ffmpeg and php video conversion

[Tony404]

Hello

I have recently been trying to covert uploaded video into flv so that its playable on a flash player. I trying to use ffmpeg which is installed

on my hosting plan server.

I have been able to grab thumbnails using ffmpeg but now need to convert the video into flv. The code I have does a conversion but the

file is 0kb when its outputted to the Videos folder;

This is the code:

$src = "Videos/robot.avi";
$output = "Videos/robot.flv";
$ffmpegPath = "ffmpeg";
$flvtool2Path = "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);
}
}

I dont have flvtools but they are not nessary as they only collect meta data.

Thank you,

I've got a feeling that this topic may be a little out of place here.

Have you had a look at PHPMotion, a free, open source video upload/conversion/sharing script?

http://www.phpmotion.com/

You could download and take it apart to see how it works... it's free and won't cost you anything to at least look at it.

I use it on one of my sites for file conversion and it seems to work just fine.

Best wishes,

Hello

Thanks alot for the reply. I have check out the phpmotion it seems really good but I really need to use ffmpeg. The reason is I have a hosting plan that has ffmpeg installed on the server which works well with my exsisting code. I have already used ffmpeg to grab thumbnail every time some one uploads a file but now I just need to convert uploaded files into flv. The code I uploaded does that but the converted file for some reason is 0 kb when inside folder.

Thanks.

PHPMotion is ffmpeg based and is open source.

My suggestion was to download the source code and see how they use it for file conversion.
