[Coding] Download from youtube (NEW API, June/July 2010)

[s0beit]

Youtube changed their api so all examples using "get_video" are now broken.

here.

PHP Code:

<?php

    $watch_id = $_GET[ 'watch' ];
    
    function parse_swf_config( $content )
    {
        $ret = array();
        
        $e1 = explode( ',', $content );
        
        foreach( $e1 as $e )
        {
            $e2 = explode( '|', $e );
            
            array_push( $ret, array( 'fmt' => $e2[0], 'url' => $e2[1] ) );
        }
        
        
        return $ret;
    }

    function get_youtube_swf_info( $id )
    {
        $ch = curl_init( "http://www.youtube.com/watch?v=" . $id );
        
        curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
        curl_setopt( $ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)" );
        
        $d = curl_exec( $ch );
        
        curl_close( $ch );
        
        if( preg_match( '#var swfConfig = \{(.*)\};#', $d, $f ) )
        {
            return json_decode( '{' . $f[1] . '}', true );
        }
        
        return FALSE;
    }

    echo( "<div align=\"center\">" );

    $new_data = get_youtube_swf_info( $watch_id );
    
    if( $new_data == FALSE )
    {
        die( "Unable to parse youtube swf parameters...<br />" );
    }
    
    $par_conf = parse_swf_config( $new_data['args']['fmt_url_map'] );
    
    foreach( $par_conf as $video )
    {
        echo( "<a href=\"{$video['url']}\">Download \"{$new_data['args']['rv.2.title']}\" at fmt={$video['fmt']}</a><br />" );
    }
    
    echo( "</div>" );

?>

by the way, i found out that the "$new_data['args']['rv.2.title']" is not reliable, since it is related videos and in fact not the actual video which i somehow did not catch in my test but the code to grab the FMT based links works 100%.

In my more complex version which you can see here, i now use this:

PHP Code:

        function GetTitle()
        {
            if( preg_match( '#<meta name=\"title\" content=\"(.*)\">#', $this->cachedpage, $f ) )
            {
                return $f[1];
            }
            
            return "Unable to parse title";
        } 


EDIT: Also for some reason the code works on my localhost but not very well on my box, i think this could be because im getting different session data from my box and im unable to load it with my ip. Working to fix this.

DOUBLE EDIT: It is indeed session based and whats "resolved" on one computer can not be used on another, i will need to tunnel the file or make a client-based application (like desktop app), either way, you will NEED to run this file on localhost until i post a more complex method.
