How to make video play on web by using url, but can not access by direct link?

Question 1

Ok, I understand you want to serve the video file to the script, but you don't want users being able to navigate to the video url and download/view it from there.

A quick example using PHP

Change your code to:

<script type="text/javascript">
                    jwplayer("mediaplayer1889082201").setup({
                            flashplayer: "jwplayer/jwplayer.flash.swf",
                            file: "video.php?file=coursecreeklruprr4nags7ee1codeschool_756.mp4",
                            image: "http://testhost.com/myproject/files/1/video/coursecreeklruprr4nags7ee1codeschool_756.jpg",
                            width: "800",
                            height: "510",
                            stretching: "uniform",
                            skin: "jwplayer/jwplayer-skins-free/six.xml",
                            abouttext: "myproject",
                            aboutlink: "myproject",
                    });
            </script>

As you can see, we are sending a file request to video.php, then we'll create that file serving the video only when the referrer is your webpage which will be able to show it.

Go ahead and create video.php in the same folder.

First we need to check if a file has been given in the url, like this:

<?php
if(isset($_GET['file']) {
}

Then we check if the referrer is your page, like this:

if (strpos($ref,'testhost.com/myproject/files/1') !== 0){
}

If it's your page we can start serving your file, like this:

$path = 'video/' . $_GET['file'];
header("X-Sendfile: $path");

So the whole thing together:

<?php
if(isset($_GET['file']) {
    if (strpos($ref,'testhost.com/myproject/files/1') !== 0){
        $path = 'video/' . $_GET['file'];
        header("X-Sendfile: $path");
    }
}

Look out; this is a very quick EXAMPLE, not a safe-and-ready-to-use-script! Their has to be security checks build in, and you're serving a file even when it's not existing, so that kind of checks still has to be made to make it ready for use.

Good luck with your project.

Question 2

Under:

stretching: "uniform",

Add:

type: "mp4",

This way, the JW Player can read the file if it does not have a file extension.
