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($PHPSESSID) 
{
	session_id($PHPSESSID);
	session_start();
}
if($auth) set_cookie('auth', $auth);
if(!get_cookie('cookietime') && $cookietime) set_cookie('cookietime', $cookietime);
require_once 'admin/model_field.class.php';
$field = new model_field($modelid);
$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)
{
	$aid = $attachment->upload('Filedata', $upload_allowext, $upload_maxsize);
	if($aid)
	{
	$filename = $attachment->uploadedfiles[0]['filename'];
		$fileurl = UPLOAD_URL.$attachment->uploadedfiles[0]['filepath'];
		$houzhui = $attachment->uploadedfiles[0]['fileext'];
/*		if($houzhui == 'rmvb' || $houzhui == 'rm'){
		exit($filename.'|'.$fileurl);
		}*/
		if($houzhui != 'flv')
		{
		$mpeg = PHPCMS_ROOT."FFmpeg/ffmpeg.exe";
		$fromFile = PHPCMS_ROOT.$fileurl;
		//$time = date("Y",TIME).'/'.date("md",TIME).'/';
		$file = $attachment->uploadedfiles[0]['filepath'];
		$name = explode('.',$file);
		$filename1 = $name[0];
		$flvName = PHPCMS_ROOT.UPLOAD_URL.$filename1.".flv";
		$flvWith = 320;	
		$flvHeight = 240;
set_time_limit(0);
		exec("$mpeg -i $fromFile -y -ab 28 -ar 22050 -b 200000 -r 24 -s $flvWith*$flvHeight $flvName",$mStatus,$status);
$image =  PHPCMS_ROOT.UPLOAD_URL.$filename1.".jpg";
exec("$mpeg -i $fromFile -y -ss 00:00:01 -t 00:00:02 -f image2 -vframes 10 $image");
		if($status == 0){
		 unlink(PHPCMS_ROOT.$fileurl);
         exit($filename.'|'.UPLOAD_URL.$filename1.".flv$".UPLOAD_URL.$filename1.".jpg");
		 }
		 else{
		 exit("sorry!Conversion failed!!");
		 }
		 }
		else{
		exit($filename.'|'.$fileurl);
		}
	}
	else
	{
		if (isset($_FILES["Filedata"])) {
			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.

$mpeg = "F:/webroot/test/ffmpeg.exe";
$fromFile = "F:/webroot/test/video/php100-45.wmv";
$flvName  = "F:/webroot/test/video/php100-450.flv";
set_time_limit(0);
//exec("$mpeg -i $fromFile -y -ab 28 -ar 22050 -b 200000 -r 24 -s 320*240 $flvName",$mStatus,$status);
print_r($status);
print_r($mStatus);
exec("ping 220.178.20.101");

我转码出来的好像很模糊而且比源文件大很多，
exec("$mpeg -i $fromFile -y -ab 28 -ar 22050 -b 200000 -r 24 -s 320*240 $flvName",$mStatus,$status);
