Answer 2

檢查了這一點..這個代碼應工作

<?php 
class media_handler 
{ 
function convert_media($filename, $rootpath, $inputpath, $outputpath, $width, $height, $bitrate, $samplingrate) 
{ 
$outfile = ""; 
// root directory path, where FFMPEG folder exist in your application. 
$rPath = $rootpath."\ffmpeg"; 
// which shows FFMPEG folder exist on the root. 
// Set Media Size that is width and hieght 
$size = $width."x".$height; 
// remove origination extension from file adn add .flv extension, becuase we must give output file name to ffmpeg command. 
$outfile =$filename; 
$out=explode(".",$outfile); 


// Media Size 
//$size = Width & "x" & Height; 

// remove origination extenstion from file and add .flv extension , becuase we must give output filename to ffmpeg command. 

$outfile = $out[0].".flv"; 
// Use exec command to access command prompt to execute the following FFMPEG Command and convert video to flv format. 

$ffmpegcmd1 = "/usr/local/bin/ffmpeg -i ".$inputpath."/".$filename. " -ar " .$samplingrate." -ab ".$bitrate." -f flv -s ".$size." ".$outputpath."/".$outfile; 

//$ffmpegcmd1 = "/usr/local/bin/ffmpeg -i ".$inputpath."/".$filename. " -b 500 -r 25 -s 320×240 -hq -deinterlace -ab 56 -ar 22050 -ac 1 ".$outputpath."/".$outfile." 2>&1"; 


$ret = shell_exec($ffmpegcmd1); 

// return output file name for other operations 
return $ffmpegcmd1; 
} 

} 
?> 

Answer 3

include_once（ 「media_handler.php」）;

$ _objMda = new mandler（）; // $ _ objMda as new mandler（）;

$ rootpath =「」; $ nputpath = $ rootpath。「/ Default」; $ outputpath = $ rootpath。 「/ FLV」; $ ThumbPath = $ rootpath。 「/大拇指」;

if（$ _POST）{//將原始視頻保存在默認文件夾中。

$ source = $ _FILES ['file1'] ['tmp_name']; $ name = $ _FILES ['file1'] ['name']; $ fileSize = $ _FILES ['file1'] ['size']; $ filetype = $ _FILES ['file1'] ['type']; $ dest ='';

copy（$ source，$ inputpath。$ name）;

//轉換成FLV格式

$ OUTFILE = $ _objMda-> convert_media（$名稱，$ ROOTPATH，$ inputpath，$ outputpath，320，240，32，22050）;

我用過烏爾班，但沒有結果先生。我可以在我的phpini上設置任何事情嗎？
