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 executing the commands::
|
|
|
|
mpv --input-test --demuxer=rawvideo --demuxer-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> [{<section>}] [<prefixes>] <command> (<argument>)* [; <command>]``
|
|
|
|
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.
|
|
|
|
``<section>`` (braced with ``{`` and ``}``) is the input section for this
|
|
command.
|
|
|
|
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 ``-``.
|
|
|
|
You can bind multiple commands to one key. For example:
|
|
|
|
| a show_text "command 1" ; show_text "command 2"
|
|
|
|
Note that some magic is disabled for keys: seek commands inside lists are not
|
|
coalesced (seeking will appear slower), and no check is done for abort commands
|
|
(so these commands can't be used to abort playback if the network cache is
|
|
stuck).
|
|
|
|
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
|
|
``--no-input-default-bindings``.
|
|
|
|
``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.
|
|
|
|
``frame_back_step``
|
|
Go back by one frame, then pause. Note that this can be very slow (it tries
|
|
to be precise, not fast), and sometimes fails to behave as expected. How
|
|
well this works depends on whether precise seeking works correctly (e.g.
|
|
see the ``--hr-seek-demuxer-offset`` option). Video filters or other video
|
|
postprocessing that modifies timing of frames (e.g. deinterlacing) should
|
|
usually work, but might make backstepping silently behave incorrectly in
|
|
corner cases.
|
|
|
|
This does not work with audio-only playback.
|
|
|
|
``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.
|
|
|
|
``screenshot_to_file "<filename>" [subtitles|video|window]``
|
|
Take a screenshot and save it to a given file. The format of the file will
|
|
be guessed by the extension (and ``--screenshot-format`` is ignored - the
|
|
behavior when the extension is missing or unknown is arbitrary).
|
|
|
|
The second argument is like the first argument to ``screenshot``.
|
|
|
|
This command tries to never overwrite files. If the file already exists,
|
|
it fails.
|
|
|
|
Like all input command parameters, the filename is subject to property
|
|
expansion as described in `Property Expansion`_.
|
|
|
|
``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.
|
|
|
|
``playlist_remove <index>``
|
|
Remove the playlist entry at the given index. Index values start counting
|
|
with 0. You cannot remove the entry for the currently played file.
|
|
|
|
``playlist_move <index1> <index2>``
|
|
Move the playlist entry at index1, so that it takes the place of the
|
|
entry index2. (Paradoxically, the moved playlist entry will not have
|
|
the index value index2 after moving if index1 was lower than index2,
|
|
because index2 refers to the target entry, not the index the entry
|
|
will have after moving.)
|
|
|
|
``run "<command>"``
|
|
Run the given command with ``/bin/sh -c``. The string is expanded like in
|
|
`Property Expansion`_.
|
|
|
|
``quit [<code>]``
|
|
Exit the player using the given exit code.
|
|
|
|
``quit_watch_later``
|
|
Exit player, and store current playback position. Playing that file later
|
|
will seek to the previous position on start.
|
|
|
|
``sub_add "<file>"``
|
|
Load the given subtitle file. It is 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
|
|
backwards.
|
|
|
|
``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 (see
|
|
`Property Expansion`_).
|
|
|
|
``show_text "<string>" [<duration>|- [<level>]]``
|
|
Show text on the OSD. The string can contain properties, which are expanded
|
|
as described in `Property Expansion`_. This can be used to show playback
|
|
time, filename, and so on.
|
|
|
|
<duration>
|
|
The time in ms to show the message for. By default, it uses the same
|
|
value as ``--osd-duration``.
|
|
|
|
<level>
|
|
The minimum OSD level to show the text at (see ``--osd-level``).
|
|
|
|
``show_progress``
|
|
Show the progress bar, the elapsed time and the total duration of the file
|
|
on the OSD.
|
|
|
|
Input Commands that are Possibly Subject to Change
|
|
--------------------------------------------------
|
|
|
|
``af set|add|toggle|del|clr "filter1=params,filter2,..."``
|
|
Change audio filter chain. See ``vf`` command.
|
|
|
|
``vf set|add|toggle|del|clr "filter1=params,filter2,..."``
|
|
Change video filter chain.
|
|
|
|
The first argument decides what happens:
|
|
|
|
set
|
|
Overwrite the previous filter chain with the new one.
|
|
|
|
add
|
|
Append the new filter chain to the previous one.
|
|
|
|
toggle
|
|
Check if the given filter (with the exact parameters) is already
|
|
in the video chain. If yes, remove the filter. If no, add the filter.
|
|
(If several filters are passed to the command, this is done for
|
|
each filter.)
|
|
|
|
del
|
|
Remove the given filters from the video chain. Unlike in the other
|
|
cases, the second parameter is a comma separated list of filter names
|
|
or integer indexes. ``0`` would denote the first filter. Negative
|
|
indexes start from the last filter, and ``-1`` denotes the last
|
|
filter.
|
|
|
|
clr
|
|
Remove all filters. Note that like the other sub-commands, this does
|
|
not control automatically inserted filters.
|
|
|
|
You can assign labels to filter by prefixing them with ``@name:`` (where
|
|
``name`` is a user-chosen arbitrary identifier). Labels can be used to
|
|
refer to filters by name in all of the filter chain modification commands.
|
|
For ``add``, using an already used label will replace the existing filter.
|
|
|
|
The ``vf`` command shows the list of requested filters on the OSD after
|
|
changing the filter chain. This is roughly equivalent to
|
|
``show_text ${vf}``. Note that auto-inserted filters for format conversion
|
|
are not shown on the list, only what was requested by the user.
|
|
|
|
.. admonition:: Example for input.conf
|
|
|
|
- ``a vf set flip`` turn video upside-down on the ``a`` key
|
|
- ``b vf set ""`` remove all video filters on ``b``
|
|
- ``c vf toggle lavfi=gradfun`` toggle debanding on ``c``
|
|
|
|
``enable_section "<section>" [default|exclusive]``
|
|
Enable all key bindings in the named input section.
|
|
|
|
The enabled input sections form a stack. Bindings in sections on the top of
|
|
the stack are preferred to lower sections. This command puts the section
|
|
on top of the stack. If the section was already on the stack, it is
|
|
implicitly removed beforehand. (A section cannot be on the stack more than
|
|
once.)
|
|
|
|
If ``exclusive`` is specified as second argument, all sections below the
|
|
newly enabled section are disabled. They will be re-enabled as soon as
|
|
all exclusive sections above them are removed.
|
|
|
|
``disable_section "<section>"``
|
|
Disable the named input section. Undoes ``enable_section``.
|
|
|
|
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), ``stop`` (questionable use), ``get_property``
|
|
(?), ``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.
|
|
``raw``
|
|
Do not expand properties in string arguments. (Like ``"${property-name}"``.)
|
|
``expand-properties`` (default)
|
|
All string arguments are expanded as described in `Property Expansion`_.
|
|
|
|
|
|
All of the osd prefixes are still overridden by the global ``--osd-level``
|
|
settings.
|
|
|
|
Undocumented prefixes: ``pausing``, ``pausing_keep``, ``pausing_toggle``,
|
|
``pausing_keep_force``. (Should these be made official?)
|
|
|
|
Input Sections
|
|
--------------
|
|
|
|
Input sections group a set of bindings, and enable or disable them at once.
|
|
In ``input.conf``, each key binding is assigned to an input section, rather
|
|
than actually having explicit text sections.
|
|
|
|
Also see ``enable_section`` and ``disable_section`` commands.
|
|
|
|
Predefined bindings:
|
|
|
|
``default``
|
|
Bindings without input section are implicitly assigned to this section. It
|
|
is enabled by default during normal playback.
|
|
``encode``
|
|
Section which is active in encoding mode. It is enabled exclusively, so
|
|
that bindings in the ``default`` sections are ignored.
|
|
|
|
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 `Property Expansion`_.)
|
|
|
|
The ``W`` column indicates whether the property is generally writable. If an
|
|
option is referenced, the property should take/return exactly the same values
|
|
as the option.

