我正在按照说明在Ubuntu 14.10中安装OpenCV。我已经安装了所有所需的依赖项,但是当我尝试运行make
时,出现以下错误:
/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,我认为都适用。还有这些错误:

看起来找不到一些头文件,但我已经安装了所有必要的开发包,包括libswscale-dev、libavdevice-dev、libavfilter-dev、libavformat-dev和libavcodec-dev。为解决这些问题,我该怎么做?
