在Ubuntu 14.10中安装OpenCV [英] Installing OpenCV in Ubuntu 14.10

问题描述

我正在根据说明. 我安装了所有提到的依赖项，但是当我尝试运行make时，出现了这样的错误:

I'm trying to install OpenCV in Ubuntu 14.10 according to instruction. I installed all mentioned dependencies, but when I'm trying to run make I get such errors:

/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，对于所有编解码器，

. 这些错误:

for all codecs, as I think. And these errors:

    In file included from /home/ilia/opencv-2.4.8/modules/highgui/src/cap_ffmpeg.cpp:45:0:

看起来找不到一些头文件，但是我安装了所有必需的dev软件包 libswscale-dev，libavdevice-dev，libavfilter-dev，libavformat-dev，libavcodec-dev.我该怎么办才能解决这些问题?

It looks like it can not find some header files, but I installed all necessary dev packages libswscale-dev, libavdevice-dev, libavfilter-dev, libavformat-dev, libavcodec-dev. What should I do to resolve these problems?

推荐答案

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

Unless you have special reasons I would suggest installing the OpenCV that are already in the Ubuntu repository: 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.

For video codecs I suggest simply trying to install all ffmpeg and gstreamer related codec packages.
