摘 要: | JM8.6是JVT为学习与测试 H .264视频算法而开发的官方编解码模型。理解经典测试模型JM8.6的程序结构是算法研究和实际应用的基础。通过RDO方式下代价函数的代码跟踪分析,对JM 8.6核心编码函数的结构进行了具体研究,得出了H .264的关键函数encode-one-macroblock()在JM8.6测试模型中的帧内与帧间最优模式的选择流程图和RDCost-for-macroblocks()函数自上而下调用子函数的总体模式框图。

Abstract: | JM8 .6 is the official module of encoding and decoding for the test and research of H .264 video algorithm by JV T .T he research on the algorithm and the real application are based on the understanding of the program structure of the classic test module JM 8 .6 .By the tracking analysis of the cost function code in the RDO mode ,the structure of JM 8 .6 core encoding function has been cleared up .Besides ,the flow diagram of the key function (encode_one_macroblock) in the best module of the intra -frame and inter -frame as well as the general pattern framework of the key function (RDCost_for_macroblocks) is given . |
