The new High Efficiency Video Coding Standard (HEVC) was finalized in January 2013. Compared to its predecessor H.264 / MPEG4-AVC, this new international standard is able to reduce the bitrate by 50% for the same subjective video quality. This paper investigates decoder optimizations that are needed to achieve HEVC real-time software decoding on a mobile processor. It is shown that HEVC real-time decoding up to high definition video is feasible using instruction extensions of the processor while decoding 4K ultra high definition video in real-time requires additional parallel processing. For parallel processing, a picture-level parallel approach has been chosen because it is generic and does not require bitstreams with special indication.

A GPU multi-video decoding implementation based on VDPAU is presented to solve multi-video display problem. VdpDevice and VdpDecoder is integrated, and the FFmpeg video is decoded with GPU parallel processing. The experimental results show that the CPU utilization is greatly reduced and the multi-video decoding processing scheme based on VDPAU can greatly improve the ability of video decoding.

According to the algorithm of AVS audio and video decoding standard, this paper proposes a proposal of AVS decoding based on SoC method. This method can reduce the complexity of AVS decoder effectively. Using the hardware and software co-design ideas can reduce the difficulty of designing a decoder while improving the flexibility of decoding.
