Description of your issue, suggested solution and other information

While trying to develop a GUI application for youtube-dl, I encountered an annoying problem. When ffmpeg is needed for converting to MP3, it pops up one or multiple console windows. This is not acceptable for my GUI application, so I would kindly ask you if there is any possibility to hide those.

Why is this out of scope? The python module calls ffmpeg, doesn't it? Couldn't it provide some flag to ffmpeg?

Do anyone know how to fix this?
