vs2010写个程序，总是显示访问冲突，求高手解决
用vs2010与opencv写了个程序，程序中有四个for循环（没有嵌套，顺序的），这四个循环都要调用一个函数（传递的参数是指针），结果第一个for循环调用时正常运行，第二个for循环调用这个for循环时，总是显示“finalshot.exe 中的 0x01271ca4 处有未经处理的异常: 0xC0000005: 读取位置 0x00000008 时发生访问冲突”。是不是参数是指针的问题，求高手解决。谢了

是你的这4个函数没有执行成功。执行完后，41 42 43 44这4个视频文件是空的。
img1 = cvQueryFrame(capture2);
img2 = cvQueryFrame(capture3);
img3 = cvQueryFrame(capture4);
img4 = cvQueryFrame(capture1);
img0 = xuanzhuanpj(img1, img2, img3, img4);
这样img1到img4都是空指针，这样传空指针到xuanzhuanpj函数里面，当然要出错了。
但是你把这4个函数注释掉，然后你自己拷贝4个已经有内容的avi文件到F盘下，然后执行函数，就成功了。
所以你自己好好检查一下cvCreateVideoWriter函数，参数是不是给对了，或者别的什么原因。我好长一段时间没写OpenCV了，忘了具体的了。
[解决办法]
如果运行exe的机器不是开发exe的机器，请将开发机上bin\opencv_*.dll拷贝到运行机上和exe相同的目录下。
