Lossless Matroska (.mkv) multi-track multiplexer, demuxer & chapter editor

A dedicated Matroska (.mkv) multi-track stream multiplexer, track extractor, and chapter editor for Linux. A lightweight Linux alternative to MKVToolNix GUI for lossless Matroska stream muxing, track metadata editing, and demuxing.

Key features powered by bundled FFmpeg:

  • Lossless Matroska (.mkv) multiplexing (-c copy) combining multiple video, audio, and subtitle (.srt, .ass, .vtt) sources without re-encoding.
  • Interactive stream table to inspect codecs, toggle included tracks (-map), edit ISO 639-2 language codes, set custom track titles, and configure default track disposition flags.
  • Live FFmpeg multiplexing command-line preview updating automatically as tracks and metadata change.
  • Lossless Track Extractor / Demuxer to export embedded audio, subtitle, or video streams into standalone files.
  • Container Chapters & Metadata Inspector to examine stream headers and remux custom Matroska chapter markers.
