• Pyinstaller exe works halfway on another computer

  5 novembre 2022, par At Bay

  I wrote a code which uses FFMPEG and os, subprocess, datetime, speechrecognition, and xlsxwriter libraries. Below a brief sketch of the code - it goes through a directory of wav files and creates a transcription for X seconds in length and saves it into an excel sheet.
import os
import subprocess
import datetime
import speech_recognition as sr
import xlsxwriter

  


  def ffmpeg():
   #create clip
   subprocess.run(["ffmpeg", "-ss", starti, "-t", lengthi, "-i", filepathO, filepathNEW1])

   #convert to mono
   subprocess.run(["ffmpeg", "-i", filepathNEW1, "-ac", "1", filepathNEW2])
   
   #compres to 44.1 kHZ
   subprocess.run(["ffmpeg", "-i", filepathNEW2, "-ar", "44100", filepathNEW3])

def transcription():
    with sr.AudioFile(os.path.abspath(clippath)) as source:
       audio = r.record(source)  # read the entire audio file
       transcriptstring = str(r.recognize_google(audio, language = 'en', show_all=True))
       worksheet.write(tcol, transcriptstring)


#call functions in this order
for filename in os.listdir(ufolder):
   if (filename.endswith(".wav")):
       ffmpeg() #cuts clips, compresses to mono and 44.1 khz
       transcription() 

workbook.close()



  


  When I try to run the exe created by pyinstaller, I get the following error :

  


  Enter directory of wav files: C:\Users\myname\Downloads\&#xA;Enter clip start (seconds): 0&#xA;Enter desired clip length (seconds): 5&#xA;Traceback (most recent call last):&#xA;  File "cliptranscript.py", line 134, in <module>&#xA;  File "cliptranscript.py", line 47, in ffmpeg&#xA;  File "subprocess.py", line 503, in run&#xA;  File "subprocess.py", line 971, in __init__&#xA;  File "subprocess.py", line 1440, in _execute_child&#xA;FileNotFoundError: [WinError 2] The system cannot find the file specified&#xA;[13304] Failed to execute script &#x27;cliptranscript&#x27; due to unhandled exception!&#xA;</module>

• How to grab voice and video in ffmpeg/mplayer/mencoder ? [closed]

  4 février 2013, par Kill Kill

  My target is to grab voice and video via webcamera.
  There are three ways to do :

  1.ffmpeg

  ffmpeg -f oss -i /dev/dsp -f video4linux2 -r 25 -b 500000 -s 320x240 -i /dev/video0 out.mpg

  in my computer how to revise it ?

  2.mplayer :

  mplayer tv:// -tv driver=v4l2:input=0:width=640:height=480:fps=25 -vo x11  

  I can see the video when the command run, how can I save the output into a file and grab the voice ?

  3.mencoder :

• ffmpeg error when trying to convert mp4 to mp3 in python

  30 mai 2022, par Solphane

  from pytube import YouTube
from moviepy.editor import *

with open('test.txt') as f:
    lines = f.readlines()

for x in lines:
    yt = YouTube(x)
    yt.streams.filter(file_extension='mp4').first().download()

    mp4_file = f"{yt.title}.mp4"
    mp3_file = f"{yt.title}.mp4"

    audioclip.close()
    videoclip.close()
    
    title = f"{yt.author} {yt.title}"
    print(title)


  


  Trying to convert downloaded mp4 from Youtube videos to mp3 using pytube and moviepy. Downloading the mp4's works fine however I run into this error when the conversion part happens : https://i.imgur.com/JhJMQgR.png

  


  Tried updating ffmpeg, but it didn't help.
