In this section I'll try to guide you through the compiling and configuring
process of <application>MPlayer</application>. It's not easy, but it won't
necessarily be hard. If you experience a different behavior than what I
explain, please search through this documentation and you'll find your
answers. If you see links, please follow them and read carefully what they
contain. It will take some time, but it IS worth it.

<emphasis role="bold">Never</emphasis> use 2.96 or 3.0.x! They generate faulty code for
<application>MPlayer</application>. If you decide to change gcc from
2.96, then don't decide in favor of 3.x just because it's newer! Early
releases of 3.x were even more buggy than 2.96. So downgrade to 2.95.x
(downgrade <systemitem class="library">libstdc++</systemitem> too, other
programs may need it) or don't up/downgrade at all (but in this case, be
prepared for runtime problems). If you vote for 3.x, try to use the
latest version, early releases had various bugs, so be sure you use at
least 3.1, it's tested and working. For detailed information about gcc 2.96's
bugs (that are still NOT fixed, they have been WORKED AROUND in

<application>MEncoder</application> can dump DVD subtitles into
<link linkend="menc-feat-extractsub">VOBsub</link> format.
</para>
<para>
The command line options differ slightly for the different formats:
</para>
<formalpara>
<title>VOBsub subtitles</title>
<para>
VOBsub subtitles consist of a big (some megabytes) <filename>.SUB</filename> file,
and optional <filename>.IDX</filename> and/or <filename>.IFO</filename>
files. If you have files like
<filename><replaceable>sample.sub</replaceable></filename>,
<filename><replaceable>sample.ifo</replaceable></filename> (optional),
<filename><replaceable>sample.idx</replaceable></filename> - you have to pass
<application>MPlayer</application> the <option>-vobsub sample
[-vobsubid <replaceable>id</replaceable>]</option> options
(full path optional). The <option>-vobsubid</option> option is like
<option>-sid</option> for DVDs, you can choose between subtitle tracks
(languages) with it. In case that <option>-vobsubid</option> is omitted,
<application>MPLayer</application> will try to use the languages given by the
<option>-slang</option> option and fall back to the <systemitem>langidx</systemitem>
in the <filename>.IDX</filename> file to set the subtitle language. If it fails,
there will be no subtitles.
</para>
</formalpara>
<formalpara>
<title>Other subtitles</title>
<para>
The other formats consist of a single text file containing timing,
placement and text information. Usage: If you have a file like
<filename><replaceable>sample.txt</replaceable></filename>,
you have to pass the option <option>-sub
<replaceable>sample.txt</replaceable></option> (full path optional).

<para>
If you experience a growing delay between the movie and the subtitles when
using a MicroDVD subtitle file, most likely the frame rate of the movie and
the subtitle file are different. Please note that the MicroDVD subtitle
format uses absolute frame numbers for its timing, but there is no fps
information in it, and therefore the <option>-subfps</option> option should
be used with this format. If you like to solve this problem permanently,
you have to manually convert the subtitle file framerate.
<application>MPlayer</application> can do this
conversion for you:
<screen>mplayer -dumpmicrodvdsub -fps <replaceable>subtitles_fps</replaceable> -subfps <replaceable>avi_fps</replaceable> -sub <replaceable>subtitle_filename</replaceable> <replaceable>dummy.avi</replaceable></screen>

<sect2 id="mpsub">
<title><application>MPlayer</application>'s own subtitle format (MPsub)</title>
<para>
<application>MPlayer</application> introduces a new subtitle format called
<emphasis role="bold">MPsub</emphasis>. It was designed by Gabucino. Basically
its main feature is being <emphasis>dynamically</emphasis> time-based (although
it has frame-based mode too). Example (from <ulink
url="../../tech/mpsub.sub">DOCS/tech/mpsub.sub</ulink>):
<programlisting>
FORMAT=TIME
# first number : wait this much after previous subtitle disappeared
# second number : display the current subtitle for this many seconds

</para>
<para>
So you see, the main goal was to <emphasis role="bold">make subtitle
editing/timing/joining/cutting easy</emphasis>. And, if you - say - get an
SSA subtitle but it's badly timed/delayed to your version of the movie, you
simply do a
<screen>mplayer <replaceable>dummy.avi</replaceable> -sub source.ssa -dumpmpsub</screen>
A <filename>dump.mpsub</filename> file will be created in the
current directory, which will contain the source subtitle's text, but in
<emphasis role="bold">MPsub</emphasis> format. Then you can freely add/subtract
seconds to/from the subtitle.
</para>
<para>
Subtitles are displayed with a technique called <emphasis role="bold">'OSD',
On Screen Display</emphasis>. OSD is used to display current time, volume bar,
seek bar etc.

