因此，RTCPeerConnection在Edge中启动，用于与Kurento Media Server通信。报价是由js客户端生成的，收到的答案和ICE候选人也被交换。日志是：

问题是流最终开始“流”（其他同伴可以听到音频或观看视频），但是直到事件发生时才开始：
oniceconnectionstatechange: completed
这比连接事件晚21秒。有时会持续30秒。问题是：如何在iceConnectionState =='connected'之后强制RTCPeerConnection开始流式传输
这仅在Edge中发生。 Chrome / FF / Safari中相同的代码和配置可以立即运行
