If you are using ffmpeg on your dedicated server then you can use below bash script for batch convert of flv files to other required video format.

#!/bin/sh
for f in *.flv;
do
echo “Processing $f”
ffmpeg -i “$f” -target ntsc-dvd “${f%.flv}.mpg”
done

Thus using above script all flash video files having flv extension will get converted into a ntsc dvd format with file extension mpg. You can tweak it for required video format you need.
