Question

将webkitPeerConnection更改为webkitPeerConnection00后，我无法在webrtc应用上创建对等连接

为什么onSignalingMessage没有调用

 pc = new webkitPeerConnection00(stun, onSignalingMessage);

这是代码

$(function(){
var localInfo = {
    video:  $("#video_local").get(0),
    video_remote:  $("#video_remote").get(0),
    stream: null,
    initiator: false,
    peerCon: null,
    started: false,
    uid: render_param.uid,
    readySDP: null
};
wsSend({"act": "list", "join": "1"}, function(data){
    updateRoomDisplay(data.room_list);
    setInterval(function(){
        wsSend({"act": "check"}, function(data){
            $.each(data.ret, function(i, json_str){
                var msg = JSON.parse(json_str)
                if (msg.type == "sdp"){
                    receiveSDP(msg.sdp);
                } else if (msg.type == "room_info"){
                    updateRoomDisplay(msg.room_list);
                }

            });
        });
    }, 3000);
});
function updateRoomDisplay(room_list){
    console.log("list receive", room_list);
    var container = $("#room_container");
    container.empty();
    $.each(room_list, function(i, room_persons){
        if (i > 0){
            var class_add = "";
            if (room_persons == 2){
                class_add = " room_full";
            }

    });

webkitPeerConnection00现在正在使用 JSEP ----因此它会传递 ice-candidate 而不是信令消息：

window.PeerConnection = window.webkitPeerConnection00;
var peer = new PeerConnection(stun, onGettingIceCandidates);

function onGettingIceCandidates(candidate, isLastCandidate)
{
    // candidate.toSdp() ------ and ------ candidate.label
}
