POSITIONAL ARGUMENTS
URL A URL to attempt to extract streams from.
Usually, the protocol of http(s) URLs can be omitted ("https://"), depending on the implementation
of the plugin being used.
Alternatively, the URL can also be specified by using the --url option.
STREAM Stream to play.
Use best or worst for selecting the highest or lowest available quality.
Fallback streams can be specified by using a comma-separated list:
"720p,480p,best"
If no stream is specified and --default-stream is not used, then a list of available streams will
be printed.
GENERAL OPTIONS
-h
--help Show this help message and exit.
-V
--version
Show version number and exit.
--plugins
Print a list of all currently installed plugins.
--plugin-dirs DIRECTORY
Attempts to load plugins from these directories.
Multiple directories can be used by separating them with a comma.

Can be repeated to load multiple files, in which case the options are merged on top of each other
where the last config has highest priority.
-l LEVEL
--loglevel LEVEL
Set the log message threshold.
Valid levels are: none, error, warning, info, debug, trace
--logfile FILE
Append log output to FILE instead of writing to stdout/stderr.
User prompts and download progress won't be written to FILE.
A value of - will set the file name to an ISO8601-like string and will choose the following
default log directories.
Windows:
%TEMP%\streamlink\logs
macOS:
${HOME}/Library/Logs/streamlink
Linux/BSD:
${XDG_STATE_HOME:-${HOME}/.local/state}/streamlink/logs

Enable or disable the automatic check for a new version of Streamlink.
Default is: "no".
--version-check
Runs a version check and exits.
--locale LOCALE
The preferred locale setting, for selecting the preferred subtitle and audio language.
The locale is formatted as [language_code]_[country_code], eg. en_US or es_ES.

-4
--ipv4 Resolve address names to IPv4 only. This option overrides -6.
-6
--ipv6 Resolve address names to IPv6 only. This option overrides -4.
PLAYER OPTIONS
-p COMMAND
--player COMMAND
Player to feed stream data to. By default, VLC will be used if it can be found in its default
location.
This is a shell-like syntax to support using a specific player:
streamlink --player=vlc <url> [stream]
Absolute or relative paths can also be passed via this option in the event the player's executable
can not be resolved:
streamlink --player=/path/to/vlc <url> [stream]
streamlink --player=./vlc-player/vlc <url> [stream]
To use a player that is located in a path with spaces you must quote the parameter or its value:
streamlink "--player=/path/with spaces/vlc" <url> [stream]
streamlink --player "C:\path\with spaces\mpc-hc64.exe" <url> [stream]
Options may also be passed to the player. For example:
streamlink --player "vlc --file-caching=5000" <url> [stream]
As an alternative to this, see the --player-args parameter, which does not log any custom player
arguments.
-a ARGUMENTS
--player-args ARGUMENTS
This option allows you to customize the default arguments which are put together with the value of
--player to create a command to execute.
It's usually enough to only use --player instead of this unless you need to add arguments after
the player's input argument or if you don't want any of the player arguments to be logged.
The value can contain formatting variables surrounded by curly braces, { and }. If you need to
include a brace character, it can be escaped by doubling, e.g. {{ and }}.
Formatting variables available:
{playerinput}
This is the input that the player will use. For standard input (stdin), it is -, but it can
also be a URL, depending on the options used.
{filename}
The old fallback variable name with the same functionality.
Example:
streamlink -p vlc -a "--play-and-exit {playerinput}" <url> [stream]
NOTE:
When neither of the variables are found, {playerinput} will be appended to the whole parameter
value, to ensure that the player always receives an input argument.
-v
--verbose-player
Allow the player to display its console output.
-n
--player-fifo
--fifo Make the player read the stream through a named pipe instead of the stdin pipe.
--player-http
Make the player read the stream through HTTP instead of the stdin pipe.
--player-continuous-http
Make the player read the stream through HTTP, but unlike --player-http it will continuously try to
open the stream if the player requests it.
This makes it possible to handle stream disconnects if your player is capable of reconnecting to a
HTTP stream. This is usually done by setting your player to a "repeat mode".
--player-external-http
Serve stream data through HTTP without running any player. This is useful to allow external
devices like smartphones or streaming boxes to watch streams they wouldn't be able to otherwise.
Behavior will be similar to the continuous HTTP option, but no player program will be started, and
the server will listen on all available connections instead of just in the local (loopback)
interface.
The URLs that can be used to access the stream will be printed to the console, and the server can
be interrupted using CTRL-C.
--player-external-http-port PORT
A fixed port to use for the external HTTP server if that mode is enabled. Omit or set to 0 to use
a random high ( >1024) port.
--player-passthrough TYPES
A comma-delimited list of stream types to pass to the player as a URL to let it handle the
transport of the stream instead.
Stream types that can be converted into a playable URL are:
• hls
• http
Make sure your player can handle the stream type when using this.
--player-no-close
By default Streamlink will close the player when the stream ends. This is to avoid "dead" GUI
players lingering after a stream ends.
It does however have the side-effect of sometimes closing a player before it has played back all
of its cached data.
