<span class="application">MPlayer</span> has a fully configurable, command
driven, control layer which lets you control
<span class="application">MPlayer</span> with keyboard, mouse, joystick or remote
control (using LIRC). See the man page for the complete list of keyboard controls.
</p><div class="sect2" title="3.3.1. Controls configuration"><div class="titlepage"><div><div><h3 class="title"><a name="ctrl-cfg"></a>3.3.1. Controls configuration</h3></div></div></div><p>
<span class="application">MPlayer</span> allows you bind any key/button to any
<span class="application">MPlayer</span> command using a simple config file.
The syntax consist of a key name followed by a command. The default config file location is
<tt class="filename">$HOME/.mplayer/input.conf</tt> but it can be overridden
using the <tt class="option">-input <em class="replaceable"><code>conf</code></em></tt> option
(relative path are relative to <tt class="filename">$HOME/.mplayer</tt>).
</p><p>
You can get a full list of supported key names by running
<span class="command"><strong>mplayer -input keylist</strong></span>
and a full list of available commands by running
<span class="command"><strong>mplayer -input cmdlist</strong></span>.

Linux Infrared Remote Control - use an easy to build home-brewed IR-receiver,
an (almost) arbitrary remote control and control your Linux box with it!
More about it on the <a class="ulink" href="http://www.lirc.org" target="_top">LIRC homepage</a>.
</p><p>
If you have the LIRC package installed, <tt class="filename">configure</tt> will
autodetect it. If everything went fine, <span class="application">MPlayer</span>
will print "<code class="systemitem">Setting up LIRC support...</code>"
on startup. If an error occurs it will tell you. If there is no message about
LIRC there is no support compiled in. That's it :-)
</p><p>
The application name for <span class="application">MPlayer</span> is - surprise -
<tt class="filename">mplayer</tt>. You can use any <span class="application">MPlayer</span>
commands and even pass more than one command by separating them with
<code class="literal">\n</code>.
Do not forget to enable the repeat flag in <tt class="filename">.lircrc</tt> when
it makes sense (seek, volume, etc). Here is an excerpt from a sample
<tt class="filename">.lircrc</tt>:
</p><pre class="programlisting">
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</pre><p>
If you do not like the standard location for the lirc-config file
(<tt class="filename">~/.lircrc</tt>) use the <tt class="option">-lircconf
<em class="replaceable"><code>filename</code></em></tt> switch to specify another
file.
</p></div><div class="sect2" title="3.3.3. Slave mode"><div class="titlepage"><div><div><h3 class="title"><a name="slave-mode"></a>3.3.3. Slave mode</h3></div></div></div><p>
The slave mode allows you to build simple frontends to
<span class="application">MPlayer</span>. When run with the
<tt class="option">-slave</tt> option <span class="application">MPlayer</span> will
read commands separated by a newline (\n) from stdin.
The commands are documented in the
<a class="ulink" href="../../tech/slave.txt" target="_top">slave.txt</a> file.
