如何为 CentOS 6.5 版服务器设置 ffmpeg

Question

我需要从视频中创建一个屏幕截图，

我已按照this 教程在窗口 8，php 5.3 中进行初始设置

1) 我从这里下载了 ffmpeg -[ http://ffmpeg.zeranoe.com/builds/ ] 用于 64 位操作系统。

2）我按照https://www.youtube.com/watch?v=gU49GiWGGAI的视频，所有配置都成功了，phpinfo()显示ffmpeg已经安装好了。

3) 然后我尝试this 看看它是否有效，

成功了

4) 接下来我跟着这个视频教程here 并成功创建了缩略图。

下面是我的代码

/**
 * FFMPEG-PHP Test Script
 *
 * Special thanks to http://www.sajithmr.me/ffmpeg-sample-code for this code example!
 * See the tutorial at http://myownhomeserver.com on how to install ffmpeg-php.
 */
error_reporting(1);
error_reporting(E_ALL ^ E_NOTICE);
// Check if the ffmpeg-php extension is loaded first
extension_loaded('ffmpeg') or die('Error in loading ffmpeg');

// Determine the full path for our video
$vid = realpath('./videos/myvideo.mp4');
$videosize = filesize($vid);
$remoteVideo = 'http://video-js.zencoder.com/oceans-clip.mp4';

//ffmpeg

$ffmpeg = dirname(__FILE__) . "\\ffmpeg\\bin\\ffmpeg";
$imageFile = "1.png";
$image2 = "2.png";
$size = "120x90";
$getfromsecond = 7;
$cmd = "$ffmpeg -i $vid -an -ss $getfromsecond -s $size $imageFile";
$cmd2 = "$ffmpeg -i $remoteVideo -an -ss $getfromsecond -s $size $image2";
if(!shell_exec($cmd)){
    echo "Thumbnail created";
}else{
    echo "Error Creating thumbnail";
}

if(!shell_exec($cmd2)){
    echo "Thumbnail for remote url was created";
}else{
    echo "Error Creating thumbnail for remote url ";
}

---

  OUTPUT
    Thumbnail created
    Thumbnail for remote url was created

现在上面的代码在我的本地窗口机器中按预期工作，我需要在我的服务器环境（Linux 服务器）中使用 php 5.5 进行。如何在 CentOS 6.5 版服务器中使用 php 5.5 配置 ffmpeg。

我已按照本教程将其安装在服务器中

1.http://supportlobby.com/blog/ffmpeg-installation-on-centos-6-5/

2.http://tecadmin.net/install-ffmpeg-on-linux/

但在服务器中，当我打开我的 php 文件时，我收到此错误 Error in loading ffmpeg

我还检查了 phpinfo()，它显示 ffmpeg 安装在我的本地但未安装在服务器中。

在 Cent Os 6.5 php 5.5 中配置 ffmpeg 还需要做什么。

Answer 1

找不到你的安装步骤或命令，需要用ffmpeg-php配置，

#  git clone https://github.com/tony2001/ffmpeg-php.git
#  cd ffmpeg-php
#  make clean
#  phpize 
#  ./configure 
#  make
#  make install

# vim /usr/lib/php.ini 
[ffmpeg]
extension=ffmpeg.so

# pkill -9 httpd
#  /etc/init.d/httpd start

# php -i|grep ffmpeg

ffmpeg
ffmpeg-php version => 0.7.0
