• "TypeError : byte indices must be integers or slices, not str" Converting bytes to ints

  13 janvier 2017, par Lewis

  I am using a different program (ffmpeg) to grab the length of a youtube video that was downloaded in order to randomize a specific point in the video. However I am getting this error when I am trying to execute this code :

  def grabTimeOfDownloadedYoutubeVideo(youtubeVideo):
  
      process = subprocess.Popen(['/usr/local/bin/ffmpeg', '-i', youtubeVideo], stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
  
      stdout, stderr = process.communicate()
  
      matches = str(re.search(b"Duration:\s{1}(?P<hours>\d+?):(?P<minutes>\d+?):(?P<seconds>\d+\.\d+?),", stdout, re.DOTALL).groupdict()).encode()
  
      print(matches)
  
      hours = int(matches['hours'])
  
      minutes = int(matches['minutes'])
  
      seconds = int(matches['seconds'])
  
      total = 0
  
      total += 60 * 60 * hours
  
      total += 60 * minutes
  
      total += seconds
  
      print(total)
  
  </seconds></minutes></hours>

  The matches variable prints out to this :

  b"{'minutes': b'04', 'hours': b'00', 'seconds': b'24.94'}"

  So all of the output comes out with a ’b’ at the beginning of it. How do I remove the ’b’ and just get the number ?

  Full error message here :

  Traceback (most recent call last):
  
    File "bot.py", line 87, in <module>
  
      grabTimeOfDownloadedYoutubeVideo("videos/1.mp4")
  
    File "bot.py", line 77, in grabTimeOfDownloadedYoutubeVideo
  
      hours = int(matches['hours'])

• FFMPEG how do i add 1 image to 1 video

  15 avril 2020, par das

  ok I found a code online from 1 of the StackOverflow page tested it and it adds 10 seconds black screen before the video starts.
  
Summary
  
i have 55.mp4 and logo.png i want to replace black screen with png logo

  



  ffmpeg -i 55.mp4 -filter_complex "[0:v]tpad=start_duration=10:color=black[v];[0:a]adelay=10000|10000[a]" -map "[v]" -map "[a]" -y out2222.mp4


  



  I have logo.png in the same path how do I use that instead of black screen.
  
I do not wish to use overlays. I want it as it is, just replace black-screen with my png
