I'm just migrating my Piwigo from a local Linux (ubuntu) system with PHP5 to a hosted Linux vServer  running Ubuntu 16.x as well, but with PHP7.0. As soon as I activate Charlie's content plugin and try to open a video file, I get the following error message:

Fatal error: Uncaught Error: Class 'getid3_lib' not found in /raid1/www/vhosts/....../htdocs/plugins/charlies/getid3/getid3/getid3.php:270 Stack trace: #0 /raid1/www/vhosts/...../htdocs/plugins/charlies/charlies.inc.php(45): getID3->analyze('././galleries/E...') #1 /raid1/www/vhosts/...../htdocs/plugins/charlies/main.inc.php(140): Charlies_content(Array) #2 /raid1/www/vhosts/..../htdocs/include/functions_plugins.inc.php(229): render_Charlie_element_content('', Array) #3 /raid1/www/vhosts/...../htdocs/picture.php(989): trigger_change('render_element_...', '', Array) #4 {main} thrown in /raid1/www/vhosts/...../htdocs/plugins/charlies/getid3/getid3/getid3.php on line 270

Do you know what could be wrong here? I'm using Apache as the Webserver.
