## - The IFS takes care of spaces in file and dirnames 
## - your folders may vary
## - what you mount to the folders does not matter
## - in RELDIR, the f5 most likely MUST be edited,
##    since its responsible, how many leading directories 
##    will be removed from the directory structure in order 
##    to append that exact path to the outfile
## - the commented echos are still in place in order to give 
##    you the variables for testing, before running. 
##    just comment the ffmpeg / avconv command with a #
## - on my raspberry I could only use avconv, not ffmpeg. 
##    choose, whatever suits you best
