IKsPin interface (ksproxy.h)

The IKsPin interface provides methods that control and retrieve information about a pin.

The IID for this interface is IID_IKsPin.

Inheritance

The IKsPin interface inherits from the IUnknown interface.

The IKsPin interface has these methods.


IKsPin::KsCreateSinkPinHandle The KsCreateSinkPinHandle method creates a pin handle and stores it in the KS pin object.
IKsPin::KsDecrementPendingIoCount The KsDecrementPendingIoCount method decrements the number of input/output (I/O) operations that are in progress on a pin.
IKsPin::KsDeliver The KsDeliver method delivers a media sample from an output pin to an input pin, continues an I/O operation by retrieving the next buffer from an allocator, and submits the buffer to the associated device.
IKsPin::KsGetCurrentCommunication The KsGetCurrentCommunication method retrieves the current communication direction, interface, and medium of a pin.
IKsPin::KsIncrementPendingIoCount The KsIncrementPendingIoCount method increments the number of input/output (I/O) operations that are in progress on a pin.
IKsPin::KsMediaSamplesCompleted The KsMediaSamplesCompleted method informs a pin that a stream segment completed.
IKsPin::KsPeekAllocator The KsPeekAllocator method returns a pointer to an IMemAllocator interface for a pin's assigned allocator.
IKsPin::KsPropagateAcquire The KsPropagateAcquire method directs all the pins on the filter to attain the Acquire state.
IKsPin::KsQueryInterfaces The KsQueryInterfaces method retrieves interfaces that a pin supports.
IKsPin::KsQueryMediums The KsQueryMediums method retrieves mediums that a pin supports.

An interface handler (IKsInterfaceHandler) uses many of the IKsPin methods to route media samples of a particular media type.
