ntsc-encoder 0.1.0

NTSC encoder implemented as a pybind11 extension

ntsc-encoder (pybind11)

This directory builds the ntsc_encoder Python extension module using C++/pybind11.

Requirements

• Python 3.9+
• A C++ compiler + CMake 3.18+
• OpenCV development package (headers + libs)
  • macOS (Homebrew): brew install opencv
  • Ubuntu: sudo apt-get install libopencv-dev
• Build tools:
  • python -m pip install -U build twine

Build a wheel/sdist locally

From this directory (Code/Encoder):

python -m pip install -U pip
python -m pip install -U build twine scikit-build-core pybind11 numpy
python -m build

Artifacts will appear in dist/.

Check metadata:

twine check dist/*

Upload to PyPI

Recommended: upload to TestPyPI first.

# TestPyPI
python -m twine upload -r testpypi dist/*

# PyPI
python -m twine upload dist/*

You’ll need an API token configured in ~/.pypirc or exported via environment variables.

Building wheels for multiple platforms (recommended)

To avoid requiring end users to have a compiler + OpenCV dev libs, publish prebuilt wheels. Typical approach: GitHub Actions + cibuildwheel.

High-level steps:

1. Add cibuildwheel workflow
2. Build wheels for Linux (manylinux), macOS, Windows
3. Upload wheels + sdist with twine

If you want, I can add a ready-to-use GitHub Actions workflow for cibuildwheel.
