摘要
视频监控系统对视频压缩率和编码实时性具有很高的要求,X264算法的高压缩率和DM642处理器的高性能正好满足这两个需求。文中分析了基于DM642的X264视频监控系统的软件实现,讨论了基于RF5的算法移植过程和移植后的程序优化,并给出了QCIF格式的实时视频编码的优化结果。
High video compression efficiency and real time encoding feature are neccessary for a video surveillance system. The high compression ratio of X264 algorithm and the excellent performance of DM642 processor meet the both requirements exactly. The paper analyzes the software implementation of X264 video surveillance system based on DM642 DSP, discusses the transplantation and optimization of X264 algorithm under RF5 framework, and finally presents the optimization result of real time video coding in QCIF format.
