ffmpeg.wasm and Possible license problem

The license of ffmpeg.wasm is MIT license, while ffmpeg.wasm is based on FFmpeg that it is licensed under [LGPL version 2.0](https://www.ffmpeg.org/legal.html), based on my understanding, your project is considered a derivative work that is based on FFmpeg and it must be licensed under a same license (LGPL). How have you licensed it under MIT?
