ijkplayer源码分析之surface与opengl关联初始化 在step 1中进行IjkMediaPlayer实例的构造,构造过程中完成的step 2加载so并在加载过程中将底层的一些信息保存到IjkMediaPlayer实例中 step 3将IjkMediaPlayer实例对象设置到底层IjkMediaPlayer结构体中,创建底层IjkMediaPlayer结构体。在创建结构体的同时设置message_loop回调函数...
I want to load an SDL_Surface into an OpenGL texture with padding (so that NPOT->POT) and apply a color key on the surface afterwards. I either end up colorkeying all pixels, regardless of their color, or not colorkey anything at all. I have tried a lot of different things, but non...
本文整理汇总了Python中pygame.surface.Surface._from_sdl_surface方法的典型用法代码示例。如果您正苦于以下问题:Python Surface._from_sdl_surface方法的具体用法?Python Surface._from_sdl_surface怎么用?Python Surface._from_sdl_surface使用的例子?那么恭喜您, 这里精选的方法代码示例或许可以为您提供帮助。您也可以...
SDL_Texture on the other hand, is used in a hardware rendering, textures are stored in VRAM and you don't have access to it directly as with SDL_Surface. The rendering operations are accelerated by GPU, using, internally, either OpenGL or DirectX (available only on Windows) API, which in...
mainWindow = SDL_CreateWindow("Tests OpenGL", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, WINDOW_WIDTH, WINDOW_HEIGHT, SDL_WINDOW_SHOWN); SDL_Surface* window_s = SDL_GetWindowSurface(mainWindow);intscreen_bg_color = Graphic_base::Color::format32_rgb(100,100,100); ...
SDL2还为SDL表面提供了一个新的功能,叫做软拉伸,它允许你将图像按比例放大到不同的尺寸进行blit。在本教程中,我们将把一张只有屏幕一半大小的图像拉伸到全尺寸。 代码语言:javascript 复制 SDL_Surface*loadSurface(std::string path){//最终优化后的图像SDL_Surface*optimizedSurface=NULL;//在指定路径加载图像SDL...
(core_cpu.controllers.video.window, &config::win_width, &config::win_height); } //Initialize new window - OpenGL else { core_cpu.controllers.video.opengl_init(); } } //Pause emulation else if((event.type == SDL_KEYDOWN) && (event.key.keysym.sym == SDLK_PAUSE)) { config::...
If we take a look at OpenGL, what happens when we load a Surface and we render it specifying a width and height bigger than the Surface's original width and height? It gets automatically scaled (unless you specify you want to be repeated). In SDL there is no automatic way of scaling ...

使用无X窗口系统的OpenGL 、、 如何在OpenGL平台上不使用X窗口系统,可以直接将OpenGL图形发送到Framebuffer设备上吗?有一个名为DirectFB (Direct FrameBuffer)的项目。使用DirectFB,我们可以做到这一点,但是DirectFB需要为每个硬件提供驱动程序,我想使用一个只有Linux驱动程序的图形卡。 浏览2提问于2010-06-14得票数 ...