</para>

RAW plugin too, see <ulink url="http://realtime.ssu.ac.kr/~lethean/index.php?pagename=MplayerKoreanFonts" />).
</para></listitem>
<listitem><para>
using a TrueType (TTF) font, by the means of the <systemitem class="library">freetype</systemitem>
library. Version 2.0.9 or greater is mandatory! Then you have two methods:
<itemizedlist>
<listitem><para>
use the <option>-font <replaceable>/path/to/sample_font.ttf</replaceable></option>
option to specify a TrueType font file on every occasion
</para></listitem>
<listitem><para>
create a symlink:
<screen>ln -s <replaceable>/path/to/sample_font.ttf</replaceable> ~/.mplayer/subfont.ttf</screen>
</para></listitem>
</itemizedlist>
If <application>MPlayer</application> was compiled with
<systemitem class="library">fontconfig</systemitem> support, the above methods
won't work, instead the <option>-font</option> expects a
<systemitem class="library">fontconfig</systemitem> font name
and defaults to the sans-serif font. To get a list of fonts known to
<systemitem class="library">fontconfig</systemitem>,
use <command>fc-list</command>. Example: <option>-font
<replaceable>'Bitstream Vera Sans'</replaceable></option>
</para></listitem>
<listitem><para>
Download ready-to-use font packages from <application>MPlayer</application>
site. Note: currently available fonts are limited for ISO 8859-1/2 support,
but there are some other (including Korean, Russian, ISO 8859-8 etc) fonts at
contrib/font section of FTP, made by users.
</para><para>
<!-- FIXME: this para should be before the list -->
Font should have appropriate <filename>font.desc</filename> file which
maps unicode font positions to the actual code page of the subtitles
text. Other solution is to have subtitles encoded in UTF-8 encoding and
use <option>-utf8</option> option or just name the subtitles file
<filename>&lt;video_name&gt;.utf</filename> and have it in the same dir
as the video file. Recoding from different codepages to UTF-8 could be
done by using <command>konwert</command> or <command>iconv</command> programs.

If you chose non-TTF fonts, UNZIP the file you downloaded to <filename

<title>RTC</title>
<para>
There are three timing methods in <application>MPlayer</application>.
<itemizedlist>
<listitem><simpara>
<emphasis role="bold">To use the old method</emphasis>, you don't have to do
anything. It uses <systemitem>usleep()</systemitem> to tune
A/V sync, with +/- 10ms accuracy. However sometimes the sync has to be
tuned even finer.
</simpara></listitem>
<listitem><para>
<emphasis role="bold">The new timer</emphasis> code uses the RTC (RealTime Clock)
for this task, because it has precise 1ms timers. It is automagically enabled
when available, but requires root privileges, a <emphasis>setuid root</emphasis>
<application>MPlayer</application> binary or a properly set up kernel.
If you are running kernel 2.4.19pre8 or later you can adjust the maximum RTC
frequency for normal users through the <systemitem class="systemname">/proc
</systemitem> filesystem. Use this command to
enable RTC for normal users:
<screen>echo 1024 &gt; /proc/sys/dev/rtc/max-user-freq</screen>
If you do not have such a new kernel, you can also change one line in
<filename>drivers/char/rtc.c</filename> and recompile your kernel.
Find the section that reads
<programlisting>
* We don't really want Joe User enabling more
* than 64Hz of interrupts on a multi-user machine.
*/
if ((rtc_freq &gt; 64) &amp;&amp; (!capable(CAP_SYS_RESOURCE)))
</programlisting>
and change the 64 to 1024. You should really know what you are doing, though.
You can see the new timer's efficiency in the status line.
The power management functions of some notebook BIOSes with speedstep CPUs
interact badly with RTC. Audio and video may get out of sync. Plugging the
external power connector in before you power up your notebook seems to help.
You can always turn off RTC support with the <option>-nortc</option> option.
In some hardware combinations (confirmed during usage of non-DMA DVD drive
on an ALi1541 board) usage of the RTC timer causes skippy playback. It's
recommended to use the third method in these cases.
</para></listitem>
<listitem><simpara>
<emphasis role="bold">The third timer code</emphasis> is turned on with the
<option>-softsleep</option> option. It has the efficiency of the RTC, but it
doesn't use RTC. On the other hand, it requires more CPU.
