ffmpeg-php per creare la miniatura del video

Question

Sto cercando di utilizzare questo script per creare la miniatura di un video utilizzando ffmpeg. All'inizio ho usato phpinfo(); e ho trovato che ffmpeg è installato sul mio server.

Poi ho copiato ffmpeg-php sul mio server ed eseguire il file di prova

ho avuto modo di sapere che molte funzioni stanno lavorando sul mio server

ho ottenuto output come questo

Uscita: -

Ho scritto questo codice e trie d qualsiasi percorso possibile assegnare $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!'; 
?>

Finalmente ho ottenuto il codice grazie al Anubhaw .Your collegamento aiutato lot.Try questo codice.

  //thumb path should be added in the below code 
      //test for thumb 
      $dir_img='uploads/'; 
      $mediapath='123.jpg'; 
      $file_thumb=create_movie_thumb($dir_img.$mediapath,$mediapath,$mediaid); 

      $name_file=explode(".",$mediapath); 
      $imgname="thumb_".$name_file[0].".jpg";  

      /* 
       Function to create video thumbnail using ffmpeg 
      */ 
      function create_movie_thumb($src_file,$mediapath,$mediaid) 
      { 
       global $CONFIG, $ERROR; 

       $CONFIG['ffmpeg_path'] = '/usr/local/bin/'; // Change the path according to your server. 
       $dir_img='uploads/'; 
       $CONFIG['fullpath'] = $dir_img."thumbs/"; 

       $src_file = $src_file; 
       $name_file=explode(".",$mediapath); 
       $imgname="thumb_".$name_file[0].".jpg"; 
       $dest_file = $CONFIG['fullpath'].$imgname; 

       if (preg_match("#[A-Z]:|\\\\#Ai", __FILE__)) { 
        // get the basedir, remove '/include' 
        $cur_dir = substr(dirname(__FILE__), 0, -8); 
        $src_file = '"' . $cur_dir . '\\' . strtr($src_file, '/', '\\') . '"'; 
        $ff_dest_file = '"' . $cur_dir . '\\' . strtr($dest_file, '/', '\\') . '"'; 
       } else { 
        $src_file = escapeshellarg($src_file); 
        $ff_dest_file = escapeshellarg($dest_file); 
       } 

       $output = array(); 

       if (eregi("win",$_ENV['OS'])) { 
        // Command to create video thumb 
        $cmd = "\"".str_replace("\\","/", $CONFIG['ffmpeg_path'])."ffmpeg\" -i ".str_replace("\\","/" ,$src_file)." -an -ss 00:00:05 -r 1 -vframes 1 -y ".str_replace("\\","/" ,$ff_dest_file); 
        exec ("\"$cmd\"", $output, $retval); 

       } else { 
        // Command to create video thumb 
        $cmd = "{$CONFIG['ffmpeg_path']}ffmpeg -i $src_file -an -ss 00:00:05 -r 1 -vframes 1 -y $ff_dest_file"; 
        exec ($cmd, $output, $retval); 

       } 


       if ($retval) { 
        $ERROR = "Error executing FFmpeg - Return value: $retval"; 
        if ($CONFIG['debug_mode']) { 
         // Re-execute the command with the backtick operator in order to get all outputs 
         // will not work if safe mode is enabled 
         $output = `$cmd 2>&1`; 
         $ERROR .= "<br /><br /><div align=\"left\">Cmd line : <br /><span style=\"font-size:120%\">" . nl2br(htmlspecialchars($cmd)) . "</span></div>"; 
         $ERROR .= "<br /><br /><div align=\"left\">The ffmpeg program said:<br /><span style=\"font-size:120%\">"; 
         $ERROR .= nl2br(htmlspecialchars($output)); 
         $ERROR .= "</span></div>"; 
        } 
        @unlink($dest_file); 
        return false; 
       } 

       $return = $dest_file; 
       //@chmod($return, octdec($CONFIG['default_file_mode'])); //silence the output in case chmod is disabled 
       return $return; 
      }

guardato oltre il codice, reso più semplice ed eseguibile, forse questo aiuta alcuni di voi.

class VideoTile 
{ 
    public static function createMovieThumb($srcFile, $destFile = "test.jpg") 
    { 
     // Change the path according to your server. 
     $ffmpeg_path = 'D:\\ffmpeg\\bin\\'; 

     $output = array(); 

     $cmd = sprintf('%sffmpeg -i %s -an -ss 00:00:05 -r 1 -vframes 1 -y %s', 
      $ffmpeg_path, $srcFile, $destFile); 

     if (strtoupper(substr(PHP_OS, 0, 3) == 'WIN')) 
      $cmd = str_replace('/', DIRECTORY_SEPARATOR, $cmd); 
     else 
      $cmd = str_replace('\\', DIRECTORY_SEPARATOR, $cmd); 

     exec($cmd, $output, $retval); 

     if ($retval) 
      return false; 

     return $destFile; 
    } 
} 

L'uso è

$file = VideoTile::createMovieThumb("../video3.mp4");
