• cx_freeze - opens command window when running ffmpeg.exe or ffplay.exe through the GUI of the program created - how to hide this ?

  14 août 2020, par James Allnutt

  I have built an MSI using cx_freeze for my python program tool.box.

  


  Everything works great - however, I implemented this snippet in my setup.py :

  


  base = None
if (sys.platform == "win32"):
    base = "Win32GUI"


  


  to hide the cmd window that would typically open when you run the final .exe cx_freeze produces.

  


  This works fine, and now when I launch, I do not see this blank cmd window.

  


  However - in my program, I have a few buttons that call ffplay.exe and ffmpeg.exe - previously, without that snippet, I could run the program and when I clicked those buttons no CMD window would appear - now, however, it does - and it shows the output of ffplay or ffmpeg.

  


  In my main.py, I have the following commands :

  


  command_play = [ffplay_path, originalAudio, "-ss", str(actual_start_segment), "-t", "10", "-nodisp", "-autoexit"]

ffmpeg_command = FFmpeg(
            inputs={originalAudio: None},
            outputs={new_filename: ['-ss', str(actual_start_segment), '-to', str(actual_end_segment), '-async', '1', '-strict', '-2', '-ar', '44100', '-ab', '56k', '-ac', '1', '-y']}
        )


  


  Both of which are set to not display the CMD window.

  


  They only seem to do so when I compile. Any suggestions on how I can hide these so my GUI based program doesn't have CMD windows appearing when the end user utilises it's features ?

  However, if I try capturing from the screen given the size and offset of the child window, then I risk losing data when another window floats ontop of it, I switch to another tab while recording, I resize the child window, or move the child window. Instead, I'd like to use ffmpeg to capture from specifically that child window.

  Ideas ? Tips ? Maybe some other hacks to accomplish this ? Thanks :)

• ffmpeg capture single window screen freezes with only mouse working

  2 septembre 2015, par Saad Abdullah

  Scenario and Problem :
  I have two machines with windows 8.1 installed. On one computer, every thing works fine with video recording by using gdigrab to capture a window by title. But on the other pc, the desktop recording works fine, but when it comes to capture single window by title, the video freezes with only mouse working. (to be exact, if i play webcam or images in the window being captured, it records the content too, but when some video is played it starts showing black screen or freezed at first frame.

  Commandline :
  here is the commandline args

  ffmpeg -f gdigrab -framerate 30 -i title="Video - VLC media player" germ.flv

  What can be the issue on the other pc ?
