DirectX Video Acceleration 2.0
DirectX Video Acceleration (DXVA) is an API and a corresponding DDI for using hardware-acceleration to speed up video codec processing. Software codecs and software video processors can use DXVA to offload certain CPU-intensive operations to the GPU. For example, a software decoder can offload the inverse discrete cosine transform (iDCT) to the GPU.
