IMFAttributes::SetItem method

Adds an attribute value with a specified key.

Syntax


HRESULT SetItem(
  [in] REFGUID        guidKey,
  [in] REFPROPVARIANT Value
);

Parameters

guidKey [in]

A GUID that identifies the value to set. If this key already exists, the method overwrites the old value.

Value [in]

A PROPVARIANT that contains the attribute value. The method copies the value. The PROPVARIANT type must be one of the types listed in the MF_ATTRIBUTE_TYPE enumeration.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return codeDescription
S_OK

The method succeeded.

E_OUTOFMEMORY

Insufficient memory.

MF_E_INVALIDTYPE

Invalid attribute type.

 

Remarks

This method checks whether the PROPVARIANT type is one of the attribute types defined in MF_ATTRIBUTE_TYPE, and fails if an unsupported type is used. However, this method does not check whether the PROPVARIANT is the correct type for the specified attribute GUID. (There is no programmatic way to associate attribute GUIDs with property types.) For a list of Media Foundation attributes and their data types, see Media Foundation Attributes.
