Sets the color-palette entries for an input stream on the video processor.
unnamedParam1hDevice [in]
A handle to the display device (graphics context).
unnamedParam2hVideoProcessor [in]
A handle to the video processor object that was created through a call to the CreateVideoProcessor function.
unnamedParam3StreamIndex [in]
The zero-based index of the input stream.
unnamedParam4Count [in]
The number of elements in the array that is referenced by the pEntries parameter.
unnamedParam5pEntries [in]
A pointer to an array of palette entries. For RGB streams, the palette entries are specified in the DXGI_FORMAT_B8G8R8A8 format. For YCbCr streams, the palette entries are specified in the DXGI_FORMAT_AYUV format.
The VideoProcessorSetStreamPalette function is called only for input streams that have a palettized color format. Palettized formats with 4 bits per pixel (bpp) use the first 16 entries in the list. Formats with 8 bpp use the first 256 entries.
If a pixel has a palette index greater than the number of entries, the device treats the pixel as white with opaque alpha. For full-range RGB, this value is (255, 255, 255, 255); for YCbCr the value is (255, 235, 128, 128).
The driver reports its ability to support palettized color formats in the D3D11_1DDI_VIDEO_PROCESSOR_CAPS structure that is returned through the GetVideoProcessorCaps function. If the driver supports the D3D11_1DDI_VIDEO_PROCESSOR_FEATURE_CAPS_ALPHA_PALETTE capability, it can be configured with color-palette entries for an input stream.
Note If the driver does not support the D3D11_1DDI_VIDEO_PROCESSOR_FEATURE_CAPS_ALPHA_PALETTE capability, the Microsoft Direct3D runtime does not call the VideoProcessorSetOutputStereoMode function.
If the driver does not report the D3D11_1DDI_VIDEO_PROCESSOR_FEATURE_CAPS_ALPHA_PALETTE capability, every palette entry must have an alpha value of 0xFF (opaque).
