Forked from Livestreamer, which is no longer maintained, Streamlink is a command line tool (and API) that can be used to stream videos from various streaming services, such as Twitch, YouTube Live and many more, and play them using your favorite video player, be it VLC, mpv, and more.

It looks like Livestreamer is no longer maintained, so a fork, called Streamlink, was created recently. There are no Ubuntu packages for the new fork, so I uploaded Streamlink to the main WebUpd8 PPA.

The PPA uses the Livestreamer Debian packaging, renamed for Streamlink, so the packaging credits go to Stefan Breunig, the Livestreamer Debian maintainer.

In case you're not familiar with Livestreamer, this is a command line utility (and API is also available) that pipes video streams from services such as Livestream, Twitch, UStream, Youtube Live and more, to video players like VLC, mpv, and so on.

The application comes with a very basic user interface, which allows dropping a torrent file or pasting a magnet link to start streaming it.

OBS Studio is a free, open source application which allows video recording and live streaming. The app can be used to stream to various popular websites such as Twitch.tv, YouTube, Hitbox.tv, Vaughn Live / iNSTAGIB.tv, DailyMotion, Connectcast.tv, GoodGame.ru, CyberGame.tv, CashPlay.tv along with custom streaming servers.

The original Open Broadcaster Software was rewritten, with the main goal of being multiplatform, along with a more powerful API and a more thorough feature set. The new multiplatform OBS Studio is currently in alpha and is available for Linux, Mac OS X and Windows.
