• How to get a online video's duration without downloading the full video ?

  8 février 2017, par David Zhuang

  To get a video’s duration and resolution, I’ve got this function :

  def getvideosize(url, verbose=False):
  
  try:
  
      if url.startswith('http:') or url.startswith('https:'):
  
          ffprobe_command = ['ffprobe', '-icy', '0', '-loglevel', 'repeat+warning' if verbose else 'repeat+error', '-print_format', 'json', '-select_streams', 'v', '-show_streams', '-timeout', '60000000', '-user-agent', BILIGRAB_UA, url]
  
      else:
  
          ffprobe_command = ['ffprobe', '-loglevel', 'repeat+warning' if verbose else 'repeat+error', '-print_format', 'json', '-select_streams', 'v', '-show_streams', url]
  
      logcommand(ffprobe_command)
  
      ffprobe_process = subprocess.Popen(ffprobe_command, stdout=subprocess.PIPE)
  
      try:
  
          ffprobe_output = json.loads(ffprobe_process.communicate()[0].decode('utf-8', 'replace'))
  
      except KeyboardInterrupt:
  
          logging.warning('Cancelling getting video size, press Ctrl-C again to terminate.')
  
          ffprobe_process.terminate()
  
          return 0, 0
  
      width, height, widthxheight, duration = 0, 0, 0, 0
  
      for stream in dict.get(ffprobe_output, 'streams') or []:
  
          if dict.get(stream, 'duration') > duration:
  
              duration = dict.get(stream, 'duration')
  
          if dict.get(stream, 'width')*dict.get(stream, 'height') > widthxheight:
  
              width, height = dict.get(stream, 'width'), dict.get(stream, 'height')
  
      if duration == 0:
  
          duration = 1800
  
      return [[int(width), int(height)], int(float(duration))+1]
  
  except Exception as e:
  
      logorraise(e)
  
      return [[0, 0], 0]

  But some online videos comes without duration tag. Can we do something to get its duration ?

• Downloading a video with full capacity of my PC with FFMPEG [closed]

  25 juin 2020, par akamai

  I'm trying to download a M3U8 video with FFmpeg.
  
ffmpeg -i "www.example.com/video.mp4" -c copy -bsf:a aac_adtstoasc output.mp4

  


  FFmpeg downloads very slowly compared to a direct download. I'm on a 1 Gigabit network and it take around 1 hour to download the entire video.

  


  I read the documentation and they mentioned about CPU Flag
But I don't know if that will solve my problem.
