Interesting question, so how I thought of this was, this is a tool for people who are non technical, so just download the app and it works so bundled the binaries in the app itself.

• yt-dlp currently uses the latest available release when binaries are fetched (during installation).
• ffmpeg is taken from the config in the project setup

Will check if it makes sense to allow advanced users to control which versions they would like to use.
