How to save this rtmp flash video stream?

My sister wanted me to save http://esewingworkshop.com/video-lesson/overview-zipper-types flash video and amp; a couple more for offline viewing and asked me how to save it.

I immediately released firebug in firefox, but surprisingly the video source is not in requests. http://hwcdn.net/m7n9i8d5/fms/videos/5_Standard_Zipper/B_Overview_of_Zipper_Types.flv.smil is the last request that is made. answer:

<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>

So, I am using the rtmp streaming protocol. I tried to find out the source of this thread. I used "wirehark" and analyzed traffic and monitored TCP Stream

and these are the POST HTTP requests made by the shockwave player (plugin-containing .exe) in order

I do not understand. Am I a little confused about how exactly this message comes about? I can not find the source of the video. As I understand it, from the SMIL request (the browser did this), having received the server address, and then shockwaveplayer takes over the connection and answers to these HTTP POST requests - this video is in pieces.

But how and where does he determine which video he wants? Where is RTMP? what url? How to download it?

I do not see how this is related to programming, but here goes:

  • As where?

    In the SMIL file, you see the base and source of the video. So the full URL (possibly protected):

    RTMP: //fms006.lo1.hwcdn.net/m7n9i8d5/_definst_fms/videos/5_Standard_Zipper/B_Overview_of_Zipper_Types doppl = 965d6485db1d06d2 & dopsig = 867922856d781b57521a1dd3f7

  • Where is RTMP?

    Not sure what you are asking. SMIL explicitly refers to the RTMP stream URL.

  • How to download?

    It would be best to try using any number of third-party tools that can capture HTTP / RTMP streams using various mechanisms.

Not that you asked (and not that it really was a programming issue), but many sites will be unhappy with downloading their content without permission.
