Streamlink is a command-line application, which means that the commands described here should be typed into a terminal. On Windows, you have to open either the Command Prompt, PowerShell or Windows Terminal, on macOS open the Terminal app, and if you're on Linux or BSD you probably already know the drill.

The way Streamlink works is that it's only a means to extract and transport the streams, and the playback is done by an external video player. Streamlink works best with VLC or mpv, which are also cross-platform, but other players may be compatible too, see the Players page for a complete overview.

Now to get into actually using Streamlink, let's say you want to watch the stream located on twitch.tv/day9tv, you start off by telling Streamlink where to attempt to extract streams from. This is done by giving the URL to the command streamlink as the first argument:

$ streamlink twitch.tv/day9tv
[cli][info] Found matching plugin twitch for URL twitch.tv/day9tv
Available streams: audio, high, low, medium, mobile (worst), source (best)

Note

You don't need to include the protocol when dealing with HTTP(s) URLs, e.g. just twitch.tv/day9tv is enough and quicker to type.

This command will tell Streamlink to attempt to extract streams from the URL specified, and if it's successful, print out a list of available streams to choose from.

In some cases (see Supported streaming protocols), local files are supported using the file:// protocol, for example a local HLS playlist can be played. Relative file paths and absolute paths are supported. All path separators are /, even on Windows.

$ streamlink hls://file://C:/hls/playlist.m3u8
[cli][info] Found matching plugin stream for URL hls://file://C:/hls/playlist.m3u8
Available streams: 180p (worst), 272p, 408p, 554p, 818p, 1744p (best)

To select a stream and start playback, simply add the stream name as a second argument to the streamlink command:

$ streamlink twitch.tv/day9tv 1080p60
[cli][info] Found matching plugin twitch for URL twitch.tv/day9tv
[cli][info] Opening stream: 1080p60 (hls)
[cli][info] Starting player: vlc

The stream you chose should now be playing in the player. It's a common use case to just want to start the highest quality stream and not be bothered with what it's named. To do this, just specify best as the stream name and Streamlink will attempt to rank the streams and open the one of highest quality. You can also specify worst to get the lowest quality.

Now that you have a basic grasp of how Streamlink works, you may want to look into customizing it to your own needs, such as:
