Forked from Livestreamer, which is no longer maintained, Streamlink is a command line tool (and API) that can be used to stream videos from various streaming services, such as Twitch, YouTube Live and many more, and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It looks like Livestreamer is no longer maintained, so a fork, called Streamlink, was created recently.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.
