MFT_CODEC_MERIT_Attribute attribute
Contains the merit value of a hardware codec.
Data type
UINT32
Get/set
To get this attribute, call IMFAttributes::GetUINT32.
To set this attribute, call IMFAttributes::SetUINT32.
Remarks
This attribute is set on the activation object for a Media Foundation transform (MFT) that represents a hardware codec. The value of the attribute is the codec's merit value.
This attribute controls the order in which the MFTEnumEx function enumerates codecs, if the MFT_ENUM_FLAG_SORTANDFILTER flag is set. MFTs with a merit value appear higher in the list than other MFTs.
This attribute does not contain a trusted value. To verify the codec's actual merit value, call the MFGetMFTMerit function.
If the value of the MFT_CODEC_MERIT_Attribute attribute does not match the merit value retrieved by MFGetMFTMerit, the IMFActivate::ActivateObject method fails and returns MF_E_INVALID_CODEC_MERIT.
The GUID constant for this attribute is exported from mfuuid.lib.
