CSPROPERTY_VIDEOCONTROL_ACTUAL_FRAME_RATE_S (Compact 2013)
3/26/2014
This structure describes actual frame rate information in response to CSPROPERTY_VIDEOCONTROL_ACTUAL_FRAME_RATE property (see CSPROPERTY_VIDCAP_VIDEOCONTROL) requests.
Syntax
typedef struct {
CSPROPERTY Property;
ULONG StreamIndex;
ULONG RangeIndex;
SIZE Dimensions;
LONGLONG CurrentActualFrameRate;
LONGLONG CurrentMaxAvailableFrameRate;
} CSPROPERTY_VIDEOCONTROL_ACTUAL_FRAME_RATE_S, *PCSPROPERTY_VIDEOCONTROL_ACTUAL_FRAME_RATE_S;
Members
- Property
A CSPROPERTY structure that describes the property set, property ID, and request type.
- StreamIndex
A ULONG value that contains the zero-based index of the stream.
- RangeIndex
A ULON value that contains the zero-based index into the range list. The value contained at this location specifies the range in which frame rate information is being requested.
- Dimensions
A SIZE structure that specifies the width and height of the image.
- CurrentActualFrameRate
A LONGLONG value that specifies the actual frame rate for the specified stream and range. Frame rate values are expressed in 100-nanosecond units. This value is only correct if the pin is open.
- CurrentMaxAvailableFrameRate
Specifies the maximum frame rate for the specified stream and range. Frame rate values are expressed in 100-nanosecond units.
Remarks
The minidriver should return STATUS_NOT_SUPPORTED if the pin is not open.
