ITU-T H.264.2 (03/2005)

H.264 先进的视频编码的参考软件

本建议书为ITU-T H.264建议书 | ISO/IEC 14496-10 提供作为电子附件的参考软件。该软件是 ITU-T H.264.2建议书的组成部分。
本建议书的目的是提供下列各项。
• 参考解码器软件能力：采用ITU-T H.264建议书 | ISO/IEC 14496 10中规定的解码过程的方式，解码符合 ITU-T H.264建议书 | ISO/IEC 14496 10 的比特流。
• 参考编码器软件能力：产生符合 ITU-T H.264建议书 | ISO/IEC 14496 10的比特流。
在实现一个符合ITU-T H.264建议书 | ISO/IEC 14496 10的编码器或解码器时不需要使用这个参考软件。在 ITU-T H.264建议书 | ISO/IEC 14496 10中制定的要求优先于参考软件行动。
本版本的建议书综合了由勘误1 (2005-10)引出的修订，本勘误只影响C源码。
勘误1修正了参考解码器软件中各种较小的差错并提供了非标准化样品编码过程的增强。软件版本当前称为 "JM10.1"。
