[Feature] Run FFMPEG without a terminal windows opening up

[Plastermaster]

Current Situation

Currently, with FFMPEG added in the settings for the conversion, it's opening a new window for a split second after each download. This results in the window focus to be disturbed as now the terminal (I assume CMD here) is taking over the window focus, but it's not always returning the focus to the previously focused window, interrupting use of the computer, especially during larger downloads of full playlists.

Suggestion / Feature Request

If possible, it would be convenient if the use of FFMPEG didn't cause a visible window to show up at all and simply run in the background.

Looking around I've found this possible solution, but I don't know how much this might disrupt the current structure of the program. kkroening/ffmpeg-python#686 (comment)

I do not use Windows, though it's hard for me to debug this. But the proposed solution is rather high maintenance. I do not feel comfortable with overwriting external library code. This means, I need to track every change of the library. Maybe there is a simpler solution.

Does not seem to have fixed it. Still pops up for me.

I think this method might work better, running it in subprocess without windows:

The used library ffmpeg-python needs to be changed as suggested here: https://stackoverflow.com/a/74931189

Maybe you can raise an issue regarding that over there at the ffmpeg-python repo or you could try to follow up this one kkroening/ffmpeg-python#805
