streams(url, **params)¶

Attempts to find a plugin and extract streams from the url.

params are passed to Plugin.streams().

Raises NoPluginError if no plugin is found.

Plugins¶

class streamlink.plugin.Plugin(url)¶

A plugin can retrieve stream information from the URL specified.

Parameters:	url – URL that the plugin will operate on

get_streams(*args, **kwargs)¶

Deprecated since version 1.9.0.

Has been renamed to Plugin.streams(), this is an alias for backwards compatibility.

streams(stream_types=None, sorting_excludes=None)¶

Attempts to extract available streams.

Returns a dict containing the streams, where the key is the name of the stream, most commonly the quality and the value is a Stream object.

The result can contain the synonyms best and worst which points to the streams which are likely to be of highest and lowest quality respectively.

If multiple streams with the same name are found, the order of streams specified in stream_types will determine which stream gets to keep the name while the rest will be renamed to “<name>_<stream type>”.

The synonyms can be fine tuned with the sorting_excludes parameter. This can be either of these types:

A list of filter expressions in the format [operator]<value>. For example the filter “>480p” will exclude streams ranked higher than “480p” from the list used in the synonyms ranking. Valid operators are >, >=, < and <=. If no operator is specified then equality will be tested.

A function that is passed to filter() with a list of stream names as input.

Parameters:	stream_types – A list of stream types to return. sorting_excludes – Specify which streams to exclude from the best/worst synonyms.

Changed in version 1.4.2: Added priority parameter.

Changed in version 1.5.0: Renamed priority to stream_types and changed behaviour slightly.

Changed in version 1.5.0: Added sorting_excludes parameter.

Changed in version 1.6.0: sorting_excludes can now be a list of filter expressions or a function that is passed to filter().

Streams¶

All streams inherit from the Stream class.

class streamlink.stream.Stream(session)¶

open()¶

Attempts to open a connection to the stream. Returns a file-like object that can be used to read the stream data.
