LanguageProject Introduction
Summary
Simple Directmedia Layer (SDL) is a popular open-source library written in C, providing a simple API to access hardware functionalities like graphics, audio, and input across Windows, macOS, Linux, iOS, Android, and other platforms.
Problem Solved
Developing multimedia applications or games that run natively on multiple operating systems often requires writing platform-specific code for graphics, audio, and input. SDL provides a single API abstraction layer, significantly simplifying cross-platform development.
Core Features
Graphics Rendering Support
Provides a unified API for accessing graphics hardware across different operating systems using backends like OpenGL, Vulkan, Direct3D, etc.
Audio Playback and Recording
Offers low-level access to audio devices for sound playback and recording, supporting various formats and mixing capabilities.
Input Device Handling
Handles input from keyboard, mouse, joysticks, and game controllers with a consistent event model.
