Real-time CPU based H.265/HEVC encoding solution with x86 platform technology

摘要

The new video coding standard: High Efficiency Video Coding (HEVC)/H265 developed by ISO-IEC/MPEG and ITU-T/VCEG, has a goal to improve compression performance over the current H264/MPEG-4 standard, in the range of 50% bit-rate reduction for equal perceptual video quality. However the complexity of the algorithm and data structure of H265 is much higher than H264, that means H265 based codec will require more computing resource/power than its predecessor. In this paper we investigate the HEVC codec characters, focus on CPU based software video trans-coding technologies that provides the best video quality and most flexible programming model, maximize x86 platform capabilities at one HEVC codec, to achieve real-time performance for HEVC encoding codec on x86 platform.
