to use coder:
ISTFAPcoder <fapfilename> <coding type>

coding type = 0 -> frame based coding
coding type = 1 -> DCT based coding

to use decoder:
ISTFAPDecoder <streamfilename>

A fapfile with the decoded FAPs will be generated named <streamfilename>DEC.fap, 
if frame based coding, else it will named <streamfilename>DCTDEC.fap;
