• Converting files from a C++ base [closed]

  31 mars 2014, par Trevader24135

  I'm looking for a way to use ffmpeg from a program in C++ to allow super easy and accurate converting by typing only a couple of things in. I have everything all working, except the most important part. The actual converter. Here's my code so far - how do I use ffmpeg in C++ ?

  #include <iostream>
  
  #include <mp>
  
  
  
  using namespace std;
  
  
  
  int main()
  
  {
  
      std::string formatIn;
  
      std::string FormatOut;
  
      std::string confirm;
  
      cout &lt;&lt; "select format that file is currently in: mp3, gp3, mp4, flv" &lt;&lt; endl;
  
      cin >> formatIn;
  
      cout &lt;&lt; "original format = " &lt;&lt; formatIn &lt;&lt; endl;
  
      cout &lt;&lt; "choose your target format: mp3, gp3, mp4, flv" &lt;&lt; endl;
  
      cin >> FormatOut;
  
      cout &lt;&lt; "selected format = " &lt;&lt; FormatOut &lt;&lt; endl;
  
      cout &lt;&lt; "proceed? ";
  
      cin >> confirm;
  
      if(confirm == "yes") {
  
          cout &lt;&lt; "proceeding with operation:" &lt;&lt; endl;
  
          func convert();
  
      }
  
      else {
  
          if(confirm == "no") {
  
              cout &lt;&lt; "canceling,,," &lt;&lt; endl;
  
          }
  
      }
  
  }
  
  
  
  int convert()
  
  {
  
  
  
  }
  
  </mp></iostream>

• pydub unable to find the selected files

  4 février 2021, par big_Z_0909

  my code is as below

  


  import pydub
from pathlib import Path
import os, sys

pydub.AudioSegment.converter = r"D\\Anaconda3\\Scripts\\ffmpeg-2021-02-02-git-2367affc2c-essentials_build\\bin\\ffmpeg.exe"
pydub.AudioSegment.ffprobe = r"D\\Anaconda3\\Scripts\\ffmpeg-2021-02-02-git-2367affc2c-essentials_build\\bin\\ffprobe.exe"

my_file = "D:\\Anaconda3\\Scripts\\outcall\\luyinwenjian\\20210203.mp3"
song = pydub.AudioSegment.from_mp3(my_file)


  


  i downloaded the essential windows eddition of ffmpeg from the official website. i still cannot load the mp3 file from the document, got the FileNotFoundError : [WinError 2]. In the warning, it said that it could find ffprobe and ffmpeg, but in fact the path is correct in the code. Does anyone point out what exactly i went wrong here ?

  


• from_file function of pydub's audiosegment is only reading about 5 seconds of audio every time

  17 janvier 2020, par Johan Dingler

  I’m calling from_file on a .webm audio file in order to convert it to .mp3.
  The mp3 is successfully generated, however it’s always a bit short of 5 seconds long (between 4600-4800 ms everytime). I have no idea what is going on. After reading the original .webm into the audiosegment, I print it’s length and it’s 4600-4800. This is my code :

  pydub.AudioSegment.converter = '/opt/bin/ffmpeg'
  
  audioSegment = pydub.AudioSegment.from_file('/tmp/audioFile.{}'.format(event['audioFormat']), format=event['audioFormat'], codec=event['codec'])
  
  print('length of audio ', len(audioSegment))
  
  audioSegment.export('/tmp/output.mp3')

  Any ideas what might be going on ?
