 Summary of the bug: basically, if ffmpeg stops to prompt you
 "File 'yo.mp4' already exists. Overwrite ? [y/N]"

 If there are other (for instance ERROR) log messages, they will appear and
 obscure the prompt, causing the prompt to be basically lost in the mix:


 How to reproduce:create the file "yo.mp4" then run this:
