Abstract

High Efficiency Video Coding (HEVC) standard achieves double compression efficiency compared to H.264/AVC with the adoption of more flexible coding structure and advanced coding tools. On the other hand, the coding mode space is too large and it’s very time consuming. With the development of many-core computing architecture, parallelizing HEVC encoding on such platforms is an efficient approach to fulfill the high computational requirement. In this paper, we propose a highly parallel MPI method which is based on the reference software for the HEVC. Firstly we split the video into multiple computing cores, and then the video frame is compressed simultaneously. Experimental results show that our proposed parallel MPI method gets an overall speed up of more than 10x with 336 computing cores, compared with the non-parallel baseline.
