Command-Line Interface

Tutorial

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 (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:

Configuration file

Writing the command-line options every time is inconvenient, that's why Streamlink is capable of reading options from a configuration file instead.

Streamlink will look for config files in different locations depending on your platform:

Platform

Location

Linux, BSD

  • ${XDG_CONFIG_HOME:-${HOME}/.config}/streamlink/config

Deprecated:

  • ${HOME}/.streamlinkrc

macOS

  • ${HOME}/Library/Application Support/streamlink/config

Deprecated:

  • ${XDG_CONFIG_HOME:-${HOME}/.config}/streamlink/config

  • ${HOME}/.streamlinkrc

Windows

  • %APPDATA%\streamlink\config

Deprecated:

  • %APPDATA%\streamlink\streamlinkrc

You can also specify the location yourself using the --config option.

Warning

On Windows, there is a default config created by the installer, but on any other platform you must create the file yourself.

Syntax

The config file is a simple text file and should contain one command-line option (omitting the dashes) per line in the format:

option=value

or for an option without value:

option

Note

Any quotes used will be part of the value, so only use them when the value needs them, e.g. when specifying a player with a path which contains spaces.

Example

# Player options
player=mpv --cache 2048
player-no-close

Note

Full player paths are supported via configuration file options such as player="C:\mpv-x86_64\mpv"

Plugin specific configuration file

You may want to use specific options for some plugins only. This can be accomplished by placing those settings inside a plugin specific config file. Options inside these config files will override the main config file when a URL matching the plugin is used.

Streamlink expects this config to be named like the main config but with .<plugin name> attached to the end.

Examples

Platform

Location

Linux, BSD

  • ${XDG_CONFIG_HOME:-${HOME}/.config}/streamlink/config.pluginname

Deprecated:

  • ${HOME}/.streamlinkrc.pluginname

macOS

  • ${HOME}/Library/Application Support/streamlink/config.pluginname

Deprecated:

  • ${XDG_CONFIG_HOME:-${HOME}/.config}/streamlink/config.pluginname

  • ${HOME}/.streamlinkrc.pluginname

Windows

  • %APPDATA%\streamlink\config.pluginname

Deprecated:

  • %APPDATA%\streamlink\streamlinkrc.pluginname

Have a look at the list of plugins, or check the --plugins option to see the name of each built-in plugin.

Sideloading plugins

Streamlink will attempt to load standalone plugins from these directories:

Platform

Location

Linux, BSD

  • ${XDG_DATA_HOME:-${HOME}/.local/share}/streamlink/plugins

Deprecated:

  • ${XDG_CONFIG_HOME:-${HOME}/.config}/streamlink/plugins

macOS

  • ${HOME}/Library/Application Support/streamlink/plugins

Deprecated:

  • ${XDG_CONFIG_HOME:-${HOME}/.config}/streamlink/plugins

Windows

  • %APPDATA%\streamlink\plugins

Note

If a plugin is added with the same name as a built-in plugin, then the added plugin will take precedence. This is useful if you want to upgrade plugins independently of the Streamlink version.

Warning

If one of the sideloaded plugins fails to load, eg. due to a SyntaxError being raised by the parser, this exception will not get caught by Streamlink and the execution will stop, even if the input stream URL does not match the faulty plugin.

Plugin specific usage

Authenticating with Crunchyroll

Crunchyroll requires authenticating with a premium account to access some of their content. To do so, the plugin provides a couple of options to input your information, --crunchyroll-username and --crunchyroll-password.

You can login like this:

$ streamlink --crunchyroll-username=xxxx --crunchyroll-password=xxx https://crunchyroll.com/a-crunchyroll-episode-link

Note

If you omit the password, streamlink will ask for it.

Once logged in, the plugin makes sure to save the session credentials to avoid asking your username and password again.

Nevertheless, these credentials are valid for a limited amount of time, so it might be a good idea to save your username and password in your configuration file anyway.

Warning

The API this plugin uses isn't supposed to be available on desktop computers. The plugin tries to blend in as a valid device using custom headers and following the API's usual flow (e.g. reusing credentials), but this does not assure that your account will be safe from being spotted for unusual behavior.

