Javascript 节点教程一对多没有加载远程服务器流微调器

我对使用项目中所需的Kurrento还不熟悉，但我克隆了git hub上为Kurento提供的教程，并遵循one2Many调用的说明。首先，我成功解决了adapter.js中的包损坏问题，但之后出现了一个问题，即我的网络摄像头运行良好，我能够看到我的侧流，但无法看到远程流，旋转器无休止地移动。

而且我在chrome的控制台上看到两个错误，即：-

1)Failed to parse SessionDescription. m=audio 0 UDP/TLS/RTP/SAVPF
Expects at least 4 fields. 
2)Uncaught (in promise) Failed to parse
SessionDescription. m=audio 0 UDP/TLS/RTP/SAVPF Expects at least 4 fields.

现在上面的错误已经解决了，我的控制台上没有任何错误

以下是我遵循的步骤-：

1)sudo git clone https://github.com/Kurento/kurento-tutorial-node.git 2)curl -sL https://deb.nodesource.com/setup | sudo bash -  
3)sudo apt-get install -y nodejs  
4)sudo npm install npm -g  
5)cd static 
6)bower install  
7)node server.js

现在，kurento示例在端口号8443上运行

之后，我在chrome浏览器46.0.2490.86版上打开了该URL

之后，我在HelloWorld的例子中看到了say。 屏幕截图位于以下URL中，请检查：-

在消息文本区域，它将显示：-

这是无尽旋转器的快照

这就是我的代码、机器、版本和配置文件

在所有教程示例中，我都面临这个问题

请帮我摆脱这种状况。 任何帮助都将不胜感激。

谢谢

正如我在您的屏幕截图中看到的，您使用的是外部服务器，也就是说，并非所有东西都是本地主机

---

在这种情况下，您可能需要根据网络拓扑配置眩晕/转弯。有关更多信息，请参阅链接。

我在另一台ubuntu机器上安装了kurento，它对我有效，我遵循以下步骤：-

我通过

apt获得dist升级

但是升级dist之前要小心，因为它会升级分发版，之后你的一些应用程序可能无法运行

然后安装

sudo apt get安装libglib2.0-0

之后我安装了kurento

sudo apt get安装kurento-media-server-6.0

之后，我显式安装了openJdk7

最后它对我起了作用。但在那之后，我的一些应用程序无法在我的机器上运行，如skype等，因此当我为那些安装依赖项时，kurento远程侧流问题再次出现，因此最终我从该机器上删除了所有内容，只运行kurento，毫无疑问，这工作正常

---

谢谢，我也有同样的问题。我在8888和8433端口（wss）的docker容器中运行KMS

如果我通过“npm start--ws_uri=ws://192.168.99.100:8888/kurento”来运行这个示例，那么就可以了

但是，如果我用“npm start--ws_uri”运行它=wss://192.168.99.100:8433/kurento“，那么我的问题和你的一样。原因是，在节点应用程序上，我没有强制它接受来自MKS的自签名证书。看

谢谢，

我遇到了同样的问题：控制台记录了“重新连接到服务器…未定义”，浏览器中的流微调器不断移动。幸运的是，我的问题很简单。我忘记在重新启动后使用以下命令运行KMS：

sudo service kurento-media-server-6.0 start

您的配置文件似乎有问题，但您提供的信息很难确定say@santoscadenas谢谢你更快的回复。但正如我所写的，我已经遵循了您在git hub上给出的指示。请让我知道我应该向您展示哪个配置文件，以便我们可以解决这个问题。感谢您的帮助。您能否提供有关kms安装的更多详细信息。您执行了哪些步骤来安装它。从您报告的唯一错误来看，配置文件似乎有问题。如果服务器和客户端位于同一网络中，默认配置足以查看视频，您是否编辑了它们？还将显示有关您正在使用的浏览器的信息helpful@santoscadenas我已经编辑了代码并添加了更多信息。请查看并帮助我找到我做错的地方。谢谢我的回复，如果您提供有关网络拓扑的更多信息，我可以完成它。ie：如果kms或客户端支持NAT。感谢回复，我按照您与我共享的链接中给出的设置了STUN和TURN服务器，但我仍然面临同样的问题。以下是我在WebRtcEndpoint.conf.ini中更改的配置，即stunServerAddress=54.172.47.69 stunServerPort=3478和turnURL=user：password@66.228.45.110：3478所以请告诉我我是以正确的方式进行的，还是我在做配置错误。谢谢你能给我看一下你配置昏迷和转kms的文件吗？更多，你能分享kms日志吗？
