• How do you suppress "Error in the pull function" messages to stdout ?

  23 mai 2021, par Vincent Lin

  I am working on making my Discord bot into a music player using youtube-dl. I got past the common problem of music being interrupted from an "Error in the pull function" by having ffmpeg reconnect upon this error. However, I cannot figure out how to suppress the error messages being sent to stdout anyway :

  


  [tls @ 0000023ea3564e80] Error in the pull function.
[https @ 0000023ea3560d80] Will reconnect at 327680 in 0 second(s), error=I/O error.


  


  My ytdl options and ffmpeg options are as follows :

  


  YTDL_OPTIONS = \
{"format": "bestaudio",
 "noplaylist": True,
 "quiet": True}
FFMPEG_OPTIONS = \
{"before_options": "-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5",
 "options": "-vn"}


  


  I experimented with various YTDL options like "no_warnings": False, "debug_printtraffic": False, "progress_hooks": [], etc. However, none of these additions worked. To be honest, I don't even know the source of these messages (youtube-dl or discord.py itself). Is there a way to suppress these messages ?

  


• Low CPU Usage with dbPoweramp Powershell

  21 janvier 2014, par Caulen

  I am using a program called dbPoweramp to convert music from within Powershell. I am using the documentation here which was all I could find for it when searching. Whenever I use the program itself to convert I get 100% CPU usage and it fully utilizes all eight threads. However, whenever I launch through the command line I only get something around 13% CPU usage. It obviously isn't desirable to have to launch the program manually because I am going for automation here. I have tried messing with the -processors argument but it has made no difference. Does anyone have any idea as to why that would be ?

  I have also tried using FFMPEG instead, but the CPU usage for FFMPEG is similarly low. If anyone could post code that would make FFMPEG utilize all eight cores that would work just as well.

  Here is the section of code that does the actual conversion, essentially it just searches for all flac, m4a, or mp3 files and then automatically converts them to variable bitrate quality 1 mp3s for streaming.

  $oldMusic = Get-ChildItem -Include @("*.flac", "*.m4a", "*.mp3") -Path $inProcessPath -Recurse #gets all of the music
  
  
  
  cd 'C:\Program Files (x86)\Illustrate\dBpoweramp'
  
  
  
  foreach ($oldSong in $oldMusic) {
  
      $newSong = [io.path]::ChangeExtension($oldSong.FullName, '.mp3')
  
      $oldSongPath = $oldSong.FullName 
  
      $newSongPath = "E:\Temp\$newSong"
  
      .\CoreConverter.exe  -infile= $oldSongPath -outfile= $newSong -convert_to= "mp3 (Lame)" -V $quality #converts the file

  }

  Thanks in advance !

• Can FFmpeg encode multiple files at once ?

  28 décembre 2016, par ivan

  I’m working on a shell script to encode the audio files in a given directory and output .flac files to another directory. My proof of concept loops through each file one by one and runs it through ffmpeg. I suspect there’s a way to pass the whole list of input files to ffmpeg in a single command, but haven’t been able to figure it out.

  My current version looks like this :

  #!/bin/sh
  
  
  
  encode_album() {
  
      local artist=$1; shift
  
      local album=$1; shift
  
      local in_dir="${HOME}/Music/raw-imports/${artist}/${album}"
  
      local out_dir="${HOME}/Music/library/${artist}/${album}"
  
  
  
      mkdir -p "${out_dir}"
  
  
  
      find "${in_dir}" -type f -name *.aiff | while IFS= read -r in_file; do
  
          local track_name=$(basename "${in_file}" .aiff)
  
          local out_file="${out_dir}/${track_name}.flac"
  
  
  
          encode_track "${in_file}" "${out_file}"
  
      done
  
  }
  
  
  
  encode_track() {
  
      local in_file=$1; shift
  
      local out_file=$1; shift
  
  
  
      null ffmpeg -i "${in_file}" -codec:a flac "${out_file}"
  
  }
  
  
  
  encode_album "Rolf Lislevand" "La Mascarade"

  This works, but do I need to feed these files into ffmpeg one by one, or is it capable of accepting a batch of files and processing them ?
