Installation

For Users

pip install mosaic-basis

For Development

# Clone the repository
git clone https://github.com/egoughnour/mosaic-basis.git
cd mosaic-basis

# Install in editable mode with development dependencies
pip install -e ".[dev]"

Development

Quick Start with Makefile

The project includes a Makefile for common development tasks:

# Show all available commands
make help

# Run all checks (format, lint, test)
make check

# Run tests
make test

# Run tests with coverage
make coverage

# Format code
make format

# Run linter
make lint

# Clean build artifacts
make clean

Running Tests

# Run all tests
pytest

# Run tests with coverage
pytest --cov=mosaic_basis --cov-report=html

# Run specific test file
pytest tests/test_basic.py

The richer test suite downloads a tiny public clip via yt-dlp to validate the timestamp-aware mosaic and preview flows. Make sure you have network access when running pytest; if the download fails (e.g., offline CI), the integration tests will automatically skip.

Downloading Videos via yt-dlp

Install the optional extra to enable the built-in downloader:

pip install -e ".[yt]"

You can then let the pipeline fetch a clip directly:

python src/video_omp_pipeline.py \
  --video ./work/input.mp4 \
  --download-url https://www.youtube.com/watch?v=V3-HL7MgzzA \
  --work ./work \
  --download-max-height 360

Use --download-overwrite to force a re-download if the target file already exists.

Code Quality

# Format code with black
black src tests

# Lint with ruff
ruff check src tests

# Type check with mypy
mypy src
