Prevent HTML5 video from being downloaded (right-click saved)?

Question

How can I disable \"Save Video As...\" from a browser\'s right-click menu to prevent clients from downloading a video?

Are there more complete solutions that prevent

Answer 1

PHP sends the html5 video tag together with a session where the key is a random string and the value is the filename.

ini_set('session.use_cookies',1);
session_start();
$ogv=uniqid(); 
$_SESSION[$ogv]='myVideo.ogv';
$webm=uniqid(); 
$_SESSION[$webm]='myVideo.webm';
echo ''; 

Now PHP is asked to send the video. PHP recovers the filename; deletes the session and sends the video instantly. Additionally all the 'no cache' and mime-type headers must be present.

ini_set('session.use_cookies',1);
session_start();
$file='myhiddenvideos/'.$_SESSION[$_GET['video']];
$_SESSION=array();
$params = session_get_cookie_params();
setcookie(session_name(),'', time()-42000,$params["path"],$params["domain"],
                                         $params["secure"], $params["httponly"]);
if(!file_exists($file) or $file==='' or !is_readable($file)){
  header('HTTP/1.1 404 File not found',true);
  exit;
  }
readfile($file);
exit:

Now if the user copy the url in a new tab or use the context menu he will have no luck.
