Installation

Install the release

stanag4609 supports Python 3.10 through 3.14. A virtual environment keeps it separate from system packages:

python3 -m venv .venv
source .venv/bin/activate
python -m pip install stanag4609

py -m venv .venv
.venv\Scripts\Activate.ps1
python -m pip install stanag4609

Check the installed version and command-line tools:

python -m pip show stanag4609
stanag4609-verify --help

The core package has no required third-party Python dependencies.

Install optional integrations

Install an extra only when your application needs its runtime:

Extra Use it for
video-pyav Decode video frames through PyAV and FFmpeg
audio-pyav Decode supported compressed audio to PCM
ai-ultralytics Run Ultralytics prediction and tracking
ai-onnx Run an ONNX model with ONNX Runtime
ai-triton-http Call NVIDIA Triton over HTTP
ai-triton-grpc Call NVIDIA Triton over gRPC

For example:

python -m pip install 'stanag4609[video-pyav,ai-ultralytics]'

Install FFmpeg

The protocol library can parse and transform transport streams without FFmpeg. The reference player, demo generator, CSV muxer, and media-decoding adapters use FFmpeg for codec work.

Confirm that the executable is available:

ffmpeg -version

Use the packages published by the FFmpeg project or your operating system's package manager.

Upgrade

python -m pip install --upgrade stanag4609

The API remains pre-1.0. Read the changelog and API stability policy before adopting a new minor release.
