FFmpeg+SDL+SOUI 摄像头显示demo

SOUI真窗口显示：点击打开链接 简单修改；

注册真窗口：

//设置真窗口处理接口
CSouiRealWndHandler * pRealWndHandler = new CSouiRealWndHandler();
theApp->SetRealWndHandler(pRealWndHandler);
pRealWndHandler->Release();

SDL2.0创建窗口时：

CRect rc= ((SRealWnd *)arg)->GetWindowRect();
screen_w =rc.Width();
screen_h = rc.Height();
// screen = SDL_CreateWindow("FFmpeg Read Camera", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED,
// screen_w, screen_h,SDL_WINDOW_OPENGL|SDL_WINDOW_RESIZABLE);

//都可以
screen = SDL_CreateWindowFrom((void *)((SRealWnd *)arg)->GetRealHwnd());
//screen = SDL_CreateWindowFrom((void *)((SRealWnd *)arg)->GetData());
