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, `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. ### 9. Packages There are eight different `ffmpeg-kit` packages distributed on [Github](https://github.com/arthenica/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. <table> <thead> <tr> <th align="center"></th> <th align="center">min</th> <th align="center">min-gpl</th> <th align="center">https</th> <th align="center">https-gpl</th> <th align="center">audio</th> <th align="center">video</th> <th align="center">full</th> <th align="center">full-gpl</th> </tr> </thead> <tbody> <tr> <td align="center">external libraries</td> <td align="center">-</td> <td align="center">vid.stab x264 x265 xvidcore</td> <td align="center">gmp gnutls</td> <td align="center">gmp gnutls vid.stab x264 x265 xvidcore</td> <td align="center">lame libilbc libvorbis opencore-amr opus shine soxr speex twolame vo-amrwbenc</td> <td align="center">dav1d fontconfig freetype fribidi kvazaar libass libiconv libtheora libvpx libwebp snappy zimg</td> <td align="center">dav1d fontconfig freetype fribidi gmp gnutls kvazaar lame libass libiconv libilbc libtheora libvorbis libvpx libwebp libxml2 opencore-amr opus shine snappy soxr speex twolame vo-amrwbenc zimg</td> <td align="center">dav1d fontconfig freetype fribidi gmp gnutls kvazaar lame libass libiconv libilbc libtheora libvorbis libvpx libwebp libxml2 opencore-amr opus shine snappy soxr speex twolame vid.stab vo-amrwbenc x264 x265 xvidcore zimg</td> </tr> <tr> <td align="center">android system libraries</td> <td align="center" colspan=8>zlib MediaCodec</td> </tr> <tr> <td align="center">ios system libraries</td> <td align="center" colspan=8>bzip2 AudioToolbox AVFoundation iconv VideoToolbox zlib</td> </tr> <tr> <tr> <td align="center">macos system libraries</td> <td align="center" colspan=8>bzip2 AudioToolbox AVFoundation Core Image iconv OpenCL OpenGL VideoToolbox zlib</td> </tr> <tr> <td align="center">tvos system libraries</td> <td align="center" colspan=8>bzip2 AudioToolbox iconv VideoToolbox zlib</td> </tr> </tbody> </table> - `AVFoundation` is not available on `tvOS` - `VideoToolbox` is not available on LTS releases of `iOS` and `tvOS` - `zimg` is supported since `v4.5.1` ### 10. Versions `FFmpegKit` binaries generated use the same major and minor version numbers as the upstream `FFmpeg` project. The third and last number in the version string, if exists, is specific to `FFmpegKit`. It shows different releases from the same `FFmpeg` release branch. `dev` part in the version string indicates that `FFmpeg` source code is cloned from the `FFmpeg` `master` branch and the exact version number of `FFmpeg` is obtained using the `git describe --tags` command. | Platforms | FFmpegKit Version | FFmpeg Version | Release Date | |:----------------:|:---------------------------------------------------------------------------------:|:--------------:|:------------:| | Flutter | [6.0.3](https://github.com/arthenica/ffmpeg-kit/releases/tag/flutter.v6.0.3) | 6.0 | Sep 19, 2023 | | React Native | [6.0.2](https://github.com/arthenica/ffmpeg-kit/releases/tag/react.native.v6.0.2) | 6.0 | Sep 19, 2023 | | Flutter | [6.0.2](https://github.com/arthenica/ffmpeg-kit/releases/tag/flutter.v6.0.2) | 6.0 | Sep 03, 2023 | | React Native | [6.0.1](https://github.com/arthenica/ffmpeg-kit/releases/tag/react.native.v6.0.1) | 6.0 | Sep 03, 2023 | | Flutter | [6.0.1](https://github.com/arthenica/ffmpeg-kit/releases/tag/flutter.v6.0.1) | 