最近我从他们的网站下载了 Live555 服务器源代码。我试图编译和运行testMPEG1or2AudioVideoStreamer.cpp目录中的testProgs文件。我成功编译了整个项目，包括测试程序。然后我运行testMPEG1or2AudioVideoStreamer测试程序。test.mpg我还在测试程序中定义的当前目录中放置了一个文件。运行后我得到以下输出：
Play this stream using the URL "rtsp://192.168.2.22:5555/testStream"
Beginning streaming...
Beginning to read from file...
...done reading from file
Beginning to read from file...
...done reading from file
etc.,
然后我使用 VLC 媒体播放器复制和播放 URL rtsp://192.168.2.22:5555/testStream，但 VLC 只是等待一段时间然后停止（也与 Gnome MPlayer 相同）。它不播放任何音频或视频。感谢您提供任何帮助，因为如果不使用 Live555 成功进行流式传输，我将无法继续前进。这是 的代码testMPEG1or2AudioVideoStreamer.cpp。你能告诉我我错过了什么吗...

我使用 Zenmap 扫描端口，它显示 5555 作为 tcp 端口并打开。但它显示应用程序为freeciv，但我还没有在我的系统上安装那个游戏。可能是 Zenmap 的猜测。我在我的系统上运行带有 gnome 3.2 的 Fedora 16。
