Saving generated thumbnails

[rondog]

Hi,

I am creating JPEG thumbnails of FLVs using ffmpeg. The thing is, it runs ffmpeg every time you hit the page to generate them. I dont know what kind of overhead that makes, but I know it would be less intensive on the server if I saved the generated thumbnail the first time and then just checked if file_exists.

 

Here is my createthumb.php file:

<?php
header("Content-type: image/jpeg");
$moviefile = $_GET['source'];
$mov = new ffmpeg_movie($moviefile,false);
$img = $mov->getFrame(50);
$showImg = $img->toGDImage();
$mkNewImg = new ffmpeg_frame($showImg);

$maxWid = 150;
$oldWid = $mkNewImg->getWidth();
$oldHgt = $mkNewImg->getHeight();
$movRatio = $oldWid/$oldHgt;

if($oldWid > $maxWid) {
$newWid = $maxWid;
}

$newHgt = $newWid / $movRatio;

$mkNewImg->resize($newWid,$newHgt);
$newImg = $mkNewImg->toGDImage();
imagejpeg($newImg, $mkThumbFile,40);

imagedestroy($newImg);
?>

 

How could I modify this to save the thumbnail it makes in a directory. I think I can figure out the checking if it already exists. Just need help saving it. Thank you.

I've been doing some more research and apparently, imagejpeg($newImg,$mkThumbFile,40);

 

the second param is the directory where you save the image. Well, the image isnt getting saved anywhere. I have a folder in my root called videos/thumbnails and I want the thumbnails to go in there. I tried:

 

imagejpeg($newImg,'videos/thumbnails/$mkThumbFile',40);

 

and it made a file called $mkThumbFile

 

When I right click and save the image I get hte file name: createthumb.php.jpg

 

is that really the name its making? I need to know how to save the jpeg to a directory the same name as

 

$moviefile = $_GET['source'];

 

but ill just strip the FLV extension and put JPG..please anyone??
