音视频处理 Clion搭建ffmpeg开发环境

Ubuntu 20.04 搭建 CLion FFmpeg 开发环境_TYYJ-洪伟的博客-CSDN博客

安装CLion

首先到 jetbrains 官网 https://www.jetbrains.com/clion/ 下载 CLion 安装包 CLion-2021.1.tar.gz
使用finalshell和ubuntu之间配置ssh链接
将Clion-2022.1.tar.gz 使用move移动到 /home/chy-cpabe路径下
使用命令 tar -xvzf Clion-2022.1.tar.gz 进行解压
cd clion-2022.1
cd bin
sudo ./clion.sh 启动clion
激活
创建项目选择/home/chy-cpabe/CLionProjects/learn_ffmpeg这个路径，即项目的名字叫做learn_ffmpeg

二、运行使用 FFmpeg lib 的 Demo

音视频处理 ffmpeg下载、编译和安装_MY CUP OF TEA的博客-CSDN博客
参考上面链接创建环境 ffmpeg_build ffmpeg_source 等
编译好的 FFmpeg 库位于 ffmpeg_build 目录下

cmake

与参考链接相比
删除了 uuid 和 vdpau
配置文件中的引入库顺序也至关重要，如果库引入顺序颠倒，可能导致编译无法通过。要注意编译依赖先后顺序
