How to save this rtmp flash video stream?
My sister wanted me to save http://esewingworkshop.com/video-lesson/overview-zipper-types flash video & couple more for offline viewing purposes and asked me how to save it.
I immediately fired firebug in firefox but surprisingly the video source is not in the requests. http://hwcdn.net/m7n9i8d5/fms/videos/5_Standard_Zipper/B_Overview_of_Zipper_Types.flv.smil is the last request that is being made. response being:
<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 its using rtmp streaming protocol. I tried to figure out the source of
this stream. I used "wireshark" and analysed the traffic and followed the TCP
stream

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

I don't get it. I'm little confused about how exactly this communication is taking place? I'm unable to find the video source. As far as I understood, from the SMIL request (browser made it) its getting the server address and then shockwaveplayer is taking over the communication and responses to these HTTP POST requests are the video in chunks.
But how & where is it identifying which video it wants? Where is RTMP? what is the url? How can I download it?
Answer
I don't see how this a programming related question, but here goes:
How/Where?
In the SMIL file, you see base and the video source. So full URL (probably protected):
rtmp://fms006.lo1.hwcdn.net/m7n9i8d5/_definst_fms/videos/5_Standard_Zipper/B_Overview_of_Zipper_Types?doppl=965d6485db1d06d2&dopsig=867922856d781b57521a1dd3f7c28c5b
Where is RTMP?
Not sure what you are asking. The SMIL explicitly references the RTMP stream URL.
How to Download?
Best way would probably be to try using any number of 3rd party tools that are able to capture HTTP/RTMP streams via various mechanisms.
Not that you were asking (and not that this really was a programming related question), but many sites will frown upon downloading their content without permission.
