## What it is
Allegro 5 is a cross-platform C library for video game and multimedia programming, handling windows, input, graphics, audio, fonts, and video playback. It is explicitly not a game engine, leaving program structure to the developer.

## Use cases
- write a 2d game in c
- cross-platform game programming library
- play sounds and draw bitmaps with opengl
- handle keyboard mouse and joystick input
- load fonts and render text in a game
- video playback in a native application

## When to choose
- you want a lightweight C API without engine-imposed architecture
- you need cross-platform desktop and mobile support from one codebase
- you prefer low-level control over a full game engine

## When to avoid
- you want a full-featured game engine with editor and asset pipeline
- you need high-level 3D scene management or modern engine features
- you prefer a managed language runtime like Unity or Godot

## Facets
- artifact type: library
- maturity: stable
- function: graphics, audio-processing, image-processing, video-processing, game-engine, gui
- domain: graphics, cross-platform, media
- platform: windows, cpp, c
- tags: allegro, multimedia, opengl, direct3d, input-handling, shaders, game-programming, c-api, game-development, linux, macos, android, ios
