INPUT.CONF
==========

The input.conf file consists of a list of key bindings, for example:

| s screenshot      # take a screenshot with the s key

Each line maps a key to an input command. Keys are specified with their literal
value (upper case if combined with ``Shift``), or a name for special keys. For
example, ``a`` maps to the ``a`` key without shift, and ``A`` maps to ``a``
with shift.

A list of special keys can be obtained with

| **mpv** --input=keylist

In general, keys can be combined with ``Shift``, ``Ctrl`` and ``Alt``:

| ctrl+q quit

**mpv** can be started in input test mode, which displays key bindings and the
commands they're bound to on the OSD, instead of running the commands:

| **mpv** --input=test --demuxer=rawvideo --rawvideo=w=1280:h=720 /dev/zero

(Commands which normally close the player will not work in this mode, and you
must kill **mpv** externally to make it exit.)

General input command syntax
----------------------------

`[Shift+][Ctrl+][Alt+][Meta+]<key> [<prefixes>] <command> (<argument>)*`

Newlines always start a new binding. ``#`` starts a comment (outside of quoted
string arguments). To bind commands to the ``#`` key, ``SHARP`` can be used.

<key> is either the literal character the key produces (ASCII or unicode
character), or a symbol name.

Arguments are separated by whitespace. This applies even to string arguments.
For this reason, string arguments should be quoted with ``"``. Inside quotes,
C style escaping can be used.

Optional arguments can be skipped with ``-``.

List of input commands
----------------------

ignore
    Use this to "block" keys that should be unbound, and do nothing. Useful for
    disabling default bindings, without disabling all bindings with
    ``--input=default-bindings=no``.

seek <seconds> [relative|absolute|absolute-percent|- [default-precise|exact|keyframes]]
    Change the playback position. By default, seeks by a relative amount of
    seconds.

    The second argument sets the seek mode:

    relative (default)
        Seek relative to current position (a negative value seeks backwards).
    absolute
        Seek to a given time.
    absolute-percent
        Seek to a given percent position.

    The third argument defines how exact the seek is:

    default-precise (default)
        Follow the default behavior as set by ``--hr-seek``, which by default
        does imprecise seeks (like ``keyframes``).
    exact
        Always do exact/hr/precise seeks (slow).
    keyframes
        Always restart playback at keyframe boundaries (fast).

frame_step
    Play one frame, then pause.

set <property> "<value>"
    Set the given property to the given value.

add <property> [<value>]
    Add the given value to the property. On overflow or underflow, clamp the
    property to the maximum. If <value> is omitted, assume ``1``.

cycle <property> [up|down]
    Cycle the given property. ``up`` and ``down`` set the cycle direction. On
    overflow, set the property back to the minimum, on underflow set it to the
    maximum. If ``up`` or ``down`` is omitted, assume ``up``.

speed_mult <value>
    Multiply the ``speed`` property by the given value.

screenshot [subtitles|video|window|- [single|each-frame]]
    Take a screenshot.

    First argument:

    <subtitles> (default)
        Save the video image, in its original resolution, and with subtitles.
        Some video outputs may still include the OSD in the output under certain
        circumstances.
    <video>
        Like ``subtitles``, but typically without OSD or subtitles. The exact
        behavior depends on the selected video output.
    <window>
        Save the contents of the mpv window. Typically scaled, with OSD and
        subtitles. The exact behavior depends on the selected video output, and
        if no support is available, this will act like ``video``.

    Second argument:

    <single> (default)
        Take a single screenshot.
    <each-frame>
        Take a screenshot each frame. Issue this command again to stop taking
        screenshots.

playlist_next [weak|force]
    Go to the next entry on the playlist.

    weak (default)
        If the last file on the playlist is currently played, do nothing.
    force
        Terminate playback if there are no more files on the playlist.

playlist_prev [weak|force]
    Go to the previous entry on the playlist.

    weak (default)
        If the first file on the playlist is currently played, do nothing.
    force
        Terminate playback if the first file is being played.

loadfile "<file>" [replace|append]
    Load the given file and play it.

    Second argument:

    <replace> (default)
        Stop playback of the current file, and play the new file immediately.
    <append>
        Append the file to the playlist.

loadlist "<playlist>" [replace|append]
    Load the given playlist file (like ``--playlist``).

playlist_clear
    Clear the playlist, except the currently played file.

run "<command>"
    Run the given command with ``/bin/sh -c``. The string is expanded like in
    ``--playing-msg``.

quit [<code>]
    Exit the player using the given exit code.

sub_add "<file>"
    Load the given subtitle file. It's not selected as current subtitle after
    loading.

sub_remove [<id>]
    Remove the given subtitle track. If the ``id`` argument is missing, remove
    the current track. (Works on external subtitle files only.)

sub_reload [<id>]
    Reload the given subtitle tracks. If the ``id`` argument is missing, remove
    the current track. (Works on external subtitle files only.)

    This works by unloading and re-adding the subtitle track.

sub_step <skip>
    Change subtitle timing such, that the subtitle event after the next <skip>
    subtitle events is displayed. <skip> can be negative to step back.

osd [<level>]
    Toggle OSD level. If <level> is specified, set the OSD mode
    (see ``--osd-level`` for valid values).

print_text "<string>"
    Print text to stdout. The string can contain properties, which are expanded
    like in ``--playing-msg``.

show_text "<string>" [<duration>|- [<level>]]
    Show text on the OSD. The string can contain properties, which are expanded
    like in ``--playing-msg``. This can be used to show playback time, filename,
    and so on.

    <duration> is the time in ms to show the message. By default, it uses the
    same value as ``--osd-duration``.

    <level> is the minimum OSD level to show the text (see ``--osd-level``).

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

show_chapters
    Show a list of chapters on the OSD.

show_tracks
    Show a list of video/audio/subtitle tracks on the OSD.



Undocumented commands: tv_start_scan, tv_step_channel, tv_step_norm,
tv_step_chanlist, tv_set_channel, tv_last_channel, tv_set_freq, tv_step_freq,
tv_set_norm, dvb_set_channel, radio_step_channel, radio_set_channel,
radio_set_freq, radio_step_freq (all of these should be replaced by properties),
edl_mark, stop (questionable use), get_property (?), af_switch, af_add, af_del,
af_clr, af_cmdline, vo_cmdline (experimental).

Input command prefixes
----------------------

osd-auto (default)
    Use the default behavior for this command.
no-osd
    Do not use any OSD for this command.
osd-bar
    If possible, show a bar with this command. Seek commands will show the
    progress bar, property changing commands may show the newly set value.
osd-msg
    If possible, show an OSD message with this command. Seek command show
    the current playback time, property changing commands show the newly set
    value as text.
osd-msg-bar
    Combine osd-bar and osd-msg.



All of these are still overridden by the global ``--osd-level`` settings.

Undocumented prefixes: pausing, pausing_keep, pausing_toggle,
pausing_keep_force. (Should these be made official?)

Properties
----------

Properties are used to set mpv options during runtime, or to query arbitrary
information. They can be manipulated with the ``set``/``add``/``cycle``
commands, and retrieved with ``show_text``, or anything else that uses property
expansion. (See ``--playing-msg`` how properties are expanded.)

``W`` indicates whether the property is generally writeable. If an option
is referenced, the property should take/return exactly the same values as the
option.
