The VMRMixerPrefs enumeration contains flags that specify decimation, filtering, and color space information that will be used when the video image is created on the DirectDraw surface.

Members
MixerPref_NoDecimation
Indicates that the video will be rendered onto the surface in its native size.
MixerPref_DecimateOutput
Indicates that the native video will be decimated by a factor of 2 in both x and y directions.
MixerPref_DecimateMask
Used internally by the VMR to isolate the fields relevant to each parameter being set. Should not be used by applications.
MixerPref_BiLinearFiltering
Indicates that bi-linear filtering will be used. This is the default type of filtering, but not all cards can support it.
MixerPref_PointFiltering
Indicates that point filtering will be used.
MixerPref_FilteringMask
Used internally by the VMR to isolate the fields relevant to each parameter being set. Should not be used by applications.
MixerPref_RenderTargetRGB
Indicates that the render target is an RGB surface.
MixerPref_RenderTargetYUV420
Indicates that the render target is a YUV 4:2:0 surface.
MixerPref_RenderTargetYUV422
Indicates that the render target is a YUV 4:2:2 surface.
MixerPref_RenderTargetYUV444
Indicates that the render target is a YUV 4:4:4 surface.
MixerPref_RenderTargetReserved
Reserved for future use.
MixerPref_RenderTargetMask
Used internally by the VMR to isolate the fields relevant to each parameter being set. Should not be used by applications.
