1. Make sure that you can call mediainfo anywhere, some shared hosting provider prevent this from happening, in that case define the full path where mediainfo binary is located, ej. /usr/bin/mediainfo, review your $PATH enviroment var. on PHP.
2. make sure to pass the full path to the file to mediainfo and escape spaces and problematic characters.
3. If you don't have to, don't close your PHP file with the last tag, ej:

file.php:

<?php
echo passthru('mediainfo file.mp3');
// last line, no closing tag needed.
