Como instalar ffmpeg en windows?

[magTpeak]

me pasa igual :(
me dice: Can't load extension C:\php5/ffmpeg.dll

$extension = "ffmpeg";
$extension_soname = $extension . "." . PHP_SHLIB_SUFFIX;
$extension_fullname = PHP_EXTENSION_DIR . "/" . $extension_soname;

// load extension
if (!extension_loaded($extension)) {
echo "Can't load extension $extension_fullname\n";
}
