- Ubuntu 20.04 搭建 CLion FFmpeg 開發環境_TYYJ-洪偉的博客-CSDN博客
安裝CLion
- 首先到 jetbrains 官網 https://www.jetbrains.com/clion/ 下載 CLion 安裝包 CLion-2021.1.tar.gz
- 使用finalshell和ubuntu之間配置ssh鏈接
- 將Clion-2022.1.tar.gz 使用move移動到 /home/chy-cpabe路徑下
- 使用命令 tar -xvzf?Clion-2022.1.tar.gz 進行解壓
- cd clion-2022.1
- cd bin
- sudo ./clion.sh 啟動clion
- 激活
- 創建項目 選擇/home/chy-cpabe/CLionProjects/learn_ffmpeg這個路徑，即項目的名字叫做learn_ffmpeg
二、運行使用 FFmpeg lib 的 Demo
- 音視頻處理 ffmpeg下載、編譯和安裝_MY CUP OF TEA的博客-CSDN博客
- 參考上面鏈接 創建環境?ffmpeg_build?ffmpeg_source 等
- 編譯好的 FFmpeg 庫位于 ffmpeg_build 目錄下
cmake
- 與參考鏈接相比
- 刪除了 uuid 和?vdpau
- 配置文件中的引入庫順序也至關重要，如果庫引入順序顛倒，可能導致編譯無法通過。要注意編譯依賴先后順序
