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.

Configuration
-------------

The OSC offers limited configuration through a config file ``plugin_osc.conf``
placed in mpv's user dir.

Config Syntax
~~~~~~~~~~~~~

The config file must exactly follow the following syntax::

    # this is a comment
    parameter1=value1
    parameter2=value2

``#`` can only be used at the beginning of a line and there may be no
spaces around the ``=`` or anywhere else.

Configurable parameters
~~~~~~~~~~~~~~~~~~~~~~~

``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.

``minmousemove``
    | Default: 3
    | Minimum amount of pixels the mouse has to move between ticks to make
      the OSC show up
