A Python wrapper for NDI® written in Cython
NDI® allows video and audio to be reliably sent and received over IP with minimal latency and very high quality. For more information see https://ndi.video.
This project aims to wrap most functionality of the NDI® SDK for use in Python. Due to the real-time nature of audio and video, nearly all of this library is written in Cython for performance purposes. By design, "cyndilib" may be used within other Cython code.

This project is available on PyPI with pre-built wheels for most platforms. Installing via pip would be the simplest method of installation:
pip install cyndilibAll of the necessary headers and Cython .pxd files will be included
in the distribution. This will allow for direct integration if using
Cython in your application using the cimport statement.
See the Cython documentation
for more details.
This may be necessary if a pre-built wheel is not available for your platform or Python version.
First clone or download the repository:
git clone https://github.com/nocarryr/cyndilib.git
cd cyndilibThe project can then be installed with:
pip install .All of the dependencies for building and installation should be automatically detected and installed (assuming your system supports the build metadata specifications introduced PEP 517).
Note
The . in the above command implies that you are in the root directory
of the cloned project. For other uses, the path to the project root may
be used instead.
There are quite a few sources to compile and by default, they will be compiled one at a time. There is currently not a direct way to tell pip to use multiple threads when compiling.
An environment variable CYNDILIB_BUILD_PARALLEL may be used to work around
this however. Its value can be either a specific number of threads to use
or "auto" to use all available cores:
CYNDILIB_BUILD_PARALLEL=auto pip install .More information on compilation and development can be found on the development page of the project documentation.
Documentation can be found at https://cyndilib.readthedocs.io. Since this project is still in its early stages of development however, a look at the example code and tests in the repository might be more useful.
