【问题描述】:
我已在 Windows 7 上启动并运行 Adobe 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闪存文件。
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
为了实现这一点,我编写了一些代码,并将其粘贴在下面。
重要的位在netConnectionHandler 函数下。
我现在发布的NetStream 给了我一个StreamNotFound 错误
我的视频路径是
C:\Program Files\Adobe\Adobe Media Server 5\applications\HelloWorld\sample.mp4
nc.connect 服务器路径是rtmp://localhost/HelloWorld
我正在关注 these official instructions 来执行此操作,但我无法使其正常工作。
当执行如下ns.play 时,我收到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.

【问题讨论】:
-
您是否尝试过使用内置 VOD 应用程序?将您的媒体文件放在那里。
-
这是从服务器流式传输视频的唯一可能方式吗?目标是制作我自己的应用程序
-
这不是唯一的方法,但您可以将其作为起点并根据需要进行修改。您的问题可能是在您的连接中使用了“媒体”路径。您的应用程序代码/设置告诉它在哪里寻找媒体,而不是您的连接。您的连接应该是:
rtmp://localhost/helloworld/sample -
您要么必须更改应用程序 xml 文件中的
storageDir参数,要么将您的媒体文件重命名为streams(默认位置) -
@LDMediaServices
rtmp://localhost/helloworld/sample路径返回相同的StreamNotFound错误。sample,但返回Play.Start事件。但是,我看不到任何视频或音频