This option will instead let the player decide when to exit.
-t TITLE
--title TITLE
Change the title of the video player's window.
Please see the "Metadata variables" section of Streamlink's CLI documentation for all available
metadata variables.
This option is only supported for the following players: mpv, potplayer, vlc
VLC specific information:
VLC does support special formatting variables on its own:
https://wiki.videolan.org/Documentation:Format_String/
These variables are accessible in the --title option by adding a backslash in front of the
dollar sign which VLC uses as its formatting character.
For example, to put the current date in your VLC window title, the string "\$A" could be
inserted inside the --title string.
Example:
streamlink -p mpv --title "{author} - {category} - {title}" <URL> [STREAM]
FILE OUTPUT OPTIONS
-o FILENAME
--output FILENAME
Write stream data to FILENAME instead of playing it.
You will be prompted if the file already exists.
Please see the "Metadata variables" section of Streamlink's CLI documentation for all available
metadata variables.
Unsupported characters in substituted variables will be replaced with an underscore.
Example:
streamlink --output "~/recordings/{author}/{category}/{id}-{time:%Y%m%d%H%M%S}.ts" <URL> [STREAM]
-f
--force
When using -o or -r, always write to file even if it already exists.
--force-progress
When using -o or -r, show the download progress bar even if there is no terminal.
-O
--stdout
Write stream data to stdout instead of playing it.
-r FILENAME
--record FILENAME
Open the stream in the player, while at the same time writing it to FILENAME.
You will be prompted if the file already exists.
Please see the "Metadata variables" section of Streamlink's CLI documentation for all available
metadata variables.
Unsupported characters in substituted variables will be replaced with an underscore.
Example:
streamlink --record "~/recordings/{author}/{category}/{id}-{time:%Y%m%d%H%M%S}.ts" <URL> [STREAM]
-R FILENAME
--record-and-pipe FILENAME
Write stream data to stdout, while at the same time writing it to FILENAME.
You will be prompted if the file already exists.
Please see the "Metadata variables" section of Streamlink's CLI documentation for all available
metadata variables.
Unsupported characters in substituted variables will be replaced with an underscore.
Example:
streamlink --record-and-pipe "~/recordings/{author}/{category}/{id}-{time:%Y%m%d%H%M%S}.ts" <URL> [STREAM]
--fs-safe-rules
The rules used to make formatting variables filesystem-safe are chosen automatically according to
the type of system in use. This overrides the automatic detection.
Intended for use when Streamlink is running on a UNIX-like OS but writing to Windows filesystems
such as NTFS; USB devices using VFAT or exFAT; CIFS shares that are enforcing Windows filename
limitations, etc.
These characters are replaced with an underscore for the rules in use:
POSIX : \x00-\x1F /
Windows: \x00-\x1F \x7F " * / : < > ? \ |
STREAM OPTIONS
--url URL
A URL to attempt to extract streams from.
Usually, the protocol of http(s) URLs can be omitted (https://), depending on the implementation
of the plugin being used.
This is an alternative to setting the URL using a positional argument and can be useful if set in
a config file.
--default-stream STREAM
Stream to play.
Use best or worst for selecting the highest or lowest available quality.
Fallback streams can be specified by using a comma-separated list:
"720p,480p,best"
This is an alternative to setting the stream using a positional argument and can be useful if set
in a config file.
--stream-url
If possible, translate the resolved stream to a URL and print it.
--retry-streams DELAY
Retry fetching the list of available streams until streams are found while waiting DELAY second(s)
between each attempt. If unset, only one attempt will be made to fetch the list of streams
available.
The number of fetch retry attempts can be capped with --retry-max.
--retry-max COUNT
When using --retry-streams, stop retrying the fetch after COUNT retry attempt(s). Fetch will retry
infinitely if COUNT is zero or unset.
If --retry-max is set without setting --retry-streams, the delay between retries will default to 1
second.
--retry-open ATTEMPTS
After a successful fetch, try ATTEMPTS time(s) to open the stream until giving up.
Default is: 1.
--stream-types TYPES
--stream-priority TYPES
A comma-delimited list of stream types to allow.
The order will be used to separate streams when there are multiple streams with the same name but
different stream types. Any stream type not listed will be omitted from the available streams
list. A * can be used as a wildcard to match any other type of stream, eg. muxed-stream.
Default is: "hls,http,*".
--stream-sorting-excludes STREAMS
Fine tune the best and worst stream name synonyms by excluding unwanted streams.
If all of the available streams get excluded, best and worst will become inaccessible and new
special stream synonyms best-unfiltered and worst-unfiltered can be used as a fallback selection
method.
Uses a filter expression in the format:
[operator]<value>
Valid operators are >, >=, < and <=. If no operator is specified then equality is tested.
For example this will exclude streams ranked higher than "480p":
">480p"
Multiple filters can be used by separating each expression with a comma.
For example this will exclude streams from two quality types:
">480p,>medium"
STREAM TRANSPORT OPTIONS
--ringbuffer-size SIZE
The maximum size of the ringbuffer. Mega- or kilobytes can be specified via the M or K suffix
respectively.
