MF_E_HDCP_AUTHENTICATION_FAILURE
MF_E_HDCP_AUTHENTICATION_FAILURE means HDCP did not reach an authenticated link state. This is an establishment failure, distinct from a protected link that authenticated successfully and then broke during playback.
Capture the physical output and HDCP state at authentication time
- Record the graphics adapter, output connector, display, dock or receiver, and every repeater in the path.
- Query Output Protection Manager status and actual protection level where the application has that diagnostic path; preserve flags that identify disabled outputs or revoked HDCP devices.
- Compare direct display connection with the same content routed through a dock, AV receiver, KVM, or adapter to isolate the failing HDCP topology.
The HDCP specification separates Authentication and Key Exchange, locality checking, session-key exchange, and repeater topology processing. Certificate verification, revocation checks, protocol timeouts, and cryptographic mismatches can abort authentication before encrypted content flows. A generic decoder reinstall does not address this stage. Keep this HRESULT separate from MF_E_HDCP_LINK_FAILURE, which reports failure after the link was already established.
