streams(url, **params)¶

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

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

clear_cookies(cookie_filter=None)¶

Removes all of the saved cookies for this Plugin. To filter the cookies that are deleted specify the cookie_filter argument (see save_cookies()).

Parameters: cookie_filter (function) -- a function to filter the cookies
Returns: list of the removed cookie names

load_cookies()¶

Load any stored cookies for the plugin that have not expired.

Returns: list of the restored cookie names

classmethod priority(url)¶: Return the plugin priority for a given URL, by default it returns NORMAL priority. :return: priority level

save_cookies(cookie_filter=None, default_expires=604800)¶

Store the cookies from http in the plugin cache until they expire. The cookies can be filtered by supplying a filter method. eg. lambda c: "auth" in c.name. If no expiry date is given in the cookie then the default_expires value will be used.

Parameters

cookie_filter (function) -- a function to filter the cookies
default_expires (int) -- time (in seconds) until cookies with no expiry will expire

Returns

list of the saved cookie names

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.

class streamlink.options.Arguments(*args)¶

Provides a wrapper around a list of Argument. For example

class PluginExample(Plugin):
    arguments = PluginArguments(
        PluginArgument("username",
                       help="The username for your account.",
                       metavar="EMAIL",
                       requires=["password"]),  // requires the password too
        PluginArgument("password",
                       sensitive=True,  // should be masked in logs, etc.
                       help="The password for your account.",
                       metavar="PASSWORD")
    )

This will add the --plugin-username and --plugin-password arguments to the CLI (assuming the plugin module is plugin).

requires(name)¶

Find all the arguments required by name

Parameters: name -- name of the argument the find the dependencies
Returns: list of dependant arguments

class streamlink.options.Argument(name, required=False, requires=None, prompt=None, sensitive=False, argument_name=None, dest=None, **options)¶

Argument accepts most of the same parameters as ArgumentParser.add_argument(), except requires is a special case as in this case it is only enforced if the plugin is in use. In addition the name parameter is the name relative to the plugin eg. username, password, etc.

__init__(name, required=False, requires=None, prompt=None, sensitive=False, argument_name=None, dest=None, **options)¶

Parameters

name -- name of the argument, without -- or plugin name prefixes, eg. "password", "mux-subtitles", etc.
(bool) (sensitive) -- if the argument is required for the plugin
requires -- list of the arguments which this argument requires, eg ["password"]
prompt -- if the argument is required and not given, this prompt will show at run time
(bool) -- if the argument is sensitive (passwords, etc) and should be masked in logs and if prompted use askpass
argument_name --
option_name --
options -- arguments passed to ArgumentParser.add_argument(), excluding requires, and dest
