DXVA Checker Finds If Your CPU Or GPU Supports DirectX Video Acceleration
With the advent of high definition video content, it became quite difficult for the CPUs to encode HD videos while at the same time perform other user tasks. DXVA (DirectX Video Acceleration) by Microsoft, made this job a tad easier on the CPU side, by offloading certain CPU-intensive tasks such as iDCT, motion compensation and video deinterlacing, to the GPU. The GPU is not only a more efficient component to handle such load, but also performs better in terms of the video rendering and color reproduction. For this reason, companies like AMD and Nvidia have incorporated DXVA to their own video decoding technologies (AMD’s UVD and Nvidia’s Pure Video), used in their computer graphics card series. DXVA by default, can be used if you’re watching a video on Blu-ray etc., but now, a wide array of media players, including Media Player Classic and KMplayer support DXVA, so that you can use your graphics card to enjoy your favorite HD movies in different video container formats, for instance MKV. If you want to check whether your graphics card supports DXVA or not, then give DXVA Checker a try. It’s a small tool, designed to conduct some GPU tests to check support for DXVA. Details after the jump.
