Windows下VScode配置FFmpeg开发环境保姆级教程

相关准备

1. 提前在本地开发环境中配置好mingw64或者msys2开发工具集。
   
   

2. 安装VScode软件。
   

下载Windows版本的FFmpeg相关库

1. 下载地址：https://ffmpeg.org/download.html

2. 下载步骤：如下图。
   
   
   

3. 下载后的文件：包含了可执行文件ffmpeg、ffplay、ffprobe，头文件、库文件等。

   ├─bin
   ├─doc
   ├─include
   │  ├─libavcodec
   │  ├─libavdevice
   │  ├─libavfilter
   │  ├─libavformat
   │  ├─libavutil
   │  ├─libswresample
   │  └─libswscale
   └─lib└─pkgconfig
   

VScode配置FFmpeg步骤

1. 创建文件夹test-ffmpeg

   mkdir test-ffmpeg
   

2. 将ffmpeg库文件移到test-ffmpeg文件夹

   mv ffmpeg test-ffmpeg
   

3. VScode打开test-ffmpeg文件夹
   

4. 配置 c_cpp_properties.json

   • 按住“ctrl+shift+p”，选择 C/C++:Edit Configurations（JSON），点开默认内容如下：
     
     

   • 配置c_cpp_properties.json内容，修改如下：
     

     {"configurations": [{"name": "Win32","includePath": ["${workspaceFolder}/**","C:/Users/yance/downloads/test-ffmpeg/ffmpeg/include"],"defines": ["_DEBUG","UNICODE","_UNICODE"],"windowsSdkVersion": "10.0.26100.0","compilerPath": "C:/mingw64/bin/gcc.exe","cStandard": "c17","cppStandard": "c++17","intelliSenseMode": "windows-gcc-x64"}],"version": 4
     }
     

5. 配置 tasks.json

   • 按住“ctrl+shift+p”，输入“tasks”，选择第一个，即默认的task。
     

   • 配置tasks.json，修改内容如下：
     

     {"version": "2.0.0","tasks": [{"type": "cppbuild","label": "C/C++: gcc.exe 生成ffmpeg活动文件","command": "C:/mingw64/bin/gcc.exe","args": ["-fdiagnostics-color=always","-g","${file}","-L","C:/Users/yance/downloads/test-ffmpeg/ffmpeg/lib","-I","C:/Users/yance/downloads/test-ffmpeg/ffmpeg/include","-lavcodec","-lavdevice","-lavfilter","-lavformat","-lavutil","-lswresample","-lswscale","-o","${fileDirname}\\${fileBasenameNoExtension}.exe"],"options": {"cwd": "${fileDirname}"},"problemMatcher": ["$gcc"],"group": {"kind": "build","isDefault": true},"detail": "编译器: C:/mingw64/bin/gcc.exe"}]
     }
     

6. 配置 launch.json

   • 点击VScode顶部的“运行”
     

   • 点击“添加配置”，在弹出的窗口上选择“C++(GDB/LLDB)”
     

   • 配置launch.json，修改内容如下：
     

     {// 使用 IntelliSense 了解相关属性。 // 悬停以查看现有属性的描述。// 欲了解更多信息，请访问: https://go.microsoft.com/fwlink/?linkid=830387"version": "0.2.0","configurations": [{"name": "(gdb) 启动","type": "cppdbg","request": "launch","program": "${fileDirname}\\${fileBasenameNoExtension}.exe","args": [],"stopAtEntry": false,"cwd": "${fileDirname}","environment": [],"externalConsole": false,"MIMode": "gdb","miDebuggerPath": "c:/mingw64/bin/gdb.exe","setupCommands": [{"description": "为 gdb 启用整齐打印","text": "-enable-pretty-printing","ignoreFailures": true},{"description": "将反汇编风格设置为 Intel","text": "-gdb-set disassembly-flavor intel","ignoreFailures": true}]}]
     }
     

7. 创建main.c文件进行测试

   • 编辑测试代码

   #include <stdio.h>
   #include <stdlib.h>
   #include <string.h>
   #include <stdint.h>
   #include <libavutil/log.h>int main()
   {av_log_set_level(AV_LOG_DEBUG);printf("hello FFmpeg!\n");av_log(NULL, AV_LOG_INFO, "hello FFmpeg!\n");return 0;
   }
   

   • 运行
   • 生成exe文件并输出结果
     

备注

• 可以根据需求将gcc的编译器修改成g++；
• 可以根据需求再配置OpenCV等库文件，过程都类似。