The ringbuffer is used as a temporary storage between the stream and the player. This allows
Streamlink to download the stream faster than the player which reads the data from the ringbuffer.
The smaller the size of the ringbuffer, the higher the chance of the player buffering if the
download speed decreases, and the higher the size, the more data can be use as a storage to
recover from volatile download speeds.
Most players have their own additional cache and will read the ringbuffer's content as soon as
data is available. If the player stops reading data while playback is paused, Streamlink will
continue to download the stream in the background as long as the ringbuffer doesn't get full.
Default is: "16M".
NOTE:
A smaller size is recommended on lower end systems (such as Raspberry Pi) when playing stream
types that require some extra processing to avoid unnecessary background processing.
--stream-segment-attempts ATTEMPTS
How many attempts should be done to download each segment before giving up.
This applies to all different kinds of segmented stream types, such as DASH, HLS, etc.
Default is: 3.
--stream-segment-threads THREADS
The size of the thread pool used to download segments. Minimum value is 1 and maximum is 10.
This applies to all different kinds of segmented stream types, such as DASH, HLS, etc.
Default is: 1.
--stream-segment-timeout TIMEOUT
Segment connect and read timeout.
This applies to all different kinds of segmented stream types, such as DASH, HLS, etc.
Default is: 10.0.
--stream-timeout TIMEOUT
Timeout for reading data from streams.
This applies to all different kinds of stream types, such as DASH, HLS, HTTP, etc.
Default is: 60.0.
--mux-subtitles
Automatically mux available subtitles into the output stream.
Needs to be supported by the used plugin.
Supported plugins: funimationnow, rtve, svtplay, vimeo
HLS options
--hls-live-edge SEGMENTS
Number of segments from the live stream's current live position to begin streaming. The size or
length of each segment is determined by the streaming provider.
Lower values will decrease the latency, but will also increase the chance of buffering, as there
is less time for Streamlink to download segments and write their data to the output buffer. The
number of parallel segment downloads can be set with --stream-segment-threads and the HLS playlist
reload time to fetch and queue new segments can be overridden with --hls-playlist-reload-time.
Default is: 3.
NOTE:
During live playback, the caching/buffering settings of the used player will add additional
latency. To adjust this, please refer to the player's own documentation for the required
configuration. Player parameters can be set via --player-args.
--hls-segment-stream-data
Immediately write segment data into output buffer while downloading.
--hls-playlist-reload-attempts ATTEMPTS
How many attempts should be done to reload the HLS playlist before giving up.
Default is: 3.
--hls-playlist-reload-time TIME
Set a custom HLS playlist reload time value, either in seconds or by using one of the following
keywords:
segment: The duration of the last segment in the current playlist
live-edge: The sum of segment durations of the live edge value minus one
default: The playlist's target duration metadata
Default is: default.
--hls-segment-ignore-names NAMES
A comma-delimited list of segment names that will get filtered out.
Example: --hls-segment-ignore-names 000,001,002
This will ignore every segment that ends with 000.ts, 001.ts and 002.ts
Default is: None.
--hls-segment-key-uri URI
Override the segment encryption key URIs for encrypted streams.
The value can be templated using the following variables, which will be replaced with their
respective part from the source segment URI:
{url} {scheme} {netloc} {path} {query}
Examples:
--hls-segment-key-uri "https://example.com/hls/encryption_key"
--hls-segment-key-uri "{scheme}://1.2.3.4{path}{query}"
--hls-segment-key-uri "{scheme}://{netloc}/custom/path/to/key"
Default is: None.
--hls-audio-select CODE
Selects a specific audio source or sources, by language code or name, when multiple audio sources
are available. Can be * to download all audio sources.
Examples:
--hls-audio-select "English,German"
--hls-audio-select "en,de"
--hls-audio-select "*"
NOTE:
This is only useful in special circumstances where the regular locale option fails, such as
when multiple sources of the same language exists.
--hls-start-offset [HH:]MM:SS
Amount of time to skip from the beginning of the stream. For live streams, this is a negative
offset from the end of the stream (rewind).
Default is: 00:00:00.
--hls-duration [HH:]MM:SS
Limit the playback duration, useful for watching segments of a stream. The actual duration may be
slightly longer, as it is rounded to the nearest HLS segment.
Default is: unlimited.
--hls-live-restart
Skip to the beginning of a live stream, or as far back as possible.

--twitch-low-latency
Enables low latency streaming by prefetching HLS segments. Sets --hls-segment-stream-data to true
and --hls-live-edge to 2, if it is higher. Reducing --hls-live-edge to 1 will result in the
lowest latency possible, but will most likely cause buffering.
In order to achieve true low latency streaming during playback, the player's caching/buffering
settings will need to be adjusted and reduced to a value as low as possible, but still high enough
to not cause any buffering. This depends on the stream's bitrate and the quality of the
connection to Twitch's servers. Please refer to the player's own documentation for the required
configuration. Player parameters can be set via --player-args.
NOTE:
Low latency streams have to be enabled by the broadcasters on Twitch themselves. Regular
