Get video source Url from Vk using Actionscript

I need extract the urls sources files for VK.com videos from the client side and send this URLs to my website.

I need an actionscript that work with any url from VK.com. Example use: the user into on my site and he paste the VK.com video url, then the actionscript should be extract the path to the video file and I should bu manipulate this url side server.

I need url source VK.com from client side, why?, because Vk.com is generating a unique random url per video and per ip and then i would like send this url to my site to i can manipulate.


Example possible URL: http://mysite.com/my_actionscript.swf?url_src_video=http://vk.com/video_ext.php?oid=1578474&id=164122105&hash=62e39774a7538778&hd=1

Example: url source from vk.com:
http://vk.com/video_ext.php?oid=1578474&id=164122105&hash=62e39774a7538778&hd=1

full path to files to get from this source url (this depends on different video quality options there.):
240p [vk] - http://cs523210v4.vk.me/u158901313/video/db897200de.240.mp4
360p [vk] - http://cs523210v4.vk.me/u158901313/video/db897200de.360.mp4
480p [vk] - http://cs523210v4.vk.me/u158901313/video/db897200de.480.mp4
720p [vk] - http://cs523210v4.vk.me/u158901313/video/db897200de.720.mp4

There are many docs about that, and many examples how to get the final full path to files
There is a python example script: https://code.google.com/p/getvk/
