In Electron you can use the Widevine CDM library shipped with Chrome browser.
|
|
|
|
|
|
+Widevine Content Decryption Modules (CDMs) are how streaming services protect
|
|
|
+content using HTML5 video to web browsers without relying on an NPAPI plugin
|
|
|
+like Flash or Silverlight. Widevine support is an alternative solution for
|
|
|
+streaming services that currently rely on Silverlight for playback of
|
|
|
+DRM-protected video content. It will allow websites to show DRM-protected video
|
|
|
+content in Firefox without the use of NPAPI plugins. The Widevine CDM runs in an
|
|
|
+open-source CDM sandbox providing better user security than NPAPI plugins.

|
+#### Note on VMP
|
|
|
+
|
|
|
+As of [`Electron v1.8.0 (Chrome v59)`](https://electronjs.org/releases#1.8.1),
|
|
|
+the below steps are may only be some of the necessary steps to enable Widevine;
|
|
|
+any app on or after that version intending to use the Widevine CDM may need to
|
|
|
+be signed using a license obtained from [Widevine](https://www.widevine.com/)
|
|
|
+itself.
|
|
|
+
|
|
|
+Per [Widevine](https://www.widevine.com/):
|
|
|
+
|
|
|
+> Chrome 59 (and later) includes support for Verified Media Path (VMP). VMP
|
|
|
+> provides a method to verify the authenticity of a device platform. For browser
|
|
|
+> deployments, this will provide an additional signal to determine if a
|
|
|
+> browser-based implementation is reliable and secure.
|
|
|
+>
|
|
|
+> The proxy integration guide has been updated with information about VMP and
|
|
|
+> how to issue licenses.
|
|
|
+>
|
|
|
+> Widevine recommends our browser-based integrations (vendors and browser-based
|
|
|
+> applications) add support for VMP.
|
|
|
+
|
|
|
+To enable video playback with this new restriction,
|
|
|
+[castLabs](https://castlabs.com/open-source/downstream/) has created a
|
|
|
+[fork](https://github.com/castlabs/electron-releases) that has implemented the
|
|
|
+necessary changes to enable Widevine to be played in an Electron application if
|
|
|
+one has obtained the necessary licenses from widevine.
