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

chenophucu picture chenophucu · Feb 8, 2017 · Viewed 29.4k times · Source

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.

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.

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?
