  avfilter/palettegen : base box split decision on a perceptual model
  Similar to the change in paletteuse, we rely on a perceptual model to
  
  decide how and where to split the box.

  Detected path traversal attempt in '/home/mrlonely/Desktop/lumen/lumen/media/thumbnail/6.jpeg'

  


  


  When i run this in the views.py :

  


  def generate_thumbnail(instance):
   post = Post.objects.get(pk=instance.pk)
   output = 'media/thumbnail/' + post.title + '.jpeg'
   filename_thumbnail = Path.joinpath(filename, output)  
   try:
      (
            ffmpeg
            .input(str(filename)+post.video.url, ss='00:00:20')
            .output(output, vframes=1)
            .overwrite_output()
            .run(capture_stdout=True, capture_stderr=True)
        )
      with open(filename_thumbnail, 'rb') as file_handler:
         django_file = File(file_handler)
         post.thumbnail.save(filename_thumbnail, 'thumbnail/')
   except ffmpeg.Error as e:
        print(e.stderr.decode(), file=sys.stderr)
        sys.exit(1)


  


  I am trying to connect the ffmpeg generated thumbnail to the model ImageField on the Post model (instance is post)