HTTP proxy with Crunchyroll

To be able to stream region locked content, you can use Streamlink's proxy options, which are described in the Proxy Support section.

When doing this, it's possible that access to the stream will still be denied; this can happen because the session and credentials used by the plugin were obtained while being logged from your own region, and the server still assumes you're in that region.

For cases like this, the plugin provides the --crunchyroll-purge-credentials option, which removes your saved session and credentials and tries to log in again using your username and password.

Authenticating with FunimationNow

Like Crunchyroll, the FunimationNow plugin requires authenticating with a premium account to access some content: --funimation-email, --funimation-password. In addition, this plugin requires the incap_ses cookie to be sent with each HTTP request (see issue #2088). This unique session cookie can be found in your browser and sent via the --http-cookie option.

$ streamlink --funimation-email='xxx' --funimation-password='xxx' --http-cookie 'incap_ses_xxx=xxxx=' https://funimation.com/shows/show/an-episode-link

Note

There are multiple ways to retrieve the required cookie. For more information on browser cookies, please consult the following:

Playing built-in streaming protocols directly

There are many types of streaming protocols used by services today and Streamlink supports most of them. It's possible to tell Streamlink to access a streaming protocol directly instead of relying on a plugin to extract the streams from a URL for you.

A protocol can be accessed directly by specifying it in the URL format:

protocol://path [key=value]

Accessing a stream that requires extra parameters to be passed along (e.g. RTMP):

$ streamlink "rtmp://streaming.server.net/playpath live=1 swfVfy=http://server.net/flashplayer.swf"

When passing parameters to the built-in stream plugins, the values will either be treated as plain strings, as is the case in the example above for swfVry, or they will be interpreted as Python literals. For example, you can pass a Python dict or Python list as one of the parameters.

$ streamlink "rtmp://streaming.server.net/playpath conn=['B:1', 'S:authMe', 'O:1', 'NN:code:1.23', 'NS:flag:ok', 'O:0']"
$ streamlink "hls://streaming.server.net/playpath params={'token': 'magicToken'}"

In the examples above, conn will be passed as a Python list:

['B:1', 'S:authMe', 'O:1', 'NN:code:1.23', 'NS:flag:ok', 'O:0']

and params will be passed as a Python dict:

{'token': 'magicToken'}

Most streaming protocols only require you to pass a simple URL. This is an Adobe HDS stream:

$ streamlink hds://streaming.server.net/playpath/manifest.f4m

Supported streaming protocols

Adobe HTTP Dynamic Streaming

hds://

Progressive HTTP, HTTPS, etc

httpstream:// 1

supports local files using the file:// protocol

2

Dynamic Adaptive Streaming over HTTP

Proxy Support

You can use the --http-proxy or --https-proxy options to change the proxy server that Streamlink will use for HTTP and HTTPS requests respectively. For convenience reasons, --http-proxy will automatically set the value of --https-proxy as well, if it has not been set by the user.

Both HTTP and SOCKS proxies are supported, as well as authentication in each of them.

Note

When using a SOCKS proxy, the socks4 and socks5 schemes mean that DNS lookups are done locally, rather than on the proxy server. To have the proxy server perform the DNS lookups, the socks4a and socks5h schemes should be used instead.

$ streamlink --http-proxy "http://user:pass@10.10.1.10:3128/" --https-proxy "socks5://10.10.1.10:1242"
$ streamlink --http-proxy "socks4a://10.10.1.10:1235" --https-proxy "socks5h://10.10.1.10:1234"

Command-line usage

$ streamlink [OPTIONS] <URL> [STREAM]

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-handle-url URL

Check if Streamlink has a plugin that can handle the specified URL.

Returns status code 1 for false and 0 for true.

Useful for external scripting.

--can-handle-url-no-redirect URL

Same as --can-handle-url but without following redirects when looking up the URL.

--config FILENAME

Load options from this config file.

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
-Q
--quiet

Hide all log output.

Alias for "--loglevel none".

-j
--json

Output JSON representations instead of the normal text output.

Useful for external scripting.

--auto-version-check {yes,true,1,on,no,false,0,off}

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.

Default is: system locale.

--interface INTERFACE

Set the network interface.

