Sorry if I haven't made my question clear. I don't want to download it from the source(i.e. youtube). I want to get the chunk of the flv file by joining the capture packets only. If anyone knows about any tool or process. please explain...

Thanks, Arjun

Hi Arjun,

Then you need to Export HTTP Objects:

Go to:
File | Export | Object | HTTP
Look for Content Type: video/x-flv
Select: video/x-flv
Click Save As and save as .flv file

This doesn't work anymore. The traffic is now encrypted and the flash video is broken into streams

Yes, I know. I have posted this answer last year on Stackoverflow: I have to look into it again.

I am trying to do the same now. Youtube streams in TCP packets and the TCP DATA SEGMENT contains the fragmented video files. Has anyone figured out how to combine and play these? I am actually looking for a method to determine the length of each fragment. Any help?
