Create Thumbnail Images from Flash Video FLVs Folder with Bash Script

I’ve had the problem that I wanted to show a list of Flash videos in a Flex application and I want to show a sample picture of each video. As I have got only the videos stored in a folder and have no jpegs of them, I want to generate those sample jpegs, one for each video in the folder. Thus, I found quite a lot of blog entries that show you how you can create an image from a Flash video with the Open Source tool ffmpeg.

As I want to do this not for a single file but for a whole folder, I have written a bash script, that renders out a frame of each FLV video into a jpeg and saves them into a folder called thumbnails of the folder in which it is lying.