Property Expansion
|
|
------------------
|
|
|
|
All string arguments to input commands as well as certain options (like
|
|
``--playing-msg``) are subject to property expansion.
|
|
|
|
.. admonition:: Example for input.conf
|
|
|
|
``i show_text "Filename: ${filename}"``
|
|
shows the filename of the current file when pressing the ``i`` key
|
|
|
|
Within ``input.conf``, property expansion can be inhibited by putting the
|
|
``raw`` prefix in front of commands.
|
|

The following expansions are supported:
|
|
|
|
``${NAME}``
|
|
Expands to the value of the property ``NAME``. If retrieving the property
|
|
fails, expand to an error string. (Use ``${NAME:}`` with a trailing
|
|
``:`` to expand to an empty string instead.)
|
|
If ``NAME`` is prefixed with ``=``, expand to the raw value of the property
|
|
(see below).
|
|
``${NAME:STR}``
|
|
Expands to the value of the property ``NAME``, or ``STR`` if the
|
|
property cannot be retrieved. ``STR`` is expanded recursively.
|
|
``${!NAME:STR}``
|
|
Expands to ``STR`` (recursively) if the property ``NAME`` cannot be
|
|
retrieved.
|
|
``${?NAME:STR}``
|
|
Expands to ``STR`` (recursively) if the property ``NAME`` is available.
|
|
``$$``
|
|
Expands to ``$``.
|
|
``$}``
|
|
Expands to ``}``. (To produce this character inside recursive
|
|
expansion.)
|
|
``$>``
|
|
Disable property expansion and special handling of ``$`` for the rest
|
|
of the string.
|
|
|
|
In places where property expansion is allowed, C-style escapes are often
|
|
accepted as well. Example:
|
|
|
|
- ``\n`` becomes a newline character
|
|
- ``\\`` expands to ``\``

Raw and Formatted Properties
|
|
----------------------------
|
|
|
|
Normally, properties are formatted as human-readable text, meant to be
|
|
displayed on OSD or on the terminal. It is possible to retrieve an unformatted
|
|
(raw) value from a property by prefixing its name with ``=``. These raw values
|
|
can be parsed by other programs and follow the same conventions as the options
|
|
associated with the properties.
|
|
|
|
.. admonition:: Examples
|
|
|
|
- ``${time-pos}`` expands to ``00:14:23`` (if playback position is at 14
|
|
minutes 23 seconds)
|
|
- ``${=time-pos}`` expands to ``863.4`` (same time, plus 400 milliseconds -
|
|
milliseconds are normally not shown in the formatted case)
|
|
|
|
Sometimes, the difference in amount of information carried by raw and formatted
|
|
property values can be rather big. In some cases, raw values have more
|
|
information, like higher precision than seconds with ``time-pos``. Sometimes
|
|
it is the other way around, e.g. ``aid`` shows track title and language in the
|
|
formatted case, but only the track number if it is raw.
