The IKsDataTypeCompletion interface provides a method to complete partially specified media types that are passed to the IAMStreamConfig::SetFormat method.
The IID for this interface is IID_IKsDataTypeCompletion.
The IKsDataTypeCompletion interface inherits from the IUnknown interface.
In order to keep the proxy data type neutral, optional data type handlers can be loaded to massage the data stream as it passes to or from kernel-mode filters. You should implement a data type handler as a COM server that, at least, supports the IKsDataTypeHandler interface. The IKsDataTypeCompletion interface is optional for data type handlers. A data type handler only supports IKsDataTypeCompletion if the media format has a partially specified form.
A data type handler is typically loaded during the pin connection process, and unloaded when the connection is broken. However, a data type handler is sometimes loaded briefly for other purposes. For instance, if an application uses DirectShow's IAMStreamConfig::SetFormat method, the application possibly uses a data type handler to complete a partial media type parameter returned from IAMStreamConfig::SetFormat. For more information about IAMStreamConfig::SetFormat, see the Microsoft Windows SDK documentation.
