Little Python script to recursively process file in a folder

[I12learn]

This script let user of avidemux 2.5 to scan in a folder for certain pattern of filename, later put them into process for a defined format.
Eclosed also a file setting which will convert the output into mp4 (AVC-FAAC-MP4).

Input files may scan recursively into sulfolder, according to option.
I'd like some report for windows user, because I tried just small test.
For usage type jefac -h. If the program doesn't start you may need to invoke it by python jefac or assign the extension to work with python.exe

I'll try the ECMA scripting, for the same purpose, but I'm totally new of that.
I think this script would last as long as avidemux3 will be a bit flawless.
