PHP Accessing and loading video via samba - php

Question

I got a pretty specific question. I'm accessing data via samba on distant server and I got no choice. To achieve that in php I use a php wrapper for smbclient from GitHub https://github.com/icewind1991/SMB. I got a piece of code that works to load the video and play it but the problem is that I want to be able to navigate through the timeline and for it to play as soon as there is data to be read.. I repeat that I can't access data any other way and I use that library for other parts of my website so I can't change it. Right now it reads all the data from the whole video before playing it and I can't use the slider to navigate through the timeline. There's my code sample with false authentication data for the samba access.
<?php
require('../../class/SMB-master/vendor/autoload.php');
$host = '0.0.0.0';
$user = 'user';
$workgroup = 'workgroup.lan';
$password = 'password';
$share = 'share/'.$_GET["filePath"].'';
$auth = new \Icewind\SMB\BasicAuth($user, $workgroup, $password);
$serverFactory = new \Icewind\SMB\ServerFactory();
$server = $serverFactory->createServer($host, $auth);
$share = $server->getShare($share);
//Reads PDF 4096 bytes by 4096 bytes until there is no more data to read if the format is pdf
if($_GET['openFile'] == 'PDF')
{
$charNumber = 20;
$result = bin2hex(random_bytes($charNumber));
header("Content-type:application/pdf");
header("Content-Disposition:inline;filename=".$result.".pdf");
$fh = $share->read($_GET['name']);
while ($data = fread($fh, 4096))
echo $data;
fclose($fh);
}
else{
//Reads video 4096 bytes by 4096 bytes until there is no more data to read if the format is video mp4
header("Content-type:video/mp4");
header("Content-Disposition:inline;filename=".$_GET['name']."");
$fh = $share->read($_GET['name']);
while ($data = fread($fh, 4096)){
echo $data;
}
fclose($fh);
}
