How to get redirector.googlevideo.com link from a

问题:

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.

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";
}

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.

          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?

I'm pretty sure this was asked a long time ago, but I think I can get you on your path to what you want. So what you're going to want to do is go to Google Photos Settings and check the option that allows your videos in drive to be shown in photos. Return to google photos and select the video you want a direct link to. Right-click on the thumbnail an copy the link. It should something like https://lh3.googleusercontent.com/[long string]=w1278-h719-k-no. The last part , =w1278-h719-k-no, give it a small change to a =m22. It will auto generate a link for you. Hope it goes well for you.

Edit: Sorry, not exactly a googlevideo redirector link, but it works!

Edit: After a bit more of experimentation, I figured out that setting it to =m15 gives you a longer link. It works equally as the first one. Changing the number after the m will give you different resolutions. So, you can experiment with that.

EditL Alright. After even more experimentation, I uploaded two different videos, one to drive and the other to photos. I got the lh3.googleusercontent.com link for both of them and got their direct video links. The one from drive was hosted on r3---something.googleusercontent.com and the one from photos was hosted on r5--something.googlevideo.com. And I thought, what if I replace the r5--something part of it with redirector? I went and did it, and well, what do you know! It worked! And that is how you get yourself a redirector.googlevideo.com link. BUT, I'm still unsure how api.getlinkdrive.com is able to get a redirector.googlevideo.com link. Since the links generated by google are IP specific, meaning it would work for api.getlinkdrive.com, since it requested it with its own IP, but not for another user, with a different IP.

Edit: Forgot to mention this, but I'm sure some people have noticed that some redirect links aren't lh3.googleusercontent.com, but 3.bp.blogspot.com. Well, the following domains can take the place of lh3.googleusercontent.com;

• lh3.googleusercontent.com
• lh4.googleusercontent.com
• lh5.googleusercontent.com
• lh6.googleusercontent.com
• 1.bp.blogspot.com
• 2.bp.blogspot.com
• 3.bp.blogspot.com
