• How to implement Clear-Key video encryption in PHP and play it in HTML [closed]

  22 octobre 2018, par Ali Farhoudi

  I want to implement video encryption in php and play encrypted video in HTML5 video. I have read some documents about it :

  • https://en.wikipedia.org/wiki/Encrypted_Media_Extensions
  • https://w3c.github.io/encrypted-media/

  And I know there are alternative tools and services that I can use :

  • https://support.uplynk.com/tut_embedding_the_uplynk_player_3.html
  • https://www.wowza.com/products/capabilities/streaming-content-security
  • https://www.intertrust.com/products/drm-system/livestream/
  • https://bitmovin.com/cenc-widevine-drm/
  • https://www.html5rocks.com/en/tutorials/eme/basics/

  I want to provide like this example :

  • https://demo.castlabs.com/ (play big buck bunny smooth streaming : that can’t be downloaded and the url is one-time usable)

  What steps should I pass ?
  I use PHP (laravel) in server-side.
