README.md

The provided text outlines a process for high-speed DVD ripping using FFmpeg with hardware acceleration, specifically leveraging NVENC for Nvidia GPUs or V4L2 for Raspberry Pi [1.2]. The guide details steps to identify and extract the main movie track, secure subtitle color palettes from .IFO files, and provides bash scripts for encoding the content into MKV format [1.2]. The guide also includes instructions for script installation and execution, alongside important notes regarding canvas size, language tags, and the necessity of the .IFO file for correct subtitle display [1.2]. More information is available on the GitHub repository.

Via mpv (empfohlen)

mpv dvdnav:// --dvd-device=/dev/sr0 --cache=no --stream-dump=output.vob

cp /media/dvd/VIDEO_TS/VTS_07_0.IFO default.IFO

Verwende Code mit Vorsicht.

Schritt 3: Encoding-Skripte Option A: NVIDIA GPU (CUDA/NVENC) Ideal für PC-Nutzer mit NVIDIA-Grafikkarte. Nutzt hevc_nvenc für 10-Bit HEVC.

ripping_nvenc.sh

Nutzung: ./ripping_nvenc.sh output.vob

#!/bin/bash
for file in "$1"; do
  ffmpeg -hwaccel nvdec -hwaccel_output_format nv12 \
  -probesize 1200M -analyzeduration 1210M \
  -ifo_palette default.IFO -canvas_size 720x576 \
  -i "$file" -ss 00:00:02 \
  -map 0:v? -c:v hevc_nvenc -profile:v main10 -preset p5 -tune hq -b:v 3M -maxrate 5M -aspect 16:9 \
  -map 0:a? -c:a libfdk_aac -b:a 128k \
  -map 0:s? -scodec dvdsub \
  -metadata title="$file" -f matroska "${file%.*}_main10.mkv"
done

Verwende Code mit Vorsicht.

Option B: Raspberry Pi (V4L2/DRM) Optimiert für den Broadcom-Chip des Raspberry Pi. ripping_rpi.sh

#!/bin/bash
# Nutzung: ./ripping_rpi.sh output.vob
for file in "$1"; do
  ffmpeg -hwaccel drm -hwaccel_output_format drm_prime \
  -probesize 400M -analyzeduration 410M \
  -ifo_palette default.IFO -canvas_size 720x576 \
  -i "$file" -ss 00:00:02 \
  -map 0:v? -c:v h264_v4l2m2m -b:v 3M -num_capture_buffers 92 -aspect 16:9 \
  -map 0:a? -c:a libfdk_aac -b:a 128k \
  -map 0:s? -scodec dvdsub \
  -f mp4 "${file%.*}.mp4"
done

#!/bin/bash
# Nutzung: ./ripping_nvenc_51.sh dein_video.vob

for file in "$1"; do
  ffmpeg -hwaccel nvdec -hwaccel_output_format nv12 \
    -probesize 1200M -analyzeduration 1210M \
    -ifo_palette default.IFO -canvas_size 720x576 \
    -i "$file" -ss 00:00:02 \
    -map 0:v? -c:v hevc_nvenc -profile:v main10 -preset p5 -b:v 3M -maxrate 5M -aspect 16:9 \
    -map 0:a? -c:a ac3 -b:a 640k \
    -map 0:s? -c:s dvdsub \
    -metadata title="$file" \
    -f matroska "${file%.*}_51.mkv"
done

chmod +x ripping_nvenc_51.sh

cat << 'EOF' > ripping_rpi.sh

chmod +x ripping_rpi.sh

Verwende Code mit Vorsicht.

Schritt 4: Installation & Ausführung Rechte vergeben: chmod +x ripping_nvenc.sh Global verfügbar machen (optional): sudo cp ripping_nvenc.sh /usr/local/bin/ripping-dvd Starten: ripping-dvd output.vob Wichtige Hinweise: Canvas Size: Falls die Untertitel verschoben sind, prüfe die Auflösung deiner Quelle mit ffprobe und passe -canvas_size (z. B. 720x480 für NTSC) an. Sprach-Tags: Diese kannst du je nach DVD im FFmpeg Metadata Guide anpassen.
