Question

How can I convert FLV to WMV? Is there any script around there or some way I can integrate this?

Thank you!!!

I don’t think you can do this directly with PHP.
But, you can use external tools called form PHP (ffmpeg for example).

Here is a code sample:

<?php

$src = "file.flv";
$output = "file.wmv";
ffmpegPath = "/path/to/ffmpeg";
$flvtool2Path = "/path/to/flvtool2";

$ffmpegObj = new ffmpeg_movie($src);

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

exec($ffmpegPath . " -i " . $src . " -ar " . $srcAR . " -ab " . $srcAB . " -vcodec wmv1 -acodec adpcm_ima_wav -s " . $srcWidth . "x" . $srcHeight . " " . $output. " | " . $flvtool2Path . " -U stdin " . $output);

// Make multiples function
function makeMultipleTwo ($value)
{
$sType = gettype($value/2);
if($sType == "integer")
{
return $value;
} else {
return ($value-1);
}
}
?>
