Related D3D11_1DDI_VIDEO_DECODERR_BUFFER_DESC structure has both fields but the Members section has…
It might look weird why would someone try Direct3D mode with a DSP, which is not supposed to be Direct3D aware, but still. I am omitting the part why I even got to such scenario. The documentation says a few things about MFT_MESSAGE_SET_D3D_MANAGER: This message applies only to video transforms. The client should not send…
