zbl

zbl is a Rust and Python library which aims to make it easy to integrate CV libraries (such as OpenCV) with Windows Desktop apps for real-time processing. It does so by providing a simplified interface to Windows.Graphics.Capture.

This library is not well-tested against corner cases, and was only verified to work for a 'happy path' scenarios, so beware of bugs!

Python

Installation

pip install zbl

Alternatively, you can install suitable wheel from releases page.

Usage

from zbl import Capture

with Capture('visual studio code') as cap:
    frame = next(cap.frames())
    print(frame.shape)

The snippet above will capture a window which title contains the string visual studio code, take one frame (which is represented as a numpy array) and print its shape.

To run an example using OpenCV's highgui:

1. Install opencv-python
2. Run python -m zbl '<full or partial window name, case insensitive>'

Rust

See examples. Note: if you are getting OpenCV build errors when building the example, check out how to build OpenCV rust bindings.
