Question

我姐姐要我救人 http://esewingworkshop.com/video-lesson/overview-zipper-types flash视频＆amp; 更多用于离线观看目的，并问我如何保存它。

我立即在firefox中发射了firebug，但令人惊讶的是视频源不是在请求中。 http://hwcdn.net/m7n9i8d5/fms/videos/5_Standard_Zipper/B_Overview_of_Zipper_Types.flv.smil 是最后一个请求。回应是：

<smil>
<head>
<meta base="rtmp://fms006.lo1.hwcdn.net/m7n9i8d5/_definst_">
</head>
<body>
<video
src="fms/videos/5_Standard_Zipper/B_Overview_of_Zipper_Types?doppl=965d6485db1d06d2&dopsig=867922856d781b57521a1dd3f7c28c5b"></video>
</body>
</smil>

所以，我使用rtmp流媒体协议。我试图弄清楚它的来源这个流。我使用“wireshark”并分析流量并遵循TCP 流

这些是由shockwave flash player制作的HTTP POST请求（plugin-containter.exe）按顺序

我不明白。我对这种沟通的确切方式感到困惑发生了什么？我无法找到视频源。据我所知，来自 SMIL请求（浏览器使它）获取服务器地址然后 shockwaveplayer正在接管这些HTTP的通信和响应 POST请求是块中的视频。

但是＆amp;它在哪里确定它想要的视频？ RTMP在哪里？什么是网址？我该如何下载？

Answer 1

我不知道这是一个与编程相关的问题，但这里有：

如何/在哪里？

在SMIL文件中，您可以看到base和视频源。所以完整的URL（可能受到保护）：

RTMP：//fms006.lo1.hwcdn.net/m7n9i8d5/_definst_fms/videos/5_Standard_Zipper/B_Overview_of_Zipper_Types doppl = 965d6485db1d06d2＆安培; dopsig = 867922856d781b57521a1dd3f7c28c5b
RTMP在哪里？

不确定你在问什么。该 SMIL明确引用RTMP 流URL。
如何下载？

最好的办法可能是尝试使用能够通过各种机制捕获HTTP / RTMP流的任意数量的3rd party tools。

不是你要问的（并不是说这确实是一个与节目相关的问题），但许多网站在未经许可下载内容时会皱眉头。
