HD-DVD/Blu‑Ray Stream Extractor: Preserve High‑Quality MKV & FLAC Tracks

Extract Streams from HD‑DVD & Blu‑Ray: HD‑DVD/Blu‑Ray Stream Extractor Guide

What this guide covers

• Purpose: How to demux (extract) audio, video, subtitle, and metadata streams from HD‑DVD and Blu‑Ray discs/ISOs into lossless files for editing, archiving, or remuxing.
• Outcomes: You’ll end up with separate elementary streams or container files (e.g., H.264/VC‑1/AVC, LPCM/DTS/TrueHD/AC‑3, PGS/SubRip) suitable for further processing.

Required tools (common, cross‑platform)

• MakeMKV — read discs and produce MKV or dump stream IDs
• eac3to — audio/video demuxing and conversion (Windows; works under WINE on Linux/macOS)
• Mkvtoolnix (mkvmerge, mkvextract) — extract and remux MKV tracks
• tsMuxer or tsMuxeRGUI — sometimes needed for BDAV/TS formats
• BDSup2Sub / Subtitle Edit — convert PGS to SRT/ass (if needed)
• MediaInfo — inspect stream details and codecs
• FFmpeg — rewrap/convert streams when required

Typical workflow (prescriptive)

1. Rip disc to an ISO or MKV:
   • Use MakeMKV to read the disc and save main movie as an MKV (fast, preserves all tracks and chapters) or create a full disc ISO.
2. Inspect streams:
   • Open the MKV/ISO with MediaInfo to list video, audio, subtitle codecs, languages, and stream IDs. Note track numbers and codecs.
3. Demux tracks from MKV (preferred if you used MakeMKV):
   • Use mkvextract to extract each track:

     Code
     Copy CodeCopied
     mkvextract tracks input.mkv 0:video.h264 1:audio.dts 2:subtitle.sup 

   • Or use mkvmerge to remux selected tracks into a new MKV.
4. Extract from ISO/Blu‑ray structure (if not MKV):
   • Use eac3to to list and extract:

     Code
     Copy CodeCopied
     eac3to disc_folder eac3to discfolder 1: video.h264 2: audio.truehd 3: subtitle.sup 

   • tsMuxer can handle .m2ts streams when needed.
5. Convert or preserve audio:
   • Keep lossless audio (TrueHD, DTS‑HD MA, LPCM) if archiving.
   • Use eac3to or FFmpeg to convert to FLAC if a lossless container is preferred:

     Code
      ffON2NH02oMAcqyoh2UU MQCbz04ET5EljRmK3YpQ CPXAhl7VTkj2dHDyAYAf” data-copycode=“true” role=“button” aria-label=“Copy Code”>Copy CodeCopied
     eac3to audio.thd audio.wav flac audio.wav 

6. Convert subtitles (PGS) to text (optional):
   • Use BDSup2Sub to convert to .sub/.idx or Subtitle Edit with OCR to produce SRT/ASS.
7. Remux into target container:
   • Use mkvmerge to assemble selected video, audio, subtitle files into a final MKV:

     Code
     Copy CodeCopied
     mkvmerge -o final.mkv –language 0:eng video.h264 –language 0:eng audio.dts –language 0:eng subtitle.srt
