webkitPeerConnection を webkitPeerConnection00 に変更した後、webrtc アプリでピア接続を作成できません

onSignalingMessage が呼び出されない理由

 pc = new webkitPeerConnection00(stun, onSignalingMessage);

ここにコードがあります

webkitPeerConnection00は現在JSEPを使用しています---- そのため、シグナリング メッセージの代わりにice-candidatesを渡します:

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

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