<title>Command line</title>
<para>
<application>MPlayer</application> utilizes a complex playtree. It consists
of global options written as first, for example
<screen>mplayer -vfm 5</screen>
and options written after filenames, that apply only to the given
filename/URL/whatever, for example:
<screen>mplayer -vfm 5 movie1.avi movie2.avi -vfm 4</screen>
</para>
<para>
You can group filenames/URLs together using <literal>{</literal> and
<literal>}</literal>. It's useful with option <option>-loop</option>:
<screen>mplayer { 1.avi -loop 2 2.avi } -loop 3</screen>
The above command will play files in this order: 1, 1, 2, 1, 1, 2, 1, 1, 2.

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

<sect2 id="ctrl-cfg">
<title>Controls configuration</title>
<para>
<application>MPlayer</application> 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
<filename>$HOME/.mplayer/input.conf</filename> but it can be overridden
using the <option>-input <replaceable>conf</replaceable></option> option
(relative path are relative to <filename>$HOME/.mplayer</filename>).

<title>Control from LIRC</title>
<para>
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 <ulink url="http://www.lirc.org">www.lirc.org</ulink>.
</para>
<para>
If you have installed the lirc-package, configure will autodetect it. If
everything went fine, <application>MPlayer</application> will print a
message like "<computeroutput>Setting up lirc support...</computeroutput>"
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 :-)
</para>
<para>
The application name for <application>MPlayer</application> is - oh wonder
- <filename>mplayer</filename>. You can use any mplayer commands and even
pass more than one command by separating them with <literal>\n</literal>.
Don't forget to enable the repeat flag in <filename>.lircrc</filename> when
it make sense (seek, volume, etc). Here's an excerpt from my
<filename>.lircrc</filename>:
</para>
<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<!--
--></programlisting>
<para>
If you don't like the standard location for the lirc-config file
(<filename>~/.lircrc</filename>) use the <option>-lircconf
<replaceable>filename</replaceable></option> switch to specify another
file.
</para>

<sect2 id="slave-mode">
<title>Slave mode</title>
<para>
The slave mode allow you to build simple frontend to
<application>MPlayer</application>. When enabled (with the
<option>-slave</option> option) <application>MPlayer</application> will
read commands separated by new line (\n) from stdin.
</para>

<sect1 id="streaming">
<title>Streaming from network or pipes</title>
<para>
<application>MPlayer</application> can play files from network, using the
HTTP, FTP, MMS or RTSP/RTP protocol.
</para>
<para>
Playing goes by simply using adding the URL to the command line.
<application>MPlayer</application> also honors the
<envar>http_proxy</envar> environment variable, and uses proxy if
available. Proxy usage can also be forced:
<screen>mplayer http_proxy://proxy.micorsops.com:3128/http://micorsops.com:80/stream.asf</screen>
</para>
<para>
<application>MPlayer</application> can read from stdin
(<emphasis>not</emphasis> named pipes). This can be for example used to
play from FTP:
<screen>wget ftp://micorsops.com/something.avi -O - | mplayer -</screen>
</para>
<para>
Note: it's also recommended to enable CACHE when playback from network:
<screen>wget ftp://micorsops.com/something.avi -O - | mplayer -cache 8192 -</screen>
</para>
</sect1>
<sect1 id="mpst" xreflabel="Remote streams">
<title>Remote streams</title>
<para>
Remote streams allow you to access most <application>MPlayer</application>
stream type from a remote host. The main purpose of this feature is to make
it possible to directly use the CD or DVD drive of another computer on the
network (provided you have the required bandwidth). On the downside some
stream type (currently TV and MF) are not useable remotely because they are
implemented at the demuxer level. It's sad for MF but TV stream would anyway
require an insane amount of bandwith.
</para>
<sect2 id="compile_mpst_server">
<title>Compiling the server</title>
<para>
After having compiled <application>MPlayer</application> go to the
<filename>TOOLS/netstream</filename> directory and enter
<application>make</application> to build the server binary.
You can then copy the <application>netstream</application> binary
to the right place on your system (usually
<filename class="directory">/usr/local/bin</filename> on Linux).
</para>
</sect2>
<sect2 id="use_mpst">
<title>Using remote streams</title>
<para>
First you have to start the server on the computer you intend to remotely
access. Currently the server is very basic and doesn't have any commands
line arguments so just enter <filename>netstream</filename>. Now you can
for example play the second track of a VCD on the server with :
<screen>
mplayer -cache 5000 mpst://servername/vcd://2
</screen>
You can also access files on this server :
<screen>
mplayer -cache 5000 mpst://servername//usr/local/movies/lol.avi
</screen>
Note that paths wich aren't starting with a / will be relative to
the directory where the server is running. The cache option is not
needed but highly recommended.
</para>
<para>
Be aware that currently the server is not secure at all. So don't complain
about the numerous exploits wich are possible through this. Instead send
some (good) patch to make it better or start writing your own server.
