Pull request overview
This PR adds an end-to-end API (wrapper → server service → IPC → client) to query the robustness levels supported by the underlying CDM for a given key system, enabling WebKit (and other consumers) to determine DRM robustness (e.g., Widevine L1 support).
Changes:
- Added
getSupportedRobustnessLevelsto the public/media capabilities interfaces and implementations (client + server). - Extended the MediaKeysCapabilities IPC protobuf/service with a new
getSupportedRobustnessLevelsRPC. - Implemented the OpenCDM wrapper call to retrieve supported robustness levels from the CDM.
