# FFmpegKit ![GitHub release](https://img.shields.io/badge/release-v4.5-blue.svg) ![Maven Central](https://img.shields.io/maven-central/v/com.arthenica/ffmpeg-kit-min) ![CocoaPods](https://img.shields.io/cocoapods/v/ffmpeg-kit-ios-min) ![pub](https://img.shields.io/pub/v/ffmpeg_kit_flutter.svg) ![npm](https://img.shields.io/npm/v/ffmpeg-kit-react-native.svg) `FFmpegKit` is a collection of tools to use `FFmpeg` in `Android`, `iOS`, `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](https://github.com/tanersener/ffmpeg-kit/releases), [Maven Central](https://search.maven.org), [CocoaPods](https://cocoapods.org), [pub](https://pub.dev) and [npm](https://www.npmjs.com). ### 1. Features - Scripts to build FFmpeg native libraries - `FFmpegKit` wrapper library to run `FFmpeg`/`FFprobe` commands in applications - Supports native platforms: Android, iOS, macOS and tvOS - Supports hybrid platforms: Flutter, React Native - Based on FFmpeg `v4.5-dev` with optional system and external libraries - 8 prebuilt binary packages available at [Github](https://github.com/tanersener/ffmpeg-kit/releases), [Maven Central](https://search.maven.org), [CocoaPods](https://cocoapods.org), [pub](https://pub.dev) and [npm](https://www.npmjs.com) - Licensed under `LGPL 3.0`, or `GPL v3.0` if GPL licensed libraries are enabled ### 2. Android See [Android](android) to learn more about `FFmpegKit` for `Android`. ### 3. iOS, macOS, tvOS See [Apple](apple) to use `FFmpegKit` on `Apple` platforms (`iOS`, `macOS`, `tvOS`). ### 4. Flutter See [Flutter](flutter/flutter) to learn more about `FFmpegKit` for `Flutter`. ### 5. React Native See [React Native](react-native) to learn more about `FFmpegKit` for `React Native`. ### 6. Build Scripts Use `android.sh`, `ios.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](https://github.com/tanersener/ffmpeg-kit/wiki/Building) wiki page for the details. ### 7. FFmpegKit Library `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 and `React Native` library provides a `JavaScript` API, which are identical in terms of features and capabilities. ### 8. Packages There are eight different `ffmpeg-kit` packages distributed on [Github](https://github.com/tanersener/ffmpeg-kit/releases), [Maven Central](https://search.maven.org), [CocoaPods](https://cocoapods.org), [pub](https://pub.dev) and [npm](https://www.npmjs.com). 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.

- `AVFoundation` is not available on `tvOS` - `VideoToolbox` is not available on LTS releases of `iOS` and `tvOS` ### 9. Versions `FFmpegKit` binaries generated use the same major and minor version numbers as the upstream `FFmpeg` project. The exact version number of `FFmpeg` is obtained using `git describe --tags`. `dev` part in the version string indicates that `FFmpeg` source code is cloned from the `FFmpeg` `master` branch. | Platforms | FFmpegKit Version | FFmpeg Version | Release Date | | :----: | :----: | :----: | :----: | | Flutter | [4.5.0](https://github.com/tanersener/ffmpeg-kit/releases/tag/flutter.v4.5.0) | 4.5-dev-2008 | Oct 05, 2021 | | Flutter | [4.5.0-LTS](https://github.com/tanersener/ffmpeg-kit/releases/tag/flutter.v4.5.0.LTS) | 4.5-dev-2008 | Oct 05, 2021 | | React Native | [4.5.0](https://github.com/tanersener/ffmpeg-kit/releases/tag/react.native.v4.5.0) | 4.5-dev-2008 | Oct 01, 2021 | | Android

LTS Releases `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. | | Main Release | LTS Release | | :----: | :----: | :----: | | Android API Level | 24 | 16 | | Android Camera Access | Yes | - | | Android Architectures | arm-v7a-neon

Test Applications You can see how `FFmpegKit` is used inside an application by running test applications created under [FFmpegKit Test](https://github.com/tanersener/ffmpeg-kit-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. ### 13. License `FFmpegKit` is licensed under the `LGPL v3.0`. However, if source code is built using the optional `--enable-gpl` flag or prebuilt binaries with `-gpl` postfix are used, then `FFmpegKit` is subject to the `GPL v3.0` license. ### 14. Patents 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](https://ffmpeg.org/legal.html). `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](https://www.openh264.org/faq.html) page for the details. ### 15. Contributing Feel free to submit issues or pull requests. Please note that `main` includes only the latest released source code. Changes planned for the next release are developed under the `development` branches (`development` for native platforms, `development-react-native` for `react-native`, `development-flutter` for `flutter`). Therefore, if you want to create a pull request, please open it against them. ### 16.
