  23 novembre 2019, par Ayoub Ocarina

  i got an error whene passing argements through .bat file to .exe file that converted by Pyinstaller
  my python script have the following libraries :

  import time
  
  from contextlib import closing
  
  from PIL import Image
  
  import subprocess
  
  from audiotsm import phasevocoder
  
  from audiotsm.io.wav import WavReader, WavWriter
  
  from scipy.io import wavfile
  
  import numpy as np
  
  import re
  
  import math
  
  from shutil import copyfile, rmtree
  
  import os
  
  import argparse
  
  from pytube import YouTube
  
  import cv2
  
  from datetime import datetime
  
  import datetime
  
  import os.path
  
  import shutil
  
  import webbrowser

  and this is my .bat file content :

  mode con: cols=100 lines=40
  
  @echo off
  
  COLOR 0A
  
  title VideoCuts 
  
  :LOOP
  
  if "%~1"=="" goto :END
  
  ShortCut.exe --input_file "%~1" --silent_threshold 0.1 --silent_speed 9999999.00 --frame_margin 5 --sample_rate 48000 --frame_quality 1 --output_file "%~n1_%date:~-10,2%%date:~-7,2%%date:~-4,4%_%time:~0,2%%time:~3,2%%time:~6,2%_videocuts.mp4"
  
  pause

  i also tested with this .bat file :

  ShortCut.exe --input_file="%~1" --silent_threshold=0.1 --silent_speed=9999999.00 --frame_margin=5 --sample_rate=48000 --frame_quality=1 --output_file="videocuts.mp4"

  this is my error message images during processing

• No such file error using pydub on OSX with pycharm

  15 juillet 2020, par Michael Harrison

  My ultimate aim is to run the code snippet below on Lambda but as I was having difficulties, I tried running it on my mac. I get the same error running with python2.7 on OSX as I do when I run it on AWS lambda.

  


  The code is :

  


  from pydub import AudioSegment
import os

def test():
    print("Starting")

    files = [f for f in os.listdir('.') if os.path.isfile(f)]
    for f in files:
        print (f)

    sound = AudioSegment.from_mp3("test.mp3")

test()


  


  The output of the code from pycharm is :

  Is this actually a problem with pydub/ffmpeg/ffprobe, rather than the location of my mp3 file ? As I'm trying to package this project for Lambda, I've put executable versions of ffmpeg and ffprobe in the root of the project, rather than installed them to my OS. Before I did this, pydub complained that it couldn't find ffmpeg. It's now not complaining but, could I have chosen the wrong binary ?

  


  Any ideas ?

  


• How to determine which offsets changed in MP4 file after cutting a part of the MP4 file

  16 février 2021, par Muath

  This image displays each offset and the role of that offset in mp4 file.

  


  

  


  And this is MP4 file viewed in Hex-Editor :

  


  

  


  When cutting (as an example) first 60 seconds of that video or doing any cutting process, How can I know which offsets has been changed ?
