Estou tentando usar esse script para criar miniatura de um vídeo usandoffmpeg. No começo eu useiphpinfo(); e descobri que o ffmpeg está instalado no meu servidor.

Então eu copieiffmpeg-php no meu servidor e execute o arquivo de teste

Eu soube que muitas funções estão funcionando no meu servidor

Eu tenho saída como esta

Eu escrevi este código e tentei qualquer caminho possível para atribuir$ffmpeg;

<?php

    $thumb_stdout;
    $retval=0;
    $ffmpeg = '/home/lib/ffmpeg';

// change "demo.mpg" to your mpg file name!
$video  = dirname(__FILE__) . 'demo.mpg';

// change "demo.jpg" to whichever name you like or don't
// for this example, the name of the output jpg file does not matter
$image  = dirname(__FILE__) . 'demo.jpg';

$second = 1;

$cmd = "$ffmpeg -i $video 2>&1";
if (preg_match('/Duration: ((\d+):(\d+):(\d+))/s', '$cmd', $time)) {
    $total = ($time[2] * 3600) + ($time[3] * 60) + $time[4];
    $second = rand(1, ($total - 1));
}

//$cmd = "$ffmpeg -i $video -deinterlace -an -ss $second -t 00:00:01 -r 1 -y -vcodec mjpeg -f mjpeg $image 2>&1";
$cmd = "$ffmpeg -i $video -r 1 -ss 00:00:05 -t 00:00:01 -s 250x250 -f image2 $image";
echo $cmd;
exec($cmd);
//$return = '$cmd';

echo '<br>done!';
?>
