Members

Property
An initialized CSPROPERTY structure that that describes the property set, property ID, and request type.

StreamIndex
A ULONG value that Specifies the zero-based index of the stream being queried.

DefaultKeyFrameRate
A LONG value that indicates the estimated number of frames per key frame.

DefaultPFrameRate
A LONG value that indicates the predicted number of frames per key frame.

DefaultQuality
A LONG value that specifies the default quality value. This value should be in the range from 0 through 10000.

NumberOfQualitySettings
A LONG value that 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 CS_CompressionCaps enumeration.
