Kurento在结果中返回空值

我正在从本地主机运行hello-world客户端示例。
Kurento媒体服务器安装在Amazon EC2实例上。所有TCP和UDP端口都打开。对于kurento谷歌STUN服务器配置和公共IP从亚马逊分配给HttpEndPoint（公布IP）我管理建立套接字连接和交换iceCandidates。Kurento在结果中返回空值

UPDATE STUN服务器在WebRtcEnpoint.conf.ini配置是这样的：stunServerAddress = stun.1.google.com stunServerPort = 19302

在这个STUN似乎做工精细这篇文章的时间。

最后两帧总是返回这样的：

{"id":26,"jsonrpc":"2.0","result":{"sessionId":"4b9642c4-5d42-41e0-ba61-83698b85552f","value":null}} 

{"id":27,"jsonrpc":"2.0","result":{"sessionId":"4b9642c4-5d42-41e0-ba61-83698b85552f","value":null}}

所以该值始终为空。

这里是帧的交换的完整列表：

这意味着，无论你的STUN配置不正确，或者配置的STUN服务器不工作。您可以看看这个公共STUN服务器的这个list，并记住您只能在您的KMS配置中使用IP，因为libnice不接受CNAME。

旁注：HttpEndPoint配置没有在WebRTC功能

编辑1

在STUN的配置，这是不支持任何影响您正在使用的CNAME。请阅读this关于如何配置KMS以使用STUN/TURN的部分文档。它应该是这样的

stunServerAddress=173.194.66.127 
stunServerPort=19302

确保您使用的服务器正在工作。您可能需要检查其中的几个。

嗨@igracia和谢谢你的评论。我使用STUN配置编辑了我的问题，并遵循Kurento教程。此服务器根据您引用的工具工作。谢谢。 –

您的STUN配置不正确，因为只有IP可以使用。检查更新的答案，并按照文档链接查找更多信息 – igracia

@OlegMezhv你有没有检查过？它解决了吗？ – igracia
