摘要

介绍了MPEG-4编解码器在标准个人计算机上的性能分析。本文首先描述了MPEG-4的计算负荷，讨论了相关工作，然后概述了性能分析。实验结果表明，虽然解码器程序可以很容易地实时执行，但编码器需要以秒/帧的顺序执行，这需要进行大量优化以满足实时约束。

Performance analysis of MPEG-4 decoder and encoder

A performance analysis of MPEG-4 encoder and decoder programs on a standard personal computer is presented. The paper first describes the MPEG-4 computational load and discusses related works, then outlines the performance analysis. Experimental results show that while the decoder program can be easily executed in real time, the encoder requires execution times in the order of seconds per frame which call for substantial optimisation to satisfy real-time constraints.
