KSPROPERTY_VIDEOCOMPRESSION_GETINFO_S structure (ksmedia.h)
The KSPROPERTY_VIDEOCOMPRESSION_GETINFO_S structure describes information about the video compression capabilities supported by a device.
Syntax
typedef struct {
KSPROPERTY Property;
ULONG StreamIndex;
LONG DefaultKeyFrameRate;
LONG DefaultPFrameRate;
LONG DefaultQuality;
LONG NumberOfQualitySettings;
LONG Capabilities;
} KSPROPERTY_VIDEOCOMPRESSION_GETINFO_S, *PKSPROPERTY_VIDEOCOMPRESSION_GETINFO_S;
Members
Property
Specifies an initialized KSPROPERTY structure that describes the property set, property ID, and request type.
StreamIndex
Specifies the zero-based index of the stream being queried.
DefaultKeyFrameRate
Indicates the estimated number of frames per key frame.
DefaultPFrameRate
Indicates the predicted number of frames per key frame.
DefaultQuality
Specifies the default quality value. This value should be in the range from 0 through 10000.
NumberOfQualitySettings
Indicates the number of discrete compression quality settings the device supports.
Capabilities
Specifies the compression capabilities of the device. This member can be one or more (logically ORed) of the values from the KS_CompressionCaps enumeration.
