Input Commands

mpv’s command interface is shared across all control surfaces: input.conf key bindings, the JSON IPC protocol, Lua/JavaScript scripts, and the libmpv C API all use the same commands and property names.

input.conf

The input.conf file maps keys to commands. It lives at ~/.config/mpv/input.conf.

s screenshot                     # take a screenshot with the s key
LEFT seek -15                    # left arrow seeks backward 15 seconds
RIGHT seek 15                    # right arrow seeks forward 15 seconds
ctrl+q quit                      # quit with Ctrl+Q

Default bindings are defined at https://github.com/mpv-player/mpv/blob/master/etc/input.conf. List all available key names:

mpv --input-keylist

Test key bindings interactively (shows the binding on OSD instead of executing it):

mpv --input-test --force-window --idle

Syntax

[Shift+][Ctrl+][Alt+][Meta+]<key> [{<section>}] <command> [; <command> ...]

Multiple commands can be chained with ;
# begins a comment (outside quoted strings); use SHARP to bind the # key
Strings with spaces or special characters must be quoted: "...", '...', or `X...X` (custom quotes)

Multiple commands on one key

a show-text "command 1" ; show-text "command 2"

Key sequences

a-b-c show-text "pressed a, then b, then c"

Key modifiers

Modifier	Example
`Shift+`	`Shift+LEFT`
`Ctrl+`	`ctrl+q`
`Alt+`	`Alt+F4`
`Meta+`	`Meta+a`

For text keys, use the character produced by the key rather than adding Shift+. For example, @ instead of Shift+2 on a US keyboard. ASCII letters are an exception: Shift+a is interpreted as A.

`LEFT`, `RIGHT`, `UP`, `DOWN`	Arrow keys
`ENTER`, `ESC`, `TAB`, `BS`	Control keys
`SPACE`	Space bar
`KP*`	Numpad keys (e.g. `KP0`, `KP_ENTER`)

`CLOSE_WIN`	Window close button
`GAMEPAD_*`	Gamepad inputs (SDL backend)
`UNMAPPED`	Any unmapped key

`osd-auto`	Default OSD behavior for this command (default for `input.conf`)
`no-osd`	Suppress OSD for this command
`osd-bar`	Show a progress bar

`sync`	Run command synchronously if possible

# Show OSD bar when changing volume
osd-bar add volume 5
# Seek without any OSD
no-osd seek 10

Property system

Properties allow reading and writing player state at runtime. They are used by:

set, add, cycle, multiply commands
${property} expansion in show-text, print-text
Scripting APIs (mp.get_property, mp.observe_property, etc.)
IPC get_property / set_property commands

Most command-line options are also available as properties (strip the leading --). Properties marked (RW) can be written; others are read-only.

Command reference

Playback control

seek <target> [<flags>]

Change playback position.Flags (combine with +):

In scripts:

mp.commandv("seek", "30", "relative")
mp.commandv("seek", "50", "absolute-percent")

revert-seek [<flags>]

Undo the most recent seek. Call again to undo the revert. Works within a single file.Flags: mark (mark current position for revert), mark-permanent (always revert to this position until changed).

frame-step [<frames>] [<flags>]

Advance or step back by frames. Default is 1 frame. Flags: play (default — play then pause), seek (precise seek), mute (like play but muted). Does not work with audio-only playback.

frame-back-step

Step back exactly one frame. Equivalent to frame-step -1 seek. Does not work with audio-only playback.

stop [<flags>]

ctrl+m set mute yes
f       set fullscreen yes

mp.commandv("set", "volume", "80")

add <name> [<value>]

OSD and text

show-text <text> [<duration>|-1 [<level>]]

Show text on the OSD. Properties are expanded (e.g. ${playback-time}). no-osd prefix has no effect on this command.duration is in milliseconds (default: --osd-duration). level is the minimum OSD level required to show the text.

i show-text "${filename} (${playback-time})"

mp.commandv("show-text", "Hello from Lua!", "3000")

show-progress

Show the progress bar, elapsed time, and total duration on the OSD.

print-text <text>

Print text to stdout. Properties are expanded.

Scripting and messaging

script-message [<arg1> [<arg2> ...]]

Send a message to all scripts. Arguments are arbitrary strings. All scripts receive the message.

x script-message my-event arg1 arg2

In Lua, register a handler with mp.register_script_message("my-event", fn).

script-message-to <target> [<arg1> ...]

Like script-message, but send only to the named client. The target name is the script’s internal name (as returned by mp.get_script_name()).

x script-message-to my_script my-event arg1

script-binding <name> [<arg>]

Invoke a key binding registered by a script via mp.add_key_binding. Useful for remapping script bindings.

y script-binding my_script/some-action

load-script <filename>

Load a script at runtime, similar to --script. Returns a client_id field in the result.

Execution

run <command> [<arg1> ...]

Run an external program. Unlike the shell, arguments are passed directly without shell interpretation. The program is detached — mpv continues immediately without waiting.

# Write the playing title to a file
ctrl+t run "/bin/sh" "-c" "echo ${media-title} > /tmp/playing"

Use subprocess when you need to wait for the result or capture output.

subprocess

Run an external program with full control. Uses named arguments.Key parameters:

Parameter	Type	Description
`args`	string array	Command and arguments
`playback_only`	bool	Kill process when playback ends (default: true)
`capture_stdout`	bool	Capture stdout (default: false)
`capture_stderr`	bool	Capture stderr (default: false)
`capture_size`	integer	Max bytes to capture per stream (default: 64 MB)
`stdin_data`	string	Data to feed to stdin
`env`	string array	Environment variables (`NAME=VALUE` format)
`detach`	bool	Run detached (default: false)

local r = mp.command_native({
    name = "subprocess",
    playback_only = false,
    capture_stdout = true,
    args = {"cat", "/proc/cpuinfo"},
})
if r.status == 0 then
    mp.msg.info(r.stdout)
end

The result includes status, stdout, stderr, error_string, and killed_by_us.

Quit

Command	Description
`quit [<code>]`	Exit mpv with optional exit code
`quit-watch-later [<code>]`	Exit and save playback position for resuming

q quit

Property expansion

Properties can be embedded in string arguments with ${property-name}. Use ${=property-name} for the raw (unformatted) value.

i show-text "${media-title} [${time-pos} / ${duration}]"

Disable expansion with the raw prefix or $> within the string:

x show-text "literal: $>no ${expansion} here"

Property expansion happens after argument parsing. It applies by default in input.conf commands but not in scripting API calls (use expand-properties prefix to enable it there).

Events

Events are notifications sent from the player core to scripts and IPC clients. See also: Lua scripting events.

start-file

Before a file starts loading. Fields: playlist_entry_id.

file-loaded

After a file is loaded and playback begins.

end-file

After a file is unloaded. Fields: reason (eof, stop, quit, error, redirect), playlist_entry_id.

seek

On any seek (including internal seeks).

video-reconfig

Video output or filter reconfigured.

audio-reconfig

Audio output or filter reconfigured.

client-message

A script-message was received. Fields: args (string array).

Hooks

Hooks block the player until all registered handlers call cont() (or return if defer() was not called). They provide synchronous control at specific points.

Hook	Timing
`on_load`	Before opening a file
`on_load_fail`	After file open fails
`on_preloaded`	After open, before track selection
`on_loaded`	After track selection, before playback
`on_unload`	Before closing a file
`on_before_start_file`	Before `start-file` event
`on_after_end_file`	After `end-file` event
