Вземане на директният линк на клипчето от youtube

[webdeveloper]

Как мога да взема директният линк (тоест да завършва на .flv) към дадено клипче от youtube?

<?php 
// first function, read HTML from youtube 
function get_content_of_url($url){ 
    $ohyeah = curl_init(); 
    curl_setopt($ohyeah, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ohyeah, CURLOPT_URL, $url); 
    $data = curl_exec($ohyeah); 
    curl_close($ohyeah); 
    return $data; 
} 

// second function, get path that lead into movie files 
function get_flv_link($string) { 
        if (preg_match('/\/player2\.swf\?(.*)", "movie_player"/', $string, $match)) { 
            $url = $match[1]; 
            return 'http://youtube.com/get_video.php?'.$url; 
        } 
} 

// third function, read header returned by second function above 
function get_http_header($url){ 
    $uh = curl_init(); 
    curl_setopt($uh, CURLOPT_URL, $url); 
    curl_setopt($uh, CURLOPT_HEADER, 1); 
    curl_setopt($uh, CURLOPT_RETURNTRANSFER, 1); 
    $res = curl_exec($uh); 
    curl_close($uh); 
    return $res; 
} 

// fourth function, parse the header and show only the link 
function show_url($http_header){ 
    $arai = explode("\n",$http_header); 
    foreach($arai as $ini){ 
        if(eregi("location",$ini)) $url = $ini; 
    } 
    list($sampah,$hasil) = explode("Location:",$url); 
    return str_replace("\n","",trim($hasil)); 
} 

// fifth function, join the four functions above 
function download_youtube($url){ 
    $data = get_content_of_url($url); 
    $next_url = get_flv_link($data); 
    $data = get_http_header($next_url); 
    return show_url($data); 
} 
?>


Usage Example
<?php 
error_reporting(0); // <-- to eliminate error report 
ini_set("max_execution_time",0); // <-- to avoid operation timed out 
echo download_youtube("http://youtube.com/watch?v=O-Tt229laCE"); 
?>
