FFmpegKit is a collection of tools to use FFmpeg1 in Android, iOS, Linux, macOS, tvOS, Flutter and React Native applications.
It includes scripts to build FFmpeg native libraries, a wrapper library to run FFmpeg/FFprobe commands in
applications and 8 prebuilt binary packages available at Github,
Maven Central, CocoaPods, pub and npm.

See React Native to learn more about FFmpegKit for React Native.
Use android.sh, ios.sh, linux.sh, macos.sh and tvos.sh to build FFmpegKit for each native platform.
All scripts support additional options to enable optional libraries and disable platform architectures. See Building wiki page for the details.
FFmpegKit is a wrapper library that allows you to easily run FFmpeg/FFprobe commands in applications. It
provides additional features on top of FFmpeg to enable platform specific resources, control how commands are
executed and how the results are handled.
Android library of FFmpegKit has a Java API, Apple libraries (iOS, macOS, tvOS) have an Objective-C
API, Flutter library comes with a Dart API, Linux library has a C++ API and React Native library provides
a JavaScript API with Typescript definitions, which are identical in terms of features and capabilities.
There are eight different ffmpeg-kit packages distributed on
Github,
Maven Central, CocoaPods, pub and
npm.
Below you can see which system libraries and external libraries are enabled in each one of them.
Please remember that some parts of FFmpeg are licensed under the GPL and only GPL licensed ffmpeg-kit packages
include them.

FFmpegKit binaries are published in two release variants: Main Release and LTS Release.
Main releases include complete functionality of the library and support the latest SDK/API features.
LTS releases are customized to support a wider range of devices. They are built using older API/SDK versions, so some features are not available on them.
This table shows the differences between two variants.

A more detailed documentation is available under Wiki.
You can see how FFmpegKit is used inside an application by running test applications created under
FFmpegKit Test project.
All applications are identical and supports command execution, video encoding, accessing https urls, encoding audio, burning subtitles, video stabilisation, pipe operations and concurrent command execution.
FFmpegKit library alone is licensed under the LGPL v3.0.
FFmpegKit bundles (.aar archives, frameworks, xcframeworks), which include both FFmpegKit and FFmpeg
libraries, are also licensed under the LGPL v3.0. However, if the source code is built using the optional
--enable-gpl flag or prebuilt binaries with -gpl postfix are used, then FFmpegKit bundles become subject to the
GPL v3.0. Because, FFmpeg is licensed under the GPL v3.0 in those bundles. And that makes the whole bundle
effectively subject to the GPL v3.0.
FFmpegKit build scripts always configure FFmpeg with --enable-version3 option. And never enable non-free
libraries. Thus, FFmpeg libraries created by FFmpegKit are licensed under the LGPL v3.0 by default. Only when
--enable-gpl is provided they become subject to GPL v3.0. That is how prebuilt binaries with -gpl postfix are
compiled.
Refer to Licenses to see the licenses of all libraries.
Trademark lists the trademarks used in the FFmpegKit
documentation.
It is not clearly explained in their documentation, but it is believed that FFmpeg, kvazaar, x264 and x265
include algorithms which are subject to software patents. If you live in a country where software algorithms are
patentable then you'll probably need to pay royalty fees to patent holders. We are not lawyers though, so we recommend
that you seek legal advice first. See FFmpeg Patent Mini-FAQ.
openh264 clearly states that it uses patented algorithms. Therefore, if you build ffmpeg-kit with openh264 and
distribute that library, then you are subject to pay MPEG LA licensing fees. Refer to
OpenH264 FAQ page for the details.
