I am looking for a step by step guide to link ffmpeg with a basic hello world app.

  


• Tkinter window and script freeze when filedialog is used

  11 décembre 2020, par RandomInternetPerson

  Im developing a audio player for python. Unfortunately, it appears as if after a modification, the file dialog portion of the script ceased working. The code below is a minimum reproducible example of the offending bit.

  


  # -----------------------Setup-----------------------
# Imports
from tkinter import * 
from tkinter.ttk import * 
from tkinter import filedialog

import simpleaudio
import subprocess

# GUI
root = Tk() 
root.title("CupPlayer") 
menubar = Menu(root)
file = Menu(menubar, tearoff = 0)
root.config(menu = menubar)
# ----------------------Functions---------------------
def file_selector(): 
    filename = filedialog.askopenfilename()
    
    root.update()
    if filename.endswith('.mp3'):
            subprocess.call(['ffmpeg', '-i', filename,
                                'audio.wav'])
btn = Button(root, text = 'search file !', bd = '5', 
                          command = file_selector) 

mainloop()
