Provides a generic way to store key/value pairs on an object. The keys are GUIDs, and the values can be any of the following data types: UINT32, UINT64, double, GUID, wide-character string, byte array, or IUnknown pointer. The standard implementation of this interface holds a thread lock while values are added, deleted, or retrieved.
For a list of predefined attribute GUIDs, see Media Foundation Attributes. Each attribute GUID has an expected data type. The various "set" methods in IMFAttributes do not validate the type against the attribute GUID. It is the application's responsibility to set the correct type for the attribute.
To create an empty attribute store, call MFCreateAttributes.
The IMFAttributes interface inherits from the IUnknown interface. IMFAttributes also has these types of members:
This interface is available on the following platforms if the Windows Media Format 11 SDK redistributable components are installed:
- Windows XP with Service Pack 2 (SP2) and later.
- Windows XP Media Center Edition 2005 with KB900325 (Windows XP Media Center Edition 2005) and KB925766 (October 2006 Update Rollup for Windows XP Media Center Edition) installed.
