Uhuru kaka wangu na dudu wangu!
i found this and thought ones and ones may find it usefull..
Ever wanted to rip a video from YouTube without downloading software? - Well now you can! Their tracking ID's can't stop us!
After analysing their structure and flash code I found a way around it. The end result will be a .FLV file, not a .wmv or .mov, etc.
First, you need the flash video ID. I'm going to use Jamelia's Beware of the Dog video for this example.
Go find the video you want to watch then get it's ID. h*ttp://www.youtube.com/watch?v=A2P4Zesf_l4
The video ID is: A2P4Zesf_l4
Now in your browser head to: h*ttp://www.youtube.com/v/A2P4Zesf_l4
You'll get back this long URL in your browser window: h*ttp://www.youtube.com/p.swf?video_id=A2P4Zesf_l4&eurl=&iurl=http%3A//sjl-static10.sjl.youtube.com/vi/A2P4Zesf_l4/2.jpg&t=OEgsToPDskJG2DA_SllJWE481mMNotYZ
What you need to extract is the &t= variable. This is like a tracking ID which I'm pretty sure changes every hour or day (not really sure).
Anyway, the tracking variable is right at the end of the URL and it's this: OEgsToPDskJG2DA_SllJWE481mMNotYZ
Next point your browser to this URL and replace the ID and T_ID with the file ID and tracking ID: http://h*ttp://www.youtube.com/get_v...o_id=ID&t=T_ID
So thats: http://h*ttp://www.youtube.com/get_v...lJWE481mMNotYZ
Now just change the file name to something you remember and don't forget to add .flv at the end. Now you'll need to convert it to a nice format (.wmv or .mov). I'm not going to tell you how to do that, but you can use Google to search for a flash to video converter.
