• expected str, bytes or os.PathLike object, not NoneType for subprocess of ffmpeg

  15 janvier 2024, par ejmin ejoni

  I dont know much about ffmpeg, subprocess and its functions, im trying to take a screenshot form a video and save it at my other field of my model.
this is my model :

  


  class SubSong(models.Model):
song = models.ForeignKey(SongPage, on_delete=models.CASCADE, related_name='related_song')
create = jmodels.jDateField(auto_now_add=True)
user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='related_user')
video = models.FileField(upload_to='sub_video/',)
like = models.ManyToManyField(User, blank=True, )
total_like = models.PositiveIntegerField(default=0)
is_allowed = models.BooleanField(default=False)
image_sub = ThumbImage(upload_to='sub_songs/', default='1.jpg')

def __str__(self):
    return self.song.title


  


  and views.py

  


      if request.method == 'POST':
    authen(request)
    form = MyTryForm(request.POST, request.FILES)
    if form.is_valid():
        data = form.cleaned_data
        x = SubSong.objects.create(song_id=id,
                                   user_id=request.user.id,
                                   video=data['video'], )
        path = x.video.name
        out = path.replace('sub_video/', '').replace('mp4', 'jpg')
        z=subprocess.check_output(
            ffmpeg.input('media/' + path, ss='00:00:50').filter(
                'thumbnail').output('media/sub_songs/' + out, vframes=1).run(), text=True)
        x.image_sub=z
        x.save()
        messages.success(request, 'ویدیوی شما با موفقیت ارسال شد ، پس از بررسی منتشر خواهد شد')
        return redirect(request.META.get('HTTP_REFERER'))

    else:
        messages.error(request, 'ویدیوی شما بارگداری نشد')
        return redirect(request.META.get('HTTP_REFERER'))


  


  it can save the video and also default picture 1.jpg at image_sub. also it can save scrrenshot at the media/sub_song/.but my problem is that it gives me error :
expected str, bytes or os.PathLike object, not NoneType
how i should return the screen from subprocess to save it as my image_sub field ? and why do this error raise ? i dont want to see this error again
