Members

Rotation

Specifies the clockwise rotation of the overlay plane.

RotationWithoutIndependentFlip

When TRUE, indicates that the driver can perform plane rotation of 90, 180, or 270 degrees, but IndependentFlip cannot be used when rotating the plane.

VerticalFlip

The overlay plane should flip the data vertically.

HorizontalFlip

The overlay plane should flip the data horizontally.

StretchRGB

When TRUE, the hardware supports stretching any plane containing RGB data.

StretchYUV

When TRUE, the hardware supports stretching any plane containing YUV data.

BilinearFilter

When TRUE, the hardware supports bilinear filtering.

HighFilter

When TRUE, the hardware supports better than bilinear filtering.

Shared

When TRUE, the multiplane overlay resources reported by the capabilities are shared across all VidPn sources.

When FALSE, the multiplane overlay resources reported by capabilities are dedicated to the specific VidPn source.

Immediate

When TRUE, the HW supports immediate flips of the MPO plane.

If the flip contains changes that cannot be performed as an immediate flip, the driver can promote the flip to a VSYNC flip using the new HSync completion infrastructure.

Plane0ForVirtualModeOnly

When TRUE, the hardware will always apply the stretch factor of plane 0 to the hardware cursor as well as the plane. This implies that stretching/shrinking of plane 0 should only occur when plane 0 is the desktop plane and when the stretching/shrinking is used for virtual mode support.

Version3DDISupport

Driver supports the WDDM 2.2 MPO (multi-plane overlay) DDIs.

Reserved

Reserved for internal use.

Value

The value used to operate over the other members.
