• Converting mkv files to mp4 with ffmpeg-python

  16 mai, par myth0s

  I have a lot of .mkv files that I'm trying to convert to .mp4, so I decided to try and program a solution in python. After a few hours, trying to figure out how to copy the subfolders too, I gave up on it and decided to stick with converting individual subfolders, and then copying them over to another directory.

  


  I've made a simple script, that should convert .mkv files that are in the same folder as the script. However, I keep getting this error :

  


  


  FileNotFoundError : [WinError 2] The system cannot find the file specified

  


  


  Here's my code :

  


  import os
import ffmpeg

start_dir = os.getcwd()

def convert_to_mp4(mkv_file):
    no_extension = str(os.path.splitext(mkv_file))
    with_mp4 = no_extension + ".mp4"
    ffmpeg.input(mkv_file).output(with_mp4).run()
    print("Finished converting {}".format(no_extension))

for path, folder, files in os.walk(start_dir):
    for file in files:
        if file.endswith('.mkv'):
            print("Found file: %s" % file)
            convert_to_mp4(file)
        else:
            pass

• Convert multible files with threading ffmpeg in Python

  21 mars 2020, par Florian

  I’m trying to convert mp3 files to m4a. The files are in different folders like MainFolder(folder1, folder2,...)

  It works already but is very slow because it is converting file by file.

  import os
  
  import sys
  
  
  
  path = "/Users/flo/Desktop/test"
  
  
  
  for root, dir, files in os.walk(path):
  
      dir.sort()
  
      files.sort()
  
  
  
      for file in files:
  
          if file.find('.mp3') != -1:
  
              os.system('ffmpeg -i ' +'"' +root +'/' +file +'" ' +'-c:v copy -c:a libfdk_aac -b:a 300k '  +'"' +root +'/' +file[:-4] +'.m4b' +'"')

  Now I would like to implement multitasking.

  import os
  
  import sys
  
  import threading
  
  import queue
  
  
  
  path = "/Users/flo/Desktop/test"
  
  def convert(file):
  
      if file.find('.mp3') != -1:
  
          os.system('ffmpeg -i ' +'"' +root +'/' +file +'" ' +'-c:v copy -c:a libfdk_aac -b:a 300k '  +'"' +root +'/' +file[:-4] +'.m4b' +'"')
  
  
  
  for root, dir, files in os.walk(path):
  
      dir.sort()
  
      files.sort()
  
  
  
      q = queue.Queue
  
      threads = [threading.Thread(target=convert(file)) for file in files]
  
      for t in threads:
  
          t.start()
  
  
  
      for file in files:
  
          q.put(file)
  
  
  
      for file in files:
  
          q.put('stop')
  
  
  
      q.join()
  
  
  
      for t in threads:
  
          t.join()

  But I got the error message :

  File "/var/folders/r6/z5f_jcf139b8fh2n8m4lznlm0000gn/T/atom_script_tempfiles/30127c90-6b13-11ea-af8a-432a34b059ac", line 31
