安卓rtsp通过3g使用外部IP

Question

我正在为我的实习项目开发一个android应用程序，该应用程序是将H264 DVR相机流式传输到android作为客户端。每当我使用Wifi时，我只能使用内部IP 192.xxx.xxx.xxx连接到DVR，logcat说

有人能告诉我我的问题是什么吗？我需要使用套接字、数据包、输入/输出流、缓冲区恐惧器/写入器或任何东西吗？如果是，请给我一些例子，这样我就可以学习如何使用

p.S在真实设备上测试（Elephone P8000 Android 5.0）

注意：这些"xxx"仅用于安全目的

如果没有更多信息和代码，很难确定，但最有可能的问题是您的提供商正在阻止其网络上的这种类型的连接-一些运营商会阻止"上行链路"流媒体流量，要么是为了保持带宽，要么是因为他们可能认为这是一种类似VoIP的服务，与他们的某项服务竞争。

它在WiFi上工作的原因是，很可能你的Android设备和相机都在同一个网络上，它们之间没有防火墙等。
