• 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.

• discord.py FFMPEG Option reconnect not found

  19 avril 2021, par Lukelele

  I'm working on a music bot using discord.py, I've looked online and found that I needed to pass in ffmpeg options into discord.FFmpegPCMAudio() for the bot to not stop half way through the song. However it returns an error "Option reconnect not found."

  


  vc = await ctx.message.author.voice.channel.connect()

ydl_opts = {
    'format': 'bestaudio/best',
    'outtmpl': 'C:/Luke/YoutubeDLAudio/audio.mp3',
    'postprocessors': [{
        'key': 'FFmpegExtractAudio',
        'preferredcodec': 'mp3',
        'preferredquality': '192'
    }],
    'prefer_ffmpeg': True,
    'keepvideo': True
}

ffmpeg_opts = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5','options': '-vn'}   # <---------------

with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    ydl.download([url])

vc.play(discord.FFmpegPCMAudio(executable="C:/Luke/ffmpeg/bin/ffmpeg.exe", source="C:/Luke/YoutubeDLAudio/audio.mp3", **ffmpeg_opts))    <--------------


  


  Does anyone know the problem ? Thanks for any help.
