FR: standalone application

Since January, I've been using FFmpeg CLIs to mux my files before uploading to YouTube.

While I understand the usefulness of the plug-ins, especially for people using tools offering similar UX (Dolby Atmos in Pro Tools, for example), it's actually a more involved and time consuming setup to use the Eclipsa plug-ins when the task at hand is only muxing the multi-channel audio with the video file.

Personally, I don't mind using FFmpeg for muxing as it's a quite fast process (around 50x real time on my computer), but I know that using CLIs in the terminal is baffling or even repulsive to many people.

So this is essentially my plea for a simple standalone app for muxing audio and video.

Thanks!
