  • FFmpeg in Python File already exists error

    24 septembre 2018, par Abdul Rehman

    I’m working on a project using python(3.6) and Django(2.0) in which i’m converting a video to mp4 if it’s in any other formate.

    Here’s my code :

    from views.py :

    def generate_thumbnail(filename, thumb_name):
       print('func called')
       print(filename)
       video_input_path = os.path.join(filename)
       img_output_path = os.path.join(thumb_name)
       subprocess.call(['ffmpeg', '-i', video_input_path, '-ss', '00:00:00.000', 'vframes', '1', img_output_path])


    def convert_to_mp4(video_name, only_name):
       os.popen(
           "ffmpeg -i '{input}' -ac 2 -b:v 2000k -c:a aac -c:v libx264 -b:a 160k -vprofile high -bf 0 -strict experimental -f mp4 '{output}.mp4'".format(
               input=video_name, output=only_name))
       return True


    def perform_upload(video, thumbnail):
       print('vdieo name is: {}'.format(video))
       servise = discovery.build('storage', 'v1', credentials=credentials)
       bucket_name = 'test_bucket004'
       print('Uploading the video...')
       media = MediaFileUpload(video, chunksize=4149304, mimetype='video/mp4',
                               resumable=True)
       req = servise.objects().insert(
           bucket=bucket_name,
           name=str(video),
           media_body=media,
           body={"cacheControl": "public,max-age=31536000"},
           predefinedAcl='publicRead'
       )
       resp = None
       while resp is None:
           status, resp = req.next_chunk()
       print(resp)
       video_url = 'http://storage.googleapis.com/' + bucket_name + '/' + str(video)

       print('Uploading your thumbnail...')
       media = MediaFileUpload(thumbnail, chunksize=4149304, mimetype='image/jpeg',
                               resumable=True)
       req = servise.objects().insert(
           bucket=bucket_name,
           name=str(thumbnail),
           media_body=media,
           body={"cacheControl": "public,max-age=31536000"},
           predefinedAcl='publicRead'
       )
       resp = None
       while resp is None:
           status, resp = req.next_chunk()
       print(resp)
       thumb_url = 'https://storage.googleapis.com/' + bucket_name + '/' + str(thumbnail)

       return video_url, thumb_url


    class VideoConverter(generics.ListCreateAPIView):
       def get(self, request, *args, **kwargs):
           return HttpResponse('Get request', status=200)

       def post(self, request, *args, **kwargs):
           serializer = VideoConverterSerializer(data=self.request.data)
           validation = serializer.is_valid()
           print(serializer.errors)
           if validation is True:
               url = request.POST.get('video_url')
               filename = url.split('/')
               filename = filename[-1]
               print(filename)
               ext = filename.split('.')
               print(ext[-1])
               only_name = ext[0]
               urllib.request.urlretrieve(url, filename)
               generate_thumbnail(filename, only_name + '_thumbnail.jpg')
               if ext == 'mp4':
                   videourl, thumb_url = perform_upload(filename, only_name + '_thumbnail.jpg')
               else:
                   conversion = convert_to_mp4(filename, only_name)
                   if conversion is True:
                       videourl, thumb_url = perform_upload(only_name + '.mp4', only_name + '_thumbnail.jpg')

               return HttpResponse('Video url is: {}\n \nThumbnail url is: {}'.format(videourl, thumb_url))
           else:
               return HttpResponse('Not a valid request')

    But when I pass it a video of Mp4 format it returns an error in the IDE console like this :

    File ’PHP_GCS.mp4’ already exists. Overwrite ? [y/N]

    and stop the execution here until I press the enter button.I’m really confused why this is happining because when the video is already mp4 i’m not using ffmpeg but only for thumbnail generaton.

    What can be wrong here ?

    Thanks in advance !
