Question

我已经使用API Key，Session和Token（针对发布者）为OpenTok设置了一个基本测试页面。基于QuickStart添加了代码以跟踪microphoneLevelChanged事件。页面代码为available here。重要的是：

var apiKey = "API KEY HERE";
var sessionId = "SESSION ID HERE";
var token = "TOKEN HERE";

function sessionConnectedHandler(event) {
    session.publish(publisher);
    subscribeToStreams(event.streams);
} 
function subscribeToStreams(streams) {
    for (var i = 0; i < streams.length; i++) {
        var stream = streams[i];
        if (stream.connection.connectionId != session.connection.connectionId) {
            session.subscribe(stream);
        }
    }
}
function streamCreatedHandler(event) {
    subscribeToStreams(event.streams);
    TB.log("test log stream created: " + event);
}

var pubProps = { reportMicLevels: true };
var publisher = TB.initPublisher(apiKey, null, pubProps);
var session = TB.initSession(sessionId);
session.publish(publisher);

session.addEventListener("sessionConnected", sessionConnectedHandler);
session.addEventListener("streamCreated", streamCreatedHandler);
session.addEventListener("microphoneLevelChanged", microphoneLevelChangedHandler);
session.connect(apiKey, token);

function microphoneLevelChangedHandler(event) {
    TB.log("The microphone level for stream " + event.streamId + " is: " + event.volume);
}

我知道日志记录有效，因为日志显示自streamCreatedHandler。但是，我没有在microphoneLevelChangedHandler函数中记录任何事件。我试过这个，一个和两个客户端加载页面（视频显示得很好）。

我需要做些什么才能显示microphoneLevelChanged个事件？

OpenTok的WebRTC js库没有microphoneLevelChanged事件，所以你无能为力，抱歉。

无法使用OpenTok查看MicrophoneLevel和VolumeEvent会话信息
