找不到匹配的GLX视频？SDL_GL_DOUBLEBUFFER绝对不是SDL_SetVideoMode()的有效flags参数。
1、简介Simple DirectMedia Layer, 简称SDL,是一个自由的跨平台的多媒体开发包,主要通过OpenGL和2D视频帧缓冲(framebuffer)提供对音频、键盘、鼠标、游戏操纵杆 (joystick)和3D硬件的底层访问。它被广泛的应用于MPEG回放软件、模拟器和多个著名游戏中,如获得大奖的文明:权倾天下 (Civilization: Call To Power)的...

SDL_Flip函数的作用是:在支持双缓冲(double-buffering)的硬件上,建立flip并返回。硬件将等待vertical retrace,然后在下一个视频surface blit或者执行锁定返回前交换视频缓冲区。如果硬件不支持双缓冲,那么等同于调用SDL_UpdateRect(screen, 0, 0, 0, 0),即对整个screen的绘制区域进行刷新。 void DrawScene(SDL_...
