我认为RTSP标头中的IP地址是设备的LAN IP，导致连接失败。相同的软件可以在局域网中正常工作。任何帮助表示赞赏。
答案 0 :(得分：0)
如果您在NAT的后面，gamesanywhere客户端可能不会接收该流。
碰巧的是，本周我尝试了同样的事情。我在EC2实例上设置了gaminganywhere服务器，并在计算机上设置了客户端，并且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IP ...）。起初，我还以为服务器发送的专用IP是问题所在，但是在我的情况下，我之所以没有收到数据流，仅仅是因为我在NAT后面。
我试图用vlc打开RTSP URL，并且...起作用了。在使用Wireshark检查流量之后，似乎VLC首先要求服务器通过UDP发送流，然后在几秒钟内没有UDP数据包到达我的计算机后，它再次询问该流，这次要求TCP。然后，TCP数据包开始流动并随之流化。
回到GA，我发现找不到配置选项（编辑：无视本段）来强制客户端请求TCP，即使代码似乎允许这样做也是如此。因此，在修改代码以强制使用TCP之后，我编译了客户端，这一次流传输成功了。 （我的更改既快速又肮脏：我在rtpOverTCP = true调用之前在rtspclient.cpp中添加了rtspClient->sendSetupCommand()。）
编辑：在仔细检查了代码之后，服务器配置中定义的core.proto应该位于客户端配置中。我无法测试，但是在客户端配置中添加core.proto = tcp应该可以。
（注意：游戏任何地方的变更日志中都提到了“ NAT打孔”功能。不确定它是什么，或者是否有帮助。）
