Unable to upload video to user's facebook account using Graph API - php

Question

I have created a facebook app in last month.
I am trying to upload a video from my PHP code, but it throws an error that (#353) You must select a video file to upload. While I tried to upload the same video from my Facebook account directly and it gets uploaded properly.
I don't know what is wrong things that exists, PHP code is as below
$api="/me/videos";
$uploaded_videos=$facebook->api($api);
$video_file_path=$user_dir_abs_path."/NewProject20.mov";
if(file_exists($video_file_path))
{
echo "file exists...";
}else{
die("not exist");
}
$ret_obj = $facebook->api('/me/videos', 'POST', array(
'source' => '#' . $video_file_path,
'title' => "This is just a test",
'description' => 'test9000',
'privacy' => json_encode(array('value' => 'EVERYONE' )),
)
);
echo '<pre>'. $ret_obj.'</pre>';
Video I have uploaded is here
Document I refer to code is here
https://developers.facebook.com/blog/post/493/
https://developers.facebook.com/blog/post/608/
I have used following code as well, but I am getting that same error..
$id=$facebook->getUser(); /* UID of the connected user */
$api="/".$id."/videos";
echo "api -> $api";
/*$ret_obj = $facebook->api('/me/videos', 'POST', array(*/
$ret_obj = $facebook->api($api, 'POST', array(
'source' => '#' . $video_file_path,
'title' => "This is just a test",
'description' => 'test9000',
'privacy' => json_encode(array('value' => 'EVERYONE' )),
)
);
echo '<pre>'. $ret_obj.'</pre>';

From your comments, I got to know that you need to upload/post a video from your server to facebook, instead form posting method specified in documentation.
I don't know much about facebook-sdk, I would suggest you to use CURL method instead.
<?php
$app_id = "XXXXXXXXXXXXXX";
$app_secret = "XXXXXXXXXXXXXXXXXXXXXXX";
$my_url = "http://localhost/url_of_this_page.php";
$video_title = "Video title here";
$video_desc = "Video description here";
$code = $_REQUEST["code"];
if(empty($code)) {
$dialog_url = "http://www.facebook.com/dialog/oauth?client_id="
. $app_id . "&redirect_uri=" . urlencode($my_url)
. "&scope=publish_stream";
echo("<script>top.location.href='" . $dialog_url . "'</script>");
}
$token_url = "https://graph.facebook.com/oauth/access_token?client_id="
. $app_id . "&redirect_uri=" . urlencode($my_url)
. "&client_secret=" . $app_secret
. "&code=" . $code;
$access_token = file_get_contents($token_url);
$post_url = "https://graph-video.facebook.com/me/videos?"
. "title=" . $video_title. "&description=" . $video_desc
. "&". $access_token;
$ch = curl_init();
$data = array('name' => 'file', 'file' => '#'.realpath("ipad.mp4"));// use realpath
curl_setopt($ch, CURLOPT_URL, $post_url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$res = curl_exec($ch);
if( $res === false ) {
echo curl_error($ch);
}
curl_close($ch);
?>
As a response from facebooks, you'l get video id like:
{"id":"892161284142980"}

Answer 2

Have a look at https://developers.facebook.com/docs/graph-api/reference/v2.0/user/videos/#publish
Videos must be encoded as multipart/form-data and published to
graph-video.facebook.com instead of the regular Graph API URL.

If anyone is still having issue uploading videos via the facebook sdk4 api, the below code worked for me:
$file_name = "/absolute/path/to/file/in/directory";
$linkData = [
'source' => new \CURLFile($file_name, 'video/m4v'),
'message' => 'Your message',
];
$ret_obj = $facebook->api('/me/videos', 'POST', $linkData);
