• Python PyQT : How to call a GUI function from a worker thread ?

  18 juillet 2014, par rainer

  I have a pyqt gui and calling a long process (ffmpeg) which I put on a separate thread to not block the gui. I then want to update a progress bar when one command of a longer list of commands finishes. The problem is, that I can’t call a function in the gui thread out of the worker thread. So I let run a ticker in the worker thread, but when I update the progress bar with a while loop and reading the ticker value, the gui gets blocked again. How can I solve this. I used currently python threading and not Qthread.
  Thx for any help !

  import threading, pexpect
  
  
  
  self.cmd_list = ['ffmpeg -i file outfile','and so on']
  
  
  
  self.stop_proc = False
  
  self.executeCMD()
  
  
  
  def spawn_ffmpeg_cmd(self):
  
      for cmd in self.cmd_list:
  
          if self.stop_proc == False:
  
              thread = pexpect.spawn(cmd)
  
              print "\nstarted: %s" % cmd
  
              cpl = thread.compile_pattern_list([pexpect.EOF,"frame= *\d+ fps=*\d+",'(.+)'])
  
  
  
              while True:
  
                  i = thread.expect_list(cpl, timeout=None)
  
                  if i == 0: # EOF
  
                      print "the sub process exited"
  
                      self.pgticker += 1
  
                      break
  
                  elif i == 1:
  
                      frame_number_fps = thread.match.group(0)
  
                      print frame_number_fps
  
                      thread.close
  
                  elif i == 2:
  
                      pass
  
      self.startButton.setEnabled(True)
  
  
  
  
  
  def executeCMD(self):
  
      self.startButton.setEnabled(False)
  
      self.pgticker = 0
  
      threading.Thread(target=self.spawn_ffmpeg_cmd, name="_proc").start()
  
  
  
  
  
  def stopprocess(self):
  
      self.stop_proc = True
  
      self.cmd_list = []
  
      os.system('pkill ffmpeg') 
  
      self.pgticker = len(self.cmd_list)
  
      self.startButton.setEnabled(True)
  
  
  
  
  
  def updateProgress(self):  
  
      pgfactor = 100 / len(self.cmd_list)
  
      progress = 0.0
  
      progress = pgfactor*int(self.pgticker)
  
      self.progressBar.setProperty("value", progress)

• List Directory of files to text file sorted by creation date but don't show creation creation date in file

  25 mars 2019, par Oli Shingfield

  I’ve been doing some research on this problem but I can’t get my head around it to suit my particular issue.

  I would like to create a text file of a list of files in a directory, sorted by date but I don’t want the date to be shown in the file.
  The code I have so far is :

  #create list of clips to merge
  
  save_path = 'downloads/'
  
  ignored = 'test.bat','mergeclips.bat','draw.bat'
  
  onlyfiles = [f for f in listdir('downloads/') if isfile(join('downloads/', f)) if f not in ignored]
  
  
  
  with open('downloads/clipstomerge.txt', 'w') as f:
  
      for item in onlyfiles:
  
          f.write("file '%s'\n" % item )

  This code ignores the bat files but lists everything else out to a text file in a format ready for ffmpeg to merge the clips. The format of the text file looks like this :

  file 'ARandomClipName.mov'
  
  file 'Butterflies.mov'
  
  file 'Chickens.mov'

  At the moment the files are sorted alphabetically but I would like it to be sorted by creation date.
  Does anyone have any ideas how I could modify my code to fix my problem ?
