• How to run a python code via Django templates ?

  18 novembre 2018, par Iskender Berdiev

  I want to execute code below when the is submitted (project on Django) :

  from os import system, listdir, remove
  
  link = 'https://www.youtube.com/watch?v=ME9yO1KEVoo'
  
  
  
  def download(): ## Downloading a video from YouTube using youtube-dl
  
      system("youtube-dl -o download {}".format(link))
  
  
  
  def convert():  ## Converting downloaded video to mp3 format via ffmpeg.exe(same directory)
  
      listOfFiles = listdir('.')
  
      for i in listOfFiles:
  
          if i.startswith("download"):
  
              name = i
  
              system("ffmpeg -i {} download.mp3".format(name))
  
  
  
  def main():
  
      download()
  
      convert()
  
  
  
  main()

  I have tried to put this code into views.py :

  class download(TemplateView):
  
      def main(request):
  
          if request.method == 'POST':
  
              link = 'https://www.youtube.com/watch?v=ME9yO1KEVoo'
  
              system("youtube-dl -o download {}".format(link))
  
              listOfFiles = listdir('.')
  
              for i in listOfFiles:
  
                  if i.startswith("download"):
  
                      name = i
  
                      system("ffmpeg -i {} download.mp3".format(name))
  
          return redirect ('loader/wait.html')

  urls.py :

  path('wait/', views.download.as_view(), name='wait')

  and the html form which is submitted to run views.download.as_view() :

  <form action="{% url " method="POST">{% csrf_token %}
  
  <input type="submit" value="Yes" />
  
  </form>

• OSX/Cocoa app crashing when finished running ffmpeg terminal command

  23 juin 2014, par codeman

  I’m running ffmpeg within my Mac app and it’s actually creating the output file successfully. The problem is that the app crashes as soon as the ffmpeg command is finished. Any ideas on how to prevent the crash ?

  Here’s the code I’m using to run ffmpeg in my Mac app :

  char ffm_cmd[512];
  
  NSString *command = [NSString stringWithFormat:@"%@%@ \\\n-filter_complex '[0:0][1:0][2:0][3:0]concat=n=%d:v=0:a=1[out]' \\\n-map '[out]' %@/output.wav", escapedPath, concatFiles, count, self.outputFolderPath];
  
  const char *cString = [command cStringUsingEncoding:NSASCIIStringEncoding];
  
  sprintf(ffm_cmd,cString);
  
  system(ffm_cmd);
