ffmpeg整合sdl2显示一个可以手动关闭的播放器窗口

主要代码如下：

#include<stdio.h>
#include "libavutil/avutil.h"
#include "libavutil/timestamp.h"
#include "libavdevice/avdevice.h"
#include "libavformat/avformat.h"
#include "libavcodec/avcodec.h"
#include "libswscale/swscale.h"
#include "ff.h"
#include "SDL2/SDL.h"



void sdl(void) {

    int quit=1;

    SDL_Event event;

        SDL_Window *window=NULL;

        SDL_Renderer *render=NULL;

        SDL_Init(SDL_INIT_VIDEO|SDL_INIT_AUDIO);

        window=SDL_CreateWindow("SDL2 Window",200,200,640,480,SDL_WINDOW_SHOWN);

        if(!window){
            printf("Faild to Create window!");
            goto __EXIT;
        }
        render= SDL_CreateRenderer(window,-1,0);

        if(!render){

            SDL_Log("Faild to create render!");
            goto __DWINDOW;
        }
           SDL_SetRenderDrawColor(render,255,0,0,255);
        SDL_RenderClear(render);
        SDL_RenderPresent(render);

        //SDL_Delay(3000);

        do{
            SDL_WaitEvent(&event);
            switch(event.type){
                case SDL_QUIT:
                    quit=0;
                break;
                default:
                    SDL_Log("event type is %d\n",event.type);
            }

        }while(quit);

        __DWINDOW:
            SDL_DestroyWindow(window);

        __EXIT:
            SDL_Quit();

      return ;
}
