MP4Box mix the stdout and stderr up when you run the command in a linux terminal.
You can test it by running MP4Box and separating the standard output and the error output into different files, i.e.:
MP4Box -diso -std sintel_trailer-480p.mp4 > std.out 2> std.err
The information for that mp4 file should be in the std.out file but in fact the std.out is empty but the file std.err contains the information for the mp4 file, this is the result of the MP4Box command.
It should be in the other way around since no error happens.
