I'm making a python script to convert video or image to ASCII art and I need ffmpeg for the last part. The thing is that when I build EXE file using PyInstaller (and select -noconsole option), when code execution comes to the point when ffmpeg is needed, console window still opens for each ffmpeg process opened. I open two processes, code for which is provided here:

process_in = ffmpeg.input(open_path, r=fps)[v_stream_indx].output('pipe:', format='rawvideo', pix_fmt='rgb24', r=fps).run_async(pipe_stdout=True, cmd=ffmpeg_path)

process_out = ffmpeg.input('pipe:', format='rawvideo', pix_fmt='rgb24', s=f'{width}x{height}', r=fps).output(ffmpeg.input(open_path, r=fps, vn=None), save_path, pix_fmt=pixel_format, r=fps, vcodec=og_codec, codec="copy").overwrite_output().run_async(pipe_stdin=True, cmd=ffmpeg_path)

Of course I don't want those console windows as my app has GUI. Strangely, there is no output in any of those 2 windows (I would expect it to be because there are many logs printed out when run from pycharm where main script output is printed out, BTW is there a way to disable that?).
