How to set the video process parameter for DXGI_FORMAT_B8G8R8X8_UNORM to DXGI_FORMAT_B8G8R8A8_UNORM

    Question

  • I have one texture2d with DXGI_FORMAT_B8G8R8X8_UNORM format and want it change to DXGI_FORMAT_B8G8R8A8_UNORM format when I use VideoProcessorBlt function. The alpha values always

    be 0x00, I want it to be 0xff. I tried VideoProcessorSetStreamAlpha and VideoProcessorSetOutputAlphaFillMode and still cannot get the 0xff.

  • Thank you very much! Any feedback now? I have used pixel shader to modify the alpha value ,but this method is not good. Looking forward to your response.
