从JWPlayer下载管理器缓存下载

Question

My code

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

    <script src="{{ asset('js/jwplayer.js') }}"></script>
    <script type="text/javascript">
        jwplayer("my-video").setup({
            autostart: false,
            file: "{{ asset('videos/18ThemeDetection.mp4') }}",
            image: "{{ asset('vimg/18ThemeDetection.png') }}",
            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
