MFPKEY_MOST_RECENT_ENUMERATED_VBRQUALITY Property

Specifies the VBR quality level of the most recently enumerated output type. Read-only.

Constant for IPropertyBag

Available only by using IPropertyStore.

Data Type

VT_UI4

Remarks

When the encoder is acting as an Media Foundation Transform (MFT) and it enumerates an output type on a call to IMFTransform::GetOutputAvailableType, you can query the MFT for the MFPKEY_MOST_RECENTLY_ENUMERATED_VBRQUALITY property. The value returned indicates the VBR quality of the most recently returned output media type. Then you can use that value to set the MFPKEY_DESIRED_VBRQUALITY property of the encoder.
