  Adds code for corner detection and ransac

  This code is to start experiments with global motion models.

  The corner detection can be either fast_9 or Harris.
  Corner matching is currently based on normalized correlation.
  Three flavors of ransac are used to estimate either a
  homography (8-param), or an affine model (6-param) or a
  rotation-zoom only affine model (4-param).

  The highest level API for the library is in vp9_global_motion.h,
  where there are two functions - one for computing a single model
  and another for computing multiple models up to a maximum number
  provided or until a desired inlier probability is achieved.

• Transcode video using celery and ffmpeg in django

  28 octobre 2015, par Robin

  I would like to transcode user uploaded videos using celery. I think first I should upload the video, and spawn a celery task for transcoding.

  Maybe something like this in the tasks.py :

  subprocess.call('ffmpeg -i path/.../original path/.../output')

  Just completed First steps with celery, so confused how to do so in the views.py and tasks.py. Also is it a good solution ? I would really appreciate your help and advice. Thank you.

  models.py :

  class Video(models.Model):
  
      user = models.ForeignKey(User)
  
      title = models.CharField(max_length=100)
  
      original = models.FileField(upload_to=get_upload_file_name)
  
      mp4_480 = models.FileField(upload_to=get_upload_file_name, blank=True, null=True)
  
      mp4_720 = models.FileField(upload_to=get_upload_file_name, blank=True, null=True)
  
      privacy = models.CharField(max_length=1,choices=PRIVACY, default='F')
  
      pub_date = models.DateTimeField(auto_now_add=True, auto_now=False)

  my incomplete views.py :

  @login_required
  
  def upload_video(request):
  
      if request.method == 'POST':
  
          form = VideoForm(request.POST, request.FILES)
  
          if form.is_valid():
  
              if form.cleaned_data:
  
                  user = request.user
  
                  #
  
                  #
  
                  # No IDEA WHAT TO DO NEXT
  
                  #
  
                  #
  
                  return HttpResponseRedirect('/')
  
  
  
      else:
  
          form = VideoForm()
  
          return render(request, 'upload_video.html', {
  
              'form':form
  
              })
