CSPROPERTY_VIDEOCOMPRESSION_GETINFO_S (Windows Embedded CE 6.0)

1/6/2010

This structure describes information about the video compression capabilities supported by a device.

Syntax

typedef struct {
  CSPROPERTY Property;
  ULONG      StreamIndex;
  LONG       DefaultKeyFrameRate;
  LONG       DefaultPFrameRate;
  LONG       DefaultQuality;
  LONG       NumberOfQualitySettings;
  LONG       Capabilities;
} CSPROPERTY_VIDEOCOMPRESSION_GETINFO_S,
*PCSPROPERTY_VIDEOCOMPRESSION_GETINFO_S;

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.