-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

  • rtmp

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

This option allows you to supply a title to be displayed in the title bar of the window that the video player is launched in.

This 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 }}.

This option is only supported for the following players: mpv, potplayer, vlc.

VLC specific information:

VLC has certain codes you can use inside your title. These are accessible inside --title by using a backslash before the dollar sign VLC uses to denote a format character.

e.g. to put the current date in your VLC window title, the string "$A" could be inserted inside your --title string.

A full list of the format codes VLC uses is available here: https://wiki.videolan.org/Documentation:Format_String/

mpv specific information:

mpv has certain codes you can use inside your title. These are accessible inside --title by using a backslash before the dollar sign mpv uses to denote a format character.

e.g. to put the current version of mpv running inside your mpv window title, the string "${{mpv-version}}" could be inserted inside your --title string.

A full list of the format codes mpv uses is available here: https://mpv.io/manual/stable/#property-list

Formatting variables available to use in --title:

{title}

If available, this is the title of the stream. Otherwise, it is the string "Unknown Title"

{author}

If available, this is the author of the stream. Otherwise, it is the string "Unknown Author"

{category}

If available, this is the category the stream has been placed into.

  • For Twitch, this is the game being played

  • For YouTube, it's the category e.g. Gaming, Sports, Music...

Otherwise, it is the string "No Category"

{game}

This is just a synonym for {category} which may make more sense for gaming oriented platforms. "Game being played" is a way to categorize the stream, so it doesn't need its own separate handling.

{url}

URL of the stream.

{time}

The current timestamp, which can optionally be formatted via {time:format}. This format parameter string is passed to Python's datetime.strftime() method, so all usual time directives are available. The default format is "%Y-%m-%d_%H-%M-%S".

Examples:

streamlink -p vlc --title "{title} -!- {author} -!- {category} \$A" <url> [stream]
streamlink -p mpv --title "{title} -- {author} -- {category} -- (\${{mpv-version}})" <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.

The formatting variables available for the --title option may be used. Unsupported characters in substituted variables will be replaced with an underscore.

-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.

The formatting variables available for the --title option may be used. Unsupported characters in substituted variables will be replaced with an underscore.

-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.

The formatting variables available for the --title option may be used. Unsupported characters in substituted variables will be replaced with an underscore.

--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: "rtmp,hls,hds,http,akamaihd,*".

--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 (such as HDS) 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, HDS, 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, HDS, 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, HDS, 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, HDS, HLS, HTTP, RTMP, 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, pluzz, rtve, svtplay, vimeo

HDS options

--hds-live-edge SECONDS

The time live HDS streams will start from the edge of the stream.

Default is: 10.0.

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-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.

RTMP options

--rtmp-rtmpdump FILENAME

RTMPDump is used to access RTMP streams. You can specify the location of the rtmpdump executable if it is not in your PATH.

Example: "/usr/local/bin/rtmpdump"

--rtmp-proxy PROXY

A SOCKS proxy that RTMP streams will use.

Example: 127.0.0.1:9050

Subprocess options

--subprocess-cmdline

Print the command-line used internally to play the stream.

This is only available on RTMP streams.

--subprocess-errorlog

Log possible errors from internal subprocesses to a temporary file. The file will be saved in your systems temporary directory.

Useful when debugging rtmpdump related issues.

--subprocess-errorlog-path PATH

Log the subprocess errorlog to a specific file rather than a temporary file. Takes precedence over subprocess-errorlog.

Useful when debugging rtmpdump related issues.

FFmpeg options

--ffmpeg-ffmpeg FILENAME

FFMPEG is used to access or mux separate video and audio streams. You can specify the location of the ffmpeg executable if it is not in your PATH.

Example: "/usr/local/bin/ffmpeg"

--ffmpeg-verbose

Write the console output from ffmpeg to the console.

--ffmpeg-verbose-path PATH

Path to write the output from the ffmpeg console.

--ffmpeg-fout OUTFORMAT

--twitch-low-latency

Enables low latency streaming by prefetching HLS segments. Sets --hls-live-edge to 2, if it is higher. Reducing it 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 streams can cause buffering issues with this option enabled due to the reduced --hls-live-edge value.
