Lost thumbnail images during server transfer

Does anyone know how to run a batch command to make thumbnail images for .flv files using ffmpeg-php

I recently I had to move to another server. The transfer went well but the thumb nail images where lost to all the video`s and i do not know how to get them back.

The script is Vshare ( http://stonerocket.net/vidz ) theres about 400 video`s that I need to create the thumbnails for.
I really to not want to start over again because I get a reasonable amount of traffic to it.


Any help would be kindly appreciated.

if you have the source of flv, you can create thumbnails.
please contact admin
ok

90% of the files where hotlinked from youtube etc etc.

But I just noticed something else, the .flv files stored on the server have thumb nails but they are the wrong thumb nails. they are to different .flv files.

Please contact admin because some changes made by admin in .php files
OK
