Question

我正在尝试使用此脚本使用 ffmpeg 创建视频缩略图。起初我使用phpinfo();，我发现ffmpeg安装在我的服务器上。

然后我将 ffmpeg-php 复制到我的服务器上并运行测试文件

我知道很多功能正在我的服务器上运行

我得到了像这样的输出

输出： -

我编写了此代码并尝试了任何可能的路径来分配$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!';
?>

最后我得到了代码，感谢 Anubhaw 。您的链接帮了很多。试试这段代码。

            //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);

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

查看代码，使其变得更简单和可运行，也许这对你们中的一些人有帮助。

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;
    }
}

用法是

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