GetID3 documentation and installation help

Greetings,

By default getid3 path is built from module path and one more '/getid3' folder.

function getid3_get_path() {
  return variable_get('getid3_path', drupal_get_path('module', 'getid3') .'/getid3');
}

When visiting settings page after enabling module it says getid3 lib is not found and the path is 'modules/getid3/getid3' which is correct.

Here is the reason - you are adding one more superfluous folder '/getid3/getid3.php':

function _getid3_admin_settings_check_path($form_element) {
  $path = $form_element['#value'];
  if (!is_dir($path) || !file_exists($path .'/getid3/getid3.php')) {
  ......

You probably have to change it to:

  ......
  if (!is_dir($path) || !file_exists($path .'/getid3.php')) {
  ......
