温柔一刀

cpp调用c是要用extern如下使用ffmpeg库的接口extern "C" {#include "libavcodec/avcodec.h"#include "libavformat/avformat.h"#include "libswscale/swscale.h"#include "libavformat/avio.h"#include "libswscale/version.h"}

ffmpeg相关的数据结构SDL

效果：代码：~/code/MediaPlayer$ tree .├── main.cpp├── mediaplayer.cpp├── mediaplayer.h├── MediaPlayer.pro└── MediaPlayer.pro.userMediaPlayer.pro#-------------------------------------------------## Project created by QtCreator 2020-08-17T13:43:30#

如QT 工程那样在源代码下用命令生成工程项目那样,qmake -project name.pro下面简单写一个基于cmake的小程序:创建如下文件:build为空目录cmake + vs code可以在任何平台使用在ubuntun 18.04中使用cmake写cpp code,#include <stdio.h>int main(int argc,char** argv){ printf("cmake test\n"); return 0;}配置CMakeL.
