IKsDataTypeCompletion interface (ksproxy.h)
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.
Inheritance
The IKsDataTypeCompletion interface inherits from the IUnknown interface.
Methods
The IKsDataTypeCompletion interface has these methods.
| IKsDataTypeCompletion::KsCompleteMediaType The KsCompleteMediaType method completes a partially-specified media type that was first presented to the IAMStreamConfig::SetFormat method. |
Remarks
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.
