# FFmpegKit
FFmpeg Kit for applications.
### 1. Features
- Scripts to build FFmpeg libraries
- `FFmpegKit` wrapper library to run `FFmpeg`/`FFprobe` commands in applications
- Supports Android, iOS, macOS and tvOS
- Based on FFmpeg `v4.4-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) and [CocoaPods](https://cocoapods.org).
- Licensed under `LGPL 3.0`, or `GPL v3.0` if GPL licensed libraries are enabled
### 2. Android
See [Android](https://github.com/tanersener/ffmpeg-kit/tree/development/android) to learn more about `FFmpegKit` for
`Android`.
### 3. iOS, macOS, tvOS
See [Apple](https://github.com/tanersener/ffmpeg-kit/tree/development/apple) to use `FFmpegKit` on `Apple` platforms
(`iOS`, `macOS`, `tvOS`).
### 4. Build Scripts
Use `android.sh`, `ios.sh`, `macos.sh` and `tvos.sh` to build `FFmpegKit` for each platform.
All scripts support additional options to enable optional libraries and disable platform architectures.
### 5. 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 has a `Java` API and `Apple` libraries (`iOS`, `macOS`, `tvOS`) have an `Objective-C` API,
which are identical in terms of features and capabilities.
### 6. Binary Packages
There are eight different `ffmpeg-kit` packages distributed on
[Github](https://github.com/tanersener/ffmpeg-kit/releases),
[Maven Central](https://search.maven.org) and [CocoaPods](https://cocoapods.org).
Below you can see which 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.

### 7. Versions
`FFmpegKit` binaries generated use the same major and minor version numbers as the upstream `FFmpeg` project. The exact
version number is obtained using `git describe --tags`. `dev` part in `FFmpeg` version number indicates that `FFmpeg`
source is cloned from the `FFmpeg` `master` branch.
| FFmpegKit Version | FFmpeg Version | Release Date |
| :----: | :----: |:----: |
| [4.4](https://github.com/tanersener/ffmpeg-kit/releases/tag/v4.4) | 4.4-dev-3015 | Mar 03, 2021 |
| [4.4.LTS](https://github.com/tanersener/ffmpeg-kit/releases/tag/v4.4.LTS) | 4.4-dev-3015 | Mar 03, 2021 |
### 8. 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.

### 9. 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, concurrent command execution.
### 10. 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.
### 11. 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.
### 12. 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` branch. Therefore, if you want to create a pull request, please open it against
the `development`.
