我正在尝试与Kurento WebRtc服务器共享我的屏幕.但是得到这个错误:

NavigatorUserMediaError {name: "ScreenCaptureError", message: "", constraintName: ""}

使用相同代码的Firefox中没有错误.用于webrtc的约束:

    var constraints = {
        audio: true,
        video: {
            mandatory : {
                chromeMediaSource: 'screen',
                maxWidth: 1920,
                maxHeight: 1080,
                maxFrameRate: 30,
                minFrameRate: 15,
                minAspectRatio: 1.6
            },
            optional: []
        }
    }

    var options = {
           localVideo : video,
           onicecandidate : onIceCandidate,
           mediaConstraints : constraints
    }
    webRtcPeer = new kurentoUtils.WebRtcPeer.WebRtcPeerSendonly(options,function(error) {
       if (error) {
           return console.error(error);
       }
       webRtcPeer.generateOffer(onOfferPresenter);
    });

如何使用chrome和kurento共享我的屏幕？

我正在尝试将视频轨道添加到流中,然后renegotiate()从JsSip 调用.但是,当我从调用者那里做它时工作正常,但是当我从被调用者那里做它时它不起作用(会话终止).我查看了Freeswitch日志,发现了下一行:
