Livestreamer Twitch GUI is a Twitch.tv browser. The application uses Livestreamer under the hood, is powered by Node.js and Chromium, and is available for Linux, Windows and Mac. According to its description, the main reason behind creating this application is to allow using your favorite video player, like VLC, Totem, mpv, and others to watch Twitch.tv streams (the app even allows watching multiple streams at once) instead of Flash. […] Desktop notifications are included as well, so you can be notified when a channel you follow comes online.
