Members

Format

A DXGI_FORMAT structure specifying the format of the output resources.

ColorSpace

A DXGI_COLOR_SPACE_TYPE value that specifies the colorspace for the video processor output surface.

AlphaFillMode

A value from the D3D12_VIDEO_PROCESS_ALPHA_FILL_MODE enumeration specifying the alpha fill mode for data that the video processor writes to the render target.

AlphaFillModeSourceStreamIndex

The zero-based index of an input stream. This parameter is used if AlphaFillMode is D3D12_VIDEO_PROCESS_ALPHA_FILL_MODE_SOURCE_STREAM. Otherwise, the parameter is ignored.

BackgroundColor[4]

The video processor uses the background color to fill areas of the target rectangle that do not contain a video image. Areas outside the target rectangle are not affected. The meaning of the values are specified by the ColorSpace parameter.

BackgroundColor YCbCrA RGBA
BackgroundColor[0] Y R
BackgroundColor[1] Cb G
BackgroundColor[2] Cr B
BackgroundColor[3] A A

FrameRate

A DXGI_RATIONAL structure specifying the frame rate of the output video stream.

EnableStereo

If TRUE, stereo output is enabled. Otherwise, the video processor produces mono video frames.
