Question

For what i’m trying to do, i use PHP5 in CLI, and cURL extension.
I’m trying to download a file from youtube’s server, it works fine with any navigator,
the link is something like that;

`http://youtube.com/get_video_info?video_id=VIDEO_ID

exemple: http://youtube.com/get_video_info?video_id=9pQxmD6Bhd

When i access this file trough my navigator, it prompt me with a download box for the file
‘get_video_info’, when downloaded the file content some data, ..

The problem is to get this file with cURL, i keep getting this error message;

status=fail&errorcode=2&reason=Invalid+parameters.

This is the code ( i tried to change some option, but i’m not familliar with cURL, so i’m stuck.

$c = curl_init();
curl_setopt($c, CURLOPT_URL, "http://youtube.com/get_video_info?video_id=9pQxmD6Bhd");
curl_setopt($c, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1");
curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
curl_setopt($c, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($c, CURLOPT_HEADER, false);
$output = curl_exec($c);
if($output === false)
{
    trigger_error('Erreur curl : '.curl_error($c),E_USER_WARNING);
}
else
{
    var_dump($output);
}
curl_close($c);

I tried to use some curl_setopt options, like CURLOPT_TRANSFERTEXT with no success.
I definitely need help !

Thanks for answers, and sorry if i did something that dont respect the rules here, it’s my first post.

EDIT
Here is the code to download youtube video ( .ogg ) with php in cli.

<?php 

/*Youtube URL and ID*/
$youtube_video = "http://www.youtube.com/watch?v=Ftud51NhY2I";
$yt_id = explode("=", $youtube_video);
$id = $yt_id[1];

/*
    Functions
*/
function get_link($raw){
    $url = rawurldecode(rawurldecode($raw));
    $url = explode("&qual", $url);      
    return $url[0];
}



/*
    Here we go

    Query video token
*/
$c = curl_init();
curl_setopt($c, CURLOPT_URL, $youtube_video);
curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
curl_setopt($c, CURLOPT_HEADER, false);
$output = curl_exec($c);
if($output === false)
{
    trigger_error('Erreur curl : '.curl_error($c),E_USER_WARNING);
}
else{}
curl_close($c);

/*
    Get Video infos
*/
$c = curl_init();
curl_setopt($c, CURLOPT_URL, "http://youtube.com/get_video_info?video_id=".$id);
curl_setopt($c, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1");
curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
curl_setopt($c, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($c, CURLOPT_HEADER, false);
$output = curl_exec($c);
if($output === false){trigger_error('Erreur curl : '.curl_error($c),E_USER_WARNING);}
else{}
curl_close($c);
/*Get RAW link*/
$temp = explode("url_encoded_fmt_stream_map=url%3D", $output);
$url = explode("=", $temp[1]);
$url = get_link($url[0]);
/*Get Video name*/
$temp = "";
$temp = explode("title=", $output);
$title = explode("&", $temp[1]);
$title = rawurldecode(rawurldecode($title[0]));
$replace = array(':', '+', '\\', '/', '"', '<', '>', '|', '(', ')', '\'');
$title = str_replace($replace, ' ',$title);
//echo $title;
/*
    Download Video
*/
$url  = $url;
$path = $title.'.ogg';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
curl_close($ch);
file_put_contents($path, $data);

echo "Done... \r\n";

?>

Answer 1

You get error message because the video_id parameter isn’t valid.

Try changing that ID and it should work correctly.
