DirectX 摄像头捕获

基于qt的视频采集系统，有xvid压缩和解压-Qt-based video acquisition system, have xvid compression and decompression

实验中发现opencv的cvCaptureFromCAM 使用的是vfw,采用消息机制,速度较慢,测试发现fps只有 9-12左右,太慢了. 发现经过使用directshow后速度提升到60帧/s.在opencv group上了解到这是一个普遍问题,也许有人做过转换,却没有完整的例子与代码.在此贴出.对希望提高opencv视频分析速度的有所帮助-Opencv experiment found that the cvCaptureFromCAM using vfw, the use of information mechanism to slow fps test found that only about 9-12, too slow. Discovered through the use of DirectShow velocity to 60/s. In opencv group understanding that this is a common problem, perhaps someone has done the conversion, but no complete examples and code.此贴out in. opencv want to improve the speed of video analysis help

要显示字符，首先需要获得字模数据，我们使用字模软件PCtoLCD2002（配套光盘里有，网络上也随处可下）。该字模软件用1bit 代表一个像素点的色彩，用户可以根据需要来决定这1bit 数据（0 或1）代表的色彩。

realplay 伴侣，装了realpaly你需要装上这个，那就更有味道了。-realplay partners, installed realpaly you need to install this, it more flavor.

C++帧间差分法的代码，用于对视频的研究。这个叫人怎么描述，他就是个代码，能用就用，不能用请找别的。
