Kurento结果返回空值。
Kurento结果返回空值。
提问于 2015-09-27 10:44:27
我从localhost运行一个hello-world客户机示例。
Kurento媒体服务器安装在Amazon实例上。打开所有TCP和UDP端口。对于kurento，google服务器是配置的，亚马逊的公共IP被分配给HttpEndPoint (宣布的IP)，我设法建立套接字连接和交换iceCandidates。
UPDATE服务器在WebRtcEnpoint.conf.ini中配置如下: stunServerAddress=stun.1.google.com stunServerPort=19302
在写这篇文章的时候，这种眩晕似乎很好。
最后两个帧总是这样返回：
{"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}}所以这个值总是空的。

您的KMS没有生成眩晕候选，从这个框架中可以看到。

Sidenote：HttpEndPoint配置不影响WebRTC功能
编辑1
您正在使用CNAME在您的眩晕配置，这是不支持的。请阅读有关如何配置KMS以使用STUN/TURN的文档的这部分。应该是这样的
stunServerAddress=173.194.66.127
stunServerPort=19302确保您使用的服务器正常工作。你可能需要检查其中几个。
