• ffmpeg not working if run from py2app

  28 juin 2018, par dprogramz

  I’m trying to build a simple app that concats 2 mp4 files. It works fine if I run it from the command line, but if I run it from py2app app it doesn’t work. If I run the app from within the py2app in the console (eg ’dist/addTag.app/Contents/MacOS/addTag’), it works fine. It only doesn’t work if i run the app by double clicking on it. Any ideas ? code below

  #! /usr/bin/python
  
  import argparse
  
  import ffmpeg
  
  import os
  
  import shutil
  
  import sys
  
  from Tkinter import *
  
  import time
  
  
  
  fields = 'Input Video', 'Tag Video', 'Output Name'
  
  
  
  def fetch(entries, bu, lb, rt):
  
      bu['state'] = 'disabled'
  
      lb['text'] = 'working'
  
      rt.update()
  
      ffmpeg.concat(ffmpeg.input(entries[0][1].get()), ffmpeg.input(entries[1][1].get())).output(os.path.expanduser("~/desktop/")+entries[2][1].get()).run()
  
      bu['state'] = 'normal'
  
      lb['text'] = 'Ready'
  
      rt.update()
  
  
  
  
  
  def makeform(root, fields):
  
     entries = []
  
     for field in fields:
  
        row = Frame(root)
  
        lab = Label(row, width=15, text=field, anchor='w')
  
        ent = Entry(row)
  
        row.pack(side=TOP, fill=X, padx=5, pady=5)
  
        lab.pack(side=LEFT)
  
        ent.pack(side=RIGHT, expand=YES, fill=X)
  
        entries.append((field, ent))
  
     return entries
  
  
  
  if __name__ == '__main__':
  
     root = Tk()
  
     root.title("Video Maker")
  
     ents = makeform(root, fields)
  
     root.bind('<return>', (lambda event, e=ents: fetch(e))) 
  
     label = Label(root, text="Ready")
  
     label.pack(side=LEFT)  
  
     b1 = Button(root, text='Make Video',
  
            command=(lambda e=ents: fetch(e, b1, label, root)))
  
     b1.pack(side=LEFT, padx=5, pady=5)
  
     b2 = Button(root, text='Quit', command=root.quit)
