How to get redirector.googlevideo.com link from a Google drive video

I have a google drive video file (like https://drive.google.com/file/d/FILE_ID/view) and I want to get its redirector.googlevideo.com link.

How do sites like http://api.getlinkdrive.com/ do it? I've tried using the Google Drive REST API, (both v2 and v3) but still can't find a way to do it. Many tv-show and movie sites host their content on google drive, and use this "cloaked" URL that expires so you can't for example embed it somewhere else.

The closest I've gotten is by going to docs.google.com/get_video_info?docid=FILE_ID and getting the fmt_stream_map links, but that doesn't return the redirector link which I need.

please include code – Miheretab Alemu
Thanks @DaImTo, but that's not what I am asking, please re-read the question. – chenophucu
@MiheretabAlemu There is no code needed to be shown, I am asking how to retrieve the redirector.googlevideo.com link from a google drive video. – chenophucu
Found this forum which suggested to create a direct link for the document stored on Google Drive. Here's a tutorial which explains how to create a direct link for a file hosted in Google Drive and a tool which can automatically create the direct links for you. You may also check on this thread which might help. – abielita
@abielita Thank you, but it's not what I'm looking for like I mentioned in my question. The whole purpose is to hide the original drive file ID, and to provide a redirector.googlevideo.com link specifically, like many video-streaming sites such as kissanime.to do. – chenophucu

Php code will not work here and even meaningless, because it will return the result for server side.

This is my Javascript/Ajax code. Unfortunately, you should use Access-Control-Allow-Origin extension in Chrome browser. First, please see this screenshot of console window.

          console.log('Query variable %s not found', variable);
          return "";
      }

   </script>
</html>

This code works basically, but doesn't play in jwplayer component.

However, if you enter this URL, "https://docs.google.com/get_video_info?docid=0B4Mn0g4wWmQ1ZThycVhOcDJQc2c", directly in chrome browser, get JSON file , parse it manually, use one of URLs directly in this code as jwplayer's file url, it works perfectly, although it contains "app=explorer" tag in itself.

I'm not sure why this happens. So I tried to compare 2 links and some parameters is different. The first one is from above code and not working, the 2nd JSON file directly and working.)

Why first one is not working while 2nd is working? Any idea of this?

He is talking about getting the URL from google drive all qualities in 360p,480p,720p,1080p and convert just before the /videoplayback to redirector.googlevideo.com and make it as video/mp4 to do playback in JW Player.I have the full script but it has got a minor problem it says forbidden 403 and it is because of changes google made in API.Have a look at the codes in PHP and let me know if someone can fix it,i will post full script later. 

function Drive($link) {
    $url = urldecode($link);
    $get = curl1($url);
    $data = explode(',["fmt_stream_map","', $get);
    $data = explode('"]', $data[1]);
    $data = str_replace(array('\u003d', '\u0026'), array('=', '&'), $data[0]);
    $data = explode(',', $data);
    asort($data);
    foreach($data as $list) {
        $data2 = explode('|', $list);
        if($data2[0] == 37) {$q1080p = preg_replace("/\/[^\/]+\.google\.com/","/redirector.googlevideo.com",$data2[1]);}    // 1080P
        if($data2[0] == 22) {$q720p = preg_replace("/\/[^\/]+\.google\.com/","/redirector.googlevideo.com",$data2[1]);}     // 720P
        if($data2[0] == 59) {$q480p = preg_replace("/\/[^\/]+\.google\.com/","/redirector.googlevideo.com",$data2[1]);}     // 480P
        if($data2[0] == 18) {$q360p = preg_replace("/\/[^\/]+\.google\.com/","/redirector.googlevideo.com",$data2[1]);}     // 360P
    }
    $js[0][0] = "$q1080p";
    $js[0][1] = "$q720p";
    $js[0][2] = "$q480p";
    $js[0][3] = "$q360p";
    $js[1][0] = "1080P";
    $js[1][1] = "720P";
    $js[1][2] = "480P";
    $js[1][3] = "360P";
    return $js;     
}
if ($jw[0][0] != "") {
    echo('{file: "'.urldecode($jw[0][0]).'",type: "video/mp4",label: "'.urldecode($jw[1][0]).'"},');
}
if ($jw[0][1] != "") {
    echo('{file: "'.urldecode($jw[0][1]).'",type: "video/mp4",label: "'.urldecode($jw[1][1]).'"},');
}   
if ($jw[0][2] != "") {
    echo('{file: "'.urldecode($jw[0][2]).'",type: "video/mp4",label: "'.urldecode($jw[1][2]).'"},');
}   
if ($jw[0][3] != "") {
    echo('{file: "'.urldecode($jw[0][3]).'",type: "video/mp4",label: "'.urldecode($jw[1][3]).'"},');
}

I implemented a better algorithm from the previous answer.

function curl($url){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER, $return);
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
}

function Drive($id) {
    $o = [];
    $url = "https://docs.google.com/get_video_info?docid=$id";
    $get = curl($url);

    parse_str($get, $out);
    $data = explode(",", $out["fmt_stream_map"]);

    foreach($data as $d) {
        switch ((int)substr($d, 0, 2)) {
            case 18:
                $r = "360P";
                break;
            case 22:
                $r = "720P";
                break;
            case 37:
                $r = "1080P";
                break;
            case 59:
                $r = "480P";
                break;
            default:
                break;
        }
        $o[$r] = substr(preg_replace("/\/[^\/]+\.google\.com/","/redirector.googlevideo.com", $d), 3);
    }
    ksort($o);
    return $o;
}
$jw = Drive(FILE_ID_HERE);

foreach ($jw as $k => $r) {
    echo json_encode(array("file"=> $r, "type"=> "video/mp4", "label"=> $k))."\n";
}
