Kurent RTSP 和 WebRTC

Question

我正在使用三星的 TOAST 和 Caph-angular 开发三星智能电视应用程序。我在 Windows 10.

当我调用我们的服务器时，我得到一个用 H264 编码的 RSRP url，但在智能电视上，RSRP 不受支持。然后我必须 "transform" RSRP url 到一些 webRTC 之一（我对这一切知之甚少，如果条款不正确，请见谅）。

到处找了一下，发现Kurento似乎能满足我的需求。

在我的应用程序中试用 Kurento 之前，我想在几个演示中对其进行测试。我能够毫无问题地测试 one2many 示例，但我遇到了问题运行ning rtsp2webrtc demo。

我 git 克隆了 kms-windows 和 https://github.com/lulop-k/kurento-rtsp2webrtc 并尝试运行演示，但播放器没有显示任何内容。

1）我双击kms-windows\bin\kurento-media-server

2) 我在 kurento-rtsp2webrtc 中启动 http-server

3) 我到达 http://localhost:8080/，输入我的样本 rtsp url (rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov) 然后点击"start"

似乎没有发生错误，请查看控制台日志：

但是播放器没有任何显示。我仍然看到微调器。

我尝试添加一个 STUN 服务器（不确定它是什么，或者我是否需要一个，只是在文档或其他 Whosebug 问题中看到这个）但它没有解决任何问题。

你能帮帮我吗？我做错了什么或忘记了什么吗？而且，将来，当我想在我的电视网络应用程序中实现它时，我只需要包含 kurento-client.js 和 kurento-utils.js 文件，还是会有其他事情需要处理？

提前致谢

Answer 1

Stun 服务器无法穿越对称 NAT，因此如果您的服务器位于 NAT 之后，那么您应该尝试使用 TURN 服务器

Answer 2

如果你的 Kurento 服务器在 NAT 后面 - 你需要使用 TURN 服务器
