Abstract

In this paper, we first discussed the video decoding standard and its architecture, and then analyzed the decoding complexity of each process. By using the benefit of the CUDA programming model, and taking advantages of GPU to optimize the decoding process of MC (motion compensation) and CSC(color space conversion) that are very time consuming, we proposed a MC accelerating method based on CUDA, and a CSC accelerating method based on CUDA and OpenGL shader. The experiments show that it is feasible to decode high definition video in real time using GPGPU-CUDA.
