Любая идея, как я могу исправить видео с неточными метками времени от повреждения моего поколения миниатюр?
Как я получаю продолжительность с PHP
preg_match('/Duration: (.*?),/', implode("\n",$output), $matches);
$duration_string = $matches[1];
list($hr,$m,$s) = explode(':', $duration_string);
$duration = ( (int)$hr*3600 ) + ( (int)$m*60 ) + (int)$s;
$duration = (int) $duration;
