MFT_ENUM_HARDWARE_URL_Attribute attribute

Contains the symbolic link for a hardware-based Media Foundation transform (MFT).

Data type



To get this attribute, call IMFAttributes::GetString.

To set this attribute, call IMFAttributes::SetString.


This attribute is supported by hardware-based MFTs. The value of the attribute is the symbolic link for the device driver. This attribute is also set on the IMFActivate pointers allocated by the MFTEnumEx function, when those pointers represent hardware-based MFTs.

The symbolic link should be considered an opaque string. To get the display name for a device, query the MFT_FRIENDLY_NAME attribute.

Software MFTs should not have this attribute set.

The GUID constant for this attribute is exported from mfuuid.lib.
