actionscript-3 - 在本地 Adob​​e Media Server 上播放视频

Question

我在 Windows 7 上启动并运行了 Adob​​e Media Server 5(入门版)

我在服务器上有一个 HelloWorld 应用程序，以及一个连接到它的客户端 flash 文件。

现在我想修改此应用程序以流式传输我放置在服务器上的视频

为了实现这一目标，我编写了一些代码，并将其粘贴在下方。 重要的位在 netConnectionHandler 函数下。

我现在发布的 NetStream 给我一个 StreamNotFound 错误

我的视频路径是

C:\Program Files\Adobe\Adobe Media Server 5\applications\HelloWorld\sample.mp4

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

我正在关注 these official instructions执行此操作，但我无法使其正常工作。

当执行如下所示的 ns.play 时，我收到一个 SteamNotFound 错误。但是，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.

您的问题可能是您的网址格式。

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

这会告诉 Adob​​e Media Server 加载名为 media 的 HelloWorld 应用程序实例 在 Adob​​e 媒体服务器中，您在连接时不会传入任何媒体路径。它会在 streams 文件夹中查找所传递的媒体。您还可以使用 Application.xml 文件(或主配置文件)添加其他目录以查找媒体。

完成这项工作的最简单方法是将您的媒体文件夹重命名为“streams”。然后像这样连接:

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

离开 .flv 应该也能正常工作。您可能需要在名为 _definst_ 的流文件夹中创建一个子文件夹，并将您的媒体放入其中。

如果它仍然不起作用，您的 Application.xml 可能有问题。

尝试在您的应用程序目录中创建一个 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 Files\Adobe\Adobe Media Server 5\applications\HelloWorld\</Streams> 
        </VirtualDirectory> 
    </StreamManager> 
</Application>
