Splitting/Joining MPEG Files with mpgtx

"mpgtx" offers a function to split a large MPEG file into small MPEG files. It also offers a reverse function to join small MPEG files into a large MPEG file. I tried both split and join functions with sample music MP3 file.

Split music_full.mp3 into 5 equal parts:

C:\temp>\local\bin\mpgtx -5 music_full.mp3 -b music_part
Skipped -2 zeroes at start of file
mpgtx: AT EOF - please stop me!
mmm, this file does not start with a pack, offset: -2
use the desperate_mode switch as the first option -X to search for a header in t
he whole file!
if you want to force the operation. May yield to an endless loop if no valid hea
der is found!
Does not even begin with a 00 00 01 xx sequence!
