• Use ffmpeg with python

  24 février 2014, par user2063350

  I have an ffmpeg setup on my pc, which streams mp3 with this code :

  ffmpeg -f dshow -i audio="Input device" -c:a libmp3lame -f mpegts udp://192.168.1.2:7777

  Also i have a server and I want to start recording stream to mp3 file whenever stream starts. Server is running all day long listening for pc to connect.
  How can I do this with python ? I want to create unique file with time and date in filename in filename each time stream starts. Can I do this using udp protocol or what protocol do You suggest me to use ? and what modules in python are helpful for this task ?

  subprocess.call('ffmpeg -y -i udp://192.168.1.2:7777 -acodec copy output.mp3')

  P.S. Sorry for my bad English.

• 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>
