linux - 通过 Internet 访问托管在 AWS 上的 RTSP 服务器

Question

我正在尝试使用 gaminganywhere (gaminganywhere.org) 从 AWS 访问我的 EC2 Ubuntu 实例。安全组策略是允许所有连接，但无法连接到服务器。这是来自客户端和服务器的日志。

我认为 RTSP header 中的 IP 地址是导致连接失败的设备的 LAN IP。同样的软件在 LAN 上运行良好。感谢您的帮助。

Answer 1

如果您在 NAT 后面，gaminganywhere 客户端可能收不到流。

碰巧，这周我尝试了同样的事情。我在 EC2 实例上设置了一个 gaminganywhere 服务器，在我的机器上设置了一个客户端，我观察到了您所描述的确切行为。 (“未收到任何帧...”，DESCRIBE 回复中的私有(private) IP...)。起初我也认为服务器发送的私有(private) IP 是问题所在，但在我的情况下，我没有收到流只是因为我在 NAT 后面。

我尝试用 vlc 打开 RTSP URL，并且......它成功了。在用 wireshark 检查流量后，似乎 VLC 首先要求服务器通过 UDP 发送流，几秒钟后没有 UDP 数据包到达我的机器，它再次请求流，这次请求 TCP。然后 TCP 数据包开始流动，随后发生流式传输。

回到 GA，我找不到强制客户端请求 TCP 的配置选项(编辑:忽略本段)，即使代码似乎允许这样做。所以我在修改代码后编译了客户端，强制使用TCP，这次流式传输成功了。 (我的更改既快又脏:我在调用 rtspClient->sendSetupCommand() 之前在 rtspclient.cpp 中添加了 rtpOverTCP = true。 )

编辑:在更仔细地检查代码后，服务器配置中定义的 core.proto 应该在客户端配置中。我无法测试，但在客户端配置中添加 core.proto = tcp 应该可以。

(注意:gaminganywhere 的变更日志中提到了“NAT 打洞”功能。不确定它是什么或是否有帮助。)
