• Recursively Converting FLAC to MP3 Using FFmpeg While Maintaining Metadata and Directory Structure on Windows

  20 mars 2017, par elgo2006

  I’m trying to use FFmpeg to convert all of the .flac’s in my music library to .mp3’s while maintaining the metadata and directory structure of the original files. I’ve got everything working so far except for maintaining the directory structure.

  So far I have :

  @echo off
  
  rem Copies the original directory structure from F:\Music to D:\Music
  
  xcopy /T %1 %2
  
  rem Recursively converts files with .flac extension from F:\Music to .mp3 in D:\Music
  
  for /R %1 %%i in (*.flac) do (
  
      echo Currently converting "%%~nxi"
  
      ffmpeg -v quiet -i "%%i" -q:a 0 -map_metadata 0 -id3v2_version 3 -write_id3v1 1 "%2\%%~ni.mp3"
  
  )
  
  echo Completed.
  
  pause

  I feel like my issue is coming from having my FFmpeg output as "%2\%%~ni.mp3" , however I can’t get it to maintain the original directory structure. I have played around with dpni as options for the output, but then it does not convert correctly.

  The .bat is being executed from the command line as convert F:\Music D:\Music

  All music in the original directory has the structure F :\Music\Artist Name\Album Name\Song.flac and I want it to end up as D :\Music\Artist Name\Album Name\Song.mp3.

  Alternatively, is there a way to convert the .flac to an .mp3 within the same directory as the source file and then delete the flac ?

• FFMPEG Merge a video that has sound with an mp3 audio file outputs audio out of sync [duplicate]

  23 février 2021, par Mahmoud Eidarous

  An example for further explanation :
I'm recording a video singing at the same time the singer sings in a song.
So, I have a video file(Me singing) and the audio file(the song).

  


  I tried this simple command :

  


  -i $video-i $audio-c copy -map 0:0 -map 1:0 -shortest output.mp4


  


  But, it gives an output with the video sound muted(my voice muted).

  


  And I want something more advanced to control the volume of each sound, and add filter to make the output sound sounds like it was recorded in a studio.. so after a long search through the documentation and similar questions, I made up this command here..

  


  -i $video -i $audio -filter_complex "[0:a]aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=0.8[a1]; [1:a]aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=4[a2]; [a1][a2]amerge,pan=stereo|c0code>

  


  It gives a video output with audio out of sync. (My voice doesn't match the singer).

  


  Any help would be really appreciated !

  


• Uncomplete path recognition (FFmpeg) [duplicate]

  23 septembre 2022, par Francesco Battisti

  The script should download an entire playlist (only one song for this test) from YT and convert all the downloaded MP4 to MP3 :

  


  from distutils import extension
from pytube import Playlist
import os

link = input("Enter YouTube Playlist URL: ")

yt_playlist = Playlist(link)

for video in yt_playlist.videos:
    downloaded_file = video.streams.filter(only_audio=True).first().download(r"C:\Users\Francesco\Desktop\Music\JC's\+++NEW+++")
    file, extension = os.path.splitext(downloaded_file)
    # Convert video into .mp3 file
    os.system('ffmpeg -i {file}{ext} {file}.mp3'.format(file=file, ext=extension))


  


  Now, when I put the playlist's url in input, the script downloads the song but it can't convert it because :

  


  C:\Users\Francesco\Desktop\Music\JC's\+++NEW+++\Ariete: No such file or directory


  


  but the right path is :

  


  C:\Users\Francesco\Desktop\Music\JC's\+++NEW+++\Ariete - LULTIMA NOTTE Testo  Lyrics


  


  so it stops when is there a space in directory name...
