  dnn : convert tf.pad to native model in python script, and load/execute it in the c code.
  since tf.pad is enabled, the conv2d(valid) changes back to its original behavior.

• dnn : change .model file format to put layer number at the end of file

  dnn : change .model file format to put layer number at the end of file
  currently, the layer number is at the beginning of the .model file,
  
  so we have to scan twice in python script, the first scan to get the
  
  layer number. Only one scan needed after put the layer number at the
  
  end of .model file.

• Celery to process task and modify the model fields

  15 juillet 2015, par Robin

  I would like to convert video into mp4 using ffmpeg and celery for the asynchronous task. When user uploads a video, it will be for the original_video and save it. After that I want celery to convert it into a different version for the mp4_720 field. However I am confused on how to apply that logic using celery.

  app.models.py :

  class Video(models.Model):
  
      title = models.CharField(max_length=75)
  
      pubdate = models.DateTimeField(default=timezone.now)
  
      original_video = models.FileField(upload_to=get_upload_file_name)
  
      mp4_720 = models.FileField(upload_to=get_upload_file_name, blank=True, null=True)
  
      converted = models.BooleanField(default=False)

  app.views.py :

  def upload_video(request):
  
      if request.POST:
  
          form = VideoForm(request.POST, request.FILES)
  
          if form.is_valid():
  
              video = form.save(commit=False)
  
              video.save()
  
  
  
              // Celery to convert the video
  
              convert_video.delay(video)
  
  
  
              return HttpResponseRedirect('/')
  
      else:
  
          form = VideoForm()
  
      return render(request, 'upload_video.html', {
  
          'form':form
  
      })

  app.tasks.py :

  @app.task
  
  def convert_video(video):
  
  
  
      // Convert the original video into required format and save it in the mp4_720 field using the following command:
  
      //subprocess.call('ffmpeg -i (path of the original_video) (video for mp4_720)')
  
  
  
      // Change the converted boolean field to True
  
  
  
      // Save

  Basically my question is how to save the converted video in mp4_720. Your help and guidance will be very much appreciated. Thank you.

  ** update **

  What I want that method to do is first convert the video.original_video and then save the converted video in the video.mp4_720 field. If all has been done correctly, change the video.converted to True. How do I define the method to do so ?
