使用的浏览器是Chrome ...我有调用者和接收者代码来生成SDP和ICE候选者.我得到调用者代码以生成具有sdpMid = video的正确SDP和ICE候选者但是对于接收器,我得到仅针对sdpMid = audio生成的ICE候选者.

更新:这是更改后接收器的localSessionDescription SDP,如下所示:

我正在创建一对一的webrtc视频聊天室，此代码不起作用，我想知道为什么

function hasUserMedia(){
navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia || navigator.msGetUserMedia;
return !!navigator.getUserMedia; 
}

function hasRTCPeerConnection() {
window.RTCPeerConnection = window.RTCPeerConnection || 
window.webkitRTCPeerConnection || window.mozRTCPeerConnection;
return !!window.RTCPeerConnection;
}



 function startPeerConnection(stream) {
 var configuration = {

    "iceServers": [{ "url": "stun:stun.1.google.com:19302" }]
 };
 yourConnection = new RTCPeerConnection(configuration);
 theirConnection = new webkitRTCPeerConnection(configuration);

 yourConnection.addStream(stream);
 theirConnection.onaddstream = function (e) {
     theirVideo.src = window.URL.createObjectURL(e.stream);
 };


 yourConnection.onicecandidate = function (event) {
    if (event.candidate){

   theirConnection.addIceCandidate(newRTCIceCandidate(event.candidate));
    }
  };

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