BulkTranscode

Transcode all your music library from one format to another while keeping the same folder structure.

Screenshots

Requirements

• Have ffmpeg in your PATH.

  • On Linux: Install the ffmpeg package via your package manager. You may need to install qt6base or qt5base if not already installed.
  • On Windows: Download and install the essential build from FFmpeg's official site. To have it in your PATH, either set the env. variables or copy ffmpeg.exe to C:\Windows\System32.

• Install PyQt6 with pip install pyqt6.

NOTE: As ffmpeg doesn't support embedding images in opus songs from flac songs (at least), opusenc is used as a replacement to ffmpeg for opus transcoding, so make it sure it is in the PATH if you want to transcode to opus. (On Windows, like ffmpeg, place the exe in System32. On Arch, it's the opus-tools package.
