## 3.2. Control

MPlayer has a fully configurable, command driven, control layer which lets you control MPlayer with keyboard, mouse, joystick or remote control (using LIRC). See the man page for the complete list of keyboard controls.

### 3.2.1. Controls configuration

MPlayer allows you bind any key/button to any MPlayer command using a simple config file. The syntax consist of a key name followed by a command. The default config file location is `$HOME/.mplayer/input.conf` but it can be overridden using the `-input `conf`` option (relative path are relative to `$HOME/.mplayer`).

### 3.2.2. Control from LIRC

Linux Infrared Remote Control - use an easy to build home-brewn IR-receiver, an (almost) arbitrary remote control and control your linux box with it! More about it at www.lirc.org.

If you have installed the lirc-package, configure will autodetect it. If everything went fine, MPlayer will print a message like "`Setting up lirc support...`" on startup. If an error occurs it will tell you. If it doesn't tell you anything about LIRC there's no support compiled in. That's it :-)

The application name for MPlayer is - oh wonder - `mplayer`. You can use any mplayer commands and even pass more than one command by separating them with `\n`. Don't forget to enable the repeat flag in `.lircrc` when it make sense (seek, volume, etc). Here's an excerpt from my `.lircrc`:

    begin
         button = VOLUME_PLUS
         prog = mplayer
         config = volume 1
         repeat = 1
    end

    begin
        button = VOLUME_MINUS
        prog = mplayer
        config = volume -1
        repeat = 1
    end

    begin
        button = CD_PLAY
        prog = mplayer
        config = pause
    end

    begin
        button = CD_STOP
        prog = mplayer
        config = seek 0 1\npause
    end

If you don't like the standard location for the lirc-config file (`~/.lircrc`) use the `-lircconf `filename`` switch to specify another file.

### 3.2.3. Slave mode

The slave mode allow you to build simple frontend to MPlayer. When enabled (with the `-slave` option) MPlayer will read commands separated by new line (\n) from stdin.
