This sample demonstrates how to dynamically encrypt your content with Widevine DRM. It shows how to perform the following tasks:
- Creates a transform with built-in AdaptiveStreaming preset
- Submits a job
- Creates a ContentKeyPolicy with Widevine configuration using a secret key
- Associates the ContentKeyPolicy with StreamingLocator
- Gets a token and print a url for playback
When a user requests Widevine-protected content, the player application requests a license from the Media Services license service. If the player application is authorized, the Media Services license service issues a license to the player. A Widevine license contains the decryption key that can be used by the client player to decrypt and stream the content.
