我需要从视频中创建屏幕截图。
我已经关注这在 Windows 8、php 5.3 中进行初始设置的教程。
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 ";
}
输出:
Thumbnail created
Thumbnail for remote url was created
现在,上述代码在我的 Windows 机器上按预期本地运行。我需要在装有 php 5.5 的服务器环境(Linux 服务器)中执行此操作。
如何在装有 php 5.5 的 CentOS 版本 6.5 服务器上配置 ffmpeg。
我已按照以下教程在服务器上安装它:
控制台输出:

但是,当我在服务器上打开我的 php 文件时,出现以下错误:
加载 ffmpeg 时出错
我已经检查过phpinfo()
,显示 ffmpeg 安装在本地但未安装在服务器上。
我还需要做什么才能在 Cent Os 6.5 和 php 5.5 中启用 ffmpeg 扩展?
