Facebook video source url not showing in FB graph api call

I am trying to get direct url of public videos in FB.

Following recommendation in this question,

How can I download a video from Facebook using GraphAPI?

I tried to invoke for the following fields. source, status, title using below url

https://graph.facebook.com/10158167232321509?access_token=xxxxxx&fields=source,status,title

only return status, title and id. No video source url.

Based on the documentation,
https://developers.facebook.com/docs/graph-api/reference/video/

source should be a string type containing A URL to the raw, playable video file.

Any idea why it is not showing source url?

thanks

    Any idea why it is not showing source url?

    Most likely because you don’t “work at” CNN …?

    As https://developers.facebook.com/docs/graph-api/reference/video/#Reading clearly states,

    The source field will not be returned for Page-owned videos unless the User making the request has a role on the owning Page.

    I faced the same problem after the latest API changes from Facebook. The solution I came up, was to parse the video’s URL and I’m using the following function.

    function getFacebookVideoFromUrl($url) {
    $context = [
        'http' => [
        'method' => 'GET',
        'header' => "User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.47 Safari/537.36",
        ],
    ];
    $context = stream_context_create($context);
    $data = file_get_contents($url, false, $context);

    $regex = '/hd_src_no_ratelimit:"([^"]+)"/';
    if (preg_match($regex, $data, $match)) {
        return $match[1];
    } else {
        $regex = '/sd_src_no_ratelimit:"([^"]+)"/';
        if (preg_match($regex, $data, $match)) {
            return $match[1];
        }
    }

    return false;
}