6.0 | Sep 03, 2023 | | React Native | [6.0.0](https://github.com/arthenica/ffmpeg-kit/releases/tag/react.native.v6.0.0) | 6.0 | Aug 27, 2023 | | Flutter | [6.0.0](https://github.com/arthenica/ffmpeg-kit/releases/tag/flutter.v6.0.0) | 6.0 | Aug 27, 2023 | | Android Apple | [6.0](https://github.com/arthenica/ffmpeg-kit/releases/tag/v6.0) | 6.0 | Aug 21, 2023 | | React Native | [5.1.0](https://github.com/arthenica/ffmpeg-kit/releases/tag/react.native.v5.1.0) | 5.1.2 | Oct 02, 2022 | | Flutter | [5.1.0](https://github.com/arthenica/ffmpeg-kit/releases/tag/flutter.v5.1.0) | 5.1.2 | Oct 02, 2022 | | Android Apple | [5.1](https://github.com/arthenica/ffmpeg-kit/releases/tag/v5.1) | 5.1.2 | Sep 29, 2022 | | React Native | [4.5.2](https://github.com/arthenica/ffmpeg-kit/releases/tag/react.native.v4.5.2) | 4.5-dev-3393 | May 25, 2022 | | Flutter | [4.5.1](https://github.com/arthenica/ffmpeg-kit/releases/tag/flutter.v4.5.1) | 4.5-dev-3393 | Jan 02, 2022 | | React Native | [4.5.1](https://github.com/arthenica/ffmpeg-kit/releases/tag/react.native.v4.5.1) | 4.5-dev-3393 | Jan 02, 2022 | | Android | [4.5.1](https://github.com/arthenica/ffmpeg-kit/releases/tag/v4.5.1) | 4.5-dev-3393 | Jan 01, 2022 | | Apple | [4.5.1](https://github.com/arthenica/ffmpeg-kit/releases/tag/v4.5.1) | 4.5-dev-3393 | Dec 30, 2021 | | Flutter | [4.5.0](https://github.com/arthenica/ffmpeg-kit/releases/tag/flutter.v4.5.0) | 4.5-dev-2008 | Oct 05, 2021 | | React Native | [4.5.0](https://github.com/arthenica/ffmpeg-kit/releases/tag/react.native.v4.5.0) | 4.5-dev-2008 | Oct 01, 2021 | | Android Apple | [4.5](https://github.com/arthenica/ffmpeg-kit/releases/tag/v4.5) | 4.5-dev-2008 | Sep 18, 2021 | | Android Apple | [4.4](https://github.com/arthenica/ffmpeg-kit/releases/tag/v4.4) | 4.4-dev-3015 | Mar 03, 2021 | ### 11. 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 arm64-v8a x86 x86-64 | arm-v7a arm-v7a-neon arm64-v8a x86 x86-64 | | iOS Min SDK | 12.1 | 10 | | iOS VideoToolbox | Yes | - | | iOS AVFoundation | Yes | - | | iOS Architectures | arm64 arm64-simulator arm64-mac-catalyst x86-64 x86-64-mac-catalyst | armv7 arm64 i386 x86-64 | | iOS Bundle Format | XCFrameworks | Frameworks | | Mac Catalyst Min Version | 14.0 | - | | macOS Min SDK | 10.15 | 10.12 | | macOS AVFoundation | Yes | - | | macOS Architectures | arm64 x86-64 | x86-64 | | macOS Bundle Format | XCFrameworks | Frameworks | | tvOS Min SDK | 11.0 | 10.0 | | tvOS VideoToolbox | Yes | - | | tvOS Architectures | arm64 x86-64 arm64-simulator | arm64 x86-64 | | tvOS Bundle Format | XCFrameworks | Frameworks | ### 12. Documentation A more detailed documentation is available under [Wiki](https://github.com/arthenica/ffmpeg-kit/wiki). ### 13. Test Applications You can see how `FFmpegKit` is used inside an application by running test applications created under [FFmpegKit Test](https://github.com/arthenica/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. ### 14. License `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](https://github.com/arthenica/ffmpeg-kit/wiki/Licenses) to see the licenses of all libraries. [Trademark](https://github.com/arthenica/ffmpeg-kit/wiki/Trademark) lists the trademarks used in the `FFmpegKit` documentation. ### 15. 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. ### 16. Trademarks 1 `FFmpeg` is a trademark of [Fabrice Bellard](http://www.bellard.org/). `FFmpegKit` is an independent project and not affiliated with the `FFmpeg` trademark holder. ### 17.
