Multi-track media container splitter, stream extractor & lossless remuxer

Media Container Stream Demuxer is a desktop multi-track multimedia container splitter, elementary stream extractor, chapter editor, and lossless remuxing workbench for Linux. An independent Linux alternative inspired by desktop media splitter utilities, it inspects every video, audio, subtitle, and chapter track inside Matroska (.mkv), MP4 (.mp4), Ogg (.ogg), WebM (.webm), MPEG-TS (.ts), and QuickTime (.mov) containers and splits or remuxes selected streams without re-encoding.

Key Features:

  • Multi-Stream Container Inspection: Lists every video, audio, subtitle, data, and chapter stream with codec profile, resolution, frame rate, sample rate, channel layout, bitrate, language tag, track title, and disposition flags alongside video frame previews.
  • Lossless Elementary Stream Demuxing: Extracts chosen video, audio, and subtitle tracks directly to elementary or single-stream files (.h264, .hevc, .aac, .flac, .opus, .ac3, .srt, .ass, .vtt, .mka, .mks) using direct stream copy (-c copy) with zero quality loss.
  • Lossless Multi-Track Remuxer & Chapter Editor: Remuxes any subset of video, audio, and subtitle tracks with editable language/title tags, keyframe trim ranges, and custom FFMetadata chapter markers into clean .mkv, .mp4, .webm, .mov, or .ts containers.
  • Local Media Discovery & Manifest Reports: Browses local media folders to compare container formats and exports complete stream and chapter manifests to JSON and CSV files.
