PHP only allow certain users access to video files in directory's

for my current project i need a folder that contains videos which should only be seeable for registered users, i know that i can block the access via .htaccess file but at least i dont exactly get what i want..

my currently .htaccess file is like this:

Deny from all 

at the moment im importing the videos/pictures through php which works for accessing them but its really really slow..

here is an example for my pictures:

<img src="data:image/png;base64,<?php echo base64_encode(file_get_contents("directory")) ?>">

and here for my videos:

<img src="data:video/mp4;base64,<?php echo base64_encode(file_get_contents("directory")) ?>">

im sure there is a better way where the page doesnt take forever to load, i also tried a video stream with php but i get another problem there, i cant leave the page anymore or again like before it takes forever to click links or leave.. :(

help is much appreciated!
