How to create a youtube embedder?

I created a video hosting si开发者_StackOverflowte I would like to create a form on my site where you post the youtube embed code and the video is played in jw player on my site and gets added to playlist, what should I look for to create such form?

EDIT:

@Marc B:

okay sir, is there any tutorials out there or anything just to see how it works? I mean how to create the form? I have no problem using youtube player lol :D

<?
$yt_video = "http://www.youtube.com/watch?v=AfgdUfDgCq8"; //OR   $yt_video = $_GET['id']; // http://www.youtube.com/watch?v=AfgdUfDgCq8

if (preg_match('%(?:youtube\.com/(?:user/.+/|(?:v|e(?:mbed)?)/|.*[?&]v=)|youtu\.be/)([^"&?/ ]{11})%i', $yt_video, $match))
 {

/* regex works with:

$jw = <<< EOF

<script type='text/javascript' src='jwplayer.js'></script>

<div id='mediaspace'>This text will be replaced</div>

<script type='text/javascript'>
  jwplayer('mediaspace').setup({
    'flashplayer': 'http://player.longtailvideo.com/player.swf',
    'file': '{$yt_video}',
    'controlbar': 'bottom',
    'width': '470',
    'height': '320'
  });
</script>
EOF;

echo $jw;

}else{ 
echo "invalid youtube video";    
}
?>

Download jwplayer and change player.swf and jwplayer.js locations. GL :)

I think that youtube has a template for embeded videos.
