Streamlink

Streamlink is a command-line utility that can extract video streams and pipe them into a video player. The main purpose of streamlink, according to the official documentation, is to "allow the user to avoid buggy and CPU heavy flash plugins but still be able to enjoy various streamed content." Streamlink is written in python and works with various media players such as mpv, mplayer, and vlc.

Usage
Streamlink is a fairly simple program run from the command line with various options:


 * is the desired video player. The default player is vlc but mplayer and mpv are also available.


 * is the location of the desired stream. While the full list of supported plugins is extensive, some popular supported streams are bloomberg, mixer, twitch, and youtube.


 * is the desired available quality of the stream. The options allow either a specific quality, such as 720p, or a more vague quality such as high or low. Further, streamlink allows best or worst as alternatives.
