KSPROPERTY_CAMERACONTROL_NODE_S2 structure (ksmedia.h)
The KSPROPERTY_CAMERACONTROL_NODE_S2 structure describes node-based properties in the PROPSETID_VIDCAP_CAMERACONTROL property set that use two values at the same time. This structure specifies property values in requests to the USB video class driver.
Syntax
typedef struct {
KSP_NODE NodeProperty;
LONG Value1;
ULONG Flags;
ULONG Capabilities;
LONG Value2;
} KSPROPERTY_CAMERACONTROL_NODE_S2, *PKSPROPERTY_CAMERACONTROL_NODE_S2;
Members
NodeProperty
Specifies an initialized KSP_NODE structure that describes the property set, property ID, request type, and node ID.
Value1
Specifies the first value of the property. This member is read/write.
Flags
Indicates, for get requests, the current setting for the specified property from the values listed below. Indicates, for set requests, the desired setting for the specified property from the values listed below. This member can be set to one of the following values that are defined in ksmedia.h:
Flag | Meaning |
---|---|
KSPROPERTY_CAMERACONTROL_FLAGS_MANUAL | Indicates that the setting is controlled manually |
KSPROPERTY_CAMERACONTROL_FLAGS_AUTO | Indicates that the setting is controlled automatically |
KSPROPERTY_CAMERACONTROL_FLAGS_ABSOLUTE | Indicates that the setting is in absolute values |
KSPROPERTY_CAMERACONTROL_FLAGS_RELATIVE | Indicates that the setting is in relative values |
Capabilities
Indicates the minidriver's camera control capabilities for the specified property. This member is read-only. This member can be set to one of the following values that are defined in ksmedia.h:
Flag | Meaning |
---|---|
KSPROPERTY_CAMERACONTROL_FLAGS_MANUAL | Indicates that the device can be controlled manually |
KSPROPERTY_CAMERACONTROL_FLAGS_AUTO | Indicates that the device can be controlled automatically |
KSPROPERTY_CAMERACONTROL_FLAGS_ABSOLUTE | Indicates that the device settings are in absolute values |
KSPROPERTY_CAMERACONTROL_FLAGS_RELATIVE | Indicates that the device settings are in relative values |
Value2
Specifies the second value of the property. This member is read/write.
Remarks
This structure is used by KSPROPERTY_CAMERACONTROL_PANTILT and KSPROPERTY_CAMERACONTROL_PANTILT_RELATIVE for node-based get/set property requests.
