Description:

The codec property value uses the wrong VARIANT type for its property GUID.

Previous	Next
MF_E_TRANSFORM_PROPERTY_PID_NOT_RECOGNIZED	MF_E_TRANSFORM_PROPERTY_NOT_WRITEABLE

MF_E_TRANSFORM_PROPERTY_VARIANT_TYPE_WRONG

MF_E_TRANSFORM_PROPERTY_VARIANT_TYPE_WRONG means the property identifier can be meaningful, but the supplied VARIANT has the wrong vt for that property. ICodecAPI explicitly defines codec configuration as GUID/value pairs whose interpretation depends on the property GUID.

Log the type tag as carefully as the numeric value

Record the property GUID and VARIANT.vt before calling the codec.
Compare the required type in the property documentation; distinguish VT_BOOL, signed and unsigned integers, arrays, and other supported forms.
Initialize and clear VARIANT values correctly so stale union data or a stale type tag is not reused.

A value such as 1 is not self-describing: boolean, 32-bit integer, and 64-bit integer variants are different contracts. Clamping the numeric payload will not fix a wrong vt.
