CSPROPERTY_PIN (Windows Embedded CE 6.0)

1/6/2010

This enumeration provides values that represent the properties in the CSPROPERTY_Pin property set. They describe the types of property queries that can be made for a camera pin.

Syntax

typedef enum {
  CSPROPERTY_PIN_CINSTANCES = 0,
  CSPROPERTY_PIN_CTYPES,
  CSPROPERTY_PIN_DATARANGES,
  CSPROPERTY_PIN_DATAINTERSECTION,
  CSPROPERTY_PIN_CATEGORY,
  CSPROPERTY_PIN_NAME,
} CSPROPERTY_PIN;

Elements

• CSPROPERTY_PIN_CINSTANCES
  Used to query for the current number of pins this pin factory has instantiated, as well as the maximum number of pins this pin factory can instantiate, per filter.

  This property returns a structure of type CSPIN_CINSTANCES.

  This property specifies the per-filter maximum for a given pin factory.

  Stream minidrivers do not need to handle this property directly; the stream class driver handles this property using stream request blocks to query for more information.

• CSPROPERTY_PIN_CTYPES
  Used to query the camera driver for the number of pin types it supports.

  This property returns a value of type ULONG, specifying the number of pin factories the CS filters it supports.

  Stream minidrivers do not need to handle this property directly; the stream class driver handles this property using stream request blocks to query for more information.

• CSPROPERTY_PIN_DATARANGES
  Used to determine the data ranges supported by pins instantiated by the pin factory. For more information, see Video Format Negotiation.

  Specify this property using CSP_PIN, where the PinId member specifies the pin factory for which to return acceptable data ranges.

  CS filters return all data ranges supported by pins instantiated by the pin factory. A CS filter may not support a reported data range in its current internal state.

  Stream minidrivers do not need to handle this property directly; the stream class driver handles this property using stream request blocks to query for more information.

• CSPROPERTY_PIN_DATAINTERSECTION
  Used to find a data format supported by pins instantiated by the pin factory. The client supplies a list of data formats; the CS filter returns the first data format on the list that is supported.

  To specify this property, provide a CSP_PIN structure followed by a CSMULTIPLE_ITEM structure and a sequence of 64-bit aligned CSDATARANGE structures. The value in CSP_PIN.PinId specifies the pin factory.

  This property returns the first matching data format from the client-supplied list.

  Stream minidrivers do not need to handle this property directly; the stream class driver handles this property using stream request blocks to query for more information.

• CSPROPERTY_PIN_CATEGORY
  Used to query the camera driver for a pin's type (preview, capture, or still).

  The PinId member of the CSP_PIN structure specifies the pin factory for which to return the category GUID.

  The CS filter uses this property to indicate the standard functional category of pins instantiated by the pin factory.

  Stream minidrivers do not need to handle this property directly; the stream class driver handles this property using stream request blocks to query for more information where necessary.

• CSPROPERTY_PIN_DEVICENAME
  Used to query the camera driver for a pin's name. Drivers can assign any name to a pin, but typically the name will be PIN1:.

  Specify this property using CSP_PIN, where the member specifies the pin factory for which to return the registry name.

  Stream minidrivers do not need to handle this property directly; the stream class driver handles this property using stream request blocks to query for more information.
