DRM support

Play protected content through EME while keeping key-system policy and license transport configurable by the adapter.

Proposed direction

• Probe key-system and robustness compatibility before protected-track selection.
• Keep media-key attachment, session lifecycle, and license exchange separate.
• Expose application hooks for credentials, headers, certificates, and errors.
• Clean up sessions and pending requests on source replacement.

Before implementation

Choose the first supported key systems and manifest signaling. Specify persistent-session policy, renewal, output restrictions, and error contracts. Test source replacement and clear/encrypted transitions.
