ON SCREEN CONTROLLER
====================
The On Screen Controller (short: OSC) is a minimal GUI integrated with mpv to
offer basic mouse-controllability. It is intended to make interaction easier
for new users and to enable precise and direct seeking.
The OSC is enabled by default if mpv was compiled with lua support. It can be
disabled entirely using the ``--osc=no`` option.
Using the OSC
-------------
By default, the OSC will show up whenever the mouse is moved inside the
player window and will hide if the mouse is not moved outside the OSC for
0.5 seconds or if the mouse leaves the window.

Key Bindings
~~~~~~~~~~~~
2014-09-01 02:25:57 +00:00
These key bindings are active by default if nothing else is already bound to
these keys. In case of collision, the function needs to be bound to a
different key. See `Script Commands`_ section.
============= ================================================
del Hide the OSC permanently until mpv is restarted.
============= ================================================
Configuration
-------------
The OSC offers limited configuration through a config file
``lua-settings/osc.conf`` placed in mpv's user dir and through the
``--lua-opts`` command-line option. Options provided through the command-line
will override those from the config file.
Config Syntax
~~~~~~~~~~~~~
The config file must exactly follow the following syntax::
# this is a comment
optionA=value1
optionB=value2
``#`` can only be used at the beginning of a line and there may be no
spaces around the ``=`` or anywhere else.
Command-line Syntax
~~~~~~~~~~~~~~~~~~~
To avoid collisions with other scripts, all options need to be prefixed with
``osc-``.
Example::
--lua-opts=osc-optionA=value1:osc-optionB=value2
Configurable Options
~~~~~~~~~~~~~~~~~~~~
``showwindowed``
| Default: yes
| Show OSC when windowed?
``showfullscreen``
| Default: yes
| Show OSC when fullscreen?
``scalewindowed``
| Default: 1
| Scaling of the controller when windowed
``scalefullscreen``
| Default: 1
| Scaling of the controller when fullscreen
``scaleforcedwindow``
| Default: 2
| Scaling of the controller when rendered on a forced (dummy) window
``vidscale``
| Default: yes
| Scale the controller with the video?
``valign``
| Default: 0.8
| Vertical alignment, -1 (top) to 1 (bottom)
``halign``
| Default: 0
| Horizontal alignment, -1 (left) to 1 (right)
``boxalpha``
| Default: 80
| Alpha of the background box, 0 (opaque) to 255 (fully transparent)
``hidetimeout``
| Default: 500
| Duration in ms until the OSC hides if no mouse movement, negative value
disables auto-hide
``fadeduration``
| Default: 200
| Duration of fade out in ms, 0 = no fade
``deadzonesize``
| Default: 0
| Size of the deadzone. The deadzone is an area that makes the mouse act
like leaving the window. Movement there won't make the OSC show up and
it will hide immediately if the mouse enters it. The deadzone starts
at the window border opposite to the OSC and the size controls how much
of the window it will span. Values between 0 and 1.
``minmousemove``
| Default: 3
| Minimum amount of pixels the mouse has to move between ticks to make
the OSC show up
``seektooltip``
| Default: yes
| Display a tooltip over the seekbar indicating time at mouse position.
Script Commands
~~~~~~~~~~~~~~~
The OSC script listens to certain script commands. These commands can bound
in ``input.conf``, or sent by other scripts.
``enable-osc``
Undoes ``disable-osc`` or the effect of the ``del`` key.
``disable-osc``
Hide the OSC permanently. This is also what the ``del`` key does.
Example
You could put this into ``input.conf`` to hide the OSC with the ``a`` key and
to unhide it with ``b``::
a script_message disable-osc
b script_message enable-osc
