在Cordova Android上建立会话后，OpenTok无法添加订户视频

Question

问题

建立OpenTok会话后，设备的订户视频未添加到dom元素。

预期行为

OpenTok session收到streamCreated事件后：

• 将会话订阅到event.stream，
• 传入目标dom元素，
• 提供订户的属性，以及
• 提供回调

应该初始化订阅者流，并用视频流填充提供的dom元素；如果在订阅过程中发生错误，则失败。

this.session.on({
    streamCreated: event => {
        console.log('----- Event Stream: ', event.stream);

        let subscriberProperties = {
            width: '100%',
            height: '100%',
            insertMode: 'append'
        };

        this.subscriber = this.session.subscribe(event.stream, 'subscriberContainer', subscriberProperties, err => {
            if (err) {
                console.log('----- Subscriber subscribe error: ', err);
            }
            else {
                console.log('----- Subscriber added.....');
            }
        });
    }
});

实际行为

streamCreated触发并创建流。OpenTok发出警告：

RTCIceServer.url is deprecated, please use RTCIceServer.urls instead.

其次是这些错误：

订阅错误返回为：

}

网络和设备上的发布者都发送传出的流并正确建立。Web订户正确地从设备接收流并建立。设备订户不接收该流，错误并从未建立。

笔记

流出的流很好。建立两个发布者流，并建立Web门户端的订阅流。传入订阅流永远不会在设备上建立。
