基于比特流修改的H.264解码器错误自动定位

摘要

A simple and useful method for fault localization for H.264 Decoder Under Test(DUT)is presented. The Bitstream that led to an error is modified to locate the faulty module without analyzing the source code. A useful tool is developed that can be used to speed up the debugging process. High efficiency of the proposed method is demonstrated in the experiments.%针对H.264解码器的测试问题，提出了一种简单实用的自动错误定位方法。对导致错误的比特流进行修改，在不进行源代码分析的情况下就达到错误定位的目的；开发了一个错误定位工具，利用这个工具可以加快调试过程。实验结果表明，此方法有良好的效率。
