• How do I make ffmpeg not open a window when used in Python (Discord Bot Youtube Audio Player Pytube)

  20 juin 2019, par Brandalf

  I am using pytube to create a Discord bot that gets audio from a YouTube video and plays it in the voice channel using the code below. The code works perfectly fine and does what I want which is playing audio from YouTube with a link. The issue is that it uses ffmpeg and when it does, it opens the ffmpeg.exe window. Having a window constantly pop up on my screen is kind of annoying but what’s worse is that if I am playing a game in full screen, when ffmpeg is run, it will tab out of my game. So I’m wondering if there is a way to prevent ffmpeg from opening the window or if there is an alternative to playing youtube audio in Discord with a bot that doesn’t use ffmpeg.

  user=ctx.message.author
  
  voice_channel=user.voice.voice_channel
  
  vc = await client.join_voice_channel(voice_channel)
  
  player = await vc.create_ytdl_player(videoLink)
  
  video = pafy.new(videoLink) #runs ffmpeg
  
  player.start()

• ffmpeg created video receiving error message on Youtube

  1er février 2023, par David Ruan

  I am using this command to generate a video with a cover page and an audio.

  


  ffmpeg -loop 1 -r 1 -i c :/temp/coverImage.jpeg -i C :/temp/out/input.mp3 -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2" -c:a copy -shortest -c:v libx264 C :/temp/VideoOut/output.mp4

  


  But the generated video got an error message from Youtube after it is uploaded.

  


  "Your video has an unsupported aspect ratio"

  


  Any idea how to solve this issue ?

  


• PiCamera stream to youtube with ffmpeg and capture image every second

  9 octobre 2020, par MisterGray

  I'm sending a livestream with a Python script on a Raspberry Pi 4 to Youtube with ffmpeg.

  


  Additionally I want to check the stream for movements. Therefore I want to compare two frames with each other. Since this is relatively computationally intensive, I wanted to limit myself to "only" compare single frames every second.

  


  The camera.capture() command, however, seems to take very long, so the stream hangs again and again.

  


  What is the best way to get a raw frame during the stream ?

  


  Is there a better alternative to detect movements while creating a stream with ffmpeg ?

avg = None
stream_pipe = subprocess.Popen(stream_cmd, shell=True, stdin=subprocess.PIPE)

    rawCapture = PiRGBArray(camera, size = resolution)

    camera.start_recording(stream_pipe.stdin, format='h264', bitrate = 6000000)
    while True:
        camera.wait_recording(1)

        # this command takes a long time to finish
        frame = camera.capture(stream_pipe.stdin, 'rgb')
