1.下载sdl2，ffmpeg dev

2.qt的配置

win32: LIBS += -L$$PWD/libffmpeg/lib/ -lavcodec -lavdevice -lavfilter -lavformat -lavutil -lpostproc -lswscale
win32: LIBS += -L$$PWD/libSDL/lib/x86/ -lSDL2 -lSDL2main

INCLUDEPATH += $$PWD/libffmpeg/include
DEPENDPATH += $$PWD/libffmpeg/include

INCLUDEPATH += $$PWD/libSDL/include
DEPENDPATH += $$PWD/libSDL/include

3.类接口源码（参考了雷博士的源码）

#ifndef VIDEOPLAYER_H
#define VIDEOPLAYER_H

#ifdef _WIN32
//Windows
extern "C"
{
#include "libavcodec/avcodec.h"
#include "libavformat/avformat.h"
#include "libswscale/swscale.h"
#include "SDL.h"
};
#else
//Linux...
#ifdef __cplusplus
extern "C"
{
#endif
#include <libavcodec/avcodec.h>
#include <libavformat/avformat.h>
#include <libswscale/swscale.h>
#include <SDL2/SDL.h>
#ifdef __cplusplus
};
#endif
#endif
