错误中的函数' cedarx_cache_op，mem_cpy 在哪？

这两个函数都是在库文件中，编译出错应该是你的库文件没有链接好

gcc version 4.6.1 (Sourcery CodeBench Lite 2011.09-70)
这个可以用，目前正在捣鼓中.... ...

哥们，能付把你的4.6.1版本编译器提供下，我找不到啊，这几天了，还是编译器版本问题啊，Q:376226323,跪谢！

这个例子中，V4L2在设置参数中，设置帧的宽和高貌似是自动获取的（在set_para函数中），而我这获取的是176*144，画面好小啊，我尝试过将那两个改为640*480（我的摄像头支持这么大的），但是修改之后画面是一跳一跳的，一点不连续，176*144的还能流畅显示，不知道这是什么原因啊？        format.fmt.pix.width = width;  format.fmt.pix.height =height;我记得V4L2这个参数是可以自己设定的啊

终于实现摄像头采集->h264硬编->h264硬解->实时LCD显示了，感谢共享该库！

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 ...

请问你之怎样解决这问题的啊？

将摄像头抓的数据保存为yuv文件，放在YUV viewer中播放是很流畅的。改了下楼主的这个文件，去掉了显示那部 ...

请问怎么将 将摄像头抓的数据保存为yuv文件？？
