Little helper to list mp4 files and using converter for mp3 transformation

Uses ffmpeg for converting ( https://ffmpeg.org/ )

#Originally for win10

install ffmpeg to running dir (with mp4 files)

#Tested with Linux Mint 19

Building:

-yasm installation required , othwerwise distro config/build scripts (./configure and make) worked ok

Installing:

sudo apt install ffmpeg (much older version what you get with building yourself)

Usage:

Excecute in mp4 directory. ffmpeg tool must be available (for example in same dir / installed to system)
