ffmpeg is the key. Here is how to use it to produce flv:

You can call ffmpeg from php by using system function.

Sorry. I missed the part about Windows. There are tutorials on how to build ffmpeg under Windows:
http://arrozcru.no-ip.org/ffmpeg_wiki/tiki-index.php. But it sounds rather complicated.

I'm much more acquainted with Linux that Windows, so I probably can't help you to find Windows specific software.

audio for ffmpeg

hello,
i am working on an unix server where i am able to convert my video file into an flv format but the audio is nt available in the converted file can u tell me what would be the problem

php file
--------
<?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 $ffmpegcmd1;
}
function grab_image($filename, $rootpath, $inputpath,$outputpath, $no_of_thumbs, $frame_number, $image_format, $width, $height)
{
// root directory path
$_rootpath = $rootpath."\ffmpeg";
// Media Size
$size = $width."x".$height;

// I am using static image, you can dynamic it with your own choice.
$out=explode(".",$filename);

$outfile = $out[0].".jpg";

$ffmpegcmd1 = "/usr/local/bin/ffmpeg -i ".$inputpath."/".$filename." -vframes ".$no_of_thumbs." -ss 00:00:03 -an -vcodec ". $image_format." -f rawvideo -s ".$size. " ". $outputpath."/".$outfile;

$ret = shell_exec($ffmpegcmd1);

// Execute this command using exec command or any other tool to grab image from converted flv file.
return $ffmpegcmd1;
}
}
?>

can u help me out.......
thanku

sridivya, if you would only look into the help for ffmpeg

it says:

Audio options:
-aframes number set the number of audio frames to record
-ab bitrate set audio bitrate (in kbit/s)
-ar rate set audio sampling rate (in Hz)
-ac channels set number of audio channels
-an disable audio
-acodec codec force audio codec ('copy' to copy stream)
-vol volume change audio volume (256=normal)


so, remove -an from your params list, and it will work

Theres also the FFmpeg extension for PHP.

$ffmpegObj = new ffmpeg_movie($srcFile);


$srcWidth = makeMultipleTwo($ffmpegObj->getFrameWidth());
$srcHeight = makeMultipleTwo($ffmpegObj->getFrameHeight());
$srcFPS = $ffmpegObj->getFrameRate();
$srcAB = intval($ffmpegObj->getAudioBitRate()/1000);
$srcAR = $ffmpegObj->getAudioSampleRate();


$command = $ffmpegPath . " -i " . $srcFile . " -ar " . $srcAR . " -ab " . $srcAB . " -f flv -s " . $srcWidth . "x" . $srcHeight . " " . $destFile . " | " . $flvtool2Path . " -U stdin " . $destFile;
