Les cuento que estoy desarrollando un portal de videos, y tengo este codigo para los thumbnails (las miniaturas de cada video), funciona bien, el problema es que saca la foto del primer cuadro del video, que por lo general es negro, lo que hace que todos los thumbnails sean cuadritos negros..... si alguien pudiera ayudarme a hacer que tome la foto del segundo 5, 6 o 7.... viene siendo como el cuadro #180 aproximadamente....
Muchisimas Gracias, aqui dejo el codigo
Código :
//Special Function Used TO get duration

$time .= date("i:s",$duration);
}
return $time;
}
