ffmpeg-php创建视频的缩略图 [英] ffmpeg-php to create thumbnail of video

问题描述

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

I am trying to use this script to create thumbnail of a video using ffmpeg. At first I used phpinfo(); and I found ffmpeg is installed on my server.

然后我复制了 ffmpeg-php 到我的服务器并运行测试文件

Then I copied ffmpeg-php onto my server and run the test file

我知道许多功能都在我的服务器上工作

I got to know that many function are working on my server

我得到这样的输出

输出： -

我写了这段代码，并尝试了任何可能的路径来分配 $ ffmpeg;

I wrote this code and tried any possible path to assign $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!';
?>

最后我得到代码感谢 。您的链接帮助很多。尝试此代码。

At last I got the code thanks to Anubhaw.Your link helped lot.Try this code.

            //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);

                if (preg_match("#[A-Z]:|\\\\#Ai", __FILE__)) {
