Chromium Hack - Save hidden cached video
Channel: RogueTube
Date: 21/10/2011

Created a script that allows videos to be copied from the cache directory in Ubuntu.

Got the info from this site:
http://superuser.com/questions/235535/in-google-chrome-on-linux-where-is-the-flv-if-not-in-tmp

this could also help with copying cached files:

I'm still working on the script but I'll share it when I've implemented everything I want and worked out the bugs. 

PS. will not work with hulu, but the trick works with all other websites that stream flash. ;)
