我正在尝试根据说明在Ubuntu 14.10中安装OpenCV 。我安装了所有提到的依赖项，但是当我尝试运行时make会遇到这样的错误：

/home/ilia/opencv-2.4.8/modules/highgui/src/ffmpeg_codecs.hpp:114:7: error: ‘CODEC_ID_H261’ was not declared in this scope
 { CODEC_ID_H261, MKTAG('H', '2', '6', '1') }

我认为，所有编解码器都适用。这些错误：

    In file included from /home/ilia/opencv-2.4.8/modules/highgui/src/cap_ffmpeg.cpp:45:0:
/home/ilia/opencv-2.4.8/modules/highgui/src/cap_ffmpeg_impl.hpp: In member function ‘double CvCapture_FFMPEG::getProperty(int)’:

         return av_q2d(video_st->r_frame_rate);
                                 ^

                                                                        ^

看起来找不到某些头文件，但是我安装了所有必需的开发包libswscale-dev，libavdevice-dev，libavfilter-dev，libavformat-dev，libavcodec-dev。我应该怎么做才能解决这些问题？

除非您有特殊原因，否则我建议您安装Ubuntu存储库中已经存在的OpenCV： sudo apt-get install libopencv-dev

对于视频编解码器，我建议您仅尝试安装所有与ffmpeg和gstreamer相关的编解码器软件包。
