HEVC hardware decoding method and system

The invention relates to an HEVC (High Efficiency Video Coding) hardware decoding method and system for a Windows system. The system comprises a D3D11VA hardware decoder and a Direct3D11 hardware renderer, after the D3D11VA hardware decoder and the Direct3D11 hardware renderer are initialized, direct connection between the D3D11VA hardware decoder and the Direct3D11 hardware renderer is established, a video stream of an HEVC video is obtained, a D3D11VA equipment handle is opened, HEVC decoding configuration is found, hardware decoding is carried out on the video stream to obtain coded data, and the coded data are sent to the Direct3D11 hardware renderer. And rendering the coded data into an image by using a Direct3D11 hardware video renderer. The method and the system do not need to depend on a third-party framework, memory copying is not needed in the whole process, higher decoding efficiency and a more convenient control process can be provided, and meanwhile the CPU occupancy rate and the memory occupancy
