摘要
提出一种基于Mirror Driver的自适应屏幕录制算法MDAC,该算法运用Mirror Driver技术检测屏幕显示内容的变化,并通过检测该区域的更新频率,自适应地选择图像编码算法。实验结果表明,该算法能够在保证屏幕录像质量的情况下,大幅度降低CPU占用率和录制文件的大小。
This paper proposes an adaptive screen capturing algorithm MDAC.MDAC takes the advantage of mirror driver to capture the changes of the screen,and chooses image coding algorithm adaptively according to the update frequency of the changed area.Experimental result shows that MDAC can reduce the CPU burden and file size greatly while maintaining high image quality.
