Playing Video - Server is not correctly configured - 12939

I have an ios app with laravel (lumen) on the server side. I am trying to play the videos in the server, on application.

I am using a Player that plays videos with a direct link (e.g vine video link), however when I save the same vine video on my local server, the application doesn't play the video. In fact, when I try the video with my api route, surprisingly it plays the video on Chrome! But on the application end, I receive error:

The server is not correctly configured - 12939

(Please note that if I copy the same mp4 file into the xCode project, add it on 'copy bundle resources', and try with fileWithPath, it works. So I believe it's definitely caused by the server, not vidoo file/codec. )

My route:$app->get('/player/{filename}', '[email protected]');

Methods:

public function show ($filename)
{
  $this->playVideo($filename, 'recordings');
}

public function playVideo($filename, $showType)
{
    if (file_exists("../uploads/" . $showType . "/" . $filename)) {
        $finfo = finfo_open(FILEINFO_MIME_TYPE);
        $type = finfo_file($finfo, "../uploads/" . $showType . "/" . $filename);


        header("Content-Type: " . $type);
        readfile("../uploads/" . $showType . "/" . $filename);
    }
}

To recap my problem, the video is playing on Chrome but receiving '12939' - 'Server is not correctly configured' on the mobile app.

Edit:

I tried using this as mentioned in the Apple Documentations:

curl --range 0-99 http://myapi.dev/test.mp4 -o /dev/null

However the documentation says:

"If the tool reports that it downloaded 100 bytes, the media server correctly handled the byte-range request. If it downloads the entire file, you may need to update the media server."

I received 100% and it downloaded the whole file for me, so I believe this is my problem. But I am not sure how to overcome this issue? What am I doing wrong? What should I do?

To wrap up, this solved my problem:

  • Placed this to VideoController:

    public function streamVideo() 
    {
      $video_path = 'somedirectory/somefile.mp4';
      $stream = new VideoStream($video_path);
      $stream->start(); 
    }
    
  • and then created a file in app > helpers > VideoStream.php:

     <?php
     {
         private $path = "";
         private $stream = "";
         private $buffer = 102400;
         private $start  = -1;
         private $end    = -1;
         private $size   = 0;
    
         function __construct($filePath) 
         {
             $this->path = $filePath;
         }
    
         /**

         private function open()
         {
             if (!($this->stream = fopen($this->path, 'rb'))) {
                 die('Could not open stream for reading');
             }
    
         }
