This project implements an Chromecast receiver app, which allows casting of NHL Gamecenter Live streams on a Chromecast device. Since it's a personal and prototypical project, there is no guarantee for it to work.
This app does not circumvent the DRM content protection of NHL Gamecenter Live in any way. You need a valid NHL Gamecenter Live subscription to start this app.
Setup a web server serving the files in default/static. You can also use this repository to deploy a Heroku application. Using the Google Cast SDK Developer Console retrieve an Application ID. Be sure to serve the receiver application via HTTPS, otherwise decryption of live games won't work.
