操作系统：ubuntu20.04
IDE:Visual Studio Code
编程语言：C++11
架构：瑞芯微3568

环境准备

‌源码下载‌

获取OpenCV 4.2源码及contrib模块（需版本匹配），推荐从GitHub官方仓库下载。

bash 复制代码

  wget https://github.com/opencv/opencv/archive/4.2.0.tar.gz

‌安装依赖‌

安装编译工具及基础依赖库：

bash 复制代码

 sudo apt update
sudo apt install cmake git build-essential libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
sudo apt install libjpeg-dev libpng-dev libtiff-dev libopenexr-dev libv4

编译配置

写了个编译脚本：

bash 复制代码

#!/bin/bash

export LEAN=/usr/local
export PKG_CONFIG_PATH=$LEAN/ffmpeg4.2/lib/pkgconfig:$PKG_CONFIG_PATH

cd opencv-4.2.0
rm -rf build
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE \
      -D CMAKE_INSTALL_PREFIX=/usr/local/opencv420 \
      -D WITH_FFMPEG=ON \
      -D WITH_LIBV4L=ON \
      -D BUILD_EXAMPLES=OFF \
      -D BUILD_opencv_python2=OFF \
      -D BUILD_opencv_python3=OFF ..

make all -j8
make install

然后就是比编译ffmpeg更漫长的等待...

出现以下输出,安装完成：

bash 复制代码
