I have created a Spin-off of FFmpegKit that’s fully open source with ability to deploy custom builds of FFmpegKit.
<ul>
<li>Supports 100+ external FFmpeg libraries</li>
<li>Android, Linux and Windows support</li>
<li>Full concurrency and parallel execution support</li>
<li>FFmpeg, FFprobe and FFplay support (though FFplay is currently non function on Android)</li>
<li>Callback support</li>
</ul>
Project is fully open source including native code. I’ve done a major overhaul of the API and added pure C API so the library binaries can technically be used by any language using FFI.
I am currently publishing a total of 22 different pre-built binaries for all three platforms for Audio, Video, Video+HW, Full (100+ external libraries), and Base (bare bones FFmpeg) bundles for both GPL and LGPL license compatibility.
I plan on adding support for iOS and MacOS soon.
I hope it helps developers utilize the full potential of FFmpegKit.

A Flutter plugin spin-off of FFmpegKit has been released as fully open source, supporting custom FFmpeg builds with 100+ external libraries. It targets Android, Linux, and Windows, with iOS and macOS support planned. The project ships 22 pre-built binaries covering Audio, Video, Video+HW, Full, and Base bundles under both GPL and LGPL licenses. A major API overhaul introduced a pure C API enabling use from any language via FFI, with full concurrency, parallel execution, and FFmpeg/FFprobe/FFplay support.
