• Pydub wma to mp3 fixing "library configuration mismatch"

  21 juillet 2020, par Rich

  Python novice, looking to change that.

  


  I am trying to convert a song from wma to mp3 while keeping the metadata on the song. Here is my code.

  


  #musicproject.py
import os
import glob
from pydub import AudioSegment

music_dir ='/mnt/c/renameproject'
extension_list = ('*.wma')

os.chdir(music_dir)
for extension in extension_list:
    for song in glob.glob(extension):
        mp3_filename = os.path.splitext(os.path.basename(song))[0] + '.mp3'
        AudioSegment.from_file(song).export(mp3_filename, format='mp3')


  


  The program finishes and the song is written as an mp3 in the same folder and plays just fine. Unfortunately all of the metadata has been stripped from the song. I get the following warning at the command line when I run the program. My theory on the problem is that there is a mismatch between pydub and ffmpeg as far as the metadata library goes so pydub is feeding in something that ffmpeg doesn't understand so it pukes. I have absolutely no idea what steps to take to fix it from here. Any breadcrumbs would be appreciated. Thanks.

• FFMPEG "Could not allocate memory" Errors through php

  10 décembre 2019, par Applepiee

  I’ve tried to find a solution online for days now but cannot find any solution.

  I just switched server (Intel Xeon to AMD) and since the switch I’ve not been able to get ffmpeg conversions working through the php script. ffmpeg was the exact same version and all php settings are set.

  All commands that the script executes (copied from log files) were tried in shell and executed with no problems.

  The errors look like this :

• FFMPEG "listfile.txt : Invalid data found when processing input" concat error

  18 juillet 2019, par Léandre

  I have a txt file, where I have all my mp4 file to concat with ffmpeg. I saw the documentation of FFMPEG but I don’t see where I did something wrong.

  Here is my txt file :

  file '/home/leandre/PycharmProjects/video_test/1.mp4'
  
  file '/home/leandre/PycharmProjects/video_test/2.mp4'
  
  file '/home/leandre/PycharmProjects/video_test/3.mp4'
  
  file '/home/leandre/PycharmProjects/video_test/4.mp4'
  
  file '/home/leandre/PycharmProjects/video_test/5.mp4'

  file '/home/leandre/PycharmProjects/video_test/9.mp4'

  And this is my ffmpeg command : ffmpeg -f concat -safe 0 -i listfile.txt -c copy out_concat.mp4

  And my error listfile.txt: Invalid data found when processing input
