStream(stream);//***getting the error on this line***
            theirConnection.onaddstream = function (e) {
                theirVideo.srcObject = e.stream;
                theirVideo.play();
            };


            // Setup ice handling
            yourConnection.onicecandidate = function (event) {
                if (event.candidate) {
                    theirConnection.addIceCandidate(new RTCIceCandidate(event.candidate));
                }
            };

            theirConnection.onicecandidate = function (event) {
                if (event.candidate) {
                    yourConnection.addIceCandidate(new RTCIceCandidate(event.candidate));
                }
            };



            // Begin the offer 
            yourConnection.createOffer(function (offer) {
                yourConnection.setLocalDescription(offer);
                theirConnection.setRemoteDescription(offer);
                theirConnection.createAnswer(function (offer) {
                    theirConnection.setLocalDescription(offer);
                    yourConnection.setRemoteDescription(offer);
                });
            });
        };

RTPeerConnection如下所示：

var RTCPeerConnection = function(options) {

    var iceServers = options.iceServers || defaults.iceServers;
    var constraints = options.constraints || defaults.constraints;

    var peerConnection = new PeerConnection(iceServers);

    peerConnection.onicecandidate = onicecandidate;
    peerConnection.onaddstream = onaddstream;
    peerConnection.addStream(options.stream);//***getting error on here ***

    function onicecandidate(event) {
        if (!event.candidate || !peerConnection) return;
        if (options.getice) options.getice(event.candidate);
    }

    function onaddstream(event) {
        options.gotstream && options.gotstream(event);
    }

addStream是一个已从标准中删除的方法，Safari没有实现它。 通过替换来切换到addTrack方法

peerConnection.addStream(options.stream);

或者在您的项目中包括哪个polyfills addStream

PeerConnection来自哪里？它不在浏览器标准中。我在这里使用了js文件：嗯。。。您正在用一个同名函数覆盖“像这样”中的RTPeerConnection对象。这是个坏主意……依赖标记为“实验”的github repo（已经6年没有涉及过）对WebRTC来说不是个好主意。它有几个问题，我在本期中也列举了这些问题。hye@jib谢谢你的建议，我在这里尝试了你的演示：它看起来很酷。我只是想知道我们如何为此设置远程连接。如果您能提供帮助，我将不胜感激

options.stream.getTracks().forEach(track => peerConnection.addTrack(track, options.stream))
