Web Drm Configuration
class WebDrmConfiguration(val licenseUrl: String, licenseRequestHeaders: Map<String, String> = emptyMap())
Runtime-only DRM configuration for the WebAssembly player.
The license URL and request headers are passed only to the license request made by Movi/Shaka. They are never reused as media request headers. toString deliberately redacts all values so accidental logging cannot expose license endpoints or credentials.
