ndi-python

NewTek NDI Python wrapper

Installation

ndi-python is support pypi package now. https://pypi.org/project/ndi-python/
So you can install it using pip if it is a supported environment.

pip install ndi-python

The supported environment is as follows.

• Windows x64 Python(3.10-3.14)
• macOS arm64(>=13.0) Python(3.10-3.14)
• Linux x64,aarch64,armv7l Python(3.10-3.14)

Setup Avahi

Linux requires Avahi to search for NDI sources.
Please install according to your environment.

Ubuntu

sudo apt install avahi-daemon
sudo systemctl enable --now avahi-daemon

Arch Linux

sudo pacman -S avahi
sudo systemctl enable --now avahi-daemon

Run examples

I've ported some examples to python.
You can try it by running the ndi-python examples.

git clone https://github.com/buresu/ndi-python.git
cd ndi-python/example
pip install -r requirements.txt
python find.py

Capture NDI|HX Source

Capturing NDI|HX sources requires an environment capable of decoding H.264 video.
On Linux, the NDI SDK dynamically loads FFmpeg libraries internally for H.264 decoding.
Please install a compatible FFmpeg version that matches the version required by your NDI SDK.

You can check which FFmpeg version is required with a command similar to the following:

strings /path/to/ndilib/libndi.so | grep libavcodec
out: libavcodec.so.61

In this case, libavcodec.so.61 corresponds to FFmpeg 7.x.

Development

Install NDI SDK

NDI SDK is required for development.
You should install according to your environment.

Windows, Mac, Ubuntu

Donwload and install NDI SDK.
https://ndi.video/for-developers/ndi-sdk/download/

Arch Linux

yay -S ndi-sdk

Build

git clone https://github.com/buresu/ndi-python.git
cd ndi-python
pip install .

If you need to set the NDI SDK directory explicitly:

CMAKE_ARGS="-DNDI_SDK_DIR=/path/to/ndisdk" pip install .

To build for a specific Python version:

CMAKE_ARGS="-DNDI_SDK_DIR=/path/to/ndisdk" /path/to/python3.12 -m pip install .
