• Raspberry pi live stream to youtube stopped working

  27 décembre 2023, par Gergely Maros

  I have a working setup for streaming a video to youtube with my raspberry pi 3.
It was work until yesterday. Nothing changed but I have an error when I try to start the stream.
Running the following command :

  



  raspivid -o - -t 0 -w 1280 -h 720 -p -hf -fps 25 -b 2560000 | avconv -re -ar 44100 -ac 2 -acodec pcm_s16le -f s16le -ac 2 -i /dev/zero -f h264 -i - -vcodec copy -acodec aac -ab 128k -g 50 -strict experimental -f flv rtmp://a.rtmp.youtube.com/live2/my_key


  



  And get this error :

  It worked more over a month, but now (I don't know why) stopped working.

  



  Can anyone help me ?

• Python PyQt5 and youtube-dl GUI console popping when converting to mp3 with ffmpeg [on hold]

  29 juin 2018, par Giblin

  I will be jumping right to the issue I am having for a while.
  I have built a GUI software with Python 3.6 with PyQt5 and the youtube-dl package for downloading audios.
  The software downloads files in mp4, 3gp, m4a and webm extensions with no problems at all and then, here comes the mp3 to change the balance for ever !
  So what it basically does, is that while it downloads it as mp3, by the time it converts it with ffmpeg (same issue with ffprobe), a console window pops right out of the GUI and does its magic.
  I have made all the necessary customizations in the code, such as to run the ffmpeg with verbose etc but it won’t go away.
  Changing the file extension from .py to .pyw doesn’t help either.
  I think it is more of a windows problem and not really a programming issue, so I thought maybe a bat script could always run it silent in the background when it pops ? And if so, I would appreciate a heads-up because I have no experience in bat scripting.
  Thanks in advance and sorry if I went on for too long.

  EDIT :

  Here’s the console I get during the convert when I download a URL as mp3 (this pops like that until it finishes the conversion to mp3 and then disappears) :

  FFMPEG Console

  And here’s the function with the options responsible for that (for other extensions, the code is similar with just few name changes but ffmpeg isn’t necessary for them in order to convert) :

  def youtubeMP3(self):
  
      options = {
  
          'format': 'bestaudio/best',
  
          'extractaudio': True,
  
          'audioformat': 'mp3',
  
          'outtmpl': self.location + '/%(title)s-%(id)s.%(ext)s',
  
          'quiet': True,
  
          'no_warnings': True,
  
          'nocheckcertificate': True,
  
          'progress_hooks': [self.hookMP3],
  
          'postprocessors': [{
  
              'key': 'FFmpegExtractAudio',
  
              'preferredcodec': 'mp3',
  
              'preferredquality': '192'
  
          }]
  
      }
  
      value = self.urlText.text()
  
      if value != "" and validators.url(value):
  
          with youtube_dl.YoutubeDL(options) as ydl:
  
              try:
  
                  ydl.download([value])
  
                  self.progressLabel.setText("The download was successful.")
  
                  self.urlText.clear()
  
                  time.sleep(5)
  
                  self.progressLabel.setText("")
  
              except:
  
                  self.progressLabel.setText("This video URL does not exist.")
  
                  self.urlText.clear()
  
                  time.sleep(5)
  
                  self.progressLabel.setText("")
