KSPROPERTY_CROSSBAR_PININFO_S structure (ksmedia.h)

  • Article

The KSPROPERTY_CROSSBAR_PININFO_S structure describes the crossbar pin information for a device.

Syntax

typedef struct {
  KSPROPERTY     Property;
  KSPIN_DATAFLOW Direction;
  ULONG          Index;
  ULONG          PinType;
  ULONG          RelatedPinIndex;
  KSPIN_MEDIUM   Medium;
} KSPROPERTY_CROSSBAR_PININFO_S, *PKSPROPERTY_CROSSBAR_PININFO_S;

Members

Property

Specifies an initialized KSPROPERTY structure that describes the property set, property ID, and request type.

Direction

Specifies the minidriver-provided direction of data flow for the pin specified in Index. This value can be either KSPIN_DATAFLOW_IN or KSPIN_DATAFLOW_OUT.

Index

Specifies the zero-based index of the pin for which crossbar information is being queried. Input pins are queried separately from output pins.

PinType

Specifies the minidriver-provided type of physical connector. This member must be set to one of the KS_PhysicalConnectorType enumerated values defined in ksmedia.h:

KS_PhysConn_Video_Tuner

KS_PhysConn_Video_Composite

KS_PhysConn_Video_Svideo

KS_PhysConn_Video_RGB

KS_PhysConn_Video_YRYBY

KS_PhysConn_Video_SerialDigital

KS_PhysConn_Video_ParallelDigital

KS_PhysConn_Video_SCSI

KS_PhysConn_Video_AUX

KS_PhysConn_Video_Video_1394

KS_PhysConn_Video_USB

KS_PhysConn_Video_VideoDecoder

KS_PhysConn_Video_VideoEncoder

KS_PhysConn_Video_SCART

KS_PhysConn_Audio_Tuner

KS_PhysConn_Audio_Line

KS_PhysConn_Audio_Misc

KS_PhysConn_Audio_AESDigital

KS_PhysConn_Audio_SPDIFDigital

KS_PhysConn_Audio_SCSI

KS_PhysConn_Audio_AUX

KS_PhysConn_Audio_1394

KS_PhysConn_Audio_USB

KS_PhysConn_Audio_AudioDecoder

RelatedPinIndex

Specifies the optional pin index of a pin that is related to the pin specified in Index. For example, the minidriver can set the RelatedPinIndex to the pin index of the audio stream that goes with a video stream in Index. RelatedPinIndex applies only to pins of the same direction (input or output) as the pin being queried. If no other pins are related to the current pin, the minidriver should return (-1).

Medium

Specifies a KSPIN_MEDIUM structure that represents the hardware connection for the pin. This information is returned by the minidriver.

Remarks

All index values are zero-based, and input pins are counted separately from output pins.
