the segment file names are predictable.
In live streaming enviroment somebody predicting the segment name may 
see the program some seconds earlier than any other viewer by 
downloading continously the unpublished segment. (with one segment 
duration seconds earlier)
if the currently writed segment name is constant you may prohibit to 
acces it in web server config
