无法使用Live555服务器流式传输 - 示例不起作用

Question

最近，我从其网站下载了Live555服务器源代码。我试图编译并运行 testMPEG1or2AudioVideoStreamer.cpp 文件中的文件 testProgs 目录。我成功编写了整个项目，包括测试程序。然后我运行 testMPEG1or2AudioVideoStreamer 测试程序。我也放了一个 test.mpg 在测试程序中定义的当前目录中的文件。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.,

然后我复制并播放URL rtsp://192.168.2.22:5555/testStream 使用VLC Media Player，但是VLC只需等待一段时间，然后停止（与Gnome Mplayer也一样）。它不会播放任何音频或视频。任何帮助都将受到赞赏，因为如果没有使用Live555成功流式传输，我将无法前进。这是 testMPEG1or2AudioVideoStreamer.cpp. 。你能告诉我我想念什么...

编辑2： 端口检查

我使用Zenmap扫描端口，并显示5555作为TCP端口，并将其显示为开放。但它显示了该应用程序为Freeciv，但我还没有在系统上安装该游戏。可能是Zenmap的猜测。我在系统上使用Gnome 3.2运行Fedora 16。

一切似乎都还可以，除了以下两个错误：

和

Answer 1

我怀疑这可能与使用非标准端口号有关，但我可能错了。 IANA分配的RTSP端口为554，为次级IIRC为8554。

看起来您在服务器上修改了Live555代码以使用5555。但是，您不知道VLC是否使用非标准RTSP端口号来支持LIVE555。我想您可以在VLC代码中查找此问题。

您可以尝试的事情：

• 使用URI使用OpenRTSP工作
• 使用数据包嗅探器查看网络上实际发生的事情，即使用了哪些端口。
• 使用标准端口，看看是否有效

这些步骤将使您可以缩小问题所在的位置。

编辑：

在RTSP通讯中，您可以看到VLC正在尝试创建单播会话，服务器通过多播运输地址做出响应。然后VLC播放流，没有收到10s的数据，然后尝试通过RTSP会话开始交错的RTP，该服务器再次使用多播地址响应，因此RTSP服务器以461响应。

testmpeg1or2audiovideostreamer读取MPEG-1或2个程序流文件（命名为“ Test.mpg”），从该音频和视频基础流中提取，并使用RTP将其传输到多播组239.255.42.42 （对于音频流）和8888/8889（用于视频流）。该程序还具有（可选的）内置RTSP服务器。

您有多个网络接口吗？流量可能会经历错误的界面。您可以使用Wireshark或其他数据包Sniffer进行检查。如果是这样，此邮件线程可能会有所帮助：http://lists.live555.com/pipermail/live-devel/2007-may/006864.html

在我的情况下，禁用虚拟机（在这种情况下为VirtualBox）网络适配器可行。
