我的系统是Ubuntu 11.10。
我一直在遵循这个指南： http://www.ozbotz.org/opencv-installation/
我还修复了一些错误（因为我安装了最新的ffmpeg 0.10.2）： http://code.opencv.org/issues/1605
然而，当我尝试做一个make时，我得到3个错误都是基于我从上面的问题链接做的修复。特别是：
cap_ffmpeg_impl.hpp:1485:32: error: ‘av_format_write_header’ was not declared in this scope
cap_ffmpeg_impl.hpp:524:64: error: too many arguments to function ‘int avformat_open_input(AVFormatContext**, const char*, AVInputFormat*, AVDictionary**)’
cap_ffmpeg_impl.hpp:486:53: error: too many arguments to function ‘int avformat_open_input(AVFormatContext**, const char*, AVInputFormat*, AVDictionary**)’
这是我的cmake：

答案 0 :(得分：1)
您的 FFMPEG版本太近无法使用OpenCV。显然，一些功能签名发生了变化，这就是破坏构建的原因。
我过去使用FFMPEG 0.5.x和0.6.x编译OpenCV，所以我建议你降级你的FFMPEG。
