I’m currently running a system with a GRID K1 card running driver version 347.25. I am able to run all the DX samples provided by the GRID SDK, however I’m having trouble integrating it into my own project. The GRID SDK version is 2.3.7.
I can successfully create the NvIFR interface, passing in my D3D11Device*.
However, I cannot call NvIFRSetUpH264HWEncoder. Using the same params as the samples, NVIFR_ERROR_DX_DRIVER_FAILURE is always returned. I’ve tried changing sizes, back buffer formats, but I get the same error.
Under what conditions is NVIFR_ERROR_DX_DRIVER_FAILURE returned? Where should I start looking? Is there anyway to get some debugging info?
[xposting from devtalk, maybe I’ll get some traction here :)]
