## What it is
JavaCPP Presets provides Java bindings for commonly used native C++ libraries such as OpenCV, FFmpeg, and many others, built on the JavaCPP technology. It ships prebuilt binaries for multiple platforms including Android, iOS, Linux, macOS, and Windows via Maven Central.

## Use cases
- use opencv from java
- process video with ffmpeg in a jvm app
- call native c++ libraries from java
- build android apps with native computer vision libraries
- run deep learning inference in java
- access librealsense or hdf5 from the jvm

## When to choose
- you need mature native C++ library functionality in Java or on Android without writing JNI yourself
- you want Maven-managed, prebuilt cross-platform native binaries

## When to avoid
- you work outside the JVM ecosystem
- you need a lightweight pure-Java solution with no native dependencies

## Facets
- artifact type: library
- maturity: active
- function: sdk, image-processing, video-processing, computer-vision, machine-learning, audio-processing, graphics
- domain: cross-platform, developer-tools, computer-vision, image-processing, machine-learning, android-tools
- platform: windows, jvm, cross-platform
- tags: javacpp, native-libraries, cpp-bindings, maven, opencv, ffmpeg, java-bindings, video, linux, macos, android, ios
