/*******************************************************************************
* Simple example to show the Location2Location class in action. The
* Location2Location class transfer media from one location to another
* performing any requested tanscoding (format changes) at the same time.
*
* The class is used twice. Once to transform a short wave audio file of an
* electric guitar (guitar.wav) into MP3 format. The second example converts of
* Quicktime version of the example video from chapter 7, encoded with the Indeo
* 5.o codec and GSM audio into an AVI version with Cinepak codec for the video
* and linear encoding for the audio.
