Re:morse.nl

And again i searched the internet for some “easy” script to grab/download youtube movies to my own server.
I failed! So wrote my own.

Let me explain the steps or jump over to the VERY short working code:

First step we need to do 3 things:

*1: make a request to youtube for getting the required data
*2: make a second request to really get the .FLV file
*3: save the data to a file

*1: make a request to the url, in this case it is:

(just grabbed a url dont look at the content of it )

*2: Grab the source and strip it because we need a hash and a video id
(the video id could also be catched from the above url)
video_id = 22bS3WLWPpE (speak for itself)
t hash = OEgsToPDskK7nRQvAd4WaR2IXy0TY1mr ( different wich each request)
Basicly i didnt found out about t hash… some others did it.
Some guys say that this hash selects the right server to get the movie from.
Some others say that it is just for security reasons…

*3: just save the data to a file

Well this is what i came up with (COULDNT BE EASIER!).

<?php
//REMORSE.NL! goz the world should be free!

//this script creates a file called test.flv,
//base on a youtube url,
//in the directory where this script is

/*
 * set parameters
 */
$url = "http://www.youtube.com/watch?v=22bS3WLWPpE";
//video_id now hardcoded... but should here be grabbed from above url
$video_id = '22bS3WLWPpE';
//this will be the name of the file that will be created
$video_filename = 'test.flv';

/*
 * first call
 */
$curl = new Curl($url);
$page = $curl->curl_get();

/*
 * get the stuff we need from the source
 */
//look for video id... could also be grabbed from above video id..
preg_match('/"video_id": "(.*?)"/', $page, $match);
$var_id = $match[1];
//look for the t hash in the source...
preg_match('/"t": "(.*?)"/', $page, $match);
$var_t = $match[1];

//build the new url
$url = "";
$url .= $var_id;
$url .= "&t=";
$url .= $var_t;
$url = "http://www.youtube.com/get_video?video_id=".$url;
/*
 * make the new request...
 */
$curl = new Curl($url);
$fileContent = $curl->curl_get();
//write to the file
$curl->writeToFile($fileContent,$video_filename);

class Curl{

	  // Vars, basic:
  var $curlInstance = NULL;
  var $url     		= NULL;

  // Constructor:
  function Curl($url)
  {
  	//set the url
    $this->url = $url;
	//initialize
    $this->curlInstance  = curl_init();
    //set some options
    curl_setopt($this->curlInstance, CURLOPT_URL,            $this->url);
    curl_setopt($this->curlInstance, CURLOPT_TIMEOUT,        25);
    curl_setopt($this->curlInstance, CURLOPT_FOLLOWLOCATION, TRUE);
    curl_setopt($this->curlInstance, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($this->curlInstance, CURLOPT_HTTPHEADER,     array("Content-type: app/xml"));
    curl_setopt($this->curlInstance, CURLOPT_FOLLOWLOCATION, TRUE);
  }

  function curl_get()
  {
  	//execute the curl
    $returningData = curl_exec($this->curlInstance);
	//close the curl
    curl_close($this->curlInstance);
	//need to say more?
    unset($this->curlInstance);
    return $returningData;
  }

  //just write the file
  function writeToFile($data,$video_filename){
  	$video_filename = dirname(__FILE__).DIRECTORY_SEPARATOR.$video_filename;
  	if ($o = fopen ($video_filename, "w")) {
		fwrite($o,$data);
		fclose ($o);
		print "Done writing to: ".$video_filename;
	}else{
		print 'ERROR';
	}
  }

}

?>

Soon I will release a nice php class that can do things u havent seen yet….
