在本地Adobe Media Server上播放视频

Question

我安装了Adobe Media Server 5（入门版）并在Windows 7 上运行

我在服务器上有一个HelloWorld应用程序，还有一个连接到它的客户端闪存文件

现在我想修改这个应用程序来流式传输我放在服务器上的视频

为了实现这一点，我写了一些代码，并粘贴在下面。重要位在netConnectionHandler函数下。

我发布的NetStream现在给了我一个StreamNotFound错误

我的视频路径是

C:Program FilesAdobeAdobe Media Server 5applicationsHelloWorldsample.mp4

nc.connect服务器路径为rtmp://localhost/HelloWorld

我按照这些官方指示来做这件事，但我无法让它发挥作用。

当按照下面的方式执行ns.play时，我会得到一个SteamNotFound错误。然而，如果我输入ns.play("sample")，我会得到：

ns event.info.code: NetStream.Play.Start
ReferenceError: Error #1069: Property onMetaData not found on flash.net.NetStream and there is no default value.

您的问题可能是url的格式。

ns.play("rtmp://localhost/HelloWorld/media/sample.flv");

此命令告诉Adobe Media Server加载名为media的HelloWorld应用程序实例在Adobe媒体服务器中，连接时不会传入任何媒体路径。它在流文件夹中查找传递的媒体。您还可以使用Application.xml文件（或主配置文件）添加其他目录来查找介质。

最简单的方法是将媒体文件夹重命名为"流"。然后像这样连接：

ns.play("rtmp://localhost/HelloWorld/sample.flv");

去掉.flv也应该很好。您可能需要在流文件夹中创建一个名为_definst_的子文件夹，并将您的媒体放入其中。

如果它仍然不起作用，那么您的Application.xml.可能有问题

请尝试在应用程序目录中创建Application.xml文件。使用以下内容：

<Application> 
    <StreamManager> 
        <VirtualDirectory> 
            <!-- Specifies application specific virtual directory mapping for recorded 
            streams.   --> 
            <Streams>/;C:Program FilesAdobeAdobe Media Server 5applicationsHelloWorld</Streams> 
        </VirtualDirectory> 
    </StreamManager> 
</Application>
