SDL2 source code analysis 8: video display summary, sdl2 source codeThis article briefly summarizes the source code of the SDL video.The structure of the SDL display video involves the following structure: SDL_Window: indicates the window SDL_Renderer: indicates the Renderer. SDL_Texture: represents the texture SDL_Rect: a rectangular box used to determine the position of the texture display. Shows th

This document records the Audio Playback Technology of SDL. The version used here is sdl2. In fact, SDL does not provide the video/audio playback function. It only encapsulates the underlying API for video/audio playback. On Windows, SDL encapsulates direct3d APIs for video playback and directsound APIs for audio playback. Because SDL is designed to simplify the development of video and audio playback, it is very easy to Use SDL to play video (YUV/RGB

This is a creation in Article, where the information may have evolved or changed. Learning Golang for a period of time, from no clue to everywhere, and then to the rest of the peace of mind to study SDL2 also have a small six months. Tonight refactoring before the study code, found that if you do not write the article, may later review this time to write the code to spend time, so this article to do a bit of code on the mark, and for Will learn Golang
