Windows Package Builder

Automated build system for creating Windows portable packages of Pixelle-Video.

Quick Start

Prerequisites

• Python 3.11+ (for running the build script)
• PyYAML: pip install pyyaml
• Internet connection (for downloading Python, FFmpeg, etc.)

Build Package

# Basic build
python packaging/windows/build.py

# Build with China mirrors (faster in China)
python packaging/windows/build.py --cn-mirror

# Custom output directory
python packaging/windows/build.py --output /path/to/output

Configuration

Edit config/build_config.yaml to customize:

• Python version
• FFmpeg version
• Excluded files/folders
• Build options
• Mirror settings

Output

The build process creates:

dist/windows/
├── Pixelle-Video-v*-win64/             # Build directory (version number varies)
│   ├── python/                         # Python embedded
│   ├── tools/                          # FFmpeg, etc.
│   ├── Pixelle-Video/                  # Project files
│   ├── data/                           # User data (empty)
│   ├── output/                         # Output (empty)
│   ├── start.bat                       # Main launcher
│   ├── start_api.bat                   # API launcher
│   ├── start_web.bat                   # Web launcher
│   └── README.txt                      # User guide
├── Pixelle-Video-v*-win64.zip          # ZIP package (version number varies)
└── Pixelle-Video-v*-win64.zip.sha256   # Checksum (version number varies)

Build Process

The builder performs these steps:

1. Download Phase

   • Python embedded distribution
   • FFmpeg portable
   • Cached in .cache/ for reuse

2. Extract Phase

   • Extract Python to build/python/
   • Extract FFmpeg to build/tools/ffmpeg/

3. Prepare Phase

   • Enable site-packages in Python
   • Install pip
   • Install uv (if configured)

4. Install Phase

   • Install project dependencies using uv/pip
   • Pre-install all packages

5. Copy Phase

   • Copy project files (excluding test/docs/cache)
   • Generate launcher scripts from templates
   • Create empty directories

6. Package Phase

   • Create ZIP archive
   • Generate SHA256 checksum

Templates

Launcher script templates in templates/:

• start.bat - Main Web UI launcher
• start_api.bat - API server launcher
  
• start_web.bat - Web UI only launcher
• README.txt - User documentation

Templates support placeholders:

• {VERSION} - Project version
• {BUILD_DATE} - Build timestamp

Cache

Downloaded files are cached in .cache/:

.cache/
├── python-3.11.9-embed-amd64.zip
├── ffmpeg-6.1.1-win64.zip
└── get-pip.py

Delete cache to force re-download.

Troubleshooting

Build fails with "PyYAML not found"

pip install pyyaml

Downloads are slow

Use China mirrors:

python build.py --cn-mirror

Dependencies installation fails

Check:

1. Internet connection
2. PyPI mirrors accessibility
3. Project dependencies in pyproject.toml

ZIP creation fails

Ensure:

1. Sufficient disk space
2. Write permissions to output directory
3. No files are locked by other processes

Advanced Usage

Custom Configuration

Create custom config file:

cp config/build_config.yaml config/my_config.yaml
# Edit my_config.yaml
python build.py --config config/my_config.yaml

Skip ZIP Creation

Edit build_config.yaml:

build:
  create_zip: false

Include Chrome Portable

Edit build_config.yaml:

chrome:
  include: true
  download_url: "https://path/to/chrome-portable.zip"

Maintenance

Update Python Version

Edit config/build_config.yaml:

python:
  version: "3.11.10"
  download_url: "https://www.python.org/ftp/python/3.11.10/python-3.11.10-embed-amd64.zip"

Update FFmpeg Version

Edit config/build_config.yaml:

ffmpeg:
  version: "6.2.0"
  download_url: "https://github.com/BtbN/FFmpeg-Builds/releases/download/..."

Distribution

To distribute the package:

1. Upload ZIP file to release page
2. Include SHA256 checksum for verification
3. Provide installation instructions

Users verify download:

# Windows PowerShell
Get-FileHash Pixelle-Video-v*-win64.zip -Algorithm SHA256

Compare with .sha256 file.

License

Same as Pixelle-Video project license.
