请问怎么将 将摄像头抓的数据保存为yuv文件？？

直接在保存一帧的那个函数里以写文件的方式保存啊

楼主你好！ client我编译OK了，但执行的时候打开摄像头有问题：
StartStreaming: Unable to start captur ...

我也遇到这个问题，不过我是CB1，求楼主解答～

这个可以在A10/A20上使用，但是A20上会有一些小小的问题，不过不影响使用

main 函数增加初始化
g_pCedarV = CedarvEncInit(mVideoWidth,mVideoHeight,1024*1024,GetFrmBufCB);
InitCapture();

摄像头ov7670，采用ashwing的   queryvideo () 查询可知摄像头是支持nv12的。
