• 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("")

• Stream Live IP cam to Youtube on FFMPEG

  24 juillet 2018, par Håkon Berntsen

  I`m streaming 2 IP cams (live webcam for tourists) from 2 Raspberry Pi, using FFMPEG (version 3.4.2) to YouTube. IPcam no.1 and Raspberry no.1 fails once a month or so, and that issue is solved with a Cron job that restarts the scripts if the service is not running.

  The stream from IPcam no.2 fail after 1 hour to maybe 24 hours, even though its the same FFMPEG command and same setup.
  FFMPEG keep streaming and the service is running on the Raspberry. YouTube stop receiving the stream, but there is no logs to be found at YouTube.

  The bandwidth is not an issue (fiber), and the cameras are both connect with Cat5 cable. The only way to restart the stream (so YouTube restart the stream) is to restart the service (since its an cronjob that restart the service only if the service is no longer running, I`m forced to do a pkill). I have also tried to set up another cron job that kills the service every 15 minutes, but its not really an elegant solution.

  Both cameras streams H264.

  Stream no.2 can be seen here : https://www.youtube.com/embed/live_stream?channel=UCEJJjA5IsjE0JjuiqfxZFaw

  The command I`m using is :

  COMMAND="sudo ffmpeg  -f lavfi -i anullsrc -thread_queue_size 512   -rtsp_transport tcp  -i ${RTSP_URL}  -vcodec libx264   -pix_fmt + -c:v copy -c:a aac  -f flv ${YOUTUBE_URL}/${YOUTUBE_KEY}"

  I hope there is someone that can help with ideas to the command or to why the stream fail.
