VMR9SurfaceAllocationFlags Enumeration

The VMR9SurfaceAllocationFlags enumeration type is used with the IVMRSurfaceAllocator9::InitializeDevice method to specify surface creation parameters (VMR-9 only).

Syntax

typedef enum VMR9SurfaceAllocationFlags{
  VMR9AllocFlag_3DRenderTarget  = 0x0001,
  VMR9AllocFlag_DXVATarget       = 0x0002,
  VMR9AllocFlag_TextureSurface   = 0x0004,
  VMR9AllocFlag_OffscreenSurface = 0x0008,
  VMR9AllocFlag_RGBDynamicSwitch = 0x0010,
  VMR9AllocFlag_UsageReserved    = 0x00E0,
  VMR9AllocFlag_UsageMask        = 0x00FF
};

Members

VMR9AllocFlag_3DRenderTarget

Indicates that the surface is a Direct3D render target.

VMR9AllocFlag_DXVATarget

Indicates that the render target supports DXVA.

VMR9AllocFlag_TextureSurface

Indicates that the target is a Direct3D texture surface.

VMR9AllocFlag_OffscreenSurface

Indicates an offscreen surface.

VMR9AllocFlag_RGBDynamicSwitch

In YUV mixing mode, indicates that the mixer can accept RGB formats in addition to the specified YUV format. The allocator-presenter can switch between the formats dynamically. This flag is only valid in YUV mixing mode.

VMR9AllocFlag_UsageReserved

Reserved for future use.

VMR9AllocFlag_UsageMask

OR of all flags; not used by applications

Remarks

The VMR9AllocFlag_TextureSurface flag can be combined with the VMR9AllocFlag_DXVATarget and VMR9AllocFlag_3DRenderTarget flags.
