BD-to-AVP 3D Blu-ray Disc to Apple Vision Pro README
Introduction
This tool processes 3D video content from Blu-ray discs, ISO images, or MKV files, creating a final video file compatible with the Apple Vision Pro. It uses FFmpeg, MakeMKV, and Wine for video extraction, audio transcoding, and video stream merging to convert from Mpeg 4 MVC 3D video to MV-HEVC 3D video. The tool also injects 360° metadata into the video file for spatial media playback.
Quick install (or update)
To quickly install or update BD_to_AVP, run the following command in your terminal:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/cbusillo/BD_to_AVP/release/installer.sh)"
Prerequisites
Ensure the following are installed on your Mac (If not using the Quick Install):
- Apple Silicon Mac: A Mac with Apple Silicon, such as the M1, M1 Pro, or M1 Max (Maybe, installer currently requires Apple Silicon. If anyone can confirm that spatial-media-kit-tool works on Intel Macs, I can remove this requirement)
- macOS Sonoma: The latest version of macOS.
- Rosetta 2: A compatibility layer allowing Intel-based applications to run on Apple Silicon Macs.
- Python 3.12: The latest version of Python.
- Homebrew: The missing package manager for macOS (or Linux).
- FFmpeg: A complete, cross-platform solution to record, convert, and stream audio and video.
- Wine: A free and open-source compatibility layer allowing Windows programs to run on Unix-like operating systems.
- MakeMKV: For converting disc video content into MKV files.
- spatial-media-kit-tool: A tool for injecting 360° metadata into video files.
- MP4Box: A multimedia packager available for Windows, Mac, and Linux.
- MKVToolNix: A set of tools to create, alter, and inspect Matroska files.
Manual Installation (Out of date)
To set up your macOS environment for video processing, including creating and handling 3D video content, follow these steps to install the necessary tools using Homebrew and manual installation. This includes the installation of Homebrew itself, FFmpeg for video encoding and decoding, Wine for running Windows applications, MakeMKV for ripping Blu-ray and DVD to MKV, spatial-media-kit-tool for handling spatial media, and MP4Box for multimedia packaging.
# Install Rosetta 2
/usr/sbin/softwareupdate --install-rosetta --agree-to-license
# Install Homebrew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
# Install FFmpeg, MakeMKV, MP4Box, mkvtoolnix and Python 3.12
brew install ffmpeg makemkv mp4box mkvtoolnix python@3.12 --no-quarantine
# Install Wine
brew tap homebrew/cask-versions
brew install --cask --no-quarantine wine-stable
# Ensure Python 3.12 is correctly installed then create a virtual environment
python3.12 -m pip install --upgrade pip
python3.12 -m venv ~/.bd_to_avp_venv
# Activate the virtual environment and install BD_to_AVP
source ~/.bd_to_avp_venv/bin/activate
pip install bd_to_avp
# Create a symbolic link to the bd-to-avp command
ln -s ~/.bd_to_avp_venv/bin/bd-to-avp /opt/homebrew/bin/bd-to-avp
Usage
Navigate to the tool's directory in your terminal and execute the command with the required and optional parameters:
Command Syntax
bd-to-avp --source <source> [--source-folder <source-folder>] [options]
Parameters
--source: Source for a single disc number, MKV file path, or ISO image path (required).--source-folder: Source folder path. This option will recurively scan for image files or mkv files.
