我正在尝试根据
instruction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make时,我遇到了这样的错误：

/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') }

对于所有编解码器,我认为.
而这些错误：

看起来它找不到一些头文件,但我安装了所有必需的开发包
libswscale-dev,libavdevice-dev,libavfilter-dev,libavformat-dev,libavcodec-dev.我该怎么做才能解决这些问题？

除非你有特殊原因,否则我建议安装已经在Ubuntu存储库中的OpenCV：sudo apt-get install libopencv-dev

对于视频编解码器,我建议只是尝试安装所有ffmpeg和gstreamer相关的编解码器包.
