Download manager caching downloads from JWPlayer

My code

    <div id="my-video"></div>

    <script src=""></script>
    <script type="text/javascript">
        jwplayer("my-video").setup({
            autostart: false,
            file: "",
            image: "",
            width: "1000",
            height: "700",
            primary: "html",
        });
    </script>

In this, my download manager is downloading the file. How can I protect video from downloading?

Is it right what I am doing? or need to change something

Please help. Thank you
