To use screen capture or a browser tab as an input source, you must first install the chrome extension for screensharing, and restart chrome.
To install, go to chrome://extensions/ Click "Load unpacked extension", and select the "extensions" folder in "screen-capture-extension" in this repo. Restart chrome. The extension should work from now on without needing to reinstall.
To run locally, you must have nodejs and npm installed. Install from: https://nodejs.org/en/
Download the repository, open terminal, and enter directory
npm install -d
The repo contains a desktop version built using nw.js, and a browser-based version. Some features, such as broadcast and relaying OSC channels, are only available in the desktop version.
Run the browser version:
npm run start-local
To run the desktop version, first install nwjs as a command-line utility.
npm install -g nwjs
Then, install version 0.28.0 of nwjs:
nw install 0.28.0-sdk
Run the desktop app:
npm run start-nw
To develop either version, open a separate command line and type
npm run watch
