node-screencapturekit

Filter and select Mac screen content and stream it to NodeJS using Apple's ScreenCaptureKit.

Use the ScreenCaptureKit framework to add support for high-performance frame capture of screen ~and audio content~ to your Mac NodeJS app. The framework gives you fine-grained control to select and stream only the content that you want to capture. As a stream captures ~new video frames and audio samples, it passes them to your app as CMSampleBuffer objects that contain the media data and its related metadata. ScreenCaptureKit also provides a macOS-integrated picker for streaming selection and management, SCContentSharingPicker~.

Using

This is early days for the project. Install via Git:

npm add git://github.com/justjake/node-screencapturekit

There may be a version available in NPM but it probably is out of date and/or not code signed correctly.

For a demo of the available features, see the demo or read the source code.
