Video Playback - Server Not Configured - 12939

Question

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

I use Player, which plays a video with a direct link (for example, a video for videos), however, when I save the same video on your local server, the application does not play the video. In fact, when I try the video using my api route, it is amazing that it plays the video on Chrome! But at the end of the application, I get an error message:

Server is configured incorrectly - 12939

(Note that if I copy the same mp4 file to the xCode project, add it to the "instance package resources" and try with theWithPath file, it works. Therefore, I believe this is definitely caused by the server, not the vidoo file / codec .)

My route: $app->get('/player/{filename}', 'PlayerController@show');

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 reproduce my problem, the video plays in Chrome, but gets "12939" - "Server is not configured correctly" in the mobile application.

Edit:

I tried using this as stated in 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 processed the request for a byte range. If it downloads the entire file, you may need to update the media server."

100%, , , . , ? ? ?

• VideoController:

  public function streamVideo() 
  {
    $video_path = 'somedirectory/somefile.mp4';
    $stream = new VideoStream($video_path);
    $stream->start();
