I'm not sure how the pipeline works, I'll take your word for it.
But in my own testing, if I use Dxva or Dx11, the render time is always slightly higher than if I use CPU decode.
This was especially true on my iGPU and slower graphics cards.
On my HD3000 for example it will stall out /drop frames if I use Dxva decode, whereas if i let it Cpu decode, and gpu render, it will play smoothly.
