Laravel stream a video from own hard drive

I am building an app to organaize, manage and play a family film collection of about 700 films with Laravel5 that should be capable to play the films in format MP4.

In my HTML code I have the following code:

<video width="100%" height="360" controls>
    <source src="http://my-domain.com/films/xanadu.mp4" type="video/mp4">
</video>

However, I can't upload 700 films to a hosting space (not to mention the copyright problems). So I decided to store locally and play films from my hard drive. So, I have created a directory under public and add there a film, like this:

my-app
    public
        films
            xanadu.mp4

and changed the code to

<video width="100%" height="360" controls>
    <source src="" type="video/mp4">
</video> 

Inspecting the element I get the right address:

http://family-film.test/films/xanadu.mp4

But I get the error:

No video with supported format and MIME type found.

So, I wonder if there is any error in my code or it is just technically ipossible to stream a video from the own hard drive using the HTML5 video tag
