• Converting .aif to mp3 using pydub

  22 mars 2019, par Nick Wetaski

  I want to convert a bunch of music files located on my desktop (however trying to convert just one of them is the first step) from .aif to .mp3 however I am receiving an error code 1 from ffmpeg.

  I have ffmpeg and pydub installed

  Code :

  from os import path
  
  from pydub import AudioSegment
  
  from pydub.utils import which
  
  
  
  AudioSegment.converter = which("ffmpeg")
  
  
  
  aif_audio = AudioSegment.from_file("C:/Users/Nick/Desktop/scratch/landonmusic1.aif", format="aif")
  
  
  
  aif_audio.export("C:/Users/Nick/Desktop/scratch/landonmusic1.mp3", format="mp3")

  I am receiving the following feedback from Python Terminal :

  S C:\Users\Nick\OneDrive\ProgrammingProjects> & C:/Users/Nick/AppData/Local/Programs/Python/Python37-32/python.exe c:/Users/Nick/OneDrive/ProgrammingProjects/Classes/MusicFileConverter.py

      p.returncode, p_err))
  
  pydub.exceptions.CouldntDecodeError: Decoding failed. ffmpeg returned error code: 1
  
  </module>

• FFmpeg commands work for root only(centos 6.10)

  20 mars 2019, par Prashant Hanamghar

  I have dedicated server. I have installed FFmpeg on my root. All commands related to FFmpeg works if I logged in as root but no command is working if I logged in as user. I have tried adding one user to sudoers also. Also I want to use FFmpeg commands in PHP shell_exec() or exec(). Can someone tell me the solution. Thanks in advance.

  user command :

  $ ffmpeg

  output :

  -bash: ffmpeg: command not found

  root command :

  $ ffmpeg

  output

• ffmpeg convert video in a path with different name

  16 mars 2019, par tour travel

  Using ffmpeg in php with shell_exec and want to convert video in a path that different with where script is run. php script is in /s/m/video.php :

  <?php
  
  if(isset($_GET["videoTools"])){
  
  
  
      $user = $_GET["user"];
  
      $uid = $_GET["uid"];
  
      $vid = $_GET["vid"];
  
  
  
      $uploaddir = '/seller/uploads/'.$user.'/'.$uid.'/';
  
  
  
      echo shell_exec('ffmpeg -i '.$uploaddir.$vid.'-vid.mp4 -i /s/m/logo.png \
  
      -filter_complex "hflip[flipped];[flipped]overlay=x=20:y=20" \
  
      -s 480x320 -acodec aac -strict -2 -ac 1 -ar 16000 -r 13 -ab 32000 -aspect 3:2 \
  
      -strict -2 '.$uploaddir.$vid.'-vid-resized.mp4');
  
  }
  
  ?>

  And this script called by ajax in /s/a/index.php :

      $.ajax({
  
          url: "/s/m/video.php?videoTools",
  
          type: "GET",
  
          data: {vid: json[0], uid: json[1], user: json[2]},
  
          success: function(data){
  
           // success
  
          }
  
      });

  And for example I want to convert video in this path /s/uploads/91/768/2019-2-2_668-vid.mp4

  Problems :

  This not working, because look like ffmpeg not find video and logo in a path / Also look like ffmpeg not accepet video with - or _ or etc.

  No related error log, but video not generated and script not working. Any idea ?
