MystiQ is a FFmpeg GUI, cross-platform for Windows and Linux, and Open source.
I think it deserves a thread in this forum.

I tested in Ubuntu 20.04 and it works fine, the project seems a fork of QWinFF.

https://github.com/qwinff/qwinff

The project seems abandoned since 3 years ago, sadly the main developer Maikel Llamaret passed away 2 years ago.

But the source code is publicly available to everyone who want to improve and continue the development. It's developed in C++ and Qt5
