Video Upload on Imgur PHP - php

Question

I'm currently working on an Imgur API which should upload images, gifs and videos; images and gifs are being uploaded without any problems and are working fine.
My Problem is the video part, I always get an error similar to this:
{"data":{"error":"No image data was sent to the upload
api","request":"\/3\/upload","method":"POST"},"success":false,"status":400}
or this:
Notice: Undefined index: link in C:\xampp\htdocs\localfile\php\upvideo.php on line 50 There's a Problem No image data was sent to the upload api
or I get an timeout response.
Since the API docs told me that I need to post it as a Binaryfile I tried using fopen(), fread(), file_get_contents() and countless more. Sadly none of them seem to give curl the string it wants if I use a video; it works just fine with images and gifs (which are now being sent as binary - before I used base64encode before passing it to curl).
I do know that there are 2 tags video and image which I change based on what I'm trying to send at the moment, but video always seems to give me the errors above.
Here is my code:
<?php
// the posted stuff from my form
$title = htmlspecialchars($_POST["title"]);
$posted = htmlspecialchars($_POST["token"]);
$desc = htmlspecialchars($_POST["desc"]);
// data from the file i put into the form
$fileName = $_FILES["imglink"]["name"];
$fileTmpName = $_FILES["imglink"]["tmp_name"];
$size = $_FILES["imglink"]["size"];
// checks if everything is set and ready
if ($title != "" && $desc != "" && is_string($posted)) {
if($fileName == ''){
header("location: ../sub-pages/error.php?noimage");
}else{
/*$data = file_get_contents($fileTmpName);*/
/*var_dump($data);*/
// take the file temporary name and make it something binary..
$handle = fopen($fileTmpName, "rb");
$data = fread($handle, filesize($fileTmpName));
//the curl function
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_SSL_VERIFYHOST => 0,
CURLOPT_SSL_VERIFYPEER => 0,
CURLOPT_URL => "https://api.imgur.com/3/upload",
CURLOPT_RETURNTRANSFER => TRUE,
CURLOPT_ENCODING => "",
CURLOPT_POST => 1,
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => false,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
// all the files i need imgur to get e.g the video (i change video to image if i want to post an image), name of the image etc.
CURLOPT_POSTFIELDS => array( 'video' => # $data, "type" => "file", "title" => $title, "description" => $desc, "name" => $fileName),
CURLOPT_HTTPHEADER => array( "Authorization: Bearer ". $posted),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
$pms = json_decode($response, true);
$url = $pms['data']['link'];
if ($url!="") {
echo "Posted";
header("location: ../sub-pages/succes.php?link=". $url);
} else {
echo "<h2>There's a Problem</h2>";
echo $pms['data']['error'];
}
}
}
else{
echo "no";
}?>
