• FFprobe Check Stream Link

  16 juillet 2015, par Krasic

  I am trying to use FFprobe to test if a streaming link is active or not.

  For example this is a working streaming link :

  ffprobe -loglevel quiet -show_streams rtmp://Lrmh0w.cloud.influxis.com/yoy/_definst_/185

  I do get output which mean link is active.

  However, once I change link to something not work :

  ffprobe -loglevel quiet -show_streams rtmp://Lrmh0w.cloud.influxis.com/yoy/_definst_/18555555555

  The command keeps running in background with no result.

  Is there a way to bypass this, or is there any ffprobe timeout parameter ?
  I couldn’t find it from the official website documentation.

• 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 ?
