ffmpeg-php创建视频缩略图

Question

我想用这个脚本来创建视频的缩略图，使用ffmpeg。起初我使用phpinfo();，我发现ffmpeg安装在我的服务器上。

然后我复制的ffmpeg的PHP到我的服务器和运行测试文件

我才知道，很多功能都在我的服务器

我得到的输出喜欢这个

上工作输出： -

我写了这段代码和trie d任何可能的路径分配$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!'; 
?>

最后我得到的代码感谢Anubhaw。您的联系帮lot.Try此代码。

  //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);

       $dir_img='uploads/'; 
       $CONFIG['fullpath'] = $dir_img."thumbs/";

看了看代码，使它更加简单和可运行的，也许这可以帮助你们中的一些。

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; 
    } 
} 

用法

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