MF_E_ITA_UNRECOGNIZED_ANALOG_VIDEO_PROTECTION_GUID
MF_E_ITA_UNRECOGNIZED_ANALOG_VIDEO_PROTECTION_GUID is a schema-identity failure in WMDRM output policy. Media Foundation represents output protection systems by GUID, and an IMFOutputSchema couples that schema type with its configuration data.
Log the GUID before policy data is transformed
- Record the exact analog-video protection GUID supplied by the license/policy path.
- Trace which ITA or custom protection component produced the corresponding policy object.
- Check for stale SDK constants, corrupted serialized GUID bytes, or accidental use of a digital-output schema in the analog path.
This code is more specific than MF_E_POLICY_UNSUPPORTED. The WMDRM ITA cannot identify the requested analog protection mechanism, so capability negotiation with an OTA has not simply failed on a known schema. Do not substitute an arbitrary protection GUID. The schema identity is part of protected-content policy and must come from a compatible protection implementation.
