Remarks

An implementation of a Content Decryption Module (CDM) may include an implementation of IMFInputTrustAuthority obtained by calling CreateTrustedInput.

The following attributes are supported for IMFInputTrustAuthority decrypter.

Property Description
MFT_POLICY_SET_AWARE If non-zero, indicates that the IMFTransform wants to receive MEPolicySet completion notifications.
MFT_USING_HARDWARE_DRM Specifies whether the IMFTransform is using hardware DRM. If an MFT decrypter specifies this attribute set to 1, then it is using hardware DRM. If an MFT decrypter specifies this attribute set to 0, then it is not using hardware DRM. If an MFT decrypter does not specify this attribute or specifies it with a different value, then it does not (or is unable to) indicate whether it is using hardware DRM.
