• avformat/argo_asf : don't check file version

  10 août 2020, par Zane van Iperen

  avformat/argo_asf : don't check file version
  It has no bearing on structure. Determined by looking at the ASF
  
  files from several Argonaut games :
  
    - FX Fighter,
  
    - Croc,
  
    - Croc 2,
  
    - The Emperor's New Groove, and
  
    - Disney's Aladdin in Nasira's Revenge
  The only versions that appear are 1.1, 1.2, and 2.1, and their
  
  structure is identical.

• 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

• FFMPEG Batch Copy Metadata from "Folder1File1.mp3" to "Folder2File1.mp3" in different folders

  27 février 2020, par Vektorz

  I have two separate files in separate folders with the same name and I would like to transfer the metadata from the file in "folder1" to "folder2".
  Then I would like to add a whole bunch of files fitting this same format and batch transfer all of the metadata information.

  From a stack exchange thread I’ve tried :

  "The following script will loop through the the files in one directory, find corresponding files in a second directory and then combine these two files into a third output directory
  
  
  
  dir1=FIRST DIRECTORY
  
  dir2=SECOND DIRECTORY
  
  output=OUTPUT DIRECTORY
  
  for file in $(ls $dir1); do
  
    ffmpeg -i "$dir1/$file" -i "$dir2/$file" -map 1 -c copy \
  
     # copies all global metadata from in0.mkv to out.mkv  
  
     -map_metadata 0 \
  
     # copies video stream metadata from in0.mkv to out.mkv
  
     -map_metadata:s:v 0:s:v \
  
     # copies audio stream metadata from in0.mkv to out.mkv
  
     -map_metadata:s:a 0:s:a \
  
     "$outdir/$file"
  
  done"

  But for the life of me I cannot get this to work properly and it is a bit overkill. He continues on saying :

  If you want to make something reuseable you could put this in a script with the following header (remove the assignment for dir1, dir2 and output in the script above). And then call it as script.sh dir1 dir2 outdir
  
  
  
  #!/bin/bash
  
  set -x errexit # exit immediately on error
  
  dir1="$1"
  
  dir2="$2"
  
  output="$3"

  And I am totally lost. Can someone please help me to get this to work and walk me through it a bit easier as I’m fairly inexperienced with code/FFMPEG.

  Thank you.
