AR win32 SDK 2
好难啊,今天搞了一天,还是没成功控制信号和传感器信号都没问题,关键就是视频信号,关键是win平台下h264的现成代码太少了,目前的问题剩两个1.

lib文件我加进去了,不知道怎么还是报链接错误
在下目前成功的读取视频信号的方法只有先用nc.exe把5555端口的数据存到文件,然后用ffmpeg.exe转成opencv可以打开的格式,但是如果这样帧率就低得太离谱了
可能现在的办法只有把linux下面的代码读一段改一段慢慢来了
2. linux下面的结构体的__attribute__ ((packed))在vs2008里面怎么写,改编译选项的话整个工程都一起变,我不太希望这样,这个现在是不是问题还不知道,只是觉得我简单地把它删掉来实现编译通过可能不太靠谱 字节对齐在windows下面？ rom
你有什么好办法吗
