Diagnosing NS_E_DRM_UNABLE_TO_CREATE_ENCRYPT_OBJECT
0xC00D2732 is an encryption-object construction failure. It occurs before the application can encrypt protected samples, so a later media or network error should not replace the creation result in diagnostics.
Evidence that matters here
- the encryption-object creation method and the first HRESULT returned by the underlying DRM component;
- KID, selected protection algorithm and key length, recorded without exposing the key itself;
- DRM header/version and the content identity whose encryption state is being prepared;
- runtime/stub-library versions and whether a fresh parent DRM object changes the result.
Focused test
Use the same runtime to create an encryption object from a known-valid protection configuration. Then restore the original algorithm/header inputs one at a time. This separates an invalid cryptographic setup from failure to load or initialize the encryption implementation.
Correction and verification
Repair the cryptographic configuration or component initialization that prevents construction, create a new encryption object, and verify that the first sample can enter the encryption path. Do not treat successful license acquisition alone as proof that this object-creation failure is fixed.
