ffmpeg转换视频格式 phpcms在线exec函数版

程序为phpcms,你可以修改下做到你的项目中.此为在线转换,非上一版本的bat批处理版.

<?php
require dirname(__FILE__).'/include/common.inc.php';
if($PHPSESSID)

$info = $field->get($fieldid);
if(!$info) showmessage('指定的字段不存在！');
$upload_allowext = $info['upload_allowext'];
$upload_maxsize = $info['upload_maxsize']*1024;

require_once 'attachment.class.php';
$attachment = new attachment();

if($dosubmit)

		else{
		exit($filename.'|'.$fileurl);
		}
	}
	else
	{

			echo $_FILES["Filedata"]["error"];
			exit;

	}	
}
else 
{
	include template('phpcms','flash_upload');
}
?>

主要看思路哈.说实话,php的exec相当难用,涉及到系统权限等一大堆乱七八糟的东西.有时候真是让人崩溃,最近严重崩溃中,把以前一个项目的代码拷贝来,防止电脑挂了或者电脑没在身边的时候看看.也给大家参考下,有不对的地方还望斧正.
