说明：  H264中的整数DCT变换编码及量化代码,并附有原文的DCT编码、量化的说明文档。本源码从X264及JM中抽取后整整理得来，并用原文档中的示例数据进行了测试，与原文档结果完全一样，是学习H.264不可多得的参考资源. 已通过测试。
(H264 in the integer DCT transform coding and quantization code, along with the original DCT coding, quantitative documentation. The source extraction from the X264 and JM sharp finishing, and tested with sample data in the original document, exactly the same as the original document results, learning H.264 rare reference resources. Has been tested.)
